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.
WARNING: Never use solvents or other harsh
chemicals for cleaning the non‑metallic parts of the
tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with
water and mild soap. Never let any liquid get inside the
tool; never immerse any part of the tool into aliquid.
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 CRAFTSMAN 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.
Pocket Cutting - Wood Only (Fig. K)
Measure the surface area to be cut and mark clearly with a
pencil, chalk orscriber.
1. Insert blade
in blade clamp collar
and tighten
blade clampsecurely.
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
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 pocket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 motor 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.
Cutting (Fig. A, G–K)
The blade
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
and pivoting shoe
lightly against work
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. G. 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. G, I)
1. Before cutting any type of wood, be sure the workpiece
is firmly anchored or clamped to preventslipping.
2. Place blade
and pivoting shoe
firmly against work
3. Switch on saw motor before starting thecut.
4. Always hold saw firmly as shown in Fig. G 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
Metal Cutting (Fig. J)
1. Use a finer blade for ferrous metals and a coarse blade for
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
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H. 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.
