3. When refilling the tank, always
turn off the engine and allow it to
cool down. Take a careful look
around to make sure that there are
no sparks or open flames anywhere nearby before refueling.
4. Wipe spilled fuel completely using a dry rag if any fuel spillage
occurs during refueling.
5. After refueling, screw the fuel cap
back tightly onto the fuel tank and
then carry the unit to a spot 3 m
or more away from where it was
refueled before turning on the
engine.
6. Do not inhale fuel fumes as they
are toxic.
TRANSPORTATION
1. When hand-carrying the product,
cover over the cutting part if necessary, lift up the product and
carry it paying attention to the

6. Fuel
eHT752S / eHT602D
■ FUEL
• 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
• Pay attention to agitation.
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.
1. Select 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.
GASOHOL – It can cause deterioration of rubber and/
2.
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 aperiod 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.
• As for details of quality assurance, read the description in the section Limited Warranty carefully. Moreover, normal wear and change in product with no
functional influence are not covered by the warranty.
Also, be careful that, if the usage in the instruction
manual is not observed as to the mixed gasoline,
etc. described therein, it may not be covered by the
warranty.
G
B
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.

CUTTING WORK
WARNING
eHT752S / eHT602D
• Weather conditions and altitude may effect
carburation.
• Do not allow anyone to stay close to the hedge-
trimmer while working or while adjusting the carburetor.
HOW TO USE : HANDLE (eHT602D)
• To reduce fatigue when trimming hedges, the handle
can be swivelled through 90° to the left or right.
• Do not press the throttle during this operation!
Proceed as follows:
1. Free the handle by pressing the locking lever.
2. Turn the handle until the locking lever clicks into place.
3. When the handle is locked in its new position, you can
apply the throttle again.
(1) handle
(2) locking lever
• You can swivel the handle even with the engine
idling because the hedge-trimmer is equipped with
a blade brake that maintains the blades at a
standstill.
■ HEDGE TRIMMING TECHNIQUES
Trim sides of a hedge first, and then the top.
Vertical cut:
•With the single-sided blade hedge-trimmer, model
eHT752S always cut from the bottom up.
G
B
Horizontal cut:
• In order to get the best cutting results, slightly tilt the
blade (5÷10°) towards the cutting direction.
Cut slowly, specially with thick hedges.
WARNING
Always follow the safety precautions.
The hedge-trimmer must only be used to trim hedges
or small bushes. It is forbidden to cut other types of
material. Do not use the hedge-trimmer as a lever to
lift, move or break objects, nor lock it on fixed supports. It is forbidden to apply tools or applications
that are not the ones indicated by the manufacturer
onto the hedge-trimmer’s power take-off. Do not use
it for pruning trees or cutting grass.
• Use only as much throttle as is needed to do the job.
Excessive engine speed is unnecessary.
• Avoid cutting thick branches, for which will damage
the blades and shorten the life of drive systems.
• Tilting the trimmer 5 to 10° to the cutting object will
make the job easy and bring a good result.
• Always keep your body to the carburetor side of your
trimmer, never on the muffler side.
• When a new machine is first operated, in the first few
minutes grease may come out of the gear case. But,
since this is excess grease, there is no cause for alarm.
Just wipe it off with the engine stopped for next use.
• 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.
•With the 2-sided blade model eHT602D use an arcing cut from the bottom upwards, then downwards to
use both sides of the blades.
