Reactive Forces - Stihl MSE 170 C Instruction Manual

Electrical components, e.g. power cord,
may only be repaired or replaced by a
qualified electrician.
Check the chain catcher and replace it if
damaged.
Observe sharpening instructions – keep
the chain and guide bar in good
condition at all times for safe and correct
handling of the machine. The chain must
be properly sharpened, tensioned and
well lubricated.
Always change the chain, guide bar and
sprocket in good time.
Store chain lubricant in properly labeled,
safety-type canisters only. Store in a dry,
cool and safe location protected from
light and the sun.
If there is a problem with the chain
brake, switch off the saw immediately,
move the hand guard to ƒ and
disconnect the plug from the wall outlet
– risk of injury. Contact your servicing
dealer – do not use your saw until the
problem has been rectified (see "Chain
Brake").

Reactive Forces

The most common reactive forces are:
kickback, pushback and pull-in.
Dangers of kickback
Kickback can result in
fatal cuts.
Kickback occurs when the saw is
suddenly thrown up and back in an
uncontrolled arc towards the operator.
Kickback occurs if, for example,
The saw chain in the area of the
–
upper quarter of the guide bar nose
unintentionally comes into contact
with wood or a solid object – e. g.,
unintentionally touches another limb
during limbing
The saw chain at the nose of the
–
guide bar is briefly pinched in the cut
QuickStop chain brake:
This device reduces the risk of injury in
certain situations – it cannot prevent
kickback. If activated, the brake stops
the saw chain within a fraction of a
second –
refer to chapter "Chain brake" in this
Instruction Manual.
