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.
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 SERVICE

Authorized Porter-Cable Service Station to be thoroughly cleaned and
