MAINTENANCE AND INSPECTION

WARNING:
To avoid an accident or personal injury, always confirm 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.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the first sign of deterioration or damage.
A damaged saw blade can cause personal injury and a worn saw blade can cause ineffective operation
and possible overload to the motor.
CAUTION:
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.
2. Inspecting the carbon brushes (Fig. 26, 27)
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. 26.
Also, keep the carbon brushes clean so that they will slide smoothly within the brush holders.
The carbon brushes can easily be removed after removal of the brush caps (see Fig. 27) with a slotted
(minus) screwdriver.
1/4" (6 mm)
5/8" (16 mm)

Regularly inspect each component of the power tool for looseness.
Re-tighten mounting screws on any loose part.
WARNING:
To prevent personal injury, never operate the power tool if any components are loose.
(4) Thoroughly clean washer (B) and the bolt (A), and install them
onto the saw blade spindle.
