Hydraulic uid cooler
The oil radiator is installed behind the diesel engine (Fig. 82).
The left part contains hydraulic oil; the right part is intended
for cooling for the engine. Should the loader get too hot dur-
ing long drives on the road or at high outside temperatures,
check whether the fan‘s V-belt is taut and in good condition
and whether the radiator air ow is blocked.
Ventilation lter / hydraulic uid ller neck
The ventilation lter is located on the hydraulic uid reser-
voir item 1 (Fig. 83). It ensures that the hydraulic reservoir
is ventilated and exhausted when the hydraulic uid level
uctuates. The air lter contains a lter element which pre-
vents dust and dirt from penetrating and oil spillings from
escaping. The air lter has a valve that keeps the reservoir
pressure at approx. 0.5 bar (7 psi). This pressure will escape
if the hydraulic uid ller neck is opened.
Replace the ventilation lter after 1000 operating
hours.
