aprecautionarymeasure.
The
muffler
keeps the noise levels
to
a minimum and sends the
exhaust fumes away from the operator. Do not
use
the product
if
the muffler
is
missing
or
defective. A defective muffler increases
the noise level
and
the risk
of
fire. Examine the muffler regularly
to
make sure
that
it
is
attached correctly
and
notdamaged.
Muffler
and engine become
hot
and can cause burns. Do

to
another.
To
reduce exposure
to
vibration,
limit
the
hours
of
operation
and take periodic breaks
to
minimize repetition
and
rest
your
hands.
Reduce
the
speed
and
force in which you do the repetitive
movement. Try
to
fill
each
day
with
jobs where operating hand-
held powerequipment
is
not
required.
