Understanding Safety Labels
State and Local Requirements
Your engine is equipped with a temperature limiting muffler, a spark arresting screen in order to comply
with the requirements of SAE Recommended Practice J335 and California Codes 4442 and 4443. All
national forest land and land managed by the states of California, Maine, Washington, Idaho,
Minnesota, New Jersey and Oregon require internal combustion engines to be equipped with a
spark arrester screen by law. Other states and federal agencies are enacting similar regulations.
If you operate a blower in a state or locale where such regulations exist, you are legally responsible for
maintaining the operating condition of these parts. Failure to do so is a violation of a law. Spark arrester
maintenance is described in the Maintenance-Spark Arresting Muffler Section of the manual.
Note: When using a blower for logging purposes, refer to Code of Federal Regulations, Parts 1910
and 1928.
WARNING: The ignition system of your unit produces an electromagnetic field of a very
low intensity. This field may interfere with some pacemakers. To reduce the risk of serious
or fatal injury, persons with pacemaker should consult their physician and the pacemaker
manufacturer before operating this tool.
WARNING: Muffler surfaces are very hot during and after operation of the blower, keep all
body parts away from the muffler. Serious burns may occur if contact is made with the
muffler.

SAFETY RULES
Basic Safety Precautions
• Read this manual carefully until you completely understand
and can follow all safety rules, precautions, and operating
instructions before attempting to use the unit.
• Restrict the use of your blower to adult users who understand
and can follow safety rules, precautions, and operating
instructions found in this manual. Minors should never be
allowed to use a blower.
• Do not handle or operate a blower when you are fatigued, ill,
or upset, or if you have taken alcohol, drugs, or medication.
You must be in good physical condition and mentally alert.
Blower work is strenuous. If you have any condition that might
be aggravated by strenuous work, check with your doctor
before operating a blower (Fig. 1). Be more cautious before
rest periods and towards the end of your shift.
• Keep children, bystanders, and animals a minimum of 35 feet
(10 meters) away from the work area. Do not allow other
people or animals to be near the blower when starting or
operating the blower (Fig. 2).
• While working with the blower, always use safety protective
approved clothing. The use of protective clothing does not
eliminate injury risks, but reduces the injury effects in case of
accident. Consult your trusted supplier to choose equipment in
compliance with legislation. The clothing must be proper and
not an obstacle. Wear adherent protective clothing. Protective
jackets (Fig.3) and dungarees (Fig.3) are ideal. Do not wear
clothes, scarves, ties or bracelets that get stuck in wood or
twigs. Tie up and protect long hair (example with foulards, cap,
helmets, etc.). Wear safety boots having skid-proof sole
and anti-piercing insert (Fig.4). Wear protective goggles
or face screens (Fig.5). Use protections against noises: for
example noise reduction ear guards (Fig.4) or earplugs.
The use of protections for the ear is very important, because
the perception of danger audio signals (screaming, alarms,
etc.) is limited. Always remove your hearing protection as
soon as the engine stop. Wear gloves (Fig.6, page 8) that
permit the maximum absorption of vibrations.
WARNING – Wear face mask when operating the
blower in dusty environments.
• Only loan your blower to expert users who are completely
familiar with blower operation and correct use. Give other
users the manual with operating instructions, which they have
to read before using the blower.
• Check the blower each day to ensure that each device,
whether for safety or otherwise, is functional.
• Never use a damaged, modified, or improperly repaired or
assembled blower. Do not remove, damage or deactivate any
of the safety devices.
• Carefully plan your blowing operation in advance. Do not start
blowing until you have a clear work area, secure footing.
• All blower service, other than the operations shown in the present
manual, have to be performed by competent personnel.
• It is unadvisable to hitch tools or applications to the P.t.o. that
are not specified by the manufacturer.
WARNING - The blower may throw objects at high
velocity that can ricochet and hit the operator. This may
cause serious eye damage. Always wear eye protection.

OPERATION
Fueling (Do Not Smoke!) (Fig. 21)
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. 19).
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. 20).
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.

blowers. Do not use very early in the morning or very late in
the day.
• Check wind direction and intensity. Never point the nozzle or
blow debris toward people, pets, cars or houses.
• Do not blow debris toward open windows or doors.
• Always be considerate of people passing by and of property.
• Do not leave the blower running when unattended.
• Do not use a blower to spread or mist fertilizers, chemicals
or other toxic substances, fuel, unless it is designed for these
purposes and in an appropriate area.
• Use the lowest possible throttle speed to do the job (Fig.26).
• Avoid using more than one machine at a time, especially
in neighborhoods or around buildings where sound can be
intensified.
Reducing dust (Fig.27)
• Pay attention to what you are moving.
• Practice moving grass clippings or a paper cup without moving
dust.
• Wet dusty areas down first before using a blower.
• Never use a leaf blower to move excessively dusty materials.
• A leaf blower should NOT be used to clean up:
— Large amounts of gravel or gravel dust
— Construction dirt
— Plaster dust
— Cement and concrete dust
— Dry garden topsoil
WARNING!– Dust with silica in its composition may
contain crystalline silica. Silica is a basic component
of sand, quartz, brick, clay, granite and numerous
other materials and rock, including masonry and
concrete products. Repeated and / or substantial
inhalation of airborne crystalline silica can cause
serious or fatal respiratory disease, including
silicosis. In addition, the state of California and some
other authorities have listed respirable crystalline
silica as a substance known to cause cancer. When
encountering such materials, always follow the
respiratory precautions mentioned above.
WARNING!– Breathing asbestos dust is dangerous
and can cause severe or fatal injury, respiratory
illness or cancer. The use and disposal of asbestos
containing products have been strictly regulated by
OSHA and the Environmental Protection Agency. Do
not blow or disturb asbestos or asbestos containing
product, such as asbestos insulation. If you have
any reason to believe that you might be disturbing
asbestos, immediately contact your employer or
local OSHA representative.
If the substance being blown is a commercial substance, review
the material safety data sheet for that substance or consult the
material manufacturer.

OPERATION
To blow away debris on the ground
WARNING! - When fitting the blower tube and nozzle,
the engine must be switched off and the stop switch
must be in the stop position.
The speed of the air jet is regulated by means of the throttle (A, Fig.28).
Select the speed which is best suited for the application. Once
the setting is identified, the throttle limiter (B, Fig.28) can be used
to maintain and retrieve it accurately.
Full throttle is obtained when the limiter (B) is pushed fully up.
Blowing
The blower is designed to be used with one hand only and can
be held in either the left or right hand.
The blower is equally suitable for use on uneven ground (e.g.
grassy areas) and flat areas covered in sawdust, leaves, grass
cuttings and similar material.
On flat surfaces, a more efficient blowing action will be obtained
using the “duckbill” tube p/n 56552002, which can be purchased
separately. This tube generates a broad and powerful stream of
air at ground level, which can be directed and controlled more
accurately than with the standard nozzle.
The throttle stop (B, Fig. 28) is used to set different engine
speeds and consequently to adjust the air jet. Before switching
off the engine, move the throttle stop to the minimum position.
WARNING – Constantly check the area in which you

OPERATION
NOTE - STARTING WARM ENGINE:
Follow above starting instructions, but do not use the Close
Choke position for start up again. To set fast idle for warm
engine starting, pull choke out completely and push back in
to the original Open Choke Position.
WARNING: Weather conditions and altitude may
affect carburetion. Do not allow bystanders close to
the blower while adjusting the carburetor.
Breaking-in the Engine
The engine reaches the maximum power after 5-8 hours of
activity.
Difficult Starting (or starting a flooded engine)
The engine may be flooded with too much fuel if it has not started
after 10 pulls. Flooded engines can be cleared of excess fuel
by following the warm engine starting procedure listed above.
Ensure the ON/STOP switch is in the ON position. Starting could
require pulling the starter rope handle many times depending on
how badly the unit is flooded. If engine fails to start refer to the
TROUBLE SHOOTING TABLE (page 21).
Engine is Flooded
If you did not move the choke lever to warm start quickly enough
after the engine began to fire, the combustion chamber is
flooded.
• Set the on/off swich to STOP.
• Engage a suitable tool in the spark plug boot (Fig. 40).
• Pry off the spark plug boot.
• Unscrew and dry off the spark plug.
• Open the throttle wide.
• Pull the starter rope several times to clear the combustion
chamber.
• Refit the spark plug and connect the spark plug boot, press it
down firmly – reassemble the other parts.
• Set the on/off swich to I, the starting position.
• Set the choke lever to warm start – even if engine is cold.
• Now start the engine.
Stopping The Engine
Move the throttle trigger (B, Fig.41) and the limiter (C) to the
minimum positions. Switch off the engine by moving the switch
(A) to the STOP position.

MAINTENANCE
Idle Speed Adjustment
Before adjusting the carburetor, clean the air filter as shown
Fig. 42, refer Maintenance-Air Filter Sections for details. Allow the engine to
warm up prior to carburetor adjustment.
This engine is designed and manufactured in order to comply with EPA
(Environmental Protection Agency) Phase 2 regulations.
The carburetor is factory set and should not require adjusting.
The carburetor will permit only limited adjustment of the “T” screw (Fig. 43).
WARNING: Don't modify the carburetor in any way in
such case the engine will not run in compliance with
emissions regulations.
• If the engine starts, runs, and accelerates but will not idle; turn the
idle speed screw “T” clockwise to increase idle speed (Fig. 43).
Fuel Filter
Check the fuel filter (C, Fig. 44) periodically. Replace it if
contaminated or damaged.
Air Filter
WARNING: Do not clean filter in gasoline or other
flammable solvent to avoid creating a fire hazard or
producing harmful evaporative emissions.
Every 8-10 operating hours, open the cover (A, Fig. 45) and
remove the filter (B). Wash with water and blow at a distance with
compressed air (Fig.46). A used air filter can never be completely
cleaned. It is advisable to replace your air filter with a new one
after six month of operation. Make sure the cover and the support
are clean before fitting the new filter.
CAUTION: Never run the engine without the air filter,
serious damage could result.
Make sure the air filter is correctly placed in the
air filter cover before reassembly. Always replace
damaged filters. Do not clean a filter with a brush.
Starter Unit
WARNING: The coil spring is under tension and
could fly apart causing serious injuries. Never try to
disassembly or modify it.
Engine
Clean the cylinder fins with compressed air or a brush
periodically. Dangerous overheating of engine may occur due to
impurities on the cylinder.
WARNING: Never run the blower without all the 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-7Y or NGK BPMR6A with .02” (0.5
mm) electrode gap (Fig. 47). 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 blower is provided with a Spark Arrester System p.n. 8856560020A
(Fig. 49) 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.49) 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.48) securing the deflector.
• Remove the deflector (B, Fig.49) , 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. 56560021AR).
• Reassemble the components removed previously, in reverse order, and
tighten the screws (A, Fig.49) torquing to 0.5 kgm (4.9 Nm).
WARNING – Do not use the blower 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.
Safety guard
Check that the spring (D, Fig.50) and the catch (E, Fig.51) are in perfect
working order. These components ensure that the safety guard is properly
closed.
