2.Press the primer bulb (1) 10 times.
NOTE: After the 7th press, the fuel should be visible
in the primer bulb. If not, continue pressing until the
fuel is visible.
3.Set the choke lever (2) to choke position.
4.Hold down the throttle lock (5) and then squeeze the
throttle trigger (7) .
5.Hold the foam handle tightly with left hand and pull
the starter grip (4) upwards with right hand in a quick,
firm and consistent motion until the engine attempts to
start. Do not pull the starter grip more than 4 times.
6.Set the choke lever to choke position.
7.Pull the starter grip until the engine starts. Do not pull
the starter grip more than 6 times.

firm and consistent motion until the engine starts.
position.
TO STOP THE ENGINE:
nPress the hold the switch in the stop “ O ” position
until the engine stops.
OPERATING THE TRIMMER (Fig. 5)
Hold the trimmer with the right hand on the rear handle
and the left hand on the front handle. Keep a firm grip
with both hands while in operation. Trimmer should be
held at a comfortable position with the rear handle about
hip height.
Inspect the product before use and after dropping or
other impacts to identify any significant defects.
Always operate trimmer at full throttle. Cut tall grass
from the top down. This will prevent grass from wrapping
around the shaft housing and bump head which may
cause damage from overheating. If grass becomes
wrapped around the bump head, stop the engine,
disconnect the spark plug wire, and remove the grass.
Prolonged cutting at partial throttle will result in lubricant
dripping from the silencer.
CUTTING TIPS (Fig. 6)
nAvoid hot surfaces by always keeping the tool away
from your body. (Proper operating position shown in
figure 5.)
nKeep the trimmer tilted toward the area being cut; this
is the best cutting area.
nThe trimmer cuts when passing the unit from right to
left. This will avoid throwing debris at the operator.
Avoid cutting in the dangerous area shown in
illustration.
n Use the tip of string to do the cutting; do not force
bump head into uncut grass.
n Wire and picket fences cause extra line wear, even
breakage.
n Stone and brick walls, curbs, and wood may wear line
rapidly.
n Avoid trees and shrubs. Tree bark, wood mouldings,
siding, and fence posts can easily be damaged by the
string.
ADVANCING THE LINE (Fig. 7)
For Reel EasyTM Only
Line advance is controlled by tapping the bump head on
grass while running engine at full throttle.
n Run engine at full throttle.
n Tap the knob on ground to advance string. The string
advances each time the knob is tapped. Do not hold
the knob on the ground.
NOTE: The line trimming cut-off blade on the grass
deflector will cut the line to the correct length.
NOTE: If the string is worn too short you may not be able
to advance the string by tapping it on the ground. If so,
stop the engine, and manually advance the string.
TO ADVANCE THE CUTTING LINE MANUALLY:
n Stop the engine and disconnect the spark plug lead.
n Push the knob in while pulling on string(s) to manually
advance the line.
MAINTENANCE
WARNING
Use only original manufacturer's replacement
parts, accessories and attachments. Failure to
do so can cause possible injury, poor perfor-
mance and may void your warranty.
nYou may make adjustments and repairs described
here. For other repairs, have the trimmer serviced by
an authorized service agent.
nConsequences of improper maintenance may
include excess carbon deposits resulting in loss
of performance and discharge of black lubricanty
residue dripping from the muffler.
nMake sure all guards, straps, deflectors and handles
are properly and securely attached to avoid the risk of
personal injury.
■ The cutting attachment must not work in idle mode.
