SERVICING AND INSPECTION
190
Checking the hydraulic uid level
The hydraulic oil reservoir is located on the left side of the
rear frame. To access it, open the engine enclosure (refer-
ence Section 10.7.1, pages 164-168).
Never let the oil level drop below the »Minimum«
mark on the dip stick.
When adding oil, never let the »Maximum« mark
on the dip stick be exceeded.
Oil cloudiness means that water or air is in the
system, which could damage the hydraulic pump.
Contact trained specialized personnel to eliminate
the fault. Do not drive the loader until the fault has
been eliminated.
Ventilation lter / hydraulic uid ller neck
The ventilation lter is located on the hydraulic uid reser-
voir item 1 (Fig. 90). 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.
