Even when the unit is used as prescribed it is not
possible to eliminate all residual risk factors. The
following hazards may arise in connection with the unit’s
construction and design:
This unit produces an electromagnetic eld during
operation. This eld may, under some circumstances,
interfere with active or passive medical implants. To
reduce the risk of serious or fatal injury, we recommend
persons with medical implants to consult their physician
and the medical implant manufacturer before operating
this unit.
Inspect unit before each use. Replace damaged parts.
Check for fuel leaks. Make sure all fasteners are in
place and secure. Replace cutting attachment parts that
are cracked, chipped, or damaged in any way. Make
sure the cutting attachment is properly installed and
securely fastened. Be sure the cutting attachment shield
is properly attached and in the position recommended
by the manufacturer. Use only exible, nonmetallic line
recommended by the manufacturer. Never use, for
example, wire or wire-rope, which can break off and
become a dangerous projectile.
Do not operate the unit inside a closed environment,
such as a room or building; breathing carbon monoxide
from exhaust fumes can kill.
Mix and pour fuel outdoors where there are no sparks
and ames. Slowly remove the fuel cap only after
stopping the engine. Do not smoke while fueling or
mixing fuel. Wipe spilled fuel from the unit. Move at

CAUTION:
DECORATIVE TRIMMING
TRIMMING TIPS
TIPS FOR BEST RESULTS
ADJUSTING THE TRIMMING LINE
• Frequently check the trimming line length. Replace
the trimming line as needed. Refer to Replacing the
Trimming Line.
• DO NOT force the unit. Make shallow cuts in as many
passes as are necessary to achieve the desired
depth. Cut at a slow, even pace.
• Avoid hot surfaces by always keeping the tool away
from your body.
• Cut all grass from top to down. This will prevent grass
from wrapping around the shaft housing and string
head which could cause damage from overheating.
• If grass becomes wrapped around the string head,
STOP THE ENGINE, disconnect the spark plug wire,
and remove the grass.
• Use the tip of line to trim grass; do not force string
head into uncut grass.
• Avoid trees, owers, stones, walls and other objects
which can cause the line to break.
• Check and feed the line regularly to maintain full
cutting width and performance.
• To direct clippings away from the operator, tilt the
cutting head slightly down to the right; whenever
possible swing the trimmer in a left to right cutting
motion. There is an embossed arrow on the top of
the safety guard indicating the preferred left to right
direction of trimmer operation.
• Do not trim wet grass or weeds.
NOTE: Some line breakage will occur from:
This unit is equipped with a bump head. Trimming line
can be released from the cutting head without stopping
the engine. To release more line, lightly tap the bump
knob on the ground (Fig. 13) while operating the unit
at high speed. For best results, tap the bump knob on
bare ground or hard soil. Attempting to release line in
tall grass may stall the engine.
NOTE: Do not rest the cutting head on the ground while
the unit is running. Each time the bump knob is tapped,
about 1 inch (25.4 mm) of trimming line is released.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difcult when the cutting
line gets shorter.
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick vegetation
• Forcing the line into objects such as walls or fence
posts

CLEANING
If the engine will not idle properly:
1. Start the engine. Refer to Starting and Stopping.
2. Release the throttle control and let the engine idle.
• If the engine stops, increase the idle speed. Use a
small Phillips screwdriver to turn the idle speed screw
clockwise, 1/8 of a turn at a time, until the engine idles
smoothly.
• If the cutting head spins when the engine idles,
reduce the idle speed. Turn the idle speed screw
counterclockwise, 1/8 of a turn at a time, until the
cutting head stops moving.
The cutting attachment should never turn at idle. Turn
the idle speed screw counterclockwise to reduce the
idle RPM and stop the cutting attachment, or contact
customer support for adjustment and discontinue use
until the repair is made. Serious personal injury could
result from the cutting attachment turning at idle.
To avoid serious personal injury, always stop the engine
and allow it to cool before cleaning or maintaining the
unit.
The cutting head will move when adjusting the idle
speed. Wear all protective clothing and keep all
bystanders, children, and pets at least 50 ft. away. Make
adjustments with the unit supported by hand so that the
cutting head does not contact the ground or any object.
Keep all parts of your body away from the cutting head
and mufer. Failure to follow these instructions could
result in serious personal injury.
The cutting attachment should never turn at idle. Turn
the idle speed screw counterclockwise to reduce the
idle RPM and stop the cutting attachment, or contact
customer support for adjustment and discontinue use
until the repair is made. Serious personal injury could
