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 lever
If the M6 hexagonal head bolts (2) are loose, align the sides of the
fence and saw blade with the steel square. After adjusting the saw
blade and fence to a ninety-degree angle, tighten the lever securing
hexagonal head bolts (2).

3. Inspecting the carbon brushes (Fig. 35 and Fig. 36)
The carbon brushes in the motor are expendable parts.
If the carbon brushes become excessively worn, motor trouble might
occur.
