■ 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 refuel-
ing 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 en-
gine 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 funda-
mental engine parameters and components (eq.,
carburation, ignition timing and port timing) with-
out addition of any major hardware or the introduc-
tion 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 pre-
scribed, there is a danger that the engine tempera-
ture 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.
4. Pour in the rest of gasoline and agitate again for at least
one minute. As some oils may be difficult to agitate de-
pending on oil ingredients, sufficient agitation is neces-
4. Adjust the chain tension by turning the tensioner screw until
the tie straps just touch the bottom side of the bar rail.
(1) Chain tension adjusting screw
(a) Loosen (b) Tighten
5. Tighten the mounting nut securely with the bar tip held up
(TORQUE: 8.9 ~ 11.7 N.m./90 ~ 120 kg-cm). Then check
the chain for smooth rotation and correct tension while mov-
ing it by hand. If necessary, readjust.
(1) Tighten
WARNING
It is very important to maintain the proper chain tension.
Rapid wear of the guide bar or the chain coming off eas-
ily can be caused by improper tension. Especially when
using a new chain, take good care of it since it should
expand when first used.
BALANCE UNIT
1. Put on strap and attach unit to strap.
2. Depending on the working posture, slide clamp up or down
until unit balances and the strap fits your body.
6. Set up 7. Fuel and chain oil
