English (Original instructions)
Always operate the product at full throttle. Prolonged
cutting at partial throttle will result in lubricant dripping from
the silencer. 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, and remove the grass.
CUTTING TIPS
See fi gure 6.
■ Avoid hot surfaces by always keeping the tool away
from your body. (Proper operating position shown in
figure 5.)
■ Keep the product tilted toward the area being cut; this
is the best cutting area.
■ The product cuts when passing the product from
right to left. This will avoid throwing debris at the
operator. Avoid cutting in the dangerous area shown
in illustration.
■ Use the tip of the string to do the cutting; do not force
the string head into the uncut grass.
■ Wire and picket fences cause extra string wear, even
breakage.
■ Stone and brick walls, kerbs and wood may wear
string rapidly.
■ Avoid trees and shrubs. Tree bark, wood mouldings,
cladding and fence posts can be easily damaged by
the string.
ADVANCING THE LINE
See fi gure 7.
Line advance is controlled by tapping the string head on
grass while running engine at full throttle.
■ Run engine at full throttle.
■ Tap the knob on ground to advance string. The string
advances each time the head is tapped. Do not hold
the knob on the ground.
NOTE:
The line trimming cut-off blade on the grass
de fl ector 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 line.
ADVANCING THE CUTTING LINE MANUALLY
■ Stop the engine.
■ 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 performance and may void
your warranty.
■ Always stop the engine and allow it cool before making
any maintenance.
■ You may make adjustments and repairs described
in this user manual. For other repairs, contact the
authorized service agent.
■ Consequences of improper maintenance may
include excess carbon deposits resulting in loss of
performance and discharge of black oily residue
dripping from the silencer.
■ For replacement line, use only nylon filament line of
the diameter described in the specification table of this
manual.
■ After extending new cutter line, always return the
product to its normal operating position before starting.
■ The cutting attachment must not work in idle mode. If
this requirement is not satisfied, the clutch has to be
adjusted or the machine needs an urgent maintenance
by a qualified technician.
■ After each use, clean the product with a soft dry cloth.
■ Check all nuts, bolts and screws at frequent intervals
for proper tightness to ensure the product is in safe
working condition. Any part that is damaged should be
properly repaired or replaced by an authorised service
