be done on a flat and stable surface, with enough
space for moving the machine and its packaging,
always making use of suitable equipment.
With the air vent closed, push the straight nozzle pipe
over the discharge port and lock it in. The arrowhead
on the straight nozzle pipe should be on the same line
with the volute case (Fig. 6). Rotate the pipe clockwise
to lock. Then tighten the screw in place to secure
(Fig. 7). Push the blower nozzle pipe over the straight
nozzle pipe and locking pin. Rotate the pipe clockwise
to lock (Fig. 8). The side of the blower nozzle pipe that
says «THIS SIDE UP» must face upwards. Then tighten
the screw in place to secure.
Before starting work please:
1. Check that all the screws on the machine are
tightly fastened.
2. Check that the air filter is clean.
3. Check that vibration absorbers are fine.
4. Prepare accessories and make sure they are
correctly mounted.
5. Fill with fuel as indicated below.
FUELING AND LUBRICATION
WARNING: Never smoke whilst refueling and avoid in-
haling the petrol fumes.
The blower is equipped with 2-stroke engine. There-
fore, mixture of petrol (of 90 octane or higher) and
2-stroke oil must always be used. It is very important to
pay attention with the fuel mixture that you use, since
accurate mixture of oil and fuel must be obtained.
Small quantities of oil and fuel mixture with small
inaccuracies, can affect the ratio of mixture, which
may lead to engine overheat and serious damages in
the engine. It is recommended that you mix only the
amount needed for the job that you are about to do, in
order to keep only fresh mixture.
WARNING: Carefully open the tank top as pressure
could have formed inside.
Especially formulated 2-stroke oil for air cooled
2-stroke engines must be used. Do not use 2-stroke
oil intended for water cooled engines. Never use poor
quality of oil or 4-stroke engine oil.
For best results and performance, the mixing ratio of
gasoline to oil is 50:1.
Always use clean container for fuel before mixing the
fuel. Mix and shake the fuel mixture thoroughly, be-
fore filling the machine’s fuel tank. Do not use fuel
mixture stored for more than a month. The fuel tank
of the machine must be emptied before storage.
Always use a funnel to refuel the machine.
Do not overfill. Leave a minimum 5 mm of space be -
tween the top of the fuel-oil mixture and the inside
edge of the tank to allow for expansion.
WARNING: Always close the fuel tank cap firmly.
STARTING THE UNIT
Before starting the engine, place the machine on sta-
ble ground.
1. Fill the fuel tank with the correct amount of fuel
and oil mixture.
2. Turn On/Off switch to “ON” position (Fig. 2.7).
3. In case of cold start: Pull the choke to the fully
extended position so that the choke is closed
(Fig. 3.10).
4. Press and release the primer bulb 7-10 times
until it is full with fuel (Fig. 4.11).
5. Keeping the unit placed firmly on the ground
or a very sturdy work surface, grasp the starter
rope with one hand and push on the engine
cover with the other (Fig. 10). Make sure all
bystanders are a minimum of 15m away. Do not
attempt to start near pilot lights or any open
flame. Pull the starter rope slowly once until you
feel the engine engage.
6. Start the machine by pulling the starter rope
upwards briskly. The unit should start within 5
pulls.
WARNING: To avoid breaking the starter rope, do not
pull the whole length of it or let it slide along the edge
of the cable guide hole. Release the starter gradually,
to avoid letting it fly back uncontrollably.
NOTE: Once warm, the engine should start on the first
pull.
NOTE: Squeeze the throttle control slightly to warm
up the engine for 15 to 30 seconds. In cold weather,
move the throttle slowly until the engine warms up for
30 to 60 seconds.
7. Return the choke to fully open position once the
engine running speed stabilizes.
For maximum performance and reliability, allow the
engine to warm up before operating. Run the engine
for 2-3 minutes at idle speed.
WARNING: The machine must always be firmly gripped
with your right hand on the upper handgrip during
work (Fig. 11).
Engine speed should be adjusted to the type of
material to be removed:
• Use the engine at low speed for lightweight
material and small bushes on the lawn.
• Use the engine at average speed to move grass and
lightweight leaves on pavement or solid ground.
• Use the engine at high speed for heavier materials
like fresh snow or voluminous dirt.
WARNING: Always pay the utmost attention to pre-
vent removed material or dust from injuring people
or animals or damaging property. Always assess wind
direction and never work against the wind.
STOPPING THE UNIT
1. Release your hand from the throttle control.
Allow the engine to cool down by running in idle
for 2-3 minutes.
2. If your unit is equipped with a spring loaded On/
Off switch, press and hold the button on “O”
position until the engine stops. Otherwise, push
the switch to the “Off” position.
MAINTENANCE AND CLEANING
WARNING: Before cleaning or doing maintenance
work, disconnect the spark plug cap and read the rele-
vant instructions. Wear proper clothing and protective
gloves whenever your hands are at risk.
WARNING: Never do maintenance or cleaning with the
unit running. Always work on a cool unit.
Any adjustments or maintenance operations not de-
scribed in this manual must be carried out by your Deal-
