Frequently Asked Questions - DWS 90 EINHELL

What is the maximum working pressure of the DWS 90 compressor?

The maximum working pressure is 6 bar.

How to lubricate the pneumatic tool?

Before each use, pour 3 to 5 drops of special machine oil into the compressed air connection. If the tool has been unused for several days, pour 5 to 10 drops.

Can I use a small-diameter air hose?

It is recommended to use a hose with an inner diameter of at least 9 mm to avoid power loss.

What tools are included in the DWS 90 kit?

The kit includes a universal motor, a drill chuck (∅1.5-10 mm), a plug-in connector R 1/4", a chuck key, a grinding wheel holder on a ∅6 mm shaft, two fork wrenches (11/17 mm), a belt file, and two abrasive belts (330x10 mm).

What is the power of the compressor?

The filling power is approx. 250 l/min, corresponding to a motor capacity of 2.2 kW.

How to mount the belt sander?

Remove the drill chuck or the grinding wheel holder, screw the guide roller onto the tool, tighten with the provided wrenches, place the belt sander, and tighten with the hex key. Insert the abrasive belt respecting the rotation direction indicated by the arrow.

Is it safe to use the tool near flammable materials?

No, be careful of sparks thrown during grinding. Keep flammable materials such as hay, shavings, or paints away.

What to do if the tool loses power?

Check that the air hose has a sufficient diameter (∅9 mm min.) and is not too long. Also ensure that the working pressure is set to 6 bar.

How to maintain the pneumatic tool?

Regularly lubricate the pneumatic motor via an oil mist lubricator or manually. Have the device serviced by a specialist at least every 3 months.

4. Proper use

The universal sander/grinder is a pneumatic tool for universal service. It is suitable e.g. for use in workshops, DIY, hobbies and automotive bodywork departments.

The exhaust air leaves the tool to the front.

Repairs and maintenance work are to be carried out only by authorized specialist workshops.

Please note!

The power of the tool will be reduced if you use a hose that has too small an inner diameter or which is too long.

5. Safety regulations

Take suitable precautions to protect yourself and your environment from potential hazards.

• Never put the universal sander/grinder to any use other than that intended. Be careful with combustible materials - sparking is possible. Keep pneumatic tools safe from children.
  ●Always concentrate while you work. Do not work if you are tired.
• Use only a quick-release coupling to connect up the air supply.
• It is imperative to use a pressure reducer to set the working pressure.
  ●Never use oxygen or combustible gases as an energy source.
  ●Always disconnect the tool from the air supply before carrying out any repairs or maintenance work.
  ●Never allow the tool to run unloaded at full idle speed for any length of time.
  ●Wear the necessary protective clothing, particularly goggles and safety gloves, when working with the universal sander/grinder.
  ●Watch out for sparks when grinding. Hot flying particles may burn into both soft and hard materials (glass, floor coverings, etc.) or ignite inflammable solids and liquids (hay, saw dust, lacquers, etc.).

Abrasives

• Use only organically bonded abrasive wheels and organically or inorganically bonded grinding pins and small abrasive wheels (wheel ∅ smaller than 20 mm).
• Under no circumstances are you to use abrasive wheels at speeds higher than the speed quoted in rpm by the wheel's manufacturer.
• Allow new abrasive wheels (and all re-mounted abrasive wheels) a running-in period of 30 seconds on the tool on which they are to be used. Operators and other personnel are to stay out of the danger zone during the trial run.
  ●Never halt an abrasive wheel by pressing on its circumference or face.
  ●Tighten the lock nut only enough to hold the abrasive wheel securely in place.
• Operators are to be thoroughly instructed on how to use the sanding/grinding tool safely.

●Make sure that the air hose connections and hose couplings are tight and that the air pressure is the same as that specified in the instructions.
●Examine grinding pins for signs of damage before using them for the first time and then regularly every day.
●Handle grinding pins and other abrasives carefully. Do not drop. Avoid knocks.
- Make sure the pneumatic motor and the tool's bearings are kept properly lubricated, ideally by means of an oiler in the compressed air line.
●Regular overhauls by a specialist (at least every 3 months, depending on how the tool is used) will ensure troublefree operation and good performance.
- When fitting a grinding pin, be sure to leave a gap of at least 1 cm between the back of the abrasive and the tool lock nut.

6. Putting into operation

Screw the supplied plug-in nipple into the air connection after you have wound 2 to 3 layers of sealing tape around the thread.

7. Maintenance and cleaning

Observance of the following maintenance instructions will ensure that this quality tool gives you years of troublefree service.

Regular lubrication is vital for the long-term, reliable operation of your universal sander/grinder. Use only special tool oil for this purpose.

You can choose from the following options for lubricating the tool:

7.1 By mist oiler

A complete conditioning unit includes a mist oiler and is fitted to the compressor.

7.2 By hand

Each time before you use your universal sander/grinder, feed 3-5 drops of special tool oil into the air connection. If the pneumatic tool has not been used for several days, you must feed 5-10 drops of oil into the air connection before you switch on.

Keep your pneumatic tool in dry rooms only.

The warranty does not cover:

●Wearing parts
●Damage caused by an unacceptable level of working pressure.
●Damage caused by unconditioned compressed air.
●Damage caused by improper use or unauthorized tam
