POLISHING TIPS

USE ONLY QUALITY POLISH MADE FOR POWER POLISHING APPLICATION and apply per manufacturer’s instructions.

For best results, thoroughly clean surface to be polished.

When polishing automobiles, wash the car thoroughly to remove dust, dirt and other abrasives that may scratch the finish.

Buffs or pads may become gummed up after a period of use. They may be washed out with soap and water. Shake out as much water as possible and then spin dry on machine. Do this in an area where you will not splatter articles.

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.

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.
