6. INSPECTION AND REPLACEMENT OF CARBON BRUSHES
CAUTION
:
Unplug the tool before checking the carbon brushes.
The life of carbon brushes varies. It depends on the workload
that is demanded of the motor. Check the carbon brushes after
the first 50 hours of use in the case of a new tool or after
installing a new set of carbon brushes.
After the first check, they must be inspected after every
10 hours of use until it becomes necessary
to replace them.
The carbon brushes doors (see figure opposite) are located on
each side of the motor housing. Replace the two carbon
brushes when the carbon of a carbon brush is used, and in less
than 5 mm in length, or if a spring or wire is burned or
damaged. If the carbon brushes are still usable after
inspection, return them to the position they were in
originally.
To do this, follow these steps:
1. Loosen and remove the two truss heads screws (B) Fig.26
that hold the cover of the motor casing(A).
2. Once the motor casing is removed,
remove each carbon brush(B) Fig.27. Check them and replace if
necessary. Replace the two carbon brushes even if only one
of the two is worn down.
3. To remove the carbon brushes, lower the spring(A), unplug
the carbon brush's wire(C) then remove the carbon brush and
check it. Repeat this step for the other carbon brush.
4. Replace the carbon brushes as soon as the wear limit is
reached (see Fig.28). Keep them clean.
NOTE: After checking the carbon brushes, make sure to
put them back in the same position that they were in at the
outset if you do not replace them.
5. Place the carbon brushes in the motor casing. Reconnect
the wires to the terminals, attach the carbon brushes by
readjusting the springs(A) then put the motor cover back in
place and tighten the two screws(B) Fig.26.
6. Start the saw and let it run for about 5 to 10 minutes to
allow the carbon brushes to position themselves
correctly. If the carbon brushes are not correctly mounted, the
circuit breaker cannot function normally and the engine
may suffer damage. When the carbon brushes are being
"positioning", you can see some sparks in the motor. This is quite normal for new carbon brushes.
Warning: Always follow the basic safety precautions when using power tools in order to reduce the risk of fire, electric shock
and injury. In addition, you must read all instructions before using this product and save these instructions so you can refer
to them at any time.
