MAINTENANCE AND INSPECTION

WARNING
To avoid an accident or personal injury, always
confirm the trigger switch is turned OFF and that 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 (Fig. 26 and Fig. 27)
If the M8 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).
