Kompernass PWS 1100 - Manual (Page 6)

SETTING THE SPEED
You can set the required speed / rpm using the speed control wheel ባ to suit your work.
You can also change the speed whilst you are working. A practical test before you start can help you to determine the most appropriate
speed to use.
To increase the speed (rotation), turn the speed control wheel ባ towards 6 (6 = highest speed).
To decrease the speed (rotation), turn the speed control wheel ባ towards 1 (1 = lowest speed).
CHANGING THE GRINDING DISC
Note: Only use discs that are free of contaminants, as indicated in "Important safety advice".
Isolate the tool from the electrical power supply by pulling the plug from the socket.
Press the spindle lock
ብ to block the drive. Remove the clamping nut ቨ using the wrench.
Once the grinding disc has been changed retighten the clamping nut ቨ .
Warning: If after replacement, the grinding disc runs erratically or vibrates, it must be changed immediately.
AUXILIARY HANDLE
Warning: For your safety, only use the grinder with the auxiliary handle ቤ fitted.
The auxiliary handle ቤ can be fitted to the left or right hand side of the grinding head to suit your way of working.
MAINTENANCE OF THE ANGLE GRINDER
1. Clean the angle grinder regularly. For the best results do this straight after the work has been completed.
2. Do not allow liquids to get inside the grinder. Use a soft cloth for cleaning the housing. Do not use petrol, solvents or cleaners
that might attack the plastic.
3. Air vents must always be clear and clean.
4. The replacement carbon brushes supplied may only be changed and fitted at an authorised repair centre (both brushes must be changed
at the same time).
ADVICE ON WORKING METHODS, TIPS AND TRICKS
• If the weight of the workpiece is insufficient to keep it absolutely still during grinding, then fasten it securely.
• Do not press on with the grinder so much that you bring it to a standstill.
• For the best grinding performance move the grinder evenly backwards and forwards over the workpiece at an angle of 15° to 30° (angle
between the grinding disc and workpiece).
• When working on inclined surfaces, do not press the grinder on to the workpiece with too much force. If the speed drastically reduces,
do not press on as hard and that will ensure you work safely and effectively. If the grinder is brought to a sudden halt or jams, switch off
the power immediately.
• Only use cutting and grinding discs that have been MPA certified. Never use cutting discs for roughing.
• Cutting: Work with moderate force and do not use the cutting disc
1 at an angle. For profiled sections and rectangular hollow sections
you will find it best to cut where the cross section is the smallest.
