OPERATING
THE TRIMMER
See Figure

A
wanrurruc,
Always
position
the unit on the operator's right side.
The
use
of
the
unit on the operator's left side will expose
the user
to hot
surfaces and can result in oossible
burn
lnturv.
A wnnnrnc'
To avoid burns
from hot
surfaces,
never operate unit with
the bottom of
the
enoine above
waist level.
Hold the trimmer with
your
right
hand on the rear handle and
your
left hand on
the front handle. Keep a firm
grip
with both
hands while
in
ooeration.
Trimmer should be held at a com-
fortable
position
with the rear handle about hip height.
Always
operate trimmer at full throttle. Cut
tall
grass
from
the
top down. This will
prevent grass
from wrapping around
the shaft
housing and string head
which could cause
damage
from overheating.
lf
grass
becomes
wrapped around
the string head, STOP
THE ENGINE, disconnect the spark
plug
wire, and
remove the
grass.
Prolonged cutting at
partial
throttle
will result in oil dripping from the muffler.
