 Adjusting the safety valves (fig. 1, 2)
There are two safety valves to avoid over pressures in the steering circuit and the load
handling systems.
a. Steering circuit safety valve
b. Load handling system safety valve
The first is located on the hydraulic steering and the second is externally connected to
the distributor.
These valves are set at the correct working pressure in factory, but the settings need to be
checked periodically and adjusted if necessary. This work must only be done by trained
mechanics with knowledge of hydraulics and with the appropriate tools. Pressures must
never exceed the limits indicated in the
SPECIFICATIONS section of this manual.
- Hydraulic steering valve: Remove the cap by unscrewing it and turn the internal
screw with a screwdriver in a clockwise direction to increase the hydraulic
pressure and anti-clockwise to reduce it.
- Circuit pressure regulation valve: Remove the plastic cover, then loosen the
counter-but and turn the screw a clockwise direction to increase the hydraulic
pressure and anti-clockwise to reduce it.

Hydraulic hoses
All hydraulic hoses must be changed at least every 6 years.
11.- Electrical circuit

Battery
The battery is located in the engine compartment to the right.
Check that the battery has no external damage, lifted plates or electrolyte leaks.
Check the electrolyte density. It should have a value of between 1.27 and 1.28.
Clean the battery terminals of rust.
Apply dielectric grease or vaseline on the positive terminal to protect it from rust.

Battery disconnector (fig. 3)
There is a battery disconnector on the negative terminal (-).
Disconnection of the battery is recommended during repairs to the electrical installation,
soldering and long storage periods.
WARNING
Never charge the battery when it is mounted on the vehicle.
