MAINTENANCE

EXTENSION CORDS

The use of any extension cord will cause some loss of power. To keep the loss to a minimum and to prevent tool overheat- ing, use an extension cord that is heavy enough to carry the current the tool will draw.

A wire gage size (A.W.G.) of at least 14 is recommended for an extension cord 25 feet or less in length. When working outdoors, use an extension cord that is suitable for outdoor use. The cord's jacket will be marked WA.

WARNING:

Keep extension cords away from the cutting area and position the cord so that it will not get caught on lumber, tools, etc., during cutting operation. Failure to heed this warning may result in serious personal injury.

CAUTION:

Check extension cords before each use. If dam- aged, replace immediately. Never use tool with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury.

BRUSH REPLACEMENT

See Figure 40.

The saw has externally accessible brush assemblies that should be periodically checked for wear.

Proceed as follows when replacement is required:

nUnplug the saw.

WARNING:

Failure to unplug the saw could result in accidental starting causing serious injury.

nRemove brush cap with a screwdriver. Brush assembly is spring loaded and will pop out when you remove brush cap.

nRemove brush assembly.

nCheck for wear. Replace both brushes when either has less than 1/4 in. length of carbon remaining. Do not re- place one side without replacing the other.

nReassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube.

nMake sure brush cap is oriented correctly (straight) and replace.

nTighten brush cap securely. Do not overtighten.

WARNING:

Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.

WARNING:

To ensure safety and reliability, all repairs should be performed by a qualified service technician at a Authorized Service Center to avoid risk of personal injury.
