BASICS
• The equipment comes with a suction tube and with an
impulsion tube, the first having a larger diameter than
the second. Assembling is designed in such a manner
that it is impossible to assemble the tubes mistakenly
or to insert them mistakenly into the sockets.
• Depending on the use, you may mount the one-
segment the two-segment tube by means of the pin
connection and the pair of screws thereof.
• As a safety measure, the machine has a sensor that
prevents operation when the cover (14) of the suction
device is open or the conduct is not installed well.
• Always position the tubes with the motor turned-off.
ASSEMBLING THE IMPULSION TUBE
• Insert the tube directly into the socket 14 respecting the
upper groove and tighten the fastening wing nut. If you
wish, you may mount the deflector terminal to increase
the sweeping pressure.
ASSEMBLING THE SUCTION TUBE
• Open the lid of the suction socket 13 by smoothly
levering with a flat screwdriver at the right of the retainer
clip 16.
• Insert the tube in such a manner that the radial
projection presses on the safety sensor that is next to
the hinge of the lid 14. Once introduced turn leftwards
to fasten the tube.
• Assemble the suction bag to the impulsion socket by
fitting the upper pin and tightening the fastening wing
nut.
Before carrying out any work at the blower,
always stop the motor and separate the spark
plug connectors.
Always wear protective gloves.
Start the blower only after having assembled it
completely.
WARNING:
Do not try to collect large wood shavings, metal,
glass, stones, liquids, lighted cigarettes, pyrotechnic
products or similar ones.
Always assemble the tube of the suction device in the
correct manner before starting the machine. Operation
without the tube of the suction device is dangerous; the
propeller may trap your fingers or clothing and cause
serious damages.
Do not try to disassemble the tube of the suction device
when the machine is operating.

4. Operating instructions

WARNINGS:
• Do not allow the motor to be started at a place where
refueling has been made.
• Exhaust gas is toxic. Do not start the motor at a location
without adequate ventilation such as interiors, tunnels,
etc.
• Once started, if felt rare in sound, smell, vibration, etc.
stop the motor immediately and check it.
• Check that the motor will stop when the stop switch is
in position "O".
• When the choke lever is raised higher than he position
"CLOSE" the motor may become damaged.
• When the motor detonates and stops, put this lever
again into position "OPEN" and pull the starter knob
several times to start the motor again.
• If the operator keeps on pulling the starter when the
lever of the throttle is in position "CLOSE", it is possible
that it results difficult to start the motor due to fuel
flooding.
• In case of fuel choking, remove the sparkplug and pull
the grip several times to discharge any excess of fuel.
Dry the sparkplug's electrode.
4.1 General instructions for use
Starting mode
1) When the motor is cold or after refueling:
- Place the machine on a flat surface.
- Put the stop switch into position "I".
- Continue pushing the priming pump until fuel enters
into it.
• Generally, fuel enters into the carburetor after having
pushed 6 times.
• When the priming pump is pushed excessively, an
excess of gasoline returns to the fuel tank.
- Turn the choke lever (starter) to the left to the closed
position.
- Hold the main handle with your left hand to avoid
that the motor moves.
- Smoothly pull the starter grip until noticing a resis-
tance (compression point). Then return the starter
grip and pull strongly. The machine will start.
• Never pull the cable up to the limit.
• When pulling the starter grip, do not release it
immediately. Hold the starter grip until it has returned
to its original position.
• Open the choke lever progressively at the same time
as checking the operation of the motor. Make sure that
you open the choke lever fully at the end.
