Tensioning The Chain - Husqvarna 445, 445e, 450e 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 nut that holds the clutch cover and
chain brake. Use the combination spanner. Then
retighten the bar nut as tightly as you can by hand.
• 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.
