DO NOT FORCE, LET THE SAW DO THE WORK. Move saw forward only
fast enough to keep blade cutting. If cutting becomes difficult, the blade is
dull and should be changed at once. A dull blade not only makes cutting
more difficult but also overburdens the motor. You will find the open throat
and clear forward edge of the saw base make it easy to follow the line.
LUBRICATION
Although all Porter-Cable tools have been thoroughly lubricated with a
sufficient amount of high grade lubricant at the time of manufacture, it is
recommended that the oil level in the gear chamber be checked before
using your saw and periodically thereafter as follows:
DISCONNECT TOOL FROM POWER SOURCE.
1. Remove saw blade and set machine on a level surface.
2. Remove oil plug from front of machine.
3. Gear lubricant should be level with the bottom of the oil plug hole, but
should not run out. If this condition does not exist, tip machine up and
add a small amount of Porter-Cable lubricant until it is even with the
bottom of the hole.
4. NOTE: DO NOT OVERFILL. If you do, the pressure created by the
pumping action of the gears may force lubricant through seals and into
motor and mechanism chamber causing damage to the machine.
5. To change lubricant in the mechanism housing it is necessary to
dismantle the tool. This operation should only be performed by a
AUTHORIZED PORTER-CABLE SERVICE STATION or a PORTER-
CABLE•DELTA FACTORY SERVICE CENTER.
However, the lubricant may be checked as follows:
A. Remove all traces of the sawdust and grime from around the gear
housing and blade holder to eliminate the possibility of
contaminating the mechanism lubricant.
B. Remove four gear housing cover screws located around the knob
on the left side of the machine.
C. Lift off cover and gasket being careful not to damage the gasket.
D. There should be a thin layer of lubricant around the blade holder. If
this lubricant is contaminated, take your saw to an authorized
Porter-Cable Service Station for a thorough cleaning and lubrication.
If lubricant is needed, brush a thin coat of Porter-Cable lubricant on
the blade holder. NOTE: An excessive amount of lubricant may leak
through the blade holder dust seal and spatter on material being
cut.
E. Replace gasket and gear housing cover and tighten four screws
securely.
