■ FUEL

WARNING

• Gasoline is very flammable. Avoid smoking or
bringing any flame or sparks near fuel. Make sure
to stop the engine and allow it cool before refuel­ing the unit. Select outdoor bare ground for fueling
and move at least 3 m (10 ft) away from the fueling
point before starting the engine.

• The Zenoah engines are lubricated by oil specially
formulated for air-cooled 2-cycle gasoline engine use.
If Zenoah oil is not available, use an anti-oxidant added
quality oil expressly labeled for air-cooled 2-cycle en­gine use (JASO FC GRADE OIL or ISO EGC GRADE).

• Do not use BIA or TCW (2-stroke water-cooling type)
mixed oil.

■ RECOMMENDED MIXING RATIO

GASOLINE 50 : OIL 1

(when using ZENOAH genuine oil)

• Exhaust emission are controlled by the funda­mental engine parameters and components (eq.,
carburation, ignition timing and port timing) with­out addition of any major hardware or the introduc­tion of an inert material during combustion.

• These engines are certified to operate on unleaded
gasoline.

• Make sure to use gasoline with a minimum octane
number of 89RON (USA/Canada: 87AL).

• If you use a gasoline of a lower octane value than pre­scribed, there is a danger that the engine tempera­ture may rise and an engine problem such as piston
seizing may consequently occur.

• Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health and
the environment.

• Poor quality gasolines or oils may damage sealing
rings, fuel lines or fuel tank of the engine.

■ HOW TO MIX FUEL

WARNING

• Pay attention to agitation.

1. Measure out the quantities of gasoline and oil to be

mixed.

2. Put some of the gasoline into a clean, approved fuel

container.

3. Pour in all of the oil and agitate well.

GB-14

EXZ2600DL

7. Fuel and chain oil

4. Pour in the rest of gasoline and agitate again for at
least one minute. As some oils may be difficult to
agitate depending on oil ingredients, sufficient agi­tation is necessary for the engine to last long. Be
careful that, if the agitation is insufficient, there is an
increased danger of early piston seizing due to ab­normally lean mixture.

5.

Put a clear indication on the outside of the container
to avoid mixing up with gasoline or other containers.

6. Indicate the contents on outside of container for easy
identification.

■ FUELING THE UNIT

1. Untwist and remove the fuel cap. Rest the cap on a
dustless place.

2. Put fuel into the fuel tank to 80% of the full capacity.

3. Fasten the fuel cap securely and wipe up any fuel
spillage around the unit.

WARNING

1. Select flat and bare ground for fueling.

2. Move at least 10 feet (3 meters) away from the fu­eling point before starting the engine.

3. Stop the engine before refueling the unit. At that
time, be sure to sufficiently agitate the mixed gaso­line in the container.

■ FOR YOUR ENGINE LIFE, AVOID:

1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause
severe damage to the internal engine parts very quickly.

2. GASOHOL – It can cause deterioration of rubber and/
or plastic parts and disruption of engine lubrication.

3. OIL FOR 4-CYCLE ENGINE USE – It can cause spark
plug fouling, exhaust port blocking, or piston ring stick­ing.

4. Mixed fuels which have been left unused for a pe-
riod of one month or more may clog the carburetor
and result in the engine failing to operate properly.

5. In the case of storing the product for a long period of
time, clean the fuel tank after rendering it empty. Next,
activate the engine and empty the carburetor of the
composite fuel.

6. In the case of scrapping the used mixed oil container,
scrap it only at an authorized repository site.

CUTTING WORK (LINE HEAD USAGE)

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 in place at all times when
the unit is operated.

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.

1. Hold the unit so the head is off the ground and is tilted
about 20 degrees toward the sweep direction.

ADJUSTING THE LINE LENGTH

•Your brush cutters are 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 advances
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.

2. You can avoid thrown debris by sweeping from your
left to the right.

3. 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.

4. Never swing the unit so hard as you are in danger of
losing your balance or control of the unit.

5. Tr y to control the cutting motion with the hip rather
than placing the full workload on the arm and hands.

6. 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.

STARTING THE ENGINE

Please refer to 5. For safe operation (P. 7 ~ 9), 8. Ope­ration (P. 15 ~ 17).

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 to ensure that neither
the cutting part nor the throttle come into contact
with any obstacle when the engine starts.

CUTTING METHOD

a) Use the front left side cutting.

b) Guide the blade from your right to left with it tilted

slightly to your left.

OPERATION

1. Check the bolt to fasten the blade and be sure the
bolt has no fault, and no abrasion.

2. Be sure that the blade and the holder have been fas­tened according to instruction and that the blade turns
smoothly without abnormal noise.

WARNING

• The rotating parts fastened incorrectly may cause
serious accident to the operator.

• Make sure that the blade is not bent, warped,
cracked, broken or damaged.

• If you find any error to the blade, discard it and
replace with a new one, which is certified by
ZENOAH.

c) When mowing a wide area, start working from your

left end to avoid interference of cut grass.

d) The blade may be seized by weeds if the engine

speed is too low, or the blade cuts too deep into
weeds. Adjust the engine speed and cutting depth
according to the condition of object.

WARNING

• If the grass or other object gets caught in the blade,

or if the unit starts to shake or vibrate, turn off the
engine and check the whole unit. Change the blade
if it has been damaged.

• Turn off the engine and make sure the blade has

completely stopped before checking the blade, and
removing any object got caught in.

WARNING

CONTROLLING BLADE BOUNCE

Blade thrust can cause serious personal injury. Care­fully study this section. It is important that you un­derstand what causes blade thrust, how you can re­duce the chance of blade thrust and how you can
remain in control of the unit if blade thrust does oc­cur.

1. What causes blade thrust:

• blade thrust can occur when the moving blade
contacts an object that it cannot cut. This contact
causes the blade to stop for an instant and then
suddenly move or “bounce” away from the object
that was hit. The operator can lose control of the
unit and the blade can cause serious personal
injury to the operator or any person nearby if the
blade contacts any part of the body.

2. How you can reduce the chance of blade thrust:
a. Recognize that blade thrust can happen. By un-

derstanding and knowing about bounce, you can
help eliminate the element of surprise.

b. Cut fibrous weeds and grass only. Do not let the

blade contact materials it cannot cut such as hard,
woody vines and bushes or rocks, fences, metal,
etc.

c. Be extra prepared for bounce if you must cut where

you cannot see the blade making contact such as
in areas of dense growth.

d. Keep the blade sharp. A dull blade increases the

chance of bounce.

e. Avoid feeding the blade too rapidly. The blade can

bounce away from material being cut if the blade

is fed faster than its cutting capability.
f. Cut only from your right to your left.
g. Keep your path of advance clear of material that

has been cut and other debris.

3. How you can maintain the best control:
a. Keep a good, firm grip on the unit with both hands.

A firm grip can help neutralize bounce. Keep your
right and left hands completely around the respec­tive handles.

b. Keep both feet spread apart in a comfortable

stance and yet braced for the possibility that the
unit could bounce. Do not overreach. Keep firm
footing and balance.

WARNING

This product is equipped with extremely sharp blades,
and when used improperly these blades can be ex­tremely dangerous and improper handling can cause
accidents, which may in turn lead to serious injury
or death. For this reason, you should always be care­ful to follow the following instructions when using
your trimmer.

• Never hold the trimmer in a way in which the blades
are pointed towards someone else.

• Never allow the blades to come into proximity with
your body while the engine of the trimmer is in opera­tion.

• Always be sure to turn off the engine before chang­ing the angle of the blades, removing branches which
have become stuck in the blades, or at any other time
when coming into close proximity with the blades.

•Always wear work gloves made of leather or some
other sturdy material when using the trimmer.

•Always place the blade cover provided with the trim­mer over the blades when not in use.

• Falling branches may fall onto the face or into the

eyes, resulting in injuries, scratches, and cuts, and
for this reason you should always be sure to wear
a helmet and face protector when using your trim­mer.

EXZ2600DL

Checking oil supply

After starting the engine, run the chain at medium speed
and see if chain oil has scattered off, as shown in the
figure.

(1) Chain oil

NOTE

The oil reservoir has a capacity sufficient to provide about
40 minutes of cutting time (when set to deliver the mini­mum flow rate, or about as long as you’ll get from a tank
of fuel). Be sure to refill the oil tank every time when refu­elling the saw.

Adjusting Oil Flow Rate

WARNING

Never fill the oil reservoir nor adjust the oiler with
the engine running.

IMPORTANT

An increase in bar oil flow rate will speed oil consump­tion, requiring more frequent checks on the oil reservoir.
To ensure sufficient lubrication, it may be necessary to
check the oil level more frequently than at fuel tank refills.

The guide bar and chain are lubricated automatically by
a pump that operates whenever the chain rotates. The
pump is set at the factory to deliver a minimum flow rate,
but it can be adjusted in the field. A temporary increase
in oil flow is often desirable when cutting things like hard­wood or wood with a lot of pitch.

Adjust the pump as follows:

1. Stop the engine and make sure the stop switch is in
the OFF position.

2. Place the unit on its side with the oil reservoir up.

(1) Oil tank (2) Chain cover

IMPORTANT

The oil flow adjusting screw must be pressed in slightly
in order to turn. Failure to do so could damage the
pump and screw.

3. With a screwdriver, push in on the oil flow rate adjust­ing screw and turn in the desired direction (there are
three incremental settings):

(a) Clockwise-decrease lubrication
(b) Counter clockwise-increase lubrication
(c) Middle

WARNING

• Always wear work gloves made of leather or some
other sturdy material when using the polesaw.

• Falling branches may fall onto the face or into the
eyes, resulting in injuries, scratches, and cuts, and
for this reason you should always be sure to wear
a helmet and face protector when using your
polesaw.

• Keep the blade guard and the mad guard attached

in place at all times when the unit is operated.

• Before starting a job, check the area and remove

all obstacles and objects that could be thrown by
the blade.

• Do not adjust the wheel height or try to remove

anything entangled to the blade with the engine
running.

1. Before starting the engine, adjust the wheel height
for desired cutting depth (see page 15).

2. Before starting a job, plan your direction of travel so
that you can always hold the edger on you right side
and can walk on a hard surface as much as possible.

3. When starting to edge, run the engine at full throttle,
and slowly have the blade cut into the edge groove.

INTAKE AIR COOLING VENT

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 (MA5) in order to be able to view the up­per part of the cylinder.

BLADES

• When refilling the tank or resting, it is often a good
idea to use the time to oil the cutting blades.

• If a gap exists between the upper and lower blades,
follow the procedure below to adjust them so that they
fit more closely together.

(1) Upper blade (2) Lower blade

1. Loosen lock nut (A) as shown in the diagram.

2. Tighten screw (B) fully, and then turn one-third to one­half of a rotation backward.

3. While holding onto the screw to keep it in position,
tighten the lock nut.

4. Check to make sure that the flat washer (C) is loose
enough so that it may be turned by pressing on it with
a finger.

NOTE

• 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 cutter holders before installing new
grease to arrange for old grease to exit.

Screwing in the screw too tightly may make it impossible
for the blades to move. Conversely, not screwing in the
screw tightly enough may make the blades of the trim­mer feel dull and cause leaves and branches to become
caught in the blades of the trimmer.

QUICK TIP

If the blades become so worn down that it is no longer possible
to eliminate the gap between them, you should contact the au­thorized ZENOAH servicing dealer from which you purchased
your ZENOAH trimmer to have the blades resharpened or re­placed.

GEAR CASE
