Drive Sprocket
Running a good chain on a worn out sprocket will prematurely wear out its drive links. After about 3
chains, the drive sprocket will wear away and need replacement.
CHANGING THE DRIVE SPROCKET
To change the drive sprocket, first remove the side cover, chain, and guide bar. Using circlip pliers, remove the
circlip, then the washer which retain the drive sprocket, then lift the sprocket off the splines. Replacement is
the reverse of removal.
MAINTENANCE
This machine operates in a harsh environment with water and slurry. At the end of each work day, thoroughly
clean the machine with water, then oil the bar and chain with a water displacing spray such as WD-40 to
prevent rust. Ensure that the water feed ports are clear. Chain tension should be checked frequently and
readjusted immediately when necessary. Inspect all parts of the saw for proper function before each use. Pay
special attention to the condition of the chain, inspecting each diamond segment for wear or damage.
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 brush holders. 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 screw and remove the brush cover.
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 brush cover.
WARNING: If the replacement of the power supply cord is necessary, this has to be done by the

WARNING: All repairs must be entrusted to an authorized service center. Incorrectly performed repairs
