OPERATION
Bucking Spike
WARNING: Your chain saw is fitted with a bucking
spike (A, Fig. 34). The bucking spike is very sharp
and can cause injury. Be extremely careful when
working near the bucking spike.
WARNING: Removal of the bucking spike will violate
the saws compliance of SAE J335 and other stan-
dards. See Safety-State and Local Requirements.
Fueling (Do Not Smoke!) (Fig. 37)
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 engine oil in a clean container approved for gasoline (Fig.
35).
RECOMMENDED
FUEL: THIS ENGINE IS CERTIFIED TO OPE-
RATE ON UNLEADED GASOLINE INTENDED FOR AUTOMOTI-
VE 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 sui-
table when using the Efco Two Cycle Engine Oil or an equivalent
high-quality engine oil (JASO specification FD or ISO specifi-
cation L-EGD). When oil specifications are NOT equivalent 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
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.
