Follow the maintenance regulations and the
instructions for changing tools.
19. Starting up
Always wear safety goggles, ear muffs, protec-
tive gloves and heavy-duty work clothes!
Never use the chainsaw when standing on a ladder,
in a tree or in any other instable places. Do not use
above shoulder height and do not saw with one
hand.
Use the saw only with approved extension cables
which have the prescribed insulation and connec-
tions designed for outdoor use (approved rubber-
sheathed cables) and which fit the machine plug. To
switch on, hold the front grip (1) with your left hand,
with your right hand holding the rear grip (10).
To switch on:
Simultaneously press the safety lock-off (19) and
ON/OFF switch (18). Check to ensure the chain
brake is working properly.
If the chainsaw does not run, the chain
i
brake must be released at the front finger
guard (2). Be sure to read the sections
„Chain brake" and „Releasing the chain
brake" on this point.
After switching on, the chainsaw will run imme-
diately at high speed.
To switch off: Release the ON/OFF switch (18).
Only put down the chain saw after the chain has
stopped rotating!
After working with the chainsaw, you should
always: Clean the saw chain and chain bar. Attach
the chain guard.
Machine protection
Never use the machine in the rain or
in damp conditions.
IIf the extension cable is damaged,
pull the power plug immediately.
Never work with a damaged cable.

Check the machine for damage. Before using your
tool again, check the safety devices or any slightly
damaged parts to ensure that they are in good wor-
king order. Make sure the moving parts are working
correctly. All the parts must be correctly assembled
and meet all the conditions required to ensure that
the machine works correctly. Any damaged safety
devices and parts must be properly repaired or repla-
ced immediately by a Customer Service workshop or
the company ISC-GmbH, unless there are instruc-
tions to the contrary in this operating manual.
Notes on working practice
Kick-back
When cross-cutting always set the claw stop
against the timber you want to saw (see Fig. 4).
Always set the claw stop before cross-cutting.
Only then switch on the machine and start
sawing into the wood. Pull the machine upwards
at the rear and lead the direction with the front
grip. Use the claw stop as a fulcrum. To repositi-
on for further cutting, exert slight pressure on the
front grip. Pull the saw back slightly during this
process. Position the claw stop further down the
cut and pull up the rear grip once again (see Fig.
5).
Plunge cuts and horizontal cuts may only be car-
ried out by professionals (high risk of kick-back;
see Fig. 6).
For horizontal cuts, position the saw at the smal-
lest possible angle. This requires extreme cauti-
on, as the claw stop cannot be applied in this
case.
If the chain gets stuck when sawing with the
upper side it may be thrust toward the operator.
For this reason you should saw wherever possi-
ble with the bottom side, as the chainsaw will
then be thrust away from the body towards the
wood (see Fig. 7 and 8).
When lopping off branches, the chainsaw should
be supported wherever possible against the
trunk. Do not cut with the tip of the chain bar (risk
of kick-back; see Fig. 6).
Watch out for trunks rolling towards you.
Kick-back!
The chainsaw is likely to recoil if the tip of the
chain bar (especially the top quarter) accidentally
touches wood or any other solid objects. In this
case the saw will move uncontrollably and will be
hurled towards the operator at full power (risk of
injury!).
