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:
2. Inspecting the lever
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).

* Confirm that the spindle lock has returned to the retract position after installing or
removing the saw blade.
* Tighten the 10mm bolt so it does not come loose during operation.
Confirm the 10mm bolt has been properly tightened before the power tool is started.
Never attempt to install saw blades larger than 12" (305mm) in diameter.
Always install saw blades that are 12" (305mm) in diameter or less.
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.
