OPERATION
Fueling (Do Not Smoke!) (Fig. 18)
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. 16).
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. 17).
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 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.

parts, including starting housing, securely in place.
Because parts can fracture and pose a danger of
thrown objects, leave repairs to the fan to trained
Servicing Dealers.
Spark Plug
This engine uses a Champion RCJ-4 with .02” (0.5 mm) electrode
gap (Fig. 35). Use an exact replacement and replace every six
months or more frequently, if necessary.

MAINTENANCE
WARNING: Never test the ignition system with ignition
wire connector removed from spark plug or with
unseated spark plug, since uncontained sparking
may cause a fire. A loose connection between spark
plug terminal and ignition wire connector in the boot
may create arcing that could ignite combustible
fumes and cause a fire.
Use only resistor type spark plugs of the approved range.
Factors such as:
- too much oil in fuel mix;
- dirty air filter;
- unfavourable running conditions, e.g. operating at part load;
may result in rapid deterioration of the spark plug.
Spark Arresting Muffler
The water pump is provided with a Spark Arrester System p.n.
8856560020A (Fig. 37) complying with the requirements of SAE
J335 standard; you can check the p.n. of the Spark Arrester
System on the muffler itself.
WARNING – This muffler incorporates a catalytic
converter, needed in order to ensure the engine
complies with current emissions standards. Never
attempt to modify or remove the catalytic converter:
in doing so, you will be breaking the law.
WARNING – Mufflers with catalytic converters
become very hot during operation, and retain heat
for a long time after the engine has been stopped.
This is the case even with the engine idling. Contact
can burn the skin. Always remember the potential
fire risk!
CAUTION – If the catalytic converter is damaged, it
must be replaced. If the catalytic converter frequently
becomes blocked, this could be an indication that
the efficiency of the muffler is limited.
Spark arrester screen
As the spark arrester screen (D, Fig.37) can become dirty during
normal use, it should be inspected weekly and cleaned as
required. In particular:
- check the spark arrester screen periodically, and replace it if
holed, bent or buckled;
- check carefully for any dust, debris or organic material that may
be in contact with parts of the spark arrester system; clean
regularly using tools or compressed air.
Cleaning:
• Allow the muffler to cool.
• Remove the two screws (A, Fig.36) securing the deflector.
• Remove the deflector (B, Fig.37), the gasket (C) and the spark
arrester screen (D).
• Clean and inspect the spark arrester screen.
WARNING – Replace the spark arrester screen if
damaged, faulty or worn (p.n. 56550143R).
• Reassemble the components removed previously, in reverse
order, and tighten the screws (A, Fig.37) torquing to 0.5 kgm
(4.9 Nm).
WARNING – Do not use the water pump if the muffler
is damaged or missing, or has been altered in any
way. Operating the machine with an improperly
maintained muffler will increase the risk of fire and
hearing loss.
