trigger switch is released. If the trigger switch remains
depressed, the worklight will remain on.
nOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as a flashlight.
Variable Speed Trigger Switch (Fig. E)
Lock Button and Trigger switch
Your saw is equipped with a lock button 
To lock the trigger switch, press the lock button as shown
in Figure E. Always lock the trigger switch 
or storing the tool to eliminate unintentional starting. To lock
the tool, slide lock button to the locked position. When in
the locked position, the tool is locked and the trigger switch
cannot be pulled.
To unlock the trigger switch, press the lock button as
shown in Figure E. Pull the trigger switch to turn the motor
ON. Releasing the trigger switch turns the motor OFF.

WARNING: This tool has no provision to lock the
switch in the ON position, and should never be locked
ON by any other means.
The variable speed trigger switch will give you added
versatility. The further the trigger is depressed the higher the
speed of the saw.

CAUTION: Use of very slow speed is recommended
only for beginning a cut. Prolonged use at very slow
speed may damage your saw.
Cutting (Fig. A, B, D–G)
The blade 
 10 
should extend past the pivoting shoe 
the thickness of the workpiece throughout the cut. Select
the blade best suitable for the material to be cut and use the
shortest blade suitable for the thickness of the material.
nOTE: Do not use jigsaw blades with this tool.
nOTE: Before cutting any type of material, be sure it is firmly
anchored or clamped to prevent slipping.
Place blade 
 10 
and pivoting shoe 
to be cut.
Switch on saw motor and allow it to obtain maximum
speed before applying pressure.
Always hold saw firmly with both hands while cutting as
shown in Fig. D. Whenever possible, the pivoting shoe
must be held firmly against the material being cut. This
will prevent the saw from jumping or vibrating and will
minimize blade breakage.
Wood Cutting (Fig. A, B, F)
1. Before cutting any type of wood, be sure the workpiece
is firmly anchored or clamped to prevent slipping.
2. Place blade 
 10 
 and pivoting shoe 
to be cut.
3. Switch on saw motor before starting the cut.
4. Always hold saw firmly with both hands while cutting.
Whenever possible, the pivoting shoe must be held
firmly against the material being cut. This will prevent
the saw from jumping or vibrating and minimize
blade breakage.

Metal Cutting (Fig. G)
1. Use a finer blade for ferrous metals and a coarse blade for
non‑ferrous materials.
2. In thin gauge sheet metals it is best to clamp wood to
the underside of the sheet. This will ensure a clean cut
without excess vibration or tearing of metal.
3. Avoid forcing cutting blade as this reduces blade life and
causes costly blade breakage.
nOTE: You should spread a thin film of oil or other coolant
along the line ahead of the saw cut for easier operation
and longer blade life. For cutting aluminum, kerosene
is preferred.
Plunge Cutting (Fig. A, B, H)
Measure the surface area to be cut and mark clearly with a
pencil, chalk or scriber.
1. Insert blade 
 10 
 in blade clamp collar.
2. Tip the saw backward until the back edge of the pivoting
shoe is firmly on the work surface.
3. Switch motor on, permitting blade to attain
maximum speed.
4. Grip handle steadily and begin a slow, deliberate upward
swing with the handle of the saw.
5. The blade will begin to feed into material. Always be sure
blade is completely through material before continuing
with plunge cut.
nOTE: In areas where blade visibility is limited, use the edge
of the pivoting shoe as a guide.
Project Tips
Cut only with sharp blades; they cut cleaner, faster and put
less strain on the tool while cutting.
When cutting, always ensure that the pivoting shoe is
resting against the workpiece. This will improve operator
control and minimize vibration.
For longer blade life, use bi‑metal blades or carbide
tipped blades. These utilize a carbon steel back welded
to high speed steel teeth making the blade more flexible
and less prone to breaking.

MAINTENANCE


WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can cause injury.
Your PORTER‑CABLE power tool has been designed to
operate over a long period of time with a minimum of
maintenance. Continuous satisfactory operation depends
upon proper tool care and regular cleaning.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this procedure.
