ANOMALY

Irregular flow rate Screw C, which secures

the pump element D and

return spring E, is loose.

9. MAINTENANCE PROCEDURE

Locate the machine in conditions which facilitate easy access.

Utilise individual protection to avoid contact with mineral oil.

Periodic inspections

Periodically it is necessary to check:

VERIFICATION

The state of lubrication

The oil/grease level

Cleanliness of the filling and intake filter (where fitted)

The machine does not require any special tools to carry out checks or maintenance tasks, However, it is

recommended that only tools suitable for the tasks and in good condition should be utilised to avoid injury to persons

or damage to machine parts.

9.1 Assembly/Disassembly

No pump assembly operations are envisaged.

For wall mounting ensure adequate space is available (as shown in the installation diagram) to avoid abnormal

postures and possible impacts; four fixing holes are provided for wall mounting and three for base fitting.

Subsequently it will be necessary, as previously described, to connect the pump to the machine hydraulically and then

to connect the control panel.

During the disassembly phase ensure the tank is empty.

Disconnect the electrical and hydraulic parts.

Where the machine is to be scrapped, do not dispose of potentially polluting parts in the environment, following local

regulations for their correct disposal.

At the time of the machine being scrapped it is necessary to remove and destroy the identification plate and all other

relative documents.

9.2 Regulation

Flow rate (for versions with adjustable flow rates)

It is possible to regulate the flow rate by rotating the regulating screw (8 mm hexagonal key) clockwise to decrease

CAUSE

Remove

assembly from the pump body

and completely disassemble it.

To reassemble the pump element

assembly see the sequence in the

diagram.

Check all the parts and reassemble

after having washed them all in

petrol.

Warning: put some Loctite type

sealant on screw C, which is

inserted into pump element D.

Hold the pump element between

wooden vice clamps to prevent

damage to the lapped surface.
