NOTICE
If the battery is not removed, there is the risk that
the plug-in contacts on the cut-off machine and
battery become corroded. Such corrosion can
cause irreparable damage to the cut-off machine
and battery.
Allow the cut-off machine or battery to dry out
separately if they are wet after use.
2.15 Vibrations
Prolonged use of the power tool may result in
vibration-induced circulation problems in the
hands (whitefinger disease).
No general recommendation can be given for the
length of usage because it depends on several
factors.
The period of usage is prolonged by:
– Hand protection (wearing warm gloves)
– Work breaks
The period of usage is shortened by:
– Any personal tendency to suffer from poor cir‐
culation (symptoms: frequently cold fingers,
tingling sensations).
– Low outside temperatures.
– The force with which the handles are held (a
tight grip restricts circulation).
Continual and regular users should monitor
closely the condition of their hands and fingers. If
any of the above symptoms appear (e.g. tingling
sensation in fingers), seek medical advice.
2.16 Maintenance and repairs
Before all repair and maintenance work, always
switch off the machine, set the locking lever to ƒ
and remove the battery from the cut-off machine.
If the abrasive wheel starts inadvertently – risk of
injury!
The cut-off machine must be serviced regularly.
Do not attempt any maintenance or repair work
not described in the Instruction Manual. All other
work should be carried out by a servicing dealer.
STIHL recommends that maintenance and repair
work be carried out only by authorized STIHL
dealers. STIHL dealers receive regular training
and are supplied with technical information.
Use only high-quality spare parts. Otherwise,
there may be a risk of accidents and damage to
the cut-off machine. If you have any questions in
this respect, consult a servicing dealer.

STIHL recommends the use of genuine STIHL
spare parts. They are specifically designed to
match your cut-off machine and meet your per‐
formance requirements.
Do not modify the cut-off machine in any way –
this can be extremely dangerous –risk of acci‐
dents!
Check existing electrical contacts, power cords
and power plug of the charger regularly for
undamaged insulation and aging (brittleness).
Electrical components, e.g., the power cord of
the charger, may only be repaired and/or
replaced by qualified electricians.

Reactive Forces

The most frequently occurring reactive forces are
kickback and pull-in.
3.1 Kickback
Danger of kickback – Kickback can
result in fatal injuries.
Kickback occurs when the cut-off machine is
suddenly thrown up and back in an uncontrolled
arc towards the operator.
Kickback occurs if, for example, the abrasive cut‐
ting wheel
– gets jammed – especially the upper quarter, or
– is abruptly braked through friction contact with
a solid object
Reducing the risk of kickback
– Work cautiously and methodically
– Hold the cut-off machine firmly with both
hands and maintain a secure grip
