• In cold weather or when the motor is cold, never open
the choke lever suddenly. If done so, the motor may
stop.
- Allow the motor to warm up for 2 or 3 minutes.
- Warming up will be completed when a quick acce-
leration of the motor from a few rpm to full power
takes place.
2) When the motor is warm:
- Place the machine on a flat floor.
- Make sure that the choke lever is open.
- Hold the main handle with your left hand to avoid
the motor to move.
- Slowly draw out the starter grip until noticing a cer-
tain resistance. Then return the starter grip once
and pull strongly.
- In case that starting the motor should be difficult,
proceed to start it with the butterfly open at 1/3.
3) Stopping mode:
Release the triggering lever to reduce the motor speed
and adjust the stop button to position "O".
OPERATING PROCESS
Operation of the blower
• Hold the blower correctly during operation.
• Direct the tip of the nozzle towards an object to be
blown and press the speed trigger.
• Press the speed lever completely.
• As the lower portion of the fuel tank is the support
handle, you may handle with your two hands. In this
case, you must hold the support handle with your right
hand.
Suction operation
Proceed in a similar manner as when blowing, taking into
account the following warnings:
WARNING:
• Do not allow oil, fuel, gasoline, lighted cigarettes
etc. to be suctioned.
- You may cause fire.
• Do not suction large pieces of wood, metal, glass,
stones or other strange objects.
- You may cause breakdowns.
• A dust bag that is too full may spill over and spill
towards the motor side. Empty the bag before it
has been filled completely.
- You may cause fire.
• Hang the belt of the dust bag over your shoulder
and adjust the length of the belt to facilitate
operation.
• Make sure that the dust bag is not twisted and
proceed to the dust collecting operation by pulling
the triggering lever.

2. Check the high-voltage sparkplug.
The distance between the two electrodes is 0.7 - 0.8
mm.
In the case that the distance should be too large or
too small, adjust it so as to make it have the adequate
distance.
In the case that the high-voltage sparkplug should bear
accumulated carbon, it must be cleaned completely or
replaced.
3. Do not over tighten the sparkplug when mounting it.
Once it has reached the limit, tighten 1/4 turn more.

5.2 Air filter

Open the cover 13 by pressing with your finger at the right
of the clip 16.
Blow the filter with compressed air and thereafter wash it
with detergent and water. Once dry, mount it and close the
cover checking the retention of the clip 16.
Before using the equipment always check the filter

5.3 Fuel

• Stop the motor.
• Loosen the tank lid somewhat to release pressure from
the tank.
• Remove the tank lid and refuel at the same time that
you allow air exiting by inclining the fuel tank such that
the refueling opening is orientated upwards. (You must
NOT ever fill the tank up to spilling over.)
• After refueling, tighten the tank lid firmly.
• Replace the tank lid if there is any defect or damage.
• The tank lid becomes damaged with the path of time.
Replace it every two or three years.
• Use 95 octane gasoline mixed with 30 : 1 2T motor oil.
FUEL STORAGE PERIOD
Fuel must be used within a period of 4 weeks even when
stored in a special recipient in a shadowed and well-
ventilated area.
When no special recipient is used or it is not covered, fuel
may deteriorate within one day. Storage of the machine
and the refueling tank:
• Keep the machine and the tank at a fresh location free
of direct sunlight.
• Never leave fuel in an automobile.
When refueling the unit, make sure to observe
the following instructions to prevent ignition
or fire:
- Fuel supply must be made at a location where
there is no fire. Do never bring fire (smoking,
etc.) near the location where fuel supply is ta-
king place.
- Stop the motor and let it cool down before refue-
ling.
- Open the fuel lid slowly. It is possible that fuel
spills over if there is inner pressure.
- Be careful to not spill the fuel. Any spilled fuel
must be cleaned.
- Carry out refueling at a location with adequate
ventilation.
