Operating instructions
Note:
Before using the tool, read the instruction book carefully.
INTENDED USE
The machine is intended for sawing wood, plastic, metal, and building
materials while resting firmly on the workpiece. It is suitable for
straight and curved cuts. When using the appropriate bimetal saw
blades, it is possible to cut flush to the workpiece surface. The saw
blade recommendations must be observed.
KNOW YOUR RECIPROCATING SAW
vibrafree™ RECIPROCATING SAW
are uniquely designed to cancel
out the saw’s vibration in every load condition. This active vibration
canceling technology makes this saw more comfortable and easy to
use, taking the vibration out of the saw, the workpiece, your hands
and arms, and putting this energy to work sawing and removing
material.
TRIGGER SWITCH (See Fig. A)
Depress the switch to start and release it to stop your tool.
The blade plunger stroke rate can be adjusted from the minimum
to maximum by the pressure you apply to the trigger. Apply more
pressure to increase the speed and release pressure to decrease
speed. (See Fig. A)
VARIABLE SPEED DIAL (See Fig. B)
Adjust the variable speed dial to increase or decrease the speed
according to the material, material thickness and blade specification
to be used. Refer to the table to select the proper speed for the
workpiece to be cut. In general, higher speeds will allow you to cut
workpieces faster but the service life of the blade will be reduced.

Note:
• If the tool is operated continuously at low speeds for a long period
of time, the operation life of the motor will be reduced.
• The variable speed control can be turned only as far as 6 and back
to 1. Do not force it past 6 or 1, or the speed adjusting function may
no longer work.
HAND GRIP AREAS (See Fig. C)
Always hold your saw firmly with both hands when operating.
TOOL-FREE BLADE FITTING (See Fig. D, E)
To install the blade, disconnect the saw from power supply. If
necessary, extend the pivoting blade foot away from the blade clamp
for easier access. Pull the tool-free blade clamp lever (3) up with your
