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.

1. Low stroke speed (0-2400/min).
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.

2. High stroke speed (0-2700/min).
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.

Variable Speed Trigger
Switch
Your tool is equipped with a variable
speed trigger switch. The tool can be
turned "ON" or "OFF" by squeezing or
releasing the trigger. The blade plunger
stroke rate can be adjusted from the
minimum to maximum nameplate stroke
rate by the pressure you apply to the
trigger. Apply more pressure to increase
the speed and release pressure to
decrease speed (Fig. 1).
discontinue use of the tool if the
variable speed control ceases to
function. Subsequent loss of on/off
control of the trigger switch is likely.
Higher speed settings are generally used
for fast cutting or when softer cutting
materials such as wood, composite
materials, and plastics. Slower speed
settings are generally used when
precision is required or when cutting
harder materials. Materials typically cut
using slower speeds include sheet
metal, conduit, and pipe.

surface may result in electic shock or
electrocution if sawing into a blind area
where live wiring exits.
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.
