pipe and fix it with 2 screws.
■
INSTALLING CUTTING HEAD
1. While locking the gear shaft, by inserting
the supplied tool into the upper holder on
the gearbox, loosen and remove the

Operation
■
BALANCE UNIT
1. Put on strap and attach unit to strap.
2. Slide clamp up or down until unit balances
with head aparting from the ground when
using it.
• 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 3m (10ft) away from the fueling point
before starting the engine.
WARNING!!
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 10feet (3meters) 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 period 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 lot 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 fhe mixed gasoline, etc. described
therein, if may not be covered by the warranty.
NOTE
WARNING!!
• The Komatsu Zenoah engines are lubricated by
oil specially formulated for air-cooled 2-cycle
gasoline engine use. If Komatsu 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
• 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 89 RON (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.
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.
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

ADJUSTMENTS
•
THROTTLE CABLE: The normal play is 1 or
2 mm when measured at the carburetor
side end. Readjust with the cable adjuster
as required.
•
ENGINE IDLLING SPEED: When the
engine tends to stop frequently at idling
mode, turn the adjusting screw clockwise.
When the cutting head keeps rotating after
releasing the trigger, turn the adjusting
screw counter-clockwise.
•
Warm up the engine before adjusting the
idling speed.
