shoe, slowly pull
the trigger to be
sure the blade al-

Impact Protection System
All models are equipped with a unique patented
gearing system that provides efficient power trans-
mission and extended life in the most difficult cut-
ting applications. This durable system will absorb
impacts, blade lock ups, and motor stalls. These
models can be used for extreme cutting applications
such as large diameter pipe, thick metal, pallets, and
heavy demolition and renovation work as well as for
general purpose cutting.

optimal cutting positions and comfort. The handle can
be locked into one of eight (8) detent positions, one at
every 45° angle.
To rotate the handle:
1. Unplug the tool.
2. Press in the handle rotation
button.
3. Rotate the handle to the
desired position.
4. Release the handle rotation
button. This will lock the
handle firmly into position.
NOTE: Make sure the handle does not rotate before
using the tool.

switch. The tool may be operated with straight recipro-
cating (non orbital) or orbital action. Straight reciprocat-
ing action should be used when a smooth cut is needed.
Orbital action is recommended for fast, aggressive
cutting. The optimal orbital action should be determined
by the user for their specific cutting requirements.
1. For straight reciprocating action, move the orbit
control switch to the straight cut symbol
2. For orbital action, move the orbit control switch to-
wards the orbital cut symbol
The amount of orbital action may be adjusted by mov-
ing the orbital control switch to any position between
the two symbols. For larger orbital action, move the
orbit control switch closer to the orbital cut symbol
For smaller orbital action, move the orbit control switch
closer to the straight cut symbol
Orbital action may be adjusted when the tool is running.
NOTE: Orbital action will not operate if the blade is
installed upside down.
Selecting the Speed Range
The speed control dial controls
the maximum strokes per
minute. The speed will re-

dial setting by use of the
trigger switch. Refer to the
chart for recommended dial
settings.

user preference.

control switch. It may be operated at any speed from
zero strokes per minute to full speed. Always start tool
before blade contacts the workpiece. To vary the speed,
simply increase or decrease the pressure on the trigger.
The further the trigger is pulled, the greater the speed.
To stop the tool, release the trigger and allow the tool

to stop completely before removing from a partial cut
or before laying the tool down.
For straight or contour cutting from an edge, line the
blade up with your cutting line. Before the blade con-
tacts the workpiece, grasp the handle firmly and pull
the trigger. Then guide the tool along your cutting line.
Always hold the shoe flat against the workpiece to avoid
excessive vibration.
Begin cutting at a slow speed, gradually increasing
speed as you cut. When cutting into metals or hard
materials that can not be cut from an edge, drill a
starting hole larger than the widest part of the blade.
Extend blade life by using a solid blade cutting lubricant.
