18.When replacing cutting attachment or other  
components, be sure to use the parts  
supplied or recommended by KOMATSU  
ZENOAH.  
19.When the unit is turned off, make sure the  
cutting attachment has stopped before the  
unit is set down.  
20.For units equipped with a clutch, be sure  
the cutting attachment stops turning when  
the engine idles.  
21.Use only for tasks explained in the  
instruction handbook.  
22.Discard blades that are bent, warped,  
cracked, broken or damaged in any way.  
23.Instructions on stopping a coasting blade.  
A blade can injure while it continues to spin  
after the engine is stopped or throttle control  
is released.  
24.Stop the engine and blade before removing  
material that is blocking or entangling the  
cutting attachment.  
25.Use a sharp blade. A dull blade is more  
likely to snag and thrust. Replace the  
fastening nut according to the  
manufacturer's instruction.  
26.Cut only material recommended by the  
manufacturer. Do not let the blade contact  
material it cannot cut, such as rocks, metal  
etc.  
avoid any accident by hitting hidden  
obstacles such as stumps, stones, cans, or  
broken grass.  
11.Keep bystanders and animals at least 15  
meters away from the operating point, If you  
are approached, immediately stop the  
engine.  
12.Keep firm footholds and balance at all  
times. Do not use the unit where footing is  
unsteady or slippery.  
13.Keep cutting attachment below waist level.  
14.Keep all parts of your body away from the  
rotating cutting attachment and hot  
surfaces.  
15.Warn the operator of the danger of blade  
thrust. (Kick back)  
2. Do not operate this tool when you are tired,  
ill, or under the influence of alchohol, drugs,  
or medication.  
3. Always wear eye or face protection and  
hearing protection.  
4. Do not wear loose clothing, jewelry, short  
trousers, sandals, or go barefoot. Do not  
wear anything which might be caught by  
branches or moving part of the unit. Secure  
hair so it is above shoulder length.  
5. Never start or run the engine inside a  
closed room or building. Exhaust gases  
contain dangerous carbon monoxide.  
6. Before starting the engine, inspect the  
entire unit for loose fasteners and fuel  
leakage. Make sure that the cutting  
attachment is properly installed and  
securely fastened.  
7. Be sure the blade guard is attached in  
place.  
8. Fuel is highly flammable. Always keep open  
flames and sparks away from the unit and  
fuel depot. Do not smoke while refueling the  
unit or mixing fuel.  
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.  
16.When inspecting or servicing the unit, make  
sure to stop the engine and disconnect the  
spark plug as necessary.  
17.Cover the blade when the transporting or  
storing the unit. Secure the unit before for

TRIMMING GRASS AND WEEDS  
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.

6. While holding the unit firmly, pull out the  
starter rope quickly until engine fires.  
1. Hold the unit so the head is off the ground  
and is tilted about 20 degrees toward the  
sweep direction.  
2. Use full throttle when cutting.  
3. You can avoid thrown debris by sweeping  
from your left to the right.  
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.  
7. Take precautions to avoid wire, grass and  
dead, dry, long-stem weeds from wrapping  
around the head shaft. Such materials can  
stall the head and cause the clutch to slip,  
resulting in damage to the clutch system if  
repeated frequently.

FUEL FILTER  
When the engine runs short of fuel supply,  
check the fuel cap and the fuel filter for  
blockage.  
WARNING  
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.

ADJUSTING THE LINE LENGTH  
SPARK PLUG  
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.  
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 KOMATSU  
ZENOAH.  
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.  
IMPORTANT  
Avoid pulling the rope to its end or returning  
it by releasing the knob. Such actions can  
cause starter failures.  
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.

1. Feed fuel into the fuel tank and tighten the  
cap securely.  
2. 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.  
Note that using any spark plug other than  
those designated may result in the engine  
failing to operate properly or in the engine  
becoming overheated and damaged.

WARNING  
WARNING  
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 order to be able to view the upper  
part of the cylinder.  
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.  
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.  
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.  
1. For replacement line, use a diameter of 2.4  
mm. The spool is capable for a line upto 6 m  
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  
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.  
(1) Intake air  
cooling vent  
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  
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.
