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. Adjusting a loose slide pipe

Slide Pipe (A)

Holder (A)

After extended use of the power tool, the slide pipe (A) and the bushing can become loose due to vibration. Never operate the tool if any components are loose to avoid personal injury.

(1)Loosen the 8mm nut and tighten the four 8mm hexagon socket set screws until the power tool operates smoothly without looseness.

(2)Properly tighten the 8mm nut after completing these adjustment.

3. Inspecting the carbon brushes (Fig. 43 and Fig. 44)

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. 43.

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. 44) with a slotted (minus) screwdriver.

4. 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.

5. Inspecting the safety cover for proper operation

Before each use of the tool, test the safety cover (see Fig. 7) to assure that it is in good condition and that it moves smoothly.

Never use the tool unless the safety cover operates properly and it is in good mechanical condition.
