Cutting Equipment - Husqvarna 334T Operator's Manual

GENERAL SAFETY PRECAUTIONS
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.
Cutting equipment designed to reduce
kickback
WARNING! Faulty cutting equipment or the
!
wrong combination of bar and saw chain
increases the risk of kickback! Only use the
bar/saw chain combinations we recommend,
and follow the filing instructions. See
instructions under the heading Technical
data.
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 lower the chance of kickback.
Chain
A chain is made up of a number of links, which are available
in standard and low-kickback versions.
IMPORTANT! No saw chain design eliminates the danger
of kickback.
WARNING! Any contact with a rotating saw
!
chain can cause extremely serious injuries.
Some terms that describe the bar and chain
To maintain the safety features of the cutting equipment, you
should replace a worn or damaged bar or chain with a bar and
chain combinations recommended by Husqvarna. See
instructions under the heading Technical Data for a list of
replacement bar and chain combinations we recommend.
