Blade thrust may occur when the spinning
blade contacts a solid object in the critical
area. A dangerous reaction may occur causing
the entire unit and operator to be thrust
violently. This reaction is called Kick back. As a
result, the operator can lose control of the unit
which can cause serious or fatal injury. Kick
back is more likely to occur in areas where it is
difficult to see the material to be cut.

ADJUSTING THE LINE LENGTH
(1)
•
Your brushcutters is equipped with a semi- auto
type nylon line head that allows the operator to
advance the line without stopping the engine.
When the line becomes short, lightly tap the
head on the ground while running the engine at
full throttle.
Each time the head is bumped, the line
advance about 1 inch(25.4 mm). For better
effect, tap the head on bear ground or hard soil.
Avoid bumping in thick, tall grass as the engine
may stall by overload.

Maintenance
WARNING
(1) Idle adjusting screw
Make sure that the engine has stopped and is
cool before performing any service to the
machine. Contact with moving cutting head or
hot muffler may result in a personal injury.
NOTE
WARNING
Warm up the engine before adjusting the idling
speed.
The product is equipped with a centrifugal
clutch mechanism, so the cutting attachment
begins to rotate as soon as the engine is
started by putting the throttle into the start
position. When starting the engine, place the
product onto the ground in a flat clear area
and hold it firmly in place so as to ensure that
neither the cutting part nor the throttle come
into contact with any obstacle when the engine
starts.
■ CUTTING WORK
■ AIR FILTER
•
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.
The air filter, if clogged,
will reduce the engine
performance. Check and
clean the filter element in
warm, soapy water as
required. Dry completely
before installing. If the
element is broken or
shrunk, replace with a
new one.

•
Choose a suitable recommended cutting
attachment according to the object to be cut.
Never use other cutting attachment not
approved by ZENOAH.
■ FUEL FILTER
IMPORTANT
Avoid pulling the rope to its end or returning it by
releasing the knob. Such actions can cause starter
failures.
When the engine runs
short of fuel supply,
check the fuel cap and
the fuel filter for
blockage.
7. Move the choke lever downward to open the
choke. And restart engine.
8. Allow the engine to warm up for a several
minutes before starting operation.

■ SPARK PLUG
Starting failure and misfiring
are often caused by a fouled
spark plug. Clean the spark
plug and check that the plug
gap is in the correct range.
For a replacement plug, use
the correct type specified by
ZENOAH.
NOTE
1. When restarting the engine immediately after
stopping it, leave the choke open.
2. Overchoking can make the engine hard to start
due to excess fuel. When the engine failed to
start after several attempts, open the choke and
repeat pulling the rope, or remove the spark
plug and dry it.
■ LINE HEAD USAGE
0.6~0.7mm
WARNING
1. Always wear eye protection such as safety
goggles. Never lean over the rotating cutting
head. Rocks or other debris could be thrown
into eyes and face and cause serious
personal injury.
2. Keep the debris guard attached in place at
all times when the unit is operated.

first turn the plug until it is
2. Shift the stop switch to the STOP position.
TRIMMING GRASS AND WEEDS
(1)
•
Always remember that the TIP of the line does
cutting. You will achieve better results by not
crowding the line into the cutting area. Allow the
unit to trim at its own pace.
(1)
finger tight, then tighten it a
quarter turn more with a
socket wrench.
1. Hold the unit so the head is off the ground and
is tilted about 20 degrees toward the sweep
direction.
(1) Stop switch
Tightning torque: 9.8~11.8N.m. (1.0~1.2kgm))
2. Use full throttle when cutting.
IMPORTANT
Except for an emergency, avoid stopping the
engine while pulling the throttle lever.
3. You can avoid thrown debris by sweeping from
your left to the right.
■ REFILLING TRIMMING LINE
1. For replacement line, use a diameter of 2.4mm.
The spool is capable for a line upto 6m on the
4” head. Avoid using a larger line as it may cut
down the trimming performance.
2. Pinch the slotted area on the both sides of the
spool housing to unhook the bottom cap.
3. Take out the spool and pull off the old line. Put
one end of new line through the spool holes
and pull it until the length is equal between
each part of the line.
4. Wind up the line in the correct direction as
indicated on the spool.
5. Hook each end of the line in the slot on the
edge of the spool, and then put the ends
4. Use a slow, deliberate action to cut heavy
growth. The rate of cutting motion will depend
on the material being cut. Heavy growth will
require slower action than will light growth.
5. Never swing the unit so hard as you are in
danger of losing your balance or control of the
unit.
6. Try to control the cutting motion with the hip
rather than placing the full workload on the arm
and hands.
■ ADJUSTING THROTTLE CABLE
•
The normal play is 1 or 2 mm when measured
at the carburetor side end. Readjust with the
cable adjuster as required.
7. Take precautions to avoid wire, grass and
dead, dry, long-stem weeds from wrapping
around the head shaft. Such materials can stall

through the eyelets on the housing. Make sure
that the spring and the washers are in place.
6. While holding the spool against the housing,
pull the line ends to release them from the slot.
7. Line up the slot on the bottom cap with the hook
on the housing, press the cap against the
housing until it clicks.
■ IMUFFLER
WARNING
•
Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any
sign of exhaust leakage is found, stop using
the machine and have it repaired
immediately.
•
Note that failing to do so may result in the
engine catching on fire.
■ INTAKE AIR COOLING VENT
WARNING
■ PROCEDURES TO BE PERFORMED AFTER
EVERY 100 HOURS OF USE
1. Remove the muffler, insert a screwdriver into
the vent, and wipe away any carbon buildup.
Wipe away any carbon buildup on the muffler
exhaust vent and cylinder exhaust port at the
same time.
2. Tighten all screws, bolts, and fittings.
3. Check to see if any oil or grease has worked its
way in between the clutch lining and drum, and
if it has, wipe it away using oil-free, lead-free
gasoline.
•
Never touch the cylinder, muffler, or spark
plugs with your bare hands immediately
after stopping the engine. The engine can
become very hot when in operation, and
doing so could result in severe burns.
•
When checking the machine to make sure
that it is okay before using it, check the area
around the muffler and remove any wood
chips or leaves which have attached
themselves to the brushcutter. Failing to do
so could cause the muffler to become
overheated and that in turn could cause the
engine to catch on fire. Always make sure
that the muffler is clean and free of wood
chips, leaves, and other waste before use.
Check the intake air cooling vent and the
area around the cylinder cooling fins after
every 25 hours of use for blockage, and
remove any waste which has attached itself
to the brushcutter. Note that it is necessary
to remove the engine cover shown in in
order to be able to view the upper part of the
cylinder.
•
■ MAINTENANCE BEFORE STORAGE
•
Old fuel left in the carburetor may cause
starting failure. When a series of operation
finished, make sure to empty the fuel tank and
drain the carburetor.
•
Check all parts and the functions. If the failured
or damaged parts have been found, replace
them with new ones.
IMPORTANT
If waste gets stuck and causes blockage around
the intake air cooling vent or between the cylinder
fins, it may cause the engine to overheat, and that
in turn may cause mechanical failure on the part of
the brushcutter.
■ GEAR CASE
•
The reduction gears are lubricated by
multipurpose, lithium-based grease in the gear
case. Supply new grease every 25 hours of use
or more often depending on the job condition.
Remove the bolt opposit to the grease nipple
before installing new grease to arrange for old
grease to exit.
