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 uidller 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.
