Hydraulic fluid
The hydraulic-fluid tank is located on the right-hand side of the
truck.
Check the fluid level on the fluid sight-glass, with all hydraulic pis-
tons in the bottom positions.
Top up the hydraulic fluid as necessary. See the Specification for
the oil grades.
If the truck has an oil-cooled wet disc brake system, any hydraulic
oil used for topping-up should contain Lubrizol additive which is
necessary for good performance of the brake system. See Grop
90, Oil and luricant recommendations
The additive is not consumed during normal operation and must
only be added at oil change and refill. Lubrizol may be ordered
from Kalmar Service department.
Hydraulic oil filter
The high pressure filter for the hydraulic oil must be changed at
the intervals specified in the lubrication chart. In addition, the filter
must always be changed whenever work has been carried out on
the hydraulic system.
The filter contains a by-pass valve which opens at a counter pres-
sure of 7 bar in case the filter should be clogged by impurities.
1. Clean the outside of the filter and the area around it.
2. Place a vessel under the filter to collect any spillage.
3. Empty the filter bowl by unscrewing the drain plug.
4. Unscrew the filter bowl.
5. Slide off the filter cartridge.
6. Replace the two O-rings between the filter head and the filter
bowl.
The O-rings are included with the filter cartridge.
Moisten the O-rings with hydraulic fluid prior to fitting.
7. Remove the filter cartridge from its packaging and immedia-
tely fit it.
8. Clean the filter bowl carefully and half fill it with hydraulic fluid.
9. Screw back the filter bowl in position.
10.Start the engine to purge the system of air, and check that the
filter does not leak.
Breather filters
Two breather filters on top of the hydraulic tank protect the hy-
draulic liquid from impurities as air needs to enter and leave the
tank. The filters are of spin-on type.
IMPORTANT!
Systems with separate tank for the brake system:
The hydraulic fluid for the brake system must never
contain any additives.
WARNING!
Hydraulic fluid is chemically
aggressive. Avoid extended contact with the skin.

IMPORTANT!
The filter has an arrow on it indicating
the direction of the flow. The filter must
therefore be fitted so that the arrow
points in the direction of the flow.
