mer head on the ground during opera-
tion.

Using a Brushcutter
With a Trimmer Head
CAUTION!
Operation at low rpm can lead to
premature clutch failure.
Trimming and Mowing Grass
Hold the unit so the trimmer head is angled
slightly into the area to be cut. To ensure
maximum trimmer-line service life, cut only
with the tip of the trimmer line. To prevent
grass clippings from being thrown back
towards the operator or wrapping around
the gearcase, swing the unit’s trimmer
head from left to right while cutting. Keep
the trimmer head horizontal.
Operate at full throttle while cutting grass.
Engine Operating Speeds
Muffler
Prior to each work day, perform the
following:
Remove the dirt and debris from the
engine, check the cooling fins and air
cleaner for clogging, and clean them
as necessary.
Carefully remove any accumulations
of dirt or debris from the muffler and
fuel tank. Dirt buildup in these areas
can lead to engine overheating, fire, or
premature wear.
Check for loose or missing screws or
components. Make sure the cutting
attachment is securely fastened.
Check the machine for leaking fuel or
grease.
Daily Maintenance
WARNING!
Never operate this machine
with a damaged or missing muffler!
Operating with missing or damaged
exhaust components is a fire hazard,
and may also damage your hearing.
Edging
Tilt the handle about
100° to the left (from
horizontal) and move
forward, holding the unit
so that the trimmer head
cuts vertically.
