2.7 ELECTRIC MOTORS (BATTERY, 230V AND 400V)
2.7.1 SAFE USE OF THE MOTOR, BATTERY AND BATTERY CHARGER
•The battery charger may only be connected to a mains power supply from a minimum of 100V
up to a maximum of 240V AC 50/60Hz, using exclusively an adequate power cable equipped with
a EURO plug, and, if necessary, connected using an appropriate power adapter (sold separately).
-Make sure that the connection to the power supply is made with the correct voltage level
present.
-Always use the correct adapter for the outlet.
-In countries for which a proper outlet adapter is not included in the consignment, and
countries in which the mains voltage values do not correspond to the specifications
provided for the battery charger, the battery charger cannot be connected to the mains
power supply. In these cases, the user is advised to contact a local assistance centre in
order to find out how the battery charger can be properly connected to the mains power
supply network.
•Always grip the plug directly when inserting or removing it from the power outlet; never pull on
the cable.
•The battery charger may only be used to charge the batteries supplied by M.M. srl for this
pressure sprayer with a proper connection to the battery.
•In order to avoid short-circuiting, never connect the battery's terminals (+ / -) to one another
using a conductive object.
•Keep the battery charger, the battery, and all the electronic parts of the unit away from the
water spray, and be careful not to strike the wheelbarrow sprayer itself with the jet of water, as
this could cause an electrical short circuit. The components must only be cleaned using a dry or
slightly damp cloth. Prior to cleaning, disconnect the unit's plug from the power outlet, and
disconnect the charging cable from the charging device.

4.1 WATER CIRCUIT SCHEME
4.2 DESCRIPTION OF THE MACHINE
This machine is compliant with the essential Health and Safety requirements of European Directive
2006/42/EC, as amended. This machine is a wheelbarrow sprayer-mounted sprayer (see Fig. 2 on
page 17) equipped with a manual lance (7) or an optional boom (45 or 51) designed to break down
the liquid into small droplets, which are produced thanks to the water pressure generated by the
pump (4). It is made up of an entirely powder coated frame (8) with one or more pneumatic tyres
(10), a polyethylene tank (1), and a pump (4) with the relative water circuits. The tank is equipped
with a graduated scale level indicator (25). The tank can be emptied via a lid (19) on the bottom of
the tank itself. The high pressure volumetric pump is powered directly by the electric motor or
combustion engine. The pump draws the product from the tank and delivers it to the jet under
pressure (see Fig. 1 on page 15). The adjustment system operates under constant pressure. The
operating pressure is controlled via a pressure gauge (48) mounted, when supplied, near the
adjustment unit (or control unit –see sec. 4.3.3) at the front of the machine, or upon the same
unit's graduated scale (with the exception of the 12v ECO models, which operate at a fixed pressure
value).

WHEELBARROW SPRAYERS
4.3.1 TANK
The polyethylene tank (1 –Fig. 2) has a smooth inner surface without any sharp angles, which
facilitates the liquid mixing and cleaning operations.
4.3.2 SUCTION FILTER
The suction filter serves to prevent the pump from suctioning any impurities or residues.
The filter can be two types:
•inside the tank
•outside the tank (2 –Fig. 2)
In both cases the filter's mesh is ISO Blu 50 MESH
4.3.3 PRESSURE REGULATOR
Before initiating the work activities, it is recommended to adjust the pressure using clean water, and
to check for any leaks around the couplings and fittings.
To adjust the operating pressure, do the following:
1) Start the electric motor or combustion engine by following
the instructions in the relative handbook.
2) Open the lance to prime the pump.
With control unit A 9620122
3) The pressure shown on the pressure gauge (2) can be
increased or decreased by turning the red knob (1)
clockwise or anti-clockwise, respectively.
4) With the lance closed, the valve keeps the pump
pressurized and, without compromising its functionality,
discharges the fluid into the tank.
5) With the red knob (1) completely tightened, the pump will
shut off once the lance is closed.
With the VRI control unit
3) Screw in the black knob (1) to increase the pressure to the
value shown on the graduated scale (2), and unscrew the
knob (1) to decrease the pressure.
4) Turning the red knob (3) to the A position will cause the
water outlet to the lance to close, with the water being
discharged into the tank. With the red knob (3) turned to
the C position, the outlet is opened and the circuit is
pressurized.
5) With the lance closed, the valve keeps the pump
pressurized and, without compromising its functionality,
discharges the fluid into the tank.
With the GR 30 control unit
3) The pressure can be increased or decreased by turning the
red knob (1) clockwise or anti-clockwise, respectively, until
the desired operating pressure is shown on the pressure
gauge (3).
4) Turn the lever (2) clockwise to discharge the liquid into the
tank, and anti-clockwise to open the outlet and pressurize
the circuit.
5) With the lance closed, the valve keeps the pump
pressurized and, without compromising its functionality,
discharges the fluid into the tank.

3) The pressure can be adjusted by inserting the connecting
rod (1) into the 4 notches (2) until the desired pressure is
shown on the pressure gauge (3). Fine adjustments can be
made using the adjustment dial (4).
4) With the lance closed, the valve keeps the pump
pressurized and, without compromising its functionality,
discharges the fluid into the tank.
5) Once the work operations have been completed, remove
the connecting rod (1) from the notches (2) to release the
spring.
With the RM 40 control unit
3) Push down and turn the red knob (1) clockwise to
quickly drain the liquid into the tank. Turn the red knob (1)
anti-clockwise to open the outlets to the utilities.
4) Pull the red knob (1) →upward to adjust the operating
pressure: turn it clockwise or anti-clockwise to increase or
decrease the pressure, respectively.
5) With the lance closed, the valve keeps the pump
pressurized and, without compromising its functionality,
discharges the fluid into the tank.
After completing the work activities, rinse out the inside of the unit, the lance hose's
regulator, and the pump with clean water in order to eliminate any aggressive
product residues.
