3. SAFETY RULES
State and Local Requirements
The engine is NOT equipped with a Spark Arrester
System complying 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.
Operating this engine in a state or locale where
such regulations apply, could result in a violation
of the law.
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.
WARNING: Exposure to vibrations
through prolonged use of gasoline
powered hand tools could cause blood
vessel or nerve damage in the fingers, hands,
and wrists of people prone to circulation
disorders or abnormal swellings. Prolonged
use in cold weather has been linked to blood
vessel damage in otherwise healthy people. If
symptoms occur such as numbness, pain, loss
of strength, change in skin color or texture, or
loss of feeling in the fingers, hands, or wrists,
discontinue the use of this tool and seek
medical attention.
WARNING: The engine exhaust from this
product contains chemicals known to
the State of California to cause cancer, birth
defects or other reproductive harm. Operate
your blower outdoors only in a well ventilated
area.
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. 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.
• 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 and dungarees
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. Wear protective goggles or
face screens. Use protections against
noises: for example noise reduction ear
guards 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

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.
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.
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 if the mixture is
to be stored for 12 months.
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.
FILLING THE TANK
Stir the mixture well before refuelling.
If you are using a petrol can to prepare the
mixture, make sure the container is clean
and mix for at least a minute to ensure the
oil is properly dissolved in the petrol. The oil
percentages are shown in the tables below.
WARNING: Follow safety instruction for
fuel handling. Always shut off engine
before fuelling. Never add fuel to a machine
with a running or hot engine. Move at least 3
m from refuelling site before starting engine.
DO NOT SMOKE!
1. Clean surface around fuel cap to prevent
contamination.
2. Loosen fuel cap slowly.
3. Carefully pour fuel mixture into the tank.
Avoid spillage.
4. Prior to replacing the fuel cap, clean and
inspect the gasket.
5. Immediately replace fuel cap and hand
tighten. Wipe up any fuel spillage.
NOTE: It is normal for smoke to be emitted
from a new engine during and after first use.
WARNING: Check for fuel leaks, if any
are found, correct before use. Contact a
Servicing Dealer if necessary.

WARNING! – Always wear protective
gloves during maintenance operations. Do not
carry out maintenance with the engine hot.
Never carry out maintenance operations with
the engine running.
- Non-correct maintenance and removal of
safety devices could cause serious injuries.
- Do not use fuel mixture for cleaning
operations.
- Do not attempt to carry out operations
or repairs that are not part of the normal
maintenance. See the authorised dealer.
AIR FILTER
The eciency of the air intake lter on any
engine is of critical importance so it must be
checked and cleaned regularly. To clean the air
lter, refer to Fig.17 and proceed as follows:
· Unscrew the two knobs to remove the cover
in order to gain access to the lter (as shown
in Fig.17).
· Remove the lter and clean it by knocking it
against a hard surface; then use compressed
air and blow from the side of the metal mesh
and between the pleats, proceeding in a
lengthwise direction.
· Ret the lter and close the cover, tightening
the two knobs.
CAUTION – Using the blower without the
air lter or with a very dirty air lter can damage
the engine and will invalidate the warranty.
Change the lter when it can no longer be
cleaned eciently.
FUEL FILTER (Fig. 18)
We recommend changing the fuel lter in the
fuel tank at least once a year. This operation
must be carried out by an Authorized Service
Centre:
· Empty the fuel tank.
· Extract the lter and disconnect it from the
fuel hose.
· Fit a new lter in the fuel hose.
· Re-insert the lter in the fuel tank.
CAUTION – Failure to replace the fuel lter
when it is dirty will result in impaired operation
of the engine.
ENGINE
Clean cylinder ns with a brush or compressed
air periodically. Dangerous overheating of engine
may occur due to impurities on the cylinder.
SPARK PLUG
Clean spark plug and check electrode distance
periodically (Fig. 16). Use Champion RCJ6Y or of
other brand with the same thermal grade.
FAN CASING
Following prolonged use of the blower a large
amount of dust may be deposited on the fan casing
(behind the cushion). This obstructs the air ow
(reduced volume) and can result in damage to
the fan and/or overheating of the engine. For this
reason, be sure to clean the fan casing regularly.
Clean the slots in the fan casing: they play an
important role in relation to engine cooling.
CARBURETOR
The carburettor is factory adjusted to standard
settings that comply with emissions regulations.
WARNING:
- Do not change the carburettor settings
by tightening or loosening the regulator
screws; this operation must be performed
by qualied personnel at an Authorized
Service Centre.
- Incorrect adjustment of the carburettor
can cause serious damage to the engine.
- Furthermore, do not tamper with or
remove the red protective caps on the
carburettor regulator screws.
In the case of problems (engine dies when
idling, irregular engine speed or failure to reach
maximum power) seek the assistance of an
Authorized Service Centre.
WARNING: Weather conditions and
altitude may aect carburation.

MUFFLER
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 muffler is damaged, it
must be replaced. If the muffler frequently
becomes blocked, this could be an indication
that the efficiency of the catalytic converter is
limited.
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.
EXTRA MAINTANANCE ADVISABLE
It is advisable to inspect the machine by a
specialized technician at an authorized service
network at the end of season, if used intensively,
and every two years if with normal use.
WARNING! – Any maintenance operations
not specifically dealt with in this manual
must be carried out by an authorised service
centre. To ensure that your blower continues
to function correctly, use only ORIGINAL
REPLACEMENT PARTS.
Any unauthorized changes and/or
use of non-original replacement parts
may result in serious injury or death to the
operator or third parties.
TRANSPORTION
Only transport the blower with the engine
switched off.
WARNING - When transporting the
machine on a vehicle, ensure that it is
firmly and securely fastened using straps or
belts. The machine must be transported in the
horizontal position, also ensuring compliance
with applicable transport regulations for such
machines.

8. STORAGE
WARNING: Stop engine and allow to cool,
and secure the unit before storing or
transporting in a vehicle. Store unit and fuel in
an area where fuel vapors cannot reach sparks
or open flames from water heaters, electric
motors or switches, furnaces, etc. Store unit
with all guards in place. Position so that any
sharp object cannot accidentally cause injury
to passersby. Store the unit out of reach of
children and other unauthorized persons.
1. Drain and clean the fuel tank in a well
ventilated area.
2. Drain all fuel from tank into a container
approved for gasoline. Run engine until it
stops. This will remove all fuel-oil mix which
could become stale and leave varnish and
gum in the fuel system.
3. Cleaan all foreign material from the saw. Keep
away from corrosive agents such as garden
chemicals and de-icing salts.
4. Abide by all Federal and local regulations for
the safe storage and handling of gasoline.
Excess fuel should be used in other 2-cycle
engine powered equipment.
CAUTION: It is important to prevent gum
deposits from forming in essential fuel
system parts such as the carburetor, fuel filter,
fuel hose, or fuel tank during storage. Alcohol
blended fuels (called gasohol or E10 or using
ethanol, methanol) can attract moisture
which leads to fuel mixture separation and
formation of acids during storage. Acidic gas
can damage the engine.
ENVIRONMENTAL PROTECTION
Environmental protection should be a priority of
considerable importance when using the
machine, for the benefit of both social cohesion
and the environment in which we live.
- Try not to cause any disturbance to the
surrounding area.
- Scrupulously comply with local regulations
and provisions for the disposal of oils, petrol,
batteries, filters, deteriorated parts or any
elements which have a strong impact on the
environment. This waste must not be disposed
of as normal waste, it must be separated and
taken to specified waste disposal centres
where the material will be recycled.
Demolition and disposal
When the machine reaches the end of its service
life, do not dispose of it into the environment;
instead take it to a waste disposal centre.
Most materials used in the manufacture of the
machine are recyclable; all metals (steel,
aluminium, brass) can be delivered to a normal
recycling station. For information contact your
local waste recycling service. Waste disposal must
be carried out with respect for the environment,
avoiding soil, air and water pollution.
In all cases, applicable local legislation must
be complied with.
