Cutting
WARNING
● Always use the harness (if so equipped)
and wear the proper attire and protective
equipment when operating the unit. (Fig. 14)
● Keep others including children, animals,
bystanders and helpers outside the 15 m
hazard zone. Stop the engine immediately if
you are approached. (Fig. 15)
● When grass or vines wrap around
attachment, stop engine and attachment
and remove them. Continuing operation
with grass or vines wrapped around the
attachment may result in damages such as
early abrasion of the clutch.
Fig. 14 Fig. 15
NOTE
Use in accordance with local laws and
regulations.
12
English
Using a semi-auto cutting head
○ Set the engine at high speed when using this
attachment.
○ Cut grass from left to right. The cut grass will
be discharged away from the body, minimizing
transfer to your clothes. (Fig. 16)
○ Cut grass from right to left as the cutting
attachment of the curved drive shaft tube model
rotates clockwise.
○ With nylon cord, use about 3/4” (2 cm) of the end
of the cord to cut grass. Using the full length of
the cord will reduce rotation speed and make
cutting diffi cult.
Fig. 16
NOTE
Automatically feeds more nylon cutting line
when it is tapped at low rpm (not greater than
6,000 min
-1
).
WARNING
● This product is equipped with a line limiter
that will automatically cut any excess cord.
When operating the unit, do not remove the
guard or line limiter.
As the resistance is greater for nylon cords
as opposed to blades, mishandling could
increase engine load and result in damage.
● Do not use with the engine set at low
speeds. If the engine speed is low, grass
may wrap around the attachment, causing
the clutch to slip which could result in clutch
abrasion.
● With nylon cord cutters, always use over
5-7/8” (15 cm) of cord. If the length of
the cord is too short, rotation speed will
increase and may cause damage to the
nylon cord cutter. As the curved drive shaft
tube model in particular is not equipped with
a deceleration mechanism, the possibility
of increased rotation speed for the cutting
attachment is high.
Stopping (Fig. 17)
Decrease engine speed and run at an idle for a few
minutes, then turn off ignition switch (10).
10
Fig. 17
WARNING
A cutting attachment can injure while it
continues to spin after the engine is stopped
or Throttle trigger is released. When the
unit is turned off , make sure the cutting
attachment has stopped before the unit is
set down.
MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR
OF THE EMISSION CONTROL DEVICES AND
SYSTEMS MAY BE PERFORMED BY ANY NON-
ROAD ENGINE REPAIR ESTABLISHMENT OR
INDIVIDUAL.
Carburetor adjustment (Fig. 18)
Fig. 18
The carburetor is a precision part that mixes air and
fuel, and it is designed to ensure high performance
from the engine. Before the tool is shipped from
the factory, its carburetor is adjusted during a
test run. Only make adjustments if it is necessary
because of environmental conditions (the climate or
atmospheric pressure), the type of fuel, the type of
two-cycle oil, etc.
13
English
WARNING
● Because the carburetor is manufactured
with a high degree of precision, do not
disassemble it.
● For this product, the only setting of the
carburetor that can be adjusted is the idle
speed (T).
● Never start the engine without the complete
clutch cover and tube assembled! Otherwise
the clutch can come loose and cause
personal injuries.
T = Idle speed adjustment screw.

Cleaning the air fi lter
Open the air fi lter cover and remove the air fi lter
(13). Clean it.
Check that the fi lter is dry before reassembly.
An air fi lter that has been used for some time cannot
be cleaned completely. Therefore, it must regularly
be replaced with a new one. A damaged fi lter must
always be replaced.
NOTE
To put the air fi lter cover back into place, hook it
on the upper tabs and then attach it.
Fuel fi lter (Fig. 20)
Remove the fuel fi lter (14) from the fuel tank, and
replace it if it is dirty.
NOTE
A blocked fuel fi lter (14) can prevent the supply of
fuel and cause a rotation malfunction of the engine.

Spark plug (Fig. 21)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi lter
○ Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting diffi culties. If the engine is low on power,

Gear case (Fig. 23)
Check gear case or angle gear for grease level
about every 50 hours of operation by removing the
grease fi ller plug on the side of gear case.
If no grease can be seen on the fl anks of the
gears, fi ll the gear case with quality lithium based
multipurpose grease up to 3/4. Do not completely fi ll
the gear case.

its own side of the partition. (Fig. 25)
diffi cult to start or runs poorly at idling speed, always
check the spark plug fi rst. If the spark plug is dirty,
clean it and check the electrode gap. Re-adjust
if necessary. The correct gap is 0.024˝ (0.6 mm).
The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly
eroded.
