MAINTENANCE
MAINTENANCE
All the ball bearings are sealed and lubricated for life and will require no
maintenance.
Cleaning
• After use, wipe off chips and dust adhering to the tool with cloth or the like. Keep
the blade guards and covers clean. Lubricate moving parts with machine oil to
prevent rust.
To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or
adjustments should be performed by your nearest authorized service center.
REPLACING CARBON BRUSHES
Remove and check the carbon brushes regularly (normally after 50 hours of use).
The carbon brushes are installed inside the motor housing. Using a screwdriver,
remove the 2 pan head screws (A) Fig.16 that hold the motor housing cap (B) in
place.
Once the motor housing cap is removed, disconnect the carbon brush wire (A)
Fig.17 from the terminal. To release the carbon brush from the holder, lower the
retaining spring (B) using a small screwdriver.
Remove the carbon brushes (C) Fig.17 from the motor housing and inspect them.
Carbon brushes need to be replaced once they wear down to their limit mark, see
Fig.18. Keep the carbon brushes clean and free to slip in the holders.
If they have worn down to the limit mark, purchase a set of identical replacement
carbon brushes (both carbon brushes should be replaced at the same time). Insert
new carbon brushes into the holders, connect them to the terminals, reposition the
retaining springs and reinstall the motor housing cap using the 2 pan head screws.
