KRESS 420 ST E Mode D'emploi page 21

20 English
Use the mains cable module 12 only for Kress
electric tools. Do not attempt to operate other
machines with the module.
EN
Damaged mains cable modules must not be used.
They must be replaced by a new Kress mains
cable module immediately.
Push the two unlocking buttons 13 and remove
the mains cable module 12 from the handle.
Use only an original Kress mains cable module
and at least a heavy rubber tube cable (H07RN-F).
Operation
Switching On and Off
Caution! Before switching on the sabre jig saw, the
dust cover 3 in front of the tappet must be lowered
again to the saw bench 4.
To switch on the device, slide the circuit
closer/breaker 1 to the front.
Pressing the swung-out front edge of the circuit
closer/breaker 1 will move it back to the Off
position.
Restarting protection (500 ST E)
The restarting protection feature pre-
vents uncontrolled restarting of the
machine after an interruption in the
power supply.
To restart the operation, switch the On/Off
switch 1 to the Off position and start the
machine again.
Full-wave control electronics (420 ST E)
The electronics are switched off by turning the
adjusting wheel to the max. position. The jigsaw
then operates at the max. idle running stroke rate.
Presetting the Stroke Rate
In devices with a setting dial 2, you can select the
speed using the setting dial 2 depending on the
area of application.
When under load, the digital electronic control
provides for more power.
1-2: Low stroke rate
3-4: Medium stroke rate
5-6: High stroke rate

-NOTE-
After longer periods of work at low stroke rate, the
machine can heat up considerably. Remove the
saw blade from the machine and allow the machine
to cool down by running it for approx. 3 minutes at
maximum stroke rate.
Pendulum stroke setting (500 ST E)
The change-over from setting 0 to II is effected by
means of the pendulum-stroke adjusting knob 14.
The coloured mark indicates the pendulum stroke
setting selected.
0 No orbital action
for glass, ceramics, soft steel, non-
ferrous metals, aluminium and pressed
materials.
I Small orbital action
for plastics for plywood.
II Large orbital action
for hardwood, soft wood, chipboard.
It should be noted that the values given are standard
values which may vary according to thickness and
hardness of material, grain direction, and also to
the condition of the saw blade.
The optimal orbital action setting for the respec-
tive application can be determined through practi-
cal testing. The following recommendations apply:
Select a lower orbital action setting (or switch
it off) for a finer and cleaner cutting edge.
For thin materials such as sheet metal, switch
the orbital action off.
For hard materials such as steel, work with
low orbital action.
For soft materials and when sawing in the
direction of the grain, work with maximum
orbital action.
Mitre cuts
The base plate can be adjusted in both directions
by 22.5° and 45°. 0°, 22.5° and 45° angles can be
fixed securely. Adjustments are made by loosen-
ing the clamping wheel 6 beneath the handle. As
soon as the toothed wheel work of the saw bench
mounting is released, the base plate 4 can be
turned to positions 22.5° or 45° and be tightened
again with the clamping wheel 6.
