Always use branded 89 octane unleaded gasoline.
○
Use genuine two-cycle oil or use a mix between 25:1 to 50:1,
please consult the oil bottle for the ratio or Tanaka dealer.
○
If genuine 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.
○
Never use multi-grade oil (10 W/30) or waste oil.
○
Always mix fuel and oil in a separate clean container.
Always start by
fi
ling half the amount of fuel, which is to be used.
Then add the whole amount of oil. Mix (shake) the fuel mixture. Add

the engine before refueling.
○
Slowly open the fuel tank, when
fi
lling up with fuel, so that
possible over-pressure disappears.
○
Tighten the fuel cap carefully, after fueling.
○
Always move the unit at least 3 m from the fueling area before
starting.
○
Always wash any spilled fuel from clothing immediately with
soap.
○
Be sure to check for any fuel leakage after refueling.
Before fueling, clean the tank cap area carefully, to ensure that no
dirt falls into the tank. Make sure that the fuel is well mixed by shaking
the container, before fueling.

bottom, (
Fig. 14
)
ADJUSTMENT OF CHAIN OIL SUPPLY
The chain oil quantity discharged through the lubrication system is
factory-adjusted to the standard. Adjust the quantity in accordance
with the operating condition. The numbered label (26) describes
order of chain oil adjustment. (

○
Do not try to turn the screw (28) clockwise beyond 1 turn from
its most counter-clockwise position or the maximum quantity
discharged position.
○
After adjustment has been made, tighten
fi
xing screw (27).
(
