MAINTENANCE AND INSPECTION

WARNING:
1. Inspecting the saw blade
Always replace the saw blade immediately upon the fi rst sign of deterioration or damage.
A damaged saw blade can cause personal injury and a worn saw blade can cause ineff ective
operation and possible overload to the motor.
CAUTION:
2. Inspecting the carbon brushes (Fig. 45 and Fig. 46)
The carbon brushes in the motor are expendable parts.
If the carbon brushes become excessively worn, motor trouble might occur.
Therefore, inspect the carbon brushes periodically and replace them when they have
become worn to the wear limit line as shown in Fig. 45.
Also, keep the carbon brushes clean so that they will slide smoothly within the brush
holders.
Remove the two securing screws and the motor rear cover from the motor. Carefully remove
the brush cap on the side of the motor. Third, pull out the carbon brush and replace. The
ears on the metal end of the assembly go in the same hole the carbon part fi ts into. Last,
tighten the cap snugly, but do not overtighten. Repeat above procedure for the carbon
brush located on the other side of the motor.
Never attempt to install saw blades larger than 10" (255 mm) in
diameter.
Always install saw blades that are 10" (255 mm) in diameter or
less.
To avoid an accident or personal injury, always confi rm that
the trigger switch is turned OFF and the power plug has been
disconnected from the receptacle before performing any
maintenance or inspection of this tool.
Never use a dull saw blade. When a saw blade is dull, its resistance
to the hand pressure applied by the tool handle tends to increase,
making it unsafe to operate the power tool.
