22 10-Inch Compound Miter Saw Operator's Manual
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. 28 and Fig. 29):
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. 28. 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. 29) with a slotted (minus) screwdriver.

3. Inspecting the mounting screws:
Regularly inspect each component of the power tool for looseness. Retighten mounting screws on any loose
part.
WARNING: TO PREVENT PERSONAL INJURY, NEVER OPERATE THE POWER TOOL IF ANY
COMPONENTS ARE LOOSE.
4. Inspecting the safety cover for proper operation:
Before each use of the tool, test the safety cover (see Fig. 5) to assure that they are in good condition and that
they move smoothly. Never use the tool unless the safety cover operates properly and unless they are in good
mechanical condition.
