If the chainsaw does not run, the chainbra
ke must be released at the front finger
guard (1). 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 (5). 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.
If 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!).

You can avoid accidents by not sawing
with the tip of the chain bar as this may
cause the saw to rear up suddenly. Always
use the complete safety equipment and
clothes when working with the saw.
Make sure your work piece is firmly secu-
red.
Use clamps to stop the work piece from
slipping. This also makes it easier to opera-
te the machine with both hands.
Kick-back will result in an uncontrollable motion of
the saw. This represents the danger of severe inju-
ries. Never saw with a slack or blunt chain. A
poorly sharpened chain increases the risk of kick-
back. Never saw above shoulder height.
20. Tips on chainsaw use
Sawing up wood
(See Fig. 4 and 5)
To saw up wood, please observe the safety regulati-
ons and proceed as follows: Make sure the wood to
be sawed cannot slip. Clamp short pieces of wood in
place before sawing. Saw only wood or wooden
objects. When sawing, make sure that no stones or
nails are touched as these could be thrown out and
