For safe operation  
1. Read this manual carefully until you  
completely understand and can follow all  
safety notes, precautions, and operating  
instructions before using of the unit.  
10.Check the condition of working area to  
18.When replacing cutting attachment or other  
components, be sure to use the parts  
supplied or recommended by 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.  
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.  
21.Use only for tasks explained in the  
instruction handbook.  
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.  
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.  
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  
27.Always wear safety boots, additionally a  
helmet is required if there is a risk of contact  
with falling objects.  
9. When refueling the unit, make sure to stop  
the engine and allow it to cool down. Wipe  
spilled fuel completely from the unit. Move

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.  
STARTING THE ENGINE

TRIMMING GRASS AND WEEDS  
2
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. 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.

Throttle cable: The normal play is 1 or 2 mm  
when measured at the carburetor side end.  
Readjust with the cable adjuster(1) as re-  
quired.  
Engine idling speed: It is normal that the  
engine keeps running without the blade  
rotation, when the throttle lever is released.  
When the engine speed is too high or too  
slow, readjust the idle set screw (2).  
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.

ADJUSTING THE LINE LENGTH  
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.  
BC2310LE  
BC530WE  
BC2610LE  
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.  
CUTTING WORK  
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.

REFILLING TRIMMING LINE  
BC3500LE  
2
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 and pull it until the length is equal  
between each part of the line.  
Choose a suitable recommended cutting  
attachment according to the object to be  
cut. Never use other cutting attachment not  
approved by ZENOAH.  
4. Place the unit on a flat, firm place. Keep the  
cutting head clear of everything around it.  
5. While holding the unit firmly, pull out the  
starter rope quickly.  
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.  
6. After the engine has started, open the  
choke guradually and allow the engine to  
warm up. Pull the throttle lever to unlock it.  
 
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.  
AIR FILTER  
A clogged air filter will reduce the engine  
performance. Check periodically 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.

Supply multi-purpose grease at every 25  
hours of use.  
1. Remove the cutter holders.  
2. Charge grease until waste grease appears  
around the gear shaft.  
FUEL FILTER  
When the engine runs short of fuel supply,  
check the fuel strainer for blockage.  
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.  
SPARK PLUG  
Starting failure and mis-firing are often  
caused by a fouled spark plug. Periodically  
clean the spark plug, and replace with a  
new one as required.  
Check all parts and the functions. If the  
failured or damaged parts have been found,  
replace them with new ones.
