Husqvarna 353 EPA III TrioBrake Chainsaw User Manual


 
GENERAL SAFETY PRECAUTIONS
English 9
The brake is applied when the front hand guard (B) is
pushed forwards or when the right-hand brake trigger (E)
is pushed up and forwards.
This movement activates a spring-loaded mechanism
that tightens the br
ak
e band (C) around the engine drive
system (D) (clutch drum).
The front hand guard is not designed solely to activate
the chain br
ak
e. Another important feature is that it
reduces the risk of your left hand hitting the chain if you
lose grip of the front handle.
The chain brake must be engaged when the chain saw is
star
ted to pre
vent the saw chain from rotating.
Use the chain brake as a ”parking brake” when starting
and when moving o
ver short distances, to reduce the risk
of moving chain accidentally hitting your leg or anyone or
anything close by.
To release the chain brake pull the front hand guard
bac
kwards, towards the front handle.
Kickback can be very sudden and violent. Most
kickbacks are minor and do not always activate the chain
brake. If this happens you should hold the chain saw
firmly and not let go.
The way the chain brake is activated, either manually or
automatically b
y the iner
tia release mechanism,
depends on the force of the kickback and the position of
the chain saw in relation to the object that the kickback
zone of the bar strikes.
If you get a violent kickback while the kickback zone of
the bar is f
arthest away from you the chain brake is
designed to be activated by the inertia in the kickback
direction.
If the kickback is less violent or the kickback zone of the
bar is closer to you the chain br
ake is designed to be
activated manually by the movement of your left hand.
In the felling position the left hand is in a position that
mak
es man
ual activation of the chain brake impossible.
With this type of grip, that is when the left hand is placed
so that it cannot affect the movement of the front hand
guard, the chain brake can only be activated by the
inertia action.
