• BRAKE SYSTEM BLEED
Bleeding consists in eliminating the air inside the system. This operation must be performed each time hydraulic parts of the
system are disassembled.
Carry out the operations needed to bleed the brake system on both axles and just on the callipers that have the special screw
"A"
-
fully depress the brake pedal.
- loosen the bleeder screw (A).
- close the bleeder screw (A).
- pump the brake pedal repeatedly.
- repeat from the first point until the fluid exits the bleeder screw without air.
• CLEANING OF THE MACHINE AND ATTACHMENTS
WARNING! All the described operations have to be carried out with the engine off (it is advisable to remove
the ignition key from the instrument panel).
To clean correctly follow these instructions:
-
wear suitable personal protective equipment (gloves, masks, glasses, overalls, etc.)
- do not use flammable liquids and acids or products which could chemically attack the vehicle parts
- do not clean moving or overheated parts.
- the same products used for cleaning cars can be used to clean the inside of the cab. Pay particular attention to remove
the build-up of dust, grease or other from the machine's controls.
- to clean the outside of the vehicle and the engine, it is advisable to use a pressure washer, keeping in mind the following:
- make sure that all filler caps (of the radiator, of the oil tank for both the hydraulic system and the hydrostatic
transmission, of the fuel tank) are tightened correctly, and check that the handle of the battery cut-out switch is in the
"ON" position (for further information please refer to chapter "ELECTRICAL EQUIPMENT")
- do not use water pressure and temperature higher than 100 bar and 80° C respectively
- keep the washing nozzle at not less than 20 cm from the surface being cleaned
- do not insist with the jet on one point only but wash with wide movements.
- take care not to turn the jet directly on identification plates in order not to damage them
- After washing, carefully dry the glass screens and the rear-view mirror.
• CATALYTIC DEPURATOR (on request)
If the exhaust is excessively smoky, eliminate the cause by taking the required
action on the engine.
If this problem has lasted for a long time, the catalytic depurator must be
disassembled from the machine and cleaned inside simply by immersing it in
warm soapy water.
It must then be rinsed carefully and left to dry. DO NOT USE detergents or
solvents.
In any case, such cleaning must be performed at intervals of no less than 200
hours.
