2. Mounting the saw blade
Thoroughly remove dust from the wheel washer and bolt then mount the saw blade wheel by following
the dismounting procedures in reverse order.
WARNING: When mounting the saw blade confirm that the rotation indicator mark on the saw
blade and the rotation direction of the saw cover.
CAUTION: Confirm that the spindle lock has returned to the retract position after installing or
removing the saw blade
Tighten the bolt so it does not come loose during operation.
Confirm the bolt been properly tightened before the power tool is started.
Never attempt to install saw blades larger than 14" (355 mm) in diameter.

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. 20 and Fig. 21)
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. 20.
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. 21) with a slotted
(minus) screwdriver.
