Switching On/Off
Brief Activation
Press the On/Off switch (2) and then let go again.
Continuous use
[F2]
Switching On
Press On/Off switch (2) and retain with lock-on button (3). •
Switching Off
Press and release On/Off switch (2). •
Stroke rate selection
(JS-570SGP; JS-750SGP; JS-800SGP)
With the tumbwheel (1), the required stroke rate can be selected
(also while running). [F3]
1-2 = low stroke rate
3-4 = medium stroke rate
5-6 = high stroke rate
Light pressure on the on/off switch (2) means low stroke- •
rate.
Increasing pressure on the on/off switch (2) results in higher •
stroke-rate.
Dust extraction
Dust extraction prevents large accumulations of
dust, high concentration of dust in the ambient air
and facilitates disposal.
For long periods of working with wood or for commercial use
on materials that produce dust that is detrimental to health,
the machine is to be connected to a suitable external dust
extraction device.
Pendulum action setting
(JS-570SGP; JS-750SGP; JS-800SGP)
The saw blade pendulum action that is adjustable in four steps,
makes possible the optimal adaptation of sawing advancing
(cutting speed), cutting performance and cut appearance of
the machined material.
For each downward movement, the saw blade is lifted off
the material, which facilitates sawdust ejection, reduces heat
generated by friction and increases the service life of the
saw blade. At the same time, the reduction of the necessary
advancing force provides fatigue-free working.
The lever for pendulum stroke adjustment (7) makes possible the
adjustment of the pendulum action in four steps. The switching
can take place with the machine running: [F4]
Step 0: No pendulum action;
Step 1: Small pendulum action;
Step 2: Medium pendulum action;
Step 3:
Large pendulum action;
The following basic recommendations are to be observed:
The smaller the pendulum step selected (or switched • «off»),
the finer and cleaner the cut edge;
When working with thin materials, like metal sheet,the •
pendulum action should be switched «off» (Step 0);
Materials such as soft wood cut in the direction of the grain, •
should be cut with the maximum pendulum action setting (Step
3).
Operating instructions
Sawing
Before sawing, make sure that the saw blade (5) is seated •
correctly and put the front guard (4) down as far as possible.
The base plate (8) of the jig saw must lie securely on its •
entire surface.
Do not force the saw; this cause the saw blade (5) to •
overheat and bend and/or break.
If material to be cut is thin, place it on an additional board/ •
plate to dampen vibrations and improve cutting.
For long cuts, lubricate the guide roller (6) now and then •
with a few drops of oil and let the machine cool down.
Wait until the saw blade (5) has come to a standstill before •
you put the device down.
Cutting angle adjustment
(JS-400SG; JS-570SGP; JS-800SGP)
To set the saw for bevel and angled cutting, undo the •
holding screws of the saw base with the hex key and push the
base back out of its rest position.
Set the cutting angle by angling the base to the right or to •
the left.
Tighten firmly both holding-screws. [F5] •
(JS-750 SGP)
Loosen the holding screw of the base plate with the hex •
key
Pull the locking lever (13). •
Rotate the base plate (8) and set the desired angle of the •
base by using markings on a scale.
Pull out the locking lever (13). •
Laser guide
(JS-800SGP)
For precision cutting, this jig saw is equipped with a switchable
laser guide. It projects an easily visible line in the direction of
the cut so that you can take a bearing at exactly one point.
This signal beam makes a perfectly straight cut possible even
without a guide. Switch on using the laser guide button (15) on
