Fueling
(Do Not Smoke!)
This product is powered by a 2-cycle engine and requires pre-mixing
gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-cycle
35
engine oil in a clean container approved for gasoline (Fig. 35).
RECOMMENDED FUEL: THIS ENGINE IS CERTIFIED TO
OPERATE ON UNLEADED GASOLINE INTENDED FOR
AUTOMOTIVE USE WITH AN OCTANE RATING OF 89 ([R + M] / 2)
OR HIGHER (Fig. 36).
Mix 2-Cycle Engine Oil with gasoline according to the instructions
on the package. We strongly recommend the use of 2% (1:50)
Efco Two Cycle Engine Oil, which is specifically formulated for all
Efco air-cooled two-stroke engines.
The correct oil / fuel proportions shown in the table below are
suitable when using the Efco Two Cycle Engine Oil or an
equivalent high-quality engine oil (JASO specification FD or ISO
specification L-EGD). When oil specifications are NOT equivalent
36
or unknown use 4% (1:25) oil / fuel mixing ratio.
CAUTION: DO NOT USE AUTOMOTIVE OIL OR
2-CYCLE OUTBOARD OIL.
CAUTION: Never use a fuel with an alcohol percentage
higher than 10%; gasohol up to 10% alcohol or E10
fuel are acceptable.
When using an Oxygenated Gasoline a good practice of Fuel
Management is necessary.
Gasoline Oxygenated with alcohol readily takes/up water when it
37
is present; the water may be condensed out of humid air or be a
contaminant in the fuel system, including tank.
CAUTION:
- Match your fuel purchases to your consumption;
don't buy more than you will use in one or two
months;
- Store gasoline in a tightly-closed container in a
cool, dry place.
The use of Oxygenated Gasoline may cause the occurrence of
vapor-lock easier.
NOTE: 2-Cycle Engine Oil contains a fuel stabilizer and will stay
fresh up to 30 days. DO NOT mix quantities larger than usable in
a 30 day period. A 2-cycle oil containing a fuel stabilizer is
recommended.
