Chain Brake - Stihl MS 192 T Instruction Manual

Chain Brake

Locking chain with chain brake
– in an emergency,
– when starting,
– at idling speed.
The chain is stopped and locked when
when the hand guard is pushed toward
the bar nose by the left hand –
or when brake is activated by inertia in
certain kickback situations.
MS 192 T
Releasing the chain brake
: Pull the hand guard back toward the
front handle.
Always disengage chain brake
before accelerating engine and
before starting cutting work. The
only exception to this rule is when
you check operation of the chain
brake.
High revs with the chain brake
engaged (chain locked) will quickly
damage the powerhead and chain
drive (clutch, chain brake).
The chain brake is also activated by
the inertia of the front hand guard
if the kickback force of the saw is high
enough. The hand guard is accelerated
toward the bar nose.
The chain brake will operate only if the
hand guard has not been modified in any
way.
Check operation of chain brake
Before starting work:
Run engine at idle speed, engage the
chain brake (push hand guard toward
bar nose). Accelerate up to full throttle
for no more than 3 seconds - the chain
must not rotate. The hand guard must be
free from dirt and move freely.
