MAINTENANCE

Every 50 hours of operation blow compressed air through the motor while running at no load to clean out
accumulated dust.
Always check for a damaged power supply cable, check for loose fasteners and always keep alert for
unusual noises and vibration when operating.
WARNING: Never operate a damaged machine. Always tag a damaged machine and take it out of
service until repairs can be made.
Maintenance which should be performed by an authorized service center, include the following:
• Replace water seals as needed.
• Replace the carbon brushes as needed
• Replace the clutch discs and spring as needed.
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and must be replaced when they reach their wear limit. This
machine is equipped with auto-stop carbon brushes. If the machine comes to a stop unexpectedly, the brushes
should be checked. The auto-stop brush design protects the motor by stopping the machine before the carbon
brushes are completely worn out.
Caution: Always replace the brushes as a pair.
To replace:
1. Remove the 12 screws to open up the handle halves. Carefully move the parts to one side, taking care not
to strain the wiring.
2.
Using pliers rotate the brush spring out of the way and slide the old carbon brush out of the brush
holder.
3.
Unscrew the screw to remove the brush lead. The old carbon brush may now be lifted away.
4.
Install a new brush. Installation is the reverse of removal.
5. Replace the motor tail cover.
If the replacement of the power supply cord is necessary, this has to be done by the manufacturer or
their agent in order to avoid a safety hazard.
WARNING: All repairs must be entrusted to an authorized service center. Incorrectly performed repairs
could lead to injury or death.
