Cutting Equipment - MTD 450E Operator's Manual

GENERAL SAFETY PRECAUTIONS
Muffler
Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to reduce vibration and make
operation easier.
The machine's vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine's handle unit.The body of the
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.
A 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 feel ng, tingling,
pr eking, pain, loss of Strength, changes
in skin caleur or conditiemThese
symptoms normally appear in the
fingers, hands or wrists.These
Symptoms may be ncrease d n cold
temperatures.
Stop switch
Use the stop switch to switch off the engine.
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
I A WARNING! The exhaust fumes from the
engine are hot and may contain sparks |
which can start a fire. Never star t the |
roac!!no 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 screen.
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.
