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.

CAUTION: 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.

FRAME PROTECTOR

The frame protector bar is made of hardened steel. It is located, to the left and at the rear of the idler pulley and is fastened to the frame. This bar protects the frame of the machine when tracking the abrasive belt. Always adjust the belt so it moves evenly across (without rubbing) the protective bar. When this bar becomes worn and uneven, replace it with a new one (available from your Porter-Cable Service Center).

DRIVE PULLEY

The rubber-covered drive pulley at the rear of the machine is crowned or tapered from the center to either side to make the abrasive belt run true and in line with the idler pulley at the front of the machine. After considerable use, the crown will wear away and the belt will begin to run off the side of the pulley and cut into the guide block or frame. When the crown is worn to this extent, have the drive pulley replaced by your Authorized Porter-Cable Service Station. This action can be checked each time the abrasive belt is replaced and tracked. After the belt is tracked to the front pulley, watch it for a few seconds to see that it runs true and stays in place on the back pulley. Avoid getting oil and grease on the rubber cover. It will cause it to fail.

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.

At approximately 100 hours of use, take or send your tool to your nearest authorized Porter-Cable Service Station to be thoroughly cleaned and inspected. Have worn parts replaced and lubricate with fresh lubricant. Have new brushes installed, and test the tool for performance.
