3.3 ENGINE PREPARATION (SEE ALSO
CHECKING SECTION)
Repairs required due to incorrect use by the
customer are not covered by the warranty.
WARNING: Remember that the engine does
not contain any oil initially and it must be filled
to the max. level by the user. Do not start the
engine without oil as this might cause irreversible
damage.
Only use SP95 lead-free petrol; the fuel must be
fresh; any fuel stored in a drum for more than 20 days
should not be used.
Use good quality 4-stroke engine oil with
suitable viscosity (such as SAE 10W20). If petrol
runs over the motor-driven pump, wipe it
thoroughly with a clean cloth before starting the
engine.
3.4 WATER INLET
Fit the pump with a suction pipe (not provided),
by fastening it to the threaded suction connector
B.3.
To ensure good flow, and above all correct
operation of the pump, the pipe transporting the
water must be taught, rigid, resisting low pressure,
with a minimum inner diameter of 30mm and no
longer than 7m, located close to the water
source. (The suction height should not exceed
5m).
The suction pipe must be equipped with a strainer
to avoid intake of debris and other particles that
might damage the pump and a check valve that
can keep the pipe full of water.
WARNING:
Never
a
strainer on the end of the suction pipe.
Foreign bodies are thereby filtered and will
not
cause
obstruction or damage to the
hydraulic unit.
WARNING:
The
and
connections must be perfectly intact to
prevent air from entering and suction losses.
The suction capacity of the motor-driven pump
is
reduced
or
connection between the connector and the
pipe is not hermetic. For all threading, use
PTFE tape to ensure sealing.
3.5 WATER OUTLET
The discharge pipe will be fastened to the
motor-driven pump by the B.2 threaded connector.
Respect the envisaged diameter to prevent load
losses,
and
maintain
characteristics for the motor-driven pump.
REMINDER: use of reduction fittings, 15 or 19 mm
garden-type or sprinkler-type quick connectors
is forbidden as they are completely inappropriate
for the flow transported by the pump. Restricting
the pump flow could damage it.
WARNING: Make sure that the fastening
clamp is properly tightened to prevent the
pipe from moving under the water pressure.

3.6.1 Engine switch B.17
The engine switch allows the engine to be turned
on or not. The engine switch should be in the ON
position when the engine is started up. By turning
the switch to OFF, the engine is stopped.
3.6.2 Choke lever B.6
This lever opens or closes the carburettor choke
valve. The lever must be in the CLOSE position for a
cold engine start-up. After start-up, leave the lever in
the OPEN position.
3.6.3 Starter handle B.12
Pulling on the handle activates the recoil starter to
start the engine.
WARNING: Do not allow the starter handle to
snap back, but guide it gently back through its
return movement.
3.6.4 Throttle - Accelerator B.11
Adjust the position of the throttle to obtain the
required speed. To find the right engine speed,
please refer to the machine specifications.
3.7 OPERATIONS TO BE PERFORMED BEFORE USE
3.7.1 Environment check
Look around and under the engine to check for
petrol leaks or drips. Check for damage or bumps
on the machine. Check that all plugs and protection
devices are in place and all screws and nuts have
been tightened.
3.7.2 Oil check - SEE FIG.E
E.1 and B.15 (FIG.B) - Oil dipstick
E.2 and B.4 (FIG.B) - Drain plug
E.3 - Upper oil level
E.4 - Lower oil level
WARNING: the oil level is to be checked when the
pump is horizontal - this check is compulsory -
this model does not have an oil level safety
device.
1- Unscrew the dipstick E.1 and clean it with a soft
cloth.
2 - Replace the dipstick and check the level by
the
withdrawing it again.
3 - If the oil level is too low, top up the oil.
4 - Having completed this operation, replace the
dipstick correctly.
Always check the oil level before start-up. Housing
capacity at max. level = around 350 ml.
3.7.3 Fuel check (unleaded 95 petrol) SEE FIG.F
First, stop the engine.
Open the petrol cap F.1 and B.9 (FIG.B) and check
the level according to the diagram. If necessary,
adjust the level and replace the petrol cap carefully.
Do not fill above the level of the neck of the fuel filter
F.2. Typical total fuel volume: around 1.8 l.
