GENERAL SAFETY PRECAUTIONS
English
–
11
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.
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.
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 screen.
Spark arrestor muffler
The spark arrestor muffler controls the exhaust noise and
prevents hot, glowing particles of carbon from leaving the
muffler. Make sure the spark arrestor screen is in good
repair and properly seated in the muffler.
Certain internal combustion engines operated on forest,
brush and/or grass-covered areas in some states, are
required to be equipped with a spark arrestor. This
requirement also applies to all US Forest Service lands.
In some of these areas, the spark arrestor system must
be certified per USDA Forest Service Regulation SAE
J335. Check with your local state authorities fo specific
regulations in your area. Failure to follow these
regulations is in violation of the law.
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.
!
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.
!
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!
CAUTION! During operation, the muffler or catalytic
muffler and surrounding cover become hot. Never
suspend the saw on a lanyard with the engine running.
Always wear proper protective clothing to protect your
lower body from sharp saw chain and hot muffler.
Always keep exhaust area clear of flammable debris
during transportation or when storing, otherwise serious
property damage or personal injury may result.
!
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.
