4.3 PRELIMINARY CHECKS
When you receive the machine, check that it is complete and no parts are
missing.
If there are any damaged parts, inform your local reseller or UNIGREEN
directly in good time.
When the machine is delivered, make sure you ask:
a) that the machine is delivered with all of its parts fitted and that the fitting
meets the requisites in table N° 10 (page 19). (This procedure is necessary
because for reasons of space during transportation the machine is often
delivered partially dismantled).
b) that it is tested in your presence in particular checking:
= that the suction filter and the inside of the tank are clean and free of work
residues.
= that the connections are made correctly following the basic layout (FIG.
N° 9, page 16).
= that the hose clips and all the unions and connections are tightened
properly.
= that all of the protective covers are fitted solidly to the machine, in
particular the protective cover of the power-takeoff of the pump.
4.4 APPLICATIONS
The UMP and MASTER machines are made to be mounted on the floors of vans
or similar vehicles. They can also be mounted on automobile type trolleys or
pickup vehicles with sufficient capacity. Always made sure before mounting that
the capacity of the trolley or the vehicle is sufficient. A tow-hook wheel kit NOT
approved for circulation on the road and suitable for small movements within
private areas is supplied on request.
4.5 MOTORS
4.5.1 ELECTRIC MOTORS
The electric motors of the motor-pumps correspond to the regulations in force
envisaged by the low-tension regulation and are guaranteed by the specific plate
of the constructor. The 20 Volt single-phase version is usually supplied with plug
and switch while the 380 Volt three-phase version is usually supplied with a
terminal board and the plug must be installed by an authorised and competent
installer. The plant to which the motor-pump is applied must correspond to the
regulations in force and be served by an automatic differential lifesaver switch.
Never, for whatever reason, direct the spray of the nozzle towards the motor.
Consult the specific use manual attached.
4.5.2 INTERNAL COMBUSTION ENGINES (TWO STROKE-PETROL-
DIESEL)
Use the motor keeping scrupulously to the use and maintenance booklet and in
case of need apply to the producer's assistance network.
Nevertheless, we list summarily a number of instructions to observe:
Petrol mixture motors (two stroke): respect the percentage of oil present in the
petrol and avoid the motor losing revs if the liquid contained in the cistern
unexpectedly finishes.
Petrol and diesel motors with electric starters: check the level of efficiency of
the battery and carry out normal maintenance.
Before starting check that the command lever of the pressure adjustor (lever A
page 10) is in the discharge position; starting is difficult in the pressure position
and might not take place.
To start an internal combustion engine proceed as follows:
= Open the fuel supply, putting valve A onto the ON position
= Put air lever B onto the closed position
= Select ON on the main switch of the motor (C)
= Pull start handle D or press the START switch (motors with electric starter)
= Gradually re-open the air (lever B) and adjust the speed.
ATTENTION: normally the parts that heat up (silencer, heads, etc) are protected.
However pay maximum attention to avoiding contact.
