Flame Strictly

Forbidden

To prevent an accident or fire, strictly observe the following instructions when handling
fuel or operating the blower.(Fig.4)

_WARNING
Fuel is flammable. Operate the blower only where there is no flame.
If you are storing or mixing fuel, do it where there is no flame.
While operating the blower, keep away from flames.
Do not smoke while handling fuel or operating the blower.
Do not add fuel while the engine is hot. Wait until the engine is cool.
Do not add fuel to the fuel tank while the blower engine is operating.

Before Operation

Fig .4

To prevent injuries and accidents, check the following items before operating the blower.

_WARNING
• If you discover fuel leakage, do not start the blower.
• Check that the anti-vibration rubber has no cracks or damage.
• Make sure the tank cap is tightened securely. If it is loose or not installed level, fuel
could leak and be extremely dangerous.
• Do not modify the blower. In particular, never perform modifications to deliberately
increase the engine speed.
• Always check that the muffler is not damaged or corroded. Aworn or damaged muffler
may produce sparks or flame and is dangerous.(Fig.5)

Fig.5

• To reduce noise, do not operate two or more blowers at the same time.
• Before starting the blower, check that there is no fuel leakage around the fuel hose, fuel
tank and carburetor.
• When you start the blower engine, push the blower toward the ground with one hand
on top of the body while you pull the starter cord.(Fig.6)
• Hold the start cord handle firmly. Do not pull it too hard and do not release it suddenly.
• When performing repairs or replacing parts, use genuine factory parts.
• Before operating the blower, check each part (particularly the muffler, intake port and
air filter) for wear, looseness and damage.
• Check that the blower condition is normal. If the blower is not normal, do not operate it.
• Check that there is no oil or fuel on the machine exterior. If you get oil or fuel on the
machine exterior, wipe it off promptly and wait until the machine is fully dry before
operating the blower.
• Operate a separate container for mixing fuel. Do not operate the blower fuel tank to mix
fuel.

Fig.6

• Before you start the engine, check there are no foreign objects within the housing.

Fig.7

During Operation
Take care with the following items during blower operation to prevent personal injuries,
accidents or machine breakdown.

/_WARNING
• The blower generates powerful suction, so do not operate the blower when wearing
loose clothes and unrestrained long hair.
• Keep your hand away from the blower intake port during operation.
The fan operates at high speed and is dangerous.(Fig7)
• Do not insert anything into the blower intake port during operation.
• Do not perform maintenance, disassembly or reassembly during blower operation.
• There is danger of electric shock and burns during blower operation and immediately
afterward, so do not touch the spark plug, muffler or engine cover.(Fig.8)(Fig.9)

English

Fig.8

Fig.9

• Operate the blower correctly. Do not hold the body in your hands when operating the
blower.
• The fan operates constantly during blower operation, so take care to prevent it.
• The blower operates the fan at high speed to generate wind. Do not apply shocks or
external force to the machine during operation.
• Do not insert anything into the pipe. Always take care to prevent blowing fragments at
persons, animals, plants, trees, vehicles and walls.
• Take care with the air pressure. Flying stones, dust and branches can injure persons
and animals, and break glass.(Fig.1O)
• Do not point the pipe outlet port toward people or animals.
• Do not operate the blower to spread substances that may be injurious to humans, such
as chemicals, fertilizers and poisons.
• If you detect abnormal vibration or noise during operation, promptly stop the blower and
check whether something has broken. If a breakdown has occurred, do not operate the
blower until the problem is fixed.
• Before you start the blower, make sure that all attachments such as the pipe are
installed securely. If installation is incomplete, performance may be reduced, the engine
speed may drop, and an accident or breakdown may occur.
• Check that the housing intake port and pipe output port are not blocked by leaves or
waste, etc.

Fig.10

If the housing intake port or pipe output port is blocked, blower performance is reduced
and damage may result from engine overheating.
• If the housing intake port or pipe output port is blocked, stop the engine and remove the
leaves or waste, etc.(Fig. 11)

Fig.11

• Do not remove the fuel cap during or immediately after blower operation.
• Always stop the engine when halting work or performing maintenance. Before you
perform maintenance, also remove the spark plug.
• If the engine does not stop when you operate the stop switch, turn the choke to a fully
closed position in order to stop the engine.

After Operation
When you have finished operating the blower, store the blower in accordance with the following instructions to prevent the
danger of fire or an accident.

WARNING

• When you release the fuel cap, turn the fuel cap slowly to gradually release the internal pressure generated in the

fuel tank.

• Drain the fuel before storing or transporting the blower. Do not store the blower with fuel still remaining in the tank, hose
and carburetor.
•
•
•
•

Store the blower away from humidity and flames, and out of reach of children.
Store the fuel in a receptacle certified suitable for flammable fluids.

MAINTENANCE
Carburettor

Basic setting

Your product has been designed and manuihctured
to specifications
that reduce harmful emissions.

• The carbureetor is set to its basic setting when test run at the
l]_ctoU. The basic setting is richer than the optimal setting
and should be kept during the machine's first working
hours. Thereafter the earburertor should be finely adjusted.
Fine adjustment should be carried out by a skilled
technician.

After your unit has been run 8-10 tanks of fuel the engine
has broken in. 'lib ensure that your unit is at peak
performance
and producing
the least amount of harmful
emissions after break in, have your authorized servicing
dealer, who has a revolution counter at his disposal,
to adjust
your carburettor for optimum operating conditions.

Fine adjustment
• When the machine has been "run-in" the carburettor should
//_

be finely adjusted. The fine adjustment should be carried
out by qualified person. First adjust the L-jet, then the
idling screw "l' and then the H-jet.

The machine must only be started as a
WARNINGt
complete unit. If the machine is started
without all the covers fitted there is a risk
of personal

injury.

Conditions
• Before any adjustmems are made the ah:filter should be clean
and the airfilter cover fitted. Adjusting the earburettor while
a dirty airfilter is in use will result in a leaner mixture when
the filter is finally cleaned. This can give rise to serious
engine daurage.

Operation
• The carburettor governs
the engine's speed via the
throttle. Air/fuel is mixed
in the carburettor. The
air/{uel mixture is
adjustable. To take
advantage o_'the engine's
optimal output the
adjustment must be
correct.
• The setting of the
e_trburertor means that
the engine is adapted to
local conditions, for
example, the climate,
altitude, petrol and the
type of 2-st_:oke oil.
