9. MAINTENANCE AND INSPECTION

WARNING: To avoid an accident or personal injury, always confirm that the switch is turned OFF and

that the power plug has been disconnected from the receptacle before performing any

maintenance or inspection of this tool.

9-1. 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.

9-2. Inspecting the Carbon Brushes (Fig. 23 and Fig. 24)

The carbon brushes in the motor are expendable parts. If the brushes become excessively worn, motor trouble

might occur. Therefore, inspect the brushes periodically and replace them. Check the brushes after the first 50

hours of use for a new machine or after a new set of brushes have been installed. After the first check, examine

them after about every 10 hours of use until such time that replacement is necessary. When the carbon on either

brush is worn to 5 mm (3/16") in length or if either spring or shunt wire is burned or damaged in any way, replace

both brushes (see Fig. 23). If the brushes are found to be serviceable after removing, reinstall them in the same

position as before. 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. 24) with a flatblade

screwdriver.

9-3. 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.
