much. It may be necessary to cool the material by immersing it
in coolant or water. Do not cool the grinding wheel with coolant
or water. As the grinding wheel wears out readjust the workrest
so the distance between its edge and the wheel is not greater
than 1.5 mm. Ensure the object to be processed does not fall
out of your hands and does not jam between the workrest and
the wheel. It may cause the grinding wheel to crack or personal
injuries.

OPERATION AND MAINTENANCE

Always switch off the grinder with switch button and unplug
the power cord from the mains socket before commencing any
activities related to adjustment or maintenance.
GRINDING WHEEL CLEANING
Cleaning a grinding wheel also levels front surface. It improves
working efficiency and prevents vibrations.
• Take wheel dresser (fig. F).
• Press the wheel dresser on the workrest (8), at approximately 5 mm
distance from grinding wheel.
• Start the motor and allow it to reach its maximum speed.
• Hold the wheel dresser the way it is shown on fig. F.
• Slowly move the dresser towards the wheel and slide it across the
wheel width as many times as it is necessary to flatten the wheel
surface.
• Adjust the workrest (8) so it is positioned at a distance of 1 – 1.5 mm
from the wheel surface.
Do not allow the wheel dresser to touch the grinding wheel
before reaching top rotational speed, because it can kick back,
be torn out of hand and cause serious body injury. Do not press
the wheel dresser harder to flatten the wheel surface with one
passage only.
BRUSHING OR GRINDING WHEEL REPLACEMENT
Check the grinding wheel or brush before replacement, do not
use brushes and wheels with dents, cracks, excessively worn or
otherwise damaged.
Disconnect the power tool from power supply.
Ensure that new grinding wheel or brush is characterized by maximal
rotational speed equal to 2950 rpm or more. Notice that the nut of
the left grinding wheel is left-hand threaded and it must be turned
clockwise to unscrew. Nut of the right grinding wheel is right-hand
threaded and it must be turned counter-clockwise to unscrew.
• Unscrew fixing screws and remove appropriate disc cover (4) (fig. G).
• Hold the wheel or brush firmly (wear protective gloves to protect
your hands).
• Unscrew the nut that fixes the grinding wheel and the outer flange
(fig. H and I).
• Remove worn out or damaged brushing or grinding wheel (fig. K).
• Install new grinding wheel or brush onto the shaft and ensure that
there is a washer between the wheel and flange on each side, and
that the wheel or brush is slide fitted, not clearance fitted.
• Screw the nut that fixes the wheel back on its place.
• Hold brushing or grinding wheels when tightening the nuts.
• Be careful not to damage the shaft thread due to applying excessive
torque.
• Install wheel cover (4) and fix it with screws.
• Adjust setting of the workrest and eye shield.
• Turn the wheel by hand to ensure it is free to rotate.
• Connect the grinder to mains socket, stand aside, switch on the
grinder and allow it to work at full speed for few minutes.
CLEANING
Never use any caustic agents, or cleaning agents based on petrol
or alcohol. Protect the grinder against moisture.
• Keep outer surfaces of the grinder clean, remove dust from places
where the dirt accumulates with brush or compressed air.
• Wipe shields and body with damp, soft cloth. You can also use
delicate detergent.
• Wipe eye shields with damp soft cloth, be careful not to scratch
them. You can also use delicate detergent.
All faults should be repaired by service workshop authorized by the
manufacturer.
