Cutting Equipment - Husqvarna 346XP/ 351 Operator's Manual

GENERAL SAFETY PRECAUTIONS
Cutting hardwoods (most broadleaf trees) creates more
vibration than cutting softwoods (most conifers). Cutting with
cutting equipment that is blunt or faulty (wrong type or badly
sharpened) will increase the vibration level.
WARNING! Overexposure to vibration can
!
lead to circulatory damage or nerve damage
in people who have impaired circulation.
Contact your doctor if you experience
symptoms of overexposure to vibration.
Such symptoms include numbness, loss of
feeling, tingling, pricking, pain, loss of
strength, changes in skin colour or
condition. These symptoms normally appear
in the fingers, hands or wrists. These
symptoms may be increased in cold
temperatures.
Stop switch
Use the stop switch to switch off the engine.
Muffler
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
WARNING! The exhaust fumes from the
!
engine are hot and may contain sparks
which can start a fire. Never start the
machine indoors or near combustible
material!
In areas with a hot, dry climate there is a high risk of fires.
These areas are sometimes subject to government rules
requiring among other things the muffler must be equipped
with an approved type of spark arrestor mesh.
CAUTION! The muffler gets very hot during and after use.
This also applies during idling. Be aware of the fire hazard,
especially when working near flammable substances and/
or vapours.

WARNING! Never use a saw without a
!
muffler, or with a damaged muffler. A
damaged muffler may substantially increase
the noise level and the fire hazard. Keep fire
fighting equipment handy. If a spark arrestor
screen is required in your area, never use
the saw without or with a broken spark
arrestor screen.

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 saw chain breaking or jumping off
the bar.
• Obtain optimal cutting performance.
• Extend the life of cutting equipment.
• Avoid increasing vibration levels.
General rules
• Only use cutting equipment recommended by us!
See instructions under the heading Technical data.
• 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 depth gauge setting! Follow our
instructions and use the recommended depth gauge
clearance. 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.
