the left by 17 mm box wrench as indicated in Fig. 24-b.
CAUTION: * Confirm that the spindle lock has returned to the retract position after installing or
removing the saw blade.
* Tighten the bolt (A) so it does not come loose during operation.
Confirm the bolt (A) has been properly tightened before the power tool is started.
2. Dismounting the saw blade
Dismount the saw blade by reversing the mounting procedures described in paragraph 1 above.
The saw blade can easily be removed after lifting the safety cover.
CAUTION: Never attempt to install saw blades larger than 15" (380 mm) in diameter.
Always install saw blades that are 15" (380 mm) in diameter or less.
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.

3. Inspecting the mounting screws
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.
