ON/STOP SWITCH
The ON/STOP switch is used to stop
engine. To stop the engine, push and

PRIMER BULB
The PRIMER BULB removes air from
the carburetor and fuel lines and fills
them with fuel. This allows you to start
the engine with fewer pulls on the
starter rope. Activate the primer bulb
by pressing it and allowing it to return
to its original form.
THROTTLE LOCK-OUT
The THROTTLE LOCK-OUT must be
pressed with the palm of your hand as
you grip the throttle handle before the
trigger can be used. This feature
prevents you from accidentally
squeezing the throttle trigger.
CHOKE
The CHOKE helps to supply fuel to the
engine to aid in cold starting. Activate
the choke by moving the choke lever to
the FULL CHOKE position. After the en-
gine attempts to start, move the choke
lever to the HALF CHOKE position. Once
engine has started, move the choke le-
ver to the OFF CHOKE position.
BEFORE STARTING ENGINE
,_/LWARNING: Be sureto read
the fuel information in the safety rules
before you begin. If you do not under-
stand the safety rules, do not attempt
to fuel your unit. Call 1-800-235-5878.

runs, but no more than 6 pulls.
3. Allow engine to run 15 seconds,
then move the choke lever to OFF
CHOKE and begin normal operation.
NOTE: If engine has not started, pull
starter rope 5 more pulls. If engine still
does not run, it is probably flooded.
STARTING A FLOODED ENGINE
Flooded engines can be started by
placing the choke lever in the OFF
CHOKE position; then, pull the rope to
clear the engine of excess fuel. This
could require pulling the starter handle
many times depending on how badly
the unit is flooded.
If the unit still doesn't start, refer to
TROUBLESHOOTING TABLE or call
1-800-235-5878.
OPERATING INSTRUCTIONS
To maximize operating efficiency, do
not run the engine for longer than 1
minute at a time at full throttle.
OPERATING POSITION
ALWAYS USE:
Hearing
Protection Eye Protection
Long
Pants
Heavy _411 _
Shoes
Cutfrom yourle_to yourright.
WAR NI N G: Always wear eye
protection and hearing protection. Never
lean over the trimmer head. Rocks or
debris can ricochet or be thrown into
eyes and face and cause blindness or
other serious injury.
When operating unit, stand as shown
and check for the following:
• Wear eye protection, hearing protec-
tion and heavy clothing.
• Hold trigger handle with right hand
and assist handle with left hand.
• Hold unit so that engine is below
waist level.
• Cut only from your left to your right to
ensure debris is thrown away from
you. Without bending over, keep line
near and parallel to the ground and
not crowded into material being cut.
Do not run the engine at a higher speed
than necessary. The cutting line will cut
efficiently when the engine is run at less
than full throttle. At lower speeds, there
is less engine noise and vibration.
Always release the throttle trigger and
allow the engine to return to idle
speed when not cutting.
HOW TO STOP YOUR UNIT
• Release the throttle trigger.
• Push and release the engine ON/
STOP switch.
CUTTING METHODS
,_WARNING: Use minimum
speed and do not crowd the line when
cutting around hard objects (rock,
gravel, fence posts, etc.), which can
damage the trimmer head, become
entangled in the line, or be thrown
causing a serious hazard.
• The tip of the line does the cutting.
You will achieve the best perform-
ance and minimum line wear by not
crowding the line into the cutting
area. The right and wrong ways are
shown below.
Tip of line does the
Right
Line crowded into
work_
Wro°
• The line will easily remove grass
and weeds from around walls,
fences, trees and flower beds, but it
also can cut the tender bark of trees
or shrubs and scar fences.
• For trimming or scalping, use less
than full throttle to increase line life
and decrease head wear, especially:

SCALPING - The scalping technique
removes unwanted vegetation down to
the ground. Hold the bottom of the trim-
mer head about 3 inches (8 cm) above
the ground and at an angle. Allow the
tip of the line to strike the ground
around trees, posts, monuments, etc.
This technique increases line wear.
Scalping
MOWING - Your trimmer is ideal for
mowing in places conventional lawn
mowers cannot reach. In the mowing
position, keep the line parallel to the
ground. Avoid pressing the head into
the ground as this can scalp the
ground and damage the tool.
Mowing
SWEEPING -The fanning action of the
rotating line can be used to blow away
loose debris from an area. Keep the line
parallel to and above the area surface
and swing the tool from side to side.
