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.
WEAR ANSI Z87.1 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
FACTORY SERVICE CENTER.
MAINTENANCE
Use the lever (A) Fig. 14, provided on the
telescoping guard when you have to retract the telescoping guard
manually.
POCKET CUTS (PLUNGE CUTTING)
A pocket cut is one which must be made inside the area of the material and
not starting from the edge. Mark the area clearly with lines on all sides. Start
near the corner of one side and place front edge of saw base firmly on the
work. Hold saw up so blade clears the material. Be sure you have adjusted
the blade properly for depth of cut. Push the telescoping guard lever all the
way back so the blade is
exposed as shown in Fig.
17. Start the motor and
lower the blade into the
work. After the blade has
cut through, and the base
rests flat on the work,
follow the line right up to
the corner. Use a keyhole
or bayonet saw to cut the
corners out clean.
