OPERATION
WARNING:
Battery products are always in operating condition.
Therefore, the switch should always be locked when not
in use or carrying at your side.
SELECTING BLADES
Selecting the correct type of blade is important in order to
obtain the best performance from the saw. Select the blade
based on the application and on the material you wish to
cut. Selecting the right blade will give you a smoother, faster
cut and prolong the life of the blade.
Blades with fewer teeth, 10 teeth per inch (TPI) are typically
used for cutting wood, while blades with more teeth are
better for cutting metal or plastic. We recommend 14 TPI for
plastics and soft metals and 18 TPI for hard metals.
INSTALLING/REMOVING BLADE
See Figure 2, page 9.
To install the blade:
 Remove the battery pack.
 Lift the blade clamp lever located on the side of the saw.
 Insert the saw blade into the blade clamp opening.
 Release the blade clamp lever to lock the blade into place.
To remove the blade:
 Remove the battery pack.
 Lift the release lever to release the blade from the blade
clamp.
TURNING THE SAW ON/OFF
See Figure 3, page 10.
The lock-off button, located on the handle above the switch
trigger, reduces the possibility of accidental starting.
 To turn the saw on: Slide lock-off button to the unlocked
position, and press the switch trigger.
 To turn the saw off: Release the switch trigger.
CAUTION:
The lock-off button should be in the locked position when
the saw is not in use or is being transported.
GENERAL CUTTING
See Figure 4, page 10.
WARNING:
Make sure the blade does not touch work until motor
reaches full speed, since this could cause loss of control
resulting in serious injury.
 Secure the workpiece to a work bench or table with a
vise or with clamps.
 Mark the line of cut clearly.
 Make sure the saw blade teeth are clean of any debris or
foreign material.
 Hold the saw firmly in front of and clearly away from you.
 Slide the lock-off button to the unlocked position and
depress the switch trigger.
 Allow the saw blade to reach full cutting speed.
 Set the shoe assembly against the workpiece.
 Move the blade into the workpiece.
NOTE: Do not force. Use only enough pressure to keep
the saw cutting. Let the blade and saw do the work. Keep
pressure on the shoe, against the workpiece.
PLUNGE CUTTING
See Figure 5, page 10.
WARNING:
Make sure the blade does not touch work until motor
reaches full speed, since this could cause loss of control
resulting in serious injury.
WARNING:
Blades longer than 6 in. can whip and should not be used
for plunge cutting. Failure to heed this warning can result
in serious personal injury.
 Choose a convenient starting point inside the cutting area
and place the tip of the blade over that point.
 Rest the front edge of the shoe assembly on the workpiece
and hold it firmly in position during the cut.
 Slide the lock-off button to the unlocked position and
depress the switch trigger.
 Allow the saw blade to reach full cutting speed.
 Tilt the saw downward until the tip of the blade starts
cutting the workpiece.
 Allow the blade to penetrate the workpiece.
 Tilt the saw until the blade is perpendicular to the
workpiece.
WARNING:
Cutting into electrical wiring can cause the blade, the
blade clamp, and the saw bar assembly to become elec-
trically live. Do not touch metal parts when cutting into a
wall; grasp only the insulated surfaces on the tool. Make
sure hidden electrical wiring, water pipes, and mechanical
hazards are not in the blade path when cutting into a wall.
