Releasing the chain brake
• Pull the hand guard back toward the
front handle.
r_ 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) wilt quickly
damage the powerhead and chain
drive (clutch, chain brake).
Engfish / USA
The chain brake is designed to be
activated also by the inertia of the
front hand guard
if the forces are sufficiently high. The
hand guard is accelerated toward the
bar nose - even if your left hand is not
behind the hand guard, e.g. during a
felling cut. The chain brake wilt operate
only if it has been properly maintained
and 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.
