12
Always operate the line trimmer at full throttle. Cut tall
grass from the top down. This will prevent grass from
wrapping around the lower shaft and line head which
may cause damage from overheating. If grass becomes
wrapped around the line head, STOP THE ENGINE,
disconnect the spark plug wire, Fig. 15, and remove the
grass. Prolonged cutting at partial throttle will result in
oil dripping from the muffler.
STARTING AND STOPPING
Rest the unit on a flat, firm place. Keep the cutting head
off the ground and clear of surrounding objects, as it
will start rotating upon starting of the engine.
Slowly press the primer bulb 7 times.
Set the Ignition switch (1) to the “I” position, Fig.16. Hold
the body of the machine with your hand and pull the
starter handle sharply until engine attempts to run,
Fig.17. Do not pull the pull starter handle more than 8
times.
Press in the choke button, Fig.18.
Pull the pull starter handle until the engine runs. Do not
pull the starter handle more than 6 times.
Allow the engine to run for 15 seconds.
Press down the safety lever (2) and squeeze the
throttle trigger (3) fully, Fig.16. The choke button will
return to it original position when the throttle trigger is
squeezed.
STOPPING THE ENGINE
Release the throttle trigger and run the engine for half a
minute.
Shift the ignition switch to the STOP “0” position.
Important! Except for an emergency, avoid stopping
the engine while pulling the throttle trigger.
EXPANDING THE CUTTING LINE
The length of the cutting line is controlled by tapping
the line head on grass while running engine at full
throttle.
Run engine at full throttle.
Tap the spool retainer on ground to make the cutting
line longer. The line advances each time the spool
retainer is tapped. Do not hold the spool retainer 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 line is too short you may not be able to
advance the cutting line by tapping it on the ground. If
so, stop the engine, and manually advance the line.
ADVANCING THE CUTTING LINE MANUALLY
Push the spool retainer down while pulling on cutting
lines to manually advance the string.
If the cutting line has receeded into the spool you will
have to remove the spool and feed the line through the
spool holes. Make sure the engine is off and remove the
spark plug wire then unscrew the spool retaining knob
in a anticlockwise direction. Make sure the two lines are
captured in the slots opposite each other on the spool
and each line is extended approximately 152 mm
beyond each slot.
Thread the strings into the spool holes in the line head.
Carefully push the spool into the line head (gently pull
the lines to the outside if necessary). When the spool is
positioned in line string head, grasp the strings and pull
sharply to release them from the slots in the spool.
Screw on the spool retaining knob in a clockwise
direction making sure it is securely fastened.
CUTTING TIPS
Keep the trimmer tilted toward the area being cut; this
is the best cutting area.
The trimmer cuts when passing the unit from right to
left. This will avoid throwing debris at the operator.
Use the tip of line to do the cutting; do not force the line
head into uncut grass. Wire and wooden fences cause
extra line wear, even breakage. Stone and brick walls,
curbs, and wood may wear the string rapidly.
Avoid trees and shrubs. Tree bark, wood mouldings,
siding, and fence posts can easily be damaged by the
string.
DEBRIS SHIELD LINE TRIMMING CUT-OFF BLADE
(FIG.19)
The trimmer is equipped with a line trimming cut-off
blade on the grass deflector. For best cutting, advance
the line until it is trimmed to length by the cut-off blade.
Advance the line whenever you hear the engine running
faster than normal, or when trimming efficiency
diminishes. This will maintain best performance and
keep the line long enough to advance properly.
METAL BLADE USAGE
Check the nut to fasten the blade and be sure the nut
has no fault, and no abrasion.
Be sure that the blade and the holder have been
fastened according to instruction and the blade turns
smoothly without abnormal noise.
WARNING! The rotating parts fastened incorrectly may
cause serious accident to the operator.
Make sure that the blade is not bent, warped, cracked,
broken or damaged.
If you find any error to the blade, discard it and change
new one which is recommended by your authorised
service centre.
By using the shoulder strap, hang the unit on your right
side. Adjust the strap length so that the cutting head
may become parallel to the ground.
WARNING! Make sure to use shoulder strap and debris
guard. If not, it is very dangerous when you slip or lose
your balance.
