DO NOT FORCE, LET THE SAW DO THE WORK. Move the machine
forward only rapidly enough to keep the blade cutting.
You will find that the open throat and clear forward edge of the saw
base make it easy to follow the line and cut closely to the pattern. You
need not cut oversize for hand finishing or sanding on most
materials. The smoothness of cut will often make further sanding
unnecessary.
MAINTENANCE
KEEP TOOL CLEAN
Periodically blow out all air passages with compressed air. Remove
build up of grime resulting from working green or sappy wood. All
plastic parts should be cleaned with soft cloths. NEVER use solvents
when cleaning plastic parts.
CAUTION: Wear safety glasses when 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
Your machine is lubricated at the factory with sufficient lubricant to
last for approximately one year's operation time. To add lubricant it is
necessary to dismantle the tool. This operation should always be
handled by the nearest Porter-Cable Authorized Service Center. All
repairs and servicing made by these centers are fully guaranteed
against defective materials and workmanship.
BRUSH INSPECTION
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; worn parts replaced, when necessary;
relubricated with fresh lubricant, if required; reassembled with new
brushes; and performance tested.
Any loss of power before the above maintenance check may indicate
the need for immediate 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 immedi¬
ate service.
SERVICE AND REPAIRS
All quality tools will eventually require servicing or replacement of
parts due to wear from normal use. These operations, including
brush inspection and replacement, should ONLY be performed by
either an AUTHORIZED PORTER-CABLE SERVICE STATION or a
PORTER-CABLE SERVICE CENTER. All repairs made by these
agencies are fully guaranteed against defective material and work¬
manship. We can not guarantee repairs made or attempted by
anyone other than these agencies.
