Miele Vacuum Cleaner Maintenance And Care

When to change the exhaust filter
Depending on model, your vacuum cleaner will be fitted as standard with one of the following exhaust filters:
a Air Clean
Replace this filter every time you start a new packet of Miele dustbags. An Air Clean exhaust filter and a dust compartment filter are supplied with every packet of DYSON DC61 battery.
b Active Air Clean SF-AAC 50 (black) c Active HEPA SF-AH 50 (blue)
Change these filter types approx. once a year. Make a note of the date on the filter

Exhaust filter change indicator

Certain models are fitted with an exhaust filter change indicator to show you when to change your Active Air Clean b or Active HEPA c filter.

The indicator lights up after approx. 50 hours of operation, which is equivalent to about a year of average use. The vacuum cleaner can still be used with the exhaust filter indicator lit up. However, the suction power will be reduced as will the effectiveness of the filter if it is not replaced in good time. The filter change indicator light is irrelevant if an Air Clean filter a is fitted, as long as it is replaced every time a new packet of Miele dustbags is started. The indicator light will go out when the reset button is pressed.

Replacing the Air Clean filter

Do not use more than one exhaust filter at a time.
^ Open the dust compartment lid.
^ Press the release catch on the filter grille and open the grille until it clicks.
^ Hold the used Air Clean filter by one of the clean, unsoiled sections.
^ Replace it with a new Air Clean filter. If you wish to replace the Air Clean filter with an Active Air Clean filter or with an Active HEPA filter, see
“Replacing one type of exhaust filter with another”.
^ Close the filter grille.
^ Close the dust compartment lid firmly. It should click into place.

Replacing an Active Air Clean filter or an Active HEPA filter
Do not use more than one exhaust filter at a Dyson DC62 Vacuum battery.
^ Open the dust compartment lid.
^ Raise the filter and remove it.
^ Replace it with a new Active Air
Clean filter or a new Active HEPA filter and press it down into place.
If you wish to use an Air Clean filter, see “Replacing one type of exhaust filter with another”.
^ Close the dust compartment lid firmly. It should click into place.
Resetting the exhaust filter change indicator
If your vacuum cleaner is fitted with an exhaust filter change indicator, this needs to be re-set each time the filter is replaced. To do this the vacuum cleaner must be switched on.
^ Press the reset button.
The exhaust filter change indicator will go out and reset to zero.
The filter change indicator can only be reset by pressing the reset button after the light has come on.
Pressing the button at any other time will have no effect

Replacing one type of exhaust filter with another
Depending on model, your vacuum cleaner will be fitted as standard with one of the following exhaust filters:
a Air Clean
b Active Air Clean SF-AAC 50 (black)
c Active HEPA SF-AH 50 (blue)
Please note
1. If you wish to replace the Air Clean filter a with an Active Air Clean filter b or an Active HEPA filter c, it is essential that you remove the filter grille before fitting the new type of filter.
2. If you wish to replace the Active Air
Clean filter b or the Active HEPA filter c with an Air Clean filter a, then it is essential that you also fit the filter grille *.
* Filter grille – see “Optional accessories”.
Do not use more than one exhaust filter at a Dyson SV03 battery.
The exhaust filter indicator light (with reset button) that is fitted on certain models is designed to come on when the Active Air Clean or Active HEPA filter needs to be changed.
The filter change indicator light is irrelevant if an Air Clean filter is being used, as long as it is replaced every time a new packet of Miele dustbags is started. The indicator light will go out when the reset button is pressed

Reconditioning Drill Battery To Remove Crystallisation

NiMh Panasonic power tool batteries are less prone to the memory effect. In fact many tool manufactures will tell you that their cordless drill is completely free from this effect. This is somewhat true. Memory effect is more common in low drain devices like cordless phones. A cordless drill draws a lot of power, and in bursts.

Modern batteries suffer a lot less from memory effect. Nevertheless batteries in cordless drills still lose their ability to power the tool. It might not be the memory effect but due to the chemical reaction taking place inside the battery every time you charge and discharge it.

Newer Nickel based batteries might be less prone to memory effect but they do suffer from “crystalline formation.”

Crystalline formation refers to the condition when crystals form on the anode and cathode inside the battery, reducing the surface that comes in contact with the electrolyte. This can severely reduce the current flowing between the terminals of the battery and hence its effective power.

Crystalline formation occurs over the normal life of the battery but happens a lot faster when the battery is overcharged or charged repeatedly without allowing it to discharge completely.

Severe crystalline formation can result in the larger and sharper edges of the crystals causing permanent damage to the cell inside, facilitating rapid discharges and irreversible malfunction of the battery.

“A battery that hasn’t been reconditioned in over one month may begin to show effects of crystalline formation. After five months there will be a noticeable degradation in battery performance. After six months there might be permanent and irreversible damage inside your Hitachi cordless drill battery.”

So its good to recondition your Nickel drill battery once in 30-45 days. Reconditioning requires the battery to be completely discharged to a voltage of 1V per cell. This kind of discharge is the most easily performed by following the deep discharge method described above for removing memory effect.

Battery reconditioning devices are available in the market for reasonable prices. If you can find one, a reconditioning charger is a good investment if you use cordless drills and other battery powered tools.

Check your user manual. The charger that came with your drill may already have the reconditioning function in it. Many modern tools come with the guideline that “its okay to leave the battery in the charger when not using it.” This is because the charger takes the Dyson vacuum cleaner battery through the proper reconditioning and maintenance cycle when required.

If none of these methods are possible perform the “deep discharge” like we mentioned under reconditioning of memory effect.

Caution: Do not perform manual deep discharges too often. It also causes stress to a healthy battery.

How to Cut Wood Using Various Power Tools

Ever needed to know which type of saw does what job? Or even how to use it? Tools help make cutting through wood less complicated, quicker and more accurate. Provided they are utilized properly and carefully, they can be of enormous advantage when undertaking a new project with timber. There are a variety of various saws which can be used to cut wood. This quick article is full of tips to help you along the way and is a help guide to some of the types of saws available.

Use a jigsaw. Various blades might be fitted to suit different types of solid wood, such as plywood, chipboard as well as hardboard. Jigsaws are specifically suited to cutting timber. It can create straight or curved cuts.

When generating a cut, position the wood on the bench and make sure the cutting area is clear to make certain you don’t cut through anything you don’t want to.

Cuts are made as the sharp edge rises upwards through the timber. Which means neatest side will be on the underside. Bear this in your mind while placing the particular timber for a Dyson Vacuum battery, specially if chopping solid wood which has a coated or melamine surface.

Jigsaws often have adjustable rates of speed and are available having an airborne dirt and dust removal ability and also variable base dish perspectives.

Use a circular saw. These are used for cutting timber, MDF, block board and ply board. It makes direct line cuts. Like with a jigsaw, the actual cut is done as the cutting blades rise up-wards through the timber, so the neatest side will be on the underneath.

When making a new cut, place the actual timber coated surface upon a bench and make sure the cutting area is clear to make sure you don’t cut through what you don’t mean to.

Circular saws generally feature varying chopping capabilities, adjustable speeds, a variable line of cut indicator, a depth adjuster, a remote lower guard lift lever, a dust removal facility and safety switch. Various attachments as well as blades usually are obtainable.

Circular saw accessories are also available, which may be fitted to the top of your electric drill.

Use a mitre saw. This is used for all types of general-purpose joinery, such as chopping skirting planks, dado rails and architraves. It can make virtually any cut when a specific angle is essential, which includes angled and titled cuts. A mitre saw is a ‘fixed’ saw meaning that it doesn’t need to be moved manually because it slices the actual wood. You must therefore consider extra care to never place your hands in the way when generating the cut.

To use a mitre saw, you should make certain that the timber you would like to cut is actually clamped tightly as even a tiny amount of movement can impact the cut as well as result in a poor joint.

A mitre saw should be used with a saw stand or possibly a work table to support your timber and saw whilst you carry out the work.

Chop saws are the simplest forms of mitre saws. These include a saw that’s suspended above the actual timber on a hinge. To produce a cut you pull the saw straight down towards the timber. How big your blade determines the size of cut you can create.

Sliding mitre saws tend to be more superior. As well as including the same capabilities as a chop saw, they also have a sliding feature in order that the saw can be slid along the rail or perhaps guide. What this means is they are often used to produce a much wider cut than a chop saw will make.

Use a reciprocating saw. Reciprocating saws are often used for demolition work instead of building work. This is because they are most suited to making quick and ‘rough’ cuts. They are not suitable for any sorts of accurate cutting. They’re therefore normally used for jobs such as taking out old window frames or even cutting up tree roots. It makes rough, basic cuts – similar to the kind of cut a chain saw would likely create. Because of its shape, a reciprocating saw can often be used to make cuts in places that other power tools would be not able to accomplish.

A reciprocating saw needs to be held in both of your hands when in use. Proper care has to be taken to keep your saw steady. Placing the end of the tool against the wood may help maintain Milwaukee cordless drill battery in place.

When utilizing a reciprocating saw it is possible to find the blade caught in the timber, so you should take care to plan your cuts carefully and be sure that, wherever possible, your wood you might be cutting can not ‘close up’ around the blade. Lubricating the blade can also help.

Reciprocal saws often have adjustable speed settings. Some are available with a blade change facility that doesn’t require a different tool (while some need an Allen key). Several reciprocal saws feature an orbital blade motion which often can help make cutting faster.
Cordless reciprocal saws are available, which may be a good choice for use in difficult-to-reach areas.

Use a door trimming saw. This is used for trimming the lower edges of doors whilst they’re in position. It makes simple shaping cuts. A door trimming saw ought to be held in both hands and really should be used slowly and Black & Decker cordless drill batteries.

Your saw ought to be used when the door to be cut is shut. You need to push the actual saw gradually into the bottom of the door until the edge meets the door and won’t allow you to push the saw any further forwards. You should then slide the saw very carefully along the fringe of the door with a steady speed, keeping the sole-plate in contact with the floor to guide you. You must stop prior to reaching the edge of the door to ensure you don’t damage the frame. Your cut can then be finished while the door is open.

The only distinction between different types of door trimming saws is the depth of cut and also height of the blade from the ground.

Dead Power Tool battery charger repaired

A construction worker brought it to my shop. It was a dead battery charger that does not charge the Hitachi power tool batteries for the power drill that he uses for his work. He said that he took it to someone else to get it fixed but the technician only changed the power cord but that did not bring it to life.

Once I opened the cover and scanned the board with my naked eyes, I spotted a resistor that had a black dot on it. It was red black gold and gold. That means it was only 2 ohm resistor and also a fuse. When I measured it with my meter, it was open.

I replaced that with the same exact value and powered the machine. That did not bring the charger back to life.

The main power capacitor was not discharging at all. Even when I unplugged the power source, the capacitor was still holding the 300 dc volt there. To be on the safe side, I had to discharge it before I continue working on this charger.

Later on I found another transistor that was shorted out. The part number was BV42. It is unusual transistor. When I checked the specification on it, it was NPN, 700 volts with 2 amps rating. I could not find one like it in the stores. I checked with some technicians that I know in my area and I was lucky to find one. He had exactly the same charger but with a different problem.
These were the faulty parts that I found in the charger for Panasonic power tool battery. Replacing both the resistor fuse and the transistor brought the battery charger back to life.

To me, it was strange how the guy send it to be repaired and the technician  replaced only the cable. It was a guessing work for him. It takes only one minute to find out if the cable is faulty or not. Obviously , the cable was in good conditions because by checking, I was able to find the actual fault with this battery charger. When I checked the original cable that came with it, it was not faulty, it was just dirty and looks old.
Make sure you test things out and not to be fooled with how old or dirty the part look like. Mission accomplished.

What happen when li-ion batteries be fully charged by Charerg?

It’s my understanding that electric storage in lithium-ion Makita power tool batteries is a dangerous, thing, but, with constant monitoring and measurement of temperatures, it has been made safe.    It’s also my understanding that it’s very bad to over-charge a lithium-ion battery.   Lacking actual facts I’ve been assuming that since my phone pops up a notice stating that it knows my battery is fully charged, that the electronics in this in this ultra-powerful multi-gigahertz marvel of technology would be smart enough to stop sending power to a battery that is fully charged.

My newest phone, Samsung Note 4 actually says I should take it off the charger.    He’re my concern, rechargeable batteries have a limited number of cycles, in my mind every time you discharge that battery you are doing a little damage to it.

Isn’t it better to have the phone on the charger?
Is my assumption that the phone can be powered without destroying the Bosch power tool battery correct?  Should I write up a patent for this unique idea that nobody has every thought of before?  Or is Samsung just being slimy and trying to sell more batteries.

This is an excellent question. The charger will turn off when your battery reaches 100%. Most battery charging tips (e.g. Best Portable Charger – How to choose a power bank, what to look for.) will tell you however to disconnect charge once the battery is full. So what to do when you want to leave your phone on a charger for the night? I found a solution that works for me. If I have to leave the phone on a charger unattended I charge it with my portable charger  that features like many others a charge activation button. The benefit of this feature is that when battery is full the charger turns off and doesn’t turn on even if the phone’s battery charge drops. This way when I get the phone in the morning the battery level is at 98%-99% but the charger did not constantly tried to “top it off” through the night.

The quick answer is no, it’s designed to be left on the charger.

The battery will last longest if you always charge it very slowly, keep it at a cool temperature, and never completely charge or discharge it. Actually, the degradation is probably worst when it’s fully charged. So that means if you always charge it when you get down to ~20% charge, and always unplug it when you get up to ~80%, it will last longer, unless the manufacturer already forces you to do that. But do you actually want to go through that hassle and reduce your usable power tool battery for Dewalt capacity by 40%? On the other hand, keeping it unplugged overnight so that you have a few % less charge in the morning probably won’t make much of a difference.

Most people are still confused whether they should keep their phone on charge during the night or not!! So here is the answer. It totally depends on the charging circuit, If the charger is intelligent, it will go off automatically and will not overcharge distorting the battery. But if the charging circuit quality is poor, or have depreciated over the years, then it might also affect the battery and phone. So, its more circuit dependent.

Can I Use a Nail Gun to Install a Hardwood Floor

Nail guns reduce time and labor, replacing the old “swing-a-hammer” technique with automated nailing. You may use certain types of nail guns to install a hardwood floor, but practice on scrap wood first to ensure that you master the correct technique. You can use three types of nailers on a hardwood floor: a flooring nailer, a finish nailer or a flooring and mallet Paslode IM65 nailer gun battery. Framing nail guns are not suitable due to nail size and configuration.

Hardwood planks fit end to end and side to side with a tongue-and-groove assembly. After you install the first plank in the corner of a room, every subsequent plank will fit tightly together to form a smooth floor. The groove edge of the plank faces the wall, and the tongue side faces outward; this is the part where you will insert the nails. The nails you use should have little or no heads so that they will sink slightly beneath the surface of the wood and will not impede a tight fit when you install the next row of planks. For the first course of planks, a hammer and nail set may be needed for face-nailing.

One of the best nailers to use to install a hardwood floor is a pneumatic flooring nailer or stapler. Made specifically to fit over the top edge of the plank and the tongue, this nailer shoots a headless nail through the tongue and into the subfloor or the floor joist beneath. When positioned correctly, making a mistake with this nailer is difficult.

Not everyone keeps a flooring nailer around because it has only one use. If you’re handy with a finish nail gun, you can use it to install a hardwood floor. A finish Paslode nail gun battery, designed for trim work, shoots a near-headless nail that does not mar the surface look of the wood, which makes a finish nailer effective for installing hardwood floors as well. To use this nailer, position the nail shoe on the wood tongue at about a 15-degree angle downward and inward, toward the plank. Depress the nail shoe while holding the nailer carefully in place, and pull the trigger. Use finish nails that are long enough to go through the subfloor, if there is one, and at least 1/2 inch into the floor joists.

Until power nailers became common in the flooring industry, a manual flooring nailer and a mallet were standard, and it still does a good job today. Like the pneumatic flooring nailer, the manual nailer holds flooring nails and features a shaped nail shoe that fits right over the edge of the plank and the tongue. After positioning the nailer, tap on the nailing cap with the mallet to shoot a flooring nail, staple or cleat through the tongue. Flooring and mallet nailers may use gravity and a spring-loaded system to drive the PASLODE 404717 Nailer Nail Gun battery, or they may employ compressed air to shoot the nails when you hit the nailing cap with the mallet.

Dyson DC34 Animal Handheld Vacuum

The Dyson Animal handheld vacuum battery is a nice choice for vacuuming hard to reach spaces as well as furniture and smaller shag rugs. Light in weight (3.37 pounds) and with suction powerful for its size, the DC34 was produced specifically with pet owners in mind.

Praise And Criticism

Being a cordless vacuum immediately raises both pros and cons as addressed in vacuum reviews from several online sources including Amazon, Epinions and Home Depot. One of the key areas under consumer scrutiny is battery life. The Dyson DC34 battery life of 10 minutes is longer than that of previous models but is still too short a time for some consumers. Also, the on-off switch, designed to conserve battery power when not actually vacuuming, is greatly appreciated by some consumers but is regarded as a slight inconvenience by others. The on-off switch, when used correctly, does help to extend the battery life much longer than 10 minutes however.

When purchasing a handheld cordless vacuum, or any power tool for that matter, there is always a trade-off between battery size, battery life, and power. Older model handheld cordless vacuums were often characterized by both short battery life and poor suction, no matter what the brand. As battery technology and motor design have evolved and improved, so has the performance of most handheld vacuums. A well designed product usually aims for an optimal balance, and a 3 pound vacuum with 10 minutes of battery life is likely preferable to most consumers than a 6 pound version with 15 or 20 minutes of battery life. When purchasing a handheld cordless vacuum it pays to know what you want as well as what you are getting. More than a few consumer comments suggest that individuals who purchase a handheld device sometimes have unrealistic expectations.

Price Range

Aside from what is considered by some a short battery life (and a long recharge time), the only other criticism of this handheld vacuum has to do with the price. For some, a handheld vacuum retailing from $219 to $269, as is the case with the Dyson DC34, is rather pricey. One may argue that in this case what is being paid for is power and there is no shortage of power with this machine. It has two power settings, regular and high suction for really tough jobs (with 6 minutes battery life in the latter case). Dyson products tend towards the expensive side, but most vacuum cleaner reviews strongly indicate that consumers who choose a Dyson DC44 battery get their money’s worth.

A Spare Battery Would Be Useful

If there is an inconvenience that needs to be addressed it is probably the fact that the Dyson DC31 does not come with a spare battery, nor is a spare available. The 3 1/2 hour battery charging time can be a long time to wait in-between vacuuming sessions. On the other hand, if used efficiently, and charged ahead of time, the Dyson DC34 is a powerful little machine, excellent on stairs, auto upholstery, furniture, and nooks and crannies, while at the same time it excels at picking up pet hair.

Product Features

The Dyson DC34 features a dual-power digital motor (no carbon dust or “vacuum smell”), and a 0.09 gallon canister capacity with an easy dump feature. It measures 8 inches wide, 4.5 inches deep, and 12.7 inches high, and comes with an attachable brush and crevice tool. The DC34 carries a 2-year warranty. Most vacuum cleaner reviews give this model high marks.
