Tensioning The Chain; Lubricating Cutting Equipment - Husqvarna 455e rancher ii Operator's Manual

Tensioning the chain

WARNING! A slack chain may jump off
!
the bar and cause serious or even fatal
injury.
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up
the slack.
Check the chain tension every time you refuel. NOTE! A
new chain has a running-in period during which you
should check the tension more frequently.
Tension the chain as tightly as possible, but not so tight
that you cannot pull it round freely by hand.

• Loosen the bar nuts that hold the clutch cover/chain
brake. Use the combination spanner. Then tighten the
bar nuts by hand as tight as you can.
• Raise the tip of the bar and stretch the chain by
tightening the chain tensioning screw using the
combination spanner. Tighten the chain until it does
not sag from the underside of the bar.
• Use the combination spanner to tighten the bar nuts
while lifting the tip of the bar at the same time. Check
that you can pull the chain round freely by hand and
that it does not sag from the underside of the bar.
The position of the chain tensioning screw on our chain
saws varies from model to model. See instructions under
the heading What is what? to find out where it is on your
model.

equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
Chain oil
Chain oil must demonstrate good adhesion to the chain
and also maintain its flow characteristics regardless of
whether it is warm summer or cold winter weather.
As a chain saw manufacturer we have developed an
optimal chain oil which has a vegetable oil base. We
recommend the use of our own oil for both maximum
