flying shavings can cause injury. Wear hearing
protection for protection against continuous
noise in the work place. Wear a designated dust
mask for protection against airborne dust.
TO PREVENT ACCIDENTS
• Make sure that the ON/OFF switch is not
pressed down or locked by the setting button.
Connect the power plug to a corresponding
power outlet.
• Switch the jigsaw on only with an inserted
saw blade.
• Use only flawless saw blades.lmmediately re-
place blunt, twisted, or cracked saw blades.
• Pay attention when working that the air
vents are not covered up or congested.
SWITCHING ON/OFF
& CONTINUOUS OPERATION
The saw is started by pressing the ON/OFF
switch, the switch can be mainted in the ope-
rating position by using the lock-on button.
The lock-on button can be released by press
and releasing the ON/OFF switch once more.
To release the lock-on button press the switch
and release it, the lock-on button will be de-
activated.
PENDULAR STROKE SETTING
When set to the pendular stroke, there will be
a forward and backward movement in addi-
tion to the up and down movement of the saw
blade. Through this, the saw accelerates and
the saw blade will be protected from damage.
The next table will indicate wich position of
the pendular movement to use.

The best combination of stroke reate and
pendular stroke setting is dependent upon the
workpiece. We reccommend to perform a test
run on a piece of scrap material. This way the
most appropriate setting can be achieved.
SETTING THE STROKE RATE
The stroke rate indicates the number of the up
and down movements per minute of the saw
blade. The required stroke rate depends on the
work load and workpiece. On one hand, an ad-
equate working speed should be reached, on
the other, a clean cut should be achieved.
• Select the desired speed with the turning
knob. To increase the speed turn the knob
counterclockwise. To decrease the speed turn
the knob clockwise.
• With fine saw blades a higher stroke rate
can be used; rough saw blades require lower
speed.
• After using the jigsaw for a longer period
with a high stroke rate, the power tool can
heat up intensely - allow the power tool to
cool down for 3 minutes running idle at maxi-
mum speed.
SAWDUST BLOWER
The sawdust blower leads an air jet to the saw
blade. The air jet keeps sawdust from covering
the cutting line while working.
The air flow can be switched on or off with the
vacuum flow control for the sawdust blower.
Ideal for working with wood, plastic and simi-
lar materials that produce large amounts of
sawdust.
ADJUSTING THE CUTTING ANGLE
Features
Pull the bottom plate forward and backward,
For fine/clean cutting
and incline it leftward and rightward by simply
edges, thin materials,
hard material loosening the screw on the bottom plate.
Hard materials
Adjust to the required angle to push forward
or pull backward the bottom plate ( The read-
Soft materials (saw
ings indicated in the U-shaped window of the

direction) pressing block on the bottom plate refer to
the inclination angle of the jigsaw cutting), so
that the corresponding wedge-shaped groove
can be wedged into the wedge bulge of the
machine body.
