OPERATION

USING A DISC GRINDER

Be certain that the wheel guard and auxiliary handle are installed.

Firmly grip the auxiliary handle and motor housing (Fig. 8). Lift up the rear of the motor housing so that only the front section of the grinding wheel contacts the work. Use light pressure. Always lift the grinder off the work before starting or stopping the motor. The arrow on the front gear housing indicates the direction in which the grinding wheel rotates.

MAINTENANCE

KEEP TOOL CLEAN

Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

Wear safety glasses while using compressed air.

FAILURE TO START

Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line.

LUBRICATION

This tool has been lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. No further lubrication is necessary.

BRUSH INSPECTION AND LUBRICATION

For your continued safety and electrical protection, brush inspection and replacement on this tool should ONLY be performed by an AUTHORIZED PORTER-CABLE SERVICE STATION or a PORTER-CABLE·DELTA FACTORY SERVICE CENTER.
