Proper use

The pin grinder is a handy pneumatic tool for use in DIY and automotive workshops.
The exhaust air leaves the tool through the outlet to the rear. The air supply is connected to the tool by means of a quick-release coupling.
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.

Safety regulations

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

Never put the pin grinder to any use other than that intended.
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.
Use only original replacement parts.
Never allow the tool to run unloaded at full idle speed for any considerable length of time.
Wear the necessary protective clothing when working with the pin grinder.
Always wear goggles when grinding.
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, lacquer, etc.).
Never use the machine without oil.
Check the condition of the grinding pins regularly.
Store the grinder where it is out of the reach of children.
Securely fasten the workpiece you want to grind.
Use only organically bonded grinding wheels and organically or inorganically bonded grinding pins and small grinding wheels (wheel Ø smaller than 20 mm).
Under no circumstances are you to use grinding wheels at speeds higher than the speed quoted in min-1 by the wheel’s manufacturer.
Allow new grinding wheels a running-in period of 30 seconds on the tool. Operators and other personnel are to stay out of the danger zone during the trial run. Hold the rotating grinding pin away from the body.
Never halt a grinding wheel by pressing on its circumference or face.
Tighten the lock nut only enough to hold the grinding wheel securely in place.
Operators are to be thoroughly instructed on how to use the grinding tool safely.
Always examine the grinding pins for signs of damage before you start to work.
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, particularly after a long period of use.
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.
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.

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. Insert adapter sleeve size Ø 3 or Ø 6 mm depending on which grinding pin you want to use. To do so, unscrew the lock nut, insert the adapter sleeve and re-tighten the lock nut by hand. Then insert the correct grinding pin (make sure it has the correct shaft diameter!) and tighten the lock nut with the two chuck keys, using the one key to hold the adapter sleeve mount.

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 pin grinder. Use only special tool oil for this purpose.
You can choose from the following options for lubricating the tool:

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

By hand
Each time before you use your pin 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.
