Cutting Equipment - Husqvarna 3120XP Operator's Manual

Muffler
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to the
machine.
If the muffler on your machine is fitted with a spark arrestor
mesh this must be cleaned regularly. A blocked mesh will
cause the engine to overheat and may lead to serious
damage.
Never use a muffler if the spark arrestor mesh is missing
or defective.
WARNING! Never use a machine with faulty
!
safety equipment. The machine's safety
equipment must be checked and maintained
as described in this section. If your machine
fails any of these checks contact your
service agent to get it repaired.

Cutting equipment

This section describes how to choose and maintain your
cutting equipment in order to:
• Reduce the risk of kickback.
• Reduce the risk of the chain breaking or jumping.
• Obtain maximum cutting performance.
• Extend the life of cutting equipment.
General rules
• Only use cutting equipment recommended by us!
See the Technical data section.
SAFETY INSTRUCTIONS
• Keep the chain's cutting teeth properly sharpened!
Follow our instructions and use the recommended
file gauge. A damaged or badly sharpened chain
increases the risk of accidents.
• Maintain the correct raker clearance! Follow our
instructions and use the recommended raker gauge.
Too large a clearance increases the risk of kickback.
• Keep the chain properly tensioned! If the chain is slack
it is more likely to jump off and lead to increased wear on
the bar, chain and drive sprocket.
• Keep cutting equipment well lubricated and properly
maintained! A poorly lubricated chain is more likely to
break and lead to increased wear on the bar, chain and
drive sprocket.
Cutting equipment designed to minimise
kickback
WARNING! Faulty cutting equipment or the
!
wrong combination of bar and chain
increases the risk of kickback! Use only the
bar and chain combinations that we
recommend. See the Technical data section.
The only way to avoid kickback is to make sure that the
kickback zone of the bar never touches anything.
By using cutting equipment with "built-in" kickback reduction
and keeping the chain sharp and well-maintained you can
reduce the effects of kickback.
Bar
The smaller the tip radius the smaller the kickback zone and
the lower the chance of kickback.
