MAINTENANCE
Before making any adjustments or changing accessories, turn off the tool and disconnect it from its
power source.
1. The brushes should be checked periodically and worn-out brushes should be replaced. After
replacing, inspect whether the new brushes can move freely in the brush holder. Run the motor
for 15 minutes without load to shape the brushes, so that they are properly aligned with
the commutator.
2. Keep the vent passage clear from dirt. Clean off the accumulated dust and oil dirt periodically.
3. During normal operation, if anything happens, the power supply should be cut off at once and
the tool should be checked and repaired.
4. Clean the tool after each use.
5. Check for damaged parts. Before using any tool, any part that appears to be damaged should
be carefully checked to determine that it would operate properly and perform its intended
functions. Check for alignment and binding of moving parts, for broken parts or mounting
fixtures, or for any other condition that may affect proper operation. Any part that is damaged
should be repaired or replaced by a qualified technician.
6. When servicing, use only identical replacement parts. Only use accessories intended for use
with this tool. Replace damaged parts immediately.
7. Keep the tool clean. Wipe the tool with a clean cloth and periodically blow out all areas with
compressed air. If compressed air is not available, use a brush to remove dust from all areas.
Do not use harsh chemicals or solvents to clean the tool. These chemicals could seriously
damage the plastic housing.
8. Regularly inspect all mounting screws to ensure tightness. Should any screws become loose,
tighten immediately.
9. If repairs are required, bring your tool to an authorized service centre.
CAUTION! Do not at any time allow brake fluids, gasoline, petroleum-based products, penetrating
oils, etc. to come in contact with plastic parts. They contain chemicals that can damage, weaken or
destroy plastic.
WARNING! To avoid fire or toxic reaction, never use gasoline, naphtha, acetone, lacquer thinner or
similar highly volatile solvents to clean the tool.
REPLACING CARBON BRUSHES
1. Using the parts list included, locate the carbon brushes. Remove the brush holder caps with a
screwdriver and inspect the carbon brushes. Replace them when they are worn up to about
one third.
2. Take the old brushes out and install the new brushes. Remove all of the brushes at the same
time. Make sure the brush slides freely within the brush housing.
3. Run the motor for 15 minutes without load to shape the brushes, so that they are properly
aligned with the commutator.
