Wear sound barriers(ear plugs or ear mufflers) to protect
your hearing.
Wear heavy-duty, nonslip gloves, preferably made of
chrome leather.
Never touch a hot cylinder or muffler ,or burn will result.
Always stop the engine before refueling.
Gasoline is an extremely flammable fuel. Do not smoke or
flame near the fuel. Do not fuel a hot engine—fuel may
spill and cause a fire.

4
Remove the fuel filler cap on the unit carefully so as to allow any
pressure build-up in the tank to release slowly.
Fuel your blower in well-ventilated areas, outdoors only. Wipe off
any spilled fuel before starting and check for leakage.
Take care not to get fuel on your clothing. If this happens, change
immediately.
Unit vibrations can cause an improperly tightened fuel
cap to loosen or come off and spill quantities of fuel.
In order to reduce risk of fuel spillage and fire, tighten fuel cap.
On units with a screw cap: tighten the cap by hand with as
much force as possible. On units with hinged handle on the fuel cap:
Tighten as described in chapter“Fueling”
Check for fuel leakage while refueling and during operation. If
fuel leakage is found, do not start or run the engine until the leak is
fixed.
Store gasoline and oil in properly labelled, approved
safety-type cans.
Transporting the unit
Always stop the engine.
Transporting in a vehicle: Properly protect the unit to prevent
turnover, fuel spillage and damage. When the unit is not in use, put it
down so that it dose not endanger others.
Before starting
Check the following points
·Throttle trigger must move freely and spring back to idle
position when released.
·Stop switch must move easily to “off”.
·Tightness of spark plug cap—if the cap is loose, sparks may
occur and ignite the escaping fuel vapor.
Starting
·Start the engine at least 3m from the fueling spot, outdoors

5
only.
·To reduce the risk of breathing toxic fumes, never start or run
your unit in confined spaces.
·Place the unit on firm ground in an open area.
·Make sure you have good balance and secure footing.
·Hold the unit securely.
Your blower is a one-person unit. Do not allow other persons to be
near the running unit—even when starting.
For specific starting instructions, see chapter “Starting” in the owner’s
manual.
During operation
Warning
Your blower produces toxic exhaust fumes when the
engine is running. These gases (e.g. carbon monoxide) may be
colorless and odorless. To reduce the risk of serious or fatal injury
from breathing toxic fumes, never run the blower indoors of in poorly
ventilated locations.
Ensure proper ventilation when working in trenches, hollows
or otherconfined areas.
To reduce the risk of igniting the combustible fuel vapor
and causing a fire, never smoke while working with or
standing next to the blower.
Always hold your unit firmly—make sure you always have a firm
and secure footing.
Examine the work area: Do not direct the air blast towards bystanders
since the air flow can blow small objects at great speed.
Take care in slippery conditions
·On ice ,in wet or snow
·On slopes or uneven ground
Watch out for obstacles
Roots, ditches, holes or rubbish which could cause you to trip

6
or stumble.
Warning: when spraying
To reduce the risk of inhaling poisonous fumes from chemicals and
exhaust gases, do not operate the blower in confined spaces.
Walk forward only when the unit is running..
In an emergency, release the quick-action buckles, slip out of the
harness and throw off the machine.
After finishing work, drain and clean the container.
Vibrations
Prolonged use of the unit may result in vibration-induced circulation
problems in the hands.
No general recommendation can be given for the length of usage
because it depends on several factors.
The period of usage is prolonged by:
---Hand protection (wearing warm gloves)
---Break
The period of usage is shortened by:
---Any personal tendency to suffer from poor circulation
(symptoms: frequently cold fingers, itching)
---Low temperatures outside
---Gripping force (A tight grip hinders circulation)
Continual and regular users should monitor closely the condition of
their hands and fingers. If any of the above symptoms appear, seek
medical advice.
Maintenance and repairs
Do not attempt any maintenance or repair work not described in the
owner’s manual.
Have such work performed at your service shop only.
Never modify your power tool in any way as this could result in
serious injury.
Always stop the engine and disconnect the spark plug cap before doing
any maintenance or repair work or cleaning the

7
machine.(Exception: carburetor and idle adjustments.)
Always clean dust and dirt off the machine after finishing work.
Do not store or service your unit near any fire or flame
----Check fuel cap regularly for leak
----Use only the approved spark plug (see specifications) and make
sure it is in good condition
----Inspect ignition wires (insulation in good condition, secure
connect)
----To reduce the risk of fire due to ignition outside the cylinder, move
the stop switch to OFF before turning the engine over on the
starter with the spark plug cap removed or the spark plug
unscrewed.
----Check the condition of muffler periodically
----To avoid the risk of fire or hearing loss, do not operate your unit if

Fueling
Your engine requires a mixture of gasoline and engine oil. The quality
of these constituents and the mixed ratio has a decisive influence on
the function and service life of the engine.
Unsuitable fuel or lubricants or mixed ratio other than those
specified may result in serious damage to the engine.
Gasoline
Use only regular branded gasoline with a minimum octane rating or
90#. If the octane rating of the regular grade gasoline in your area
is lower, use fuel--leaded or unleaded.
For health and environmental reasons, you should give preference to
unleaded gasoline.
If your machine is equipped with a catalytic converter, you must use
unleaded gasoline.
A few leaded gasoline will greatly reduce the efficiency of the catalytic
converter.
Engine oil
Use only quality two-stroke engine oil.
Other quality two-stroke engine oils must conform to classification
TC.

10
Poor quality gasoline or engine oil may damage the engine, sealing
rings, hoses and the fuel tank.
Mixing fuel
Avoid direct skin contact with gasoline and avoid inhaling gasoline
vapor.
Use a container approved for storing fuel. Pour oil into the container
first, then add gasoline , and mix thoroughly.
Mix ratio
Two-stroke engine oils (classification TC): 40（gasoline）：1（oil）
Storing fuel
Fuel ages:
Only mix sufficient fuel for a few months work. Store in approved
safety-type fuel container in a dry and safe location.
·Thoroughly shake the mixture in the container before fueling your
machine. Pressure may build up in the container—open it carefully.
·Clean the fuel tank and container from time to time.
Dispose of cleaning fluid properly at authorized disposal location.
·Before refueling, clean the filler cap and the area around it to ensure
that no dirt falls into the tank.
·Position the unit so that the filler cap is facing up.
Take care not to spill fuel while fueling and do not overfill the tank.
After refueling, tighten down filler cap by hand as securely as
possible.
Change the fuel filter once every year
·Drain the fuel tank
·Use a hook to pull the fuel filter out of the tank
and take it off the hose.
·Push the new filter into the hose.
·Place the filter in the tank.

Operation instructions
During break-in
A new machine should not be running at high speed. This avoids
unnecessary high loads during the break-in period. As all moving parts
have to e fitted during the break-in period. The frictional resistances in
the engine are greater during this period. The engine develops its
maximum power after about 5 to 15 tank fillings.
During operation
After a long period of full-throttle operation, allow engine to run for a
while at idle speed so that the heat in the engine can be dissipated by
flow of cooling air. This protects engine-mounted components
(ignition, carburetor etc.) from thermal overload.
After finishing work
Storing for short period:
Wait for engine to cool down. To avoid condensation, fill the fuel tank
and keep the unit in a dry place until you need it again. Storing for a
long period: see chapter “Storing the machine”
Cleaning the air filter
Dirty air filters reduce engine power, increase fuel consumption and
make starting more difficult.
If there is noticeable loss of engine power
·Close the choke
·Pull A and remove the air filter cover
·Remove the filter from the cover and inspect it. If it is dirty or
damaged, clean the filter or fit a new one.
·Install the filter
·Fit the cover and tighten the screws

Carburetor
General information:
Your carburetor comes from the factory with a standard setting.
This setting provides an optimum fuel-air mixture under most
operating conditions.
The high speed screw alters the engine power output and the
maximum off-road engine speed.
If the setting is too lean, there is a risk of engine damage due to
insufficient lubrication and overheating.
Checking the spark plug
If engine is down on power, difficult to start or runs poorly at idle
speed, first check the spark plug.
·Remove the spark plug, see “starting/stopping the engine”
·Check electrode gap A (0.6-0.7mm) and adjust if necessary, see
“specifications”
Rectify the problems which have
caused fouling of spark plug
----Too much oil in fuel mixture
----Dirty air filter
----Unfavorable running conditions
Fit a new spark plug after about 100 operating hours, or sooner the
electrodes are badly eroded.
·
If the spark plug comes with a detachable adapter nut, screw it firmly.
·Press the cap firmly onto the spark plug
A

15
Engine running behavior
If engine running behavior is unsatisfactory even though the air filter
is clean and the carburetor properly adjusted, the cause may be in the
muffler.
Have the muffler checked for contamination by dealer.
Storing the machine
For periods of about 3 months or longer
·Clean the fuel tank
·Run the engine until carburetor is dry---This helps prevent carburetor
diaphragms sticking together.
·Thoroughly clean the machine—pay special attention to the cylinder
and air filter
·Store the machine in a dry, high or locked location out of the reach of
children and other unauthorized persons
·Do not expose the container to direct sunlight for unnecessarily long
period. UV rays can make the container material brittle, which could
result in leaks or breakage.
