glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS wear certified

CLEANING
Periodically blowing dust and chips out of the motor housing using clean, dry
compressed air is a suggested maintenance procedure. To reduce the risk of serious per-
sonal injury, ALWAYS wear ANSI Z87.1 safety glasses while using compressed air.
When cleaning, use only mild soap and a damp cloth on plastic parts. Many
household cleaners contain chemicals which could seriously damage plastic. Also, do
not use gasoline, turpentine, lacquer, paint thinner, dry cleaning fluids or similar products
which may seriously damage plastic parts. NEVER let any liquid get inside the tool; NEVER
immerse any part of the tool into a liquid.
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
For your continued safety and electrical protection, brush inspection and replacement on
this tool should ONLY be performed by a PORTER-CABLE FACTORY SERVICE CENTER
OR PORTER-CABLE AUTHORIZED WARRANTY SERVICE CENTER.
At approximately 100 hours of use, take or send your tool to your nearest Porter-Cable
Factory Service center or Porter-Cable Authorized Warranty Service Center to be thoroughly
cleaned and inspected. Have worn parts replaced and lubricated with fresh lubricant. Have
new brushes installed, and test the tool for performance.
Any loss of power before the above maintenance check may indicate the need for imme-
diate servicing of your tool. DO NOT CONTINUE TO OPERATE TOOL UNDER THIS
CONDITION. If proper operating voltage is present, return your tool to the service station for
