DUAL SPEED SELECTOR SWITCH
& TRIGGER LOCK
The stroke speed setting of the power tool can
be changed with the stroke speed selector
switch. However, this is not possible when the
On/Off switch is pressed.
Stroke speed selector switch – central
position:
The safety lock is activated.
The On/Off switch is blocked and
the machine is secured against
being switched on unintentionally.
1. Securely clamp the work.
2. Mark the line of cut and grasp the tool with
one hand on the handle and the other
placed on the insulated rubber boot over
the front housing.
Always operate the saw
W RNING
with the insulated boot on
the front housing. If you saw into a blind area
where live wiring exists, you may be shocked
or electrocuted.
3. Keep the saw footplate firmly against the
work to minimize counter-force (jumping)
and vibration.
4. Squeeze the trigger to start the tool. Let the
saw reach full speed before starting the cut.
Guide the saw so that the blade will move
along the marked line.
SAWING TIPS
Following a few simple tips will reduce the
wear on the workpiece, the tool and the
operator.
1. Blades cut on the draw or back stroke. On
fine work, such as paneling, fiberglass, etc.,
place the good side of workpiece facing
down.
2. Use the correct saw blade for the material
being cut and keep extra blades on hand to
use when others become dull. Replace
cracked or bent blades immediately.
3. Select the footplate projection settings, as
well as the appropriate cutting speed.
Stroke speed selector switch – left:
1. Low stroke speed.
The low stroke speed is suitable for
sawing hard materials such as
steel, non-ferrous metal, hard
plastics or for precision cuts in
wood and plunge cutting.
The low stroke speed enables sawing with less
vibrations.
Stroke speed selector switch – right:
2. High stroke speed.
The high stroke speed is suitable
for sawing soft materials.
The high stroke speed enables
quicker operational progress, e. g.,
for coarse cuts in wood.

Using the Saw

4. To reduce the risk of injury, be sure the
blade always extends beyond the footplate
and work throughout the stroke. Blades
may shatter if the front on the blade hits the
work and/or the footplate.
WRONG
5. When cutting metal:
- Apply a lubricant for easier, smoother,
faster cutting and longer blade life.
- For non-ferrous metals, aluminum,
bronze or brass, use a stick wax on the
blade.
- For ferrous metals, iron and steel, use
machine or cutting oil along the surface
to be cut.
6. When cutting thin metal, "sandwich" the
material between two pieces of scrap wood.
Clamp or put in a bench vise. One piece of
lumber on top of the metal can be used with
adequate clamping. Place your cut lines or
design on the wood.
7. Don't force the cutting. Let the saw and
blade do the work.
