7. Fuel

HB2302 / HBZ2601

■ 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 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 funda-

mental 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

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.

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 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.

9. Maintenance

FUEL FILTER

•A clogged fuel filter may cause poor acceleration of
the engine. Check periodically to see if the filter is
clogged with dirt. The filter can be taken out of the
fueling port using a small wire hook. Disconnect the
filter assembly from the fuel pipe and unhook the re­tainer to disassemble it. Clean the components with
gasoline.

SPARK PLUG

• The spark plug may gather carbon deposits on its
firing end with reasonable use. Remove and inspect
the spark plug every 25 hours and clean the elec­trodes as necessary with a wire brush. The spark gap
should be adjusted to .025 in (0.6~0.7mm).

• Note that failing to do so may result in the engine
catching on fire.

IMPORTANT

• Before starting operation, always make sure to check
if the muffler is properly held by three bolts to the cyl­inder. (Fastening Torque : 8~12 N·m)

• Even if one bolt out of three bolts is loose, the muffler
may get loose during operation which may result in
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.

• Plug manufacturers recommend replacing the plug
twice a year to avoid unexpected plug failure in a job.
