8.1. Check oil level hydraulic tank
Check the oil level of the hydraulic tank every two months at normal working conditions.
To prevent measuring faults: Do not check the oil level when the oil is hot. The oil
temperature must be below 40°C (104F).
1. Make sure the truck stands on a horizontally flat
base.
2. Check the gauge (2) of the oil tank (1). The oil
level must be at approx. 80% of the gauge.
(Picture 8-1)
3. If necessary fill up the tank with hydraulic oil
through the filler hole (3).
4. Always use hydraulic oil of the same brand and
type. (Consult Spierings Kranen in case of
doubt).

Below the engine cowling near the steering housing is another
tank situated. (Picture 8-2) This tank is hydraulically supplied
with oil by the hydraulic pumps and is therefore always full. The
surplus on oil will be returned to the main tank. The oil level of
this tank does not need to be checked.
