OPERATION
Bucking Spike
WARNING: Your chainsaw 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
34
other standards. 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
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
35
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 or unknown use 4% (1:25) oil / fuel mixing ratio.
CAUTION: DO NOT USE AUTOMOTIVE OIL OR
2-CYCLE OUTBOARD OIL.
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
36
cool, dry place.
CAUTION - For the mixture, never use a fuel with
an ethanol percentage higher than 10%; gasohol
(mixture of gasoline and ethanol) up to 10% ethanol
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.
The use of Oxygenated Gasoline may cause the occurrence of
vapor-lock easier.
37
NOTE - Prepare only the quantity of mixture required for
immediate use; do not leave fuel in the tank or a container for a
long time. Were commend the use of the additive Emak ADDITIX
2000 code 001000972 if the mixture is to be stored for 30 days.
Alkylate gasoline
CAUTIONS – Alkylate fuels have different density
than normal fuel. Therefore engines, set with
normal fuel, need different H jet regulation to avoid
critical issues. For this operation it's necessary
turned at a Licensed Service Dealer.
