Cutting Equipment - Husqvarna 55 Rancher Operator's Manual

chain saw, including the cutting equipment, is insulated
from the handles by vibration damping units.
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.

GENERAL SAFETY PRECAUTIONS
For mufflers it is very important that you follow the
instructions on checking, maintaining and servicing your
machine. See instructions under the heading Checking,
maintaining and servicing the machine's safety
equipment.
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.
