Draining (fig. 1)
- The tank is drained through plug (c) on the lower part of the tank.
Topping up (fig. 1)
- Fill with the specified oil through the opening of the plug (a) . See the Table of
LIQUIDS AND LUBRICANTS (references and capacities) in this Manual for oil
type and capacity.
Hydraulic circuit oil. Types and operating temperatures
VG32 for environmental temperatures usually below 10ºC ( 50 ºF)
VG46 for environmental temperatures between 10 ºC and 40 ºC (50 ºF and 104 ºF)
VG68 for environmental temperatures usually above 40ºC (104 ºF)
Oil Strainer: Clean (fig. 2).
There is an intake filter located on the interior of the tank in the hydraulic circuit. This is a
metal filter which should be cleaned every time the hydraulic oil is drained.
- To do so, remove the 6 screws (d) from the plate
- Before assembling, check the condition of the seal and replace if necessary.
Dispose of used oil in authorized waste disposal centres.
 Hydraulic hoses
All the hydraulic hoses should be replaced at least every 6 years.

Hydraulic system safety valves: adjustment (fig. 3, 4)
There are two safety valves for preventing overpressure: one on the steering circuit
and one on the operating circuit. The first is located on the hydraulic steering
(e) and
the second on the pump outlet (f) . These valves are set to the correct pressure in the
factory, but their trim should be checked regularly and adjusted accordingly.
The adjustment should be carried out by personnel with experience of hydraulic systems
and with the appropriate tools. The pressures should never exceed those given in the
section
TECHNICAL SPECIFICATIONS in this Manual.
Hydraulic steering valve (fig. 3).
- Remove the plug (e)
- To increase the hydraulic pressure turn the interior screw clockwise using a screw
driver. To reduce the pressure, turn the interior screw in the opposite direction.
Operation circuit valve (fig. 4).
- Remove the seal.
- Remove the plastic cover
(f) .
- Loosen the lockrnut.
- To increase the hydraulic pressure turn the screw clockwise using an Allen key.
To reduce the pressure, turn the interior screw in the opposite direction.
