Disassembly must be effected in the following manner:

1. disconnect the tubing attached to the pump.

2. remove the fixing screws and remove the tank, paying PARTICULAR ATTENTION to models containing a

grease pressure loading spring (it could be under pressure– in this case empty the remaining lubricant

first).

3. remove the pump and any filters.

4. unscrew the pneumatic cylinder of the pump paying PARTICULAR ATTENTION to the loading of the

spring; the component parts of the pump unit can then be disassembled.

In this way all component parts of the pump unit can be removed allowing the disassembly and cleaning of the

release and suction valves.

All pieces should be washed in petrol and lubricated prior to reassembly.

The following should be checked periodically:

VERIFY

The state of lubrication

The oil level

The cleanliness of the suction filter

The cleanliness of the loading/return filter

That the tank is clean and the bottom free from

deposits

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 (DPR 547/55) to avoid

injury to persons or damage to machine parts.

Repairs

The following diagnostic table indicates the main anomalies which may be encountered, the probable causes and

possible solutions.
