In case of storage or longer system downtime, the

tank must always be filled sufficiently (dipstick

check – oil level between max and min).

Used hydraulic oil and oil deposits must be properly

disposed of. Hydraulic oil may not enter the ground

or be poured into drains. Hydraulic fluid spills must

be wiped up by suitable material immediately.

Filling oil

Carefully place the Hydraulic Power Unit in an upright position

(1), so that the vent is at the bottom and the unit flange on

the top. During fill-up, the air must be able to escape from the

tank through the oil drain plug (2). Remove dipstick (Fig. 9).

Place a funnel (1) in the oil filler spout (2) and add 3.9 liters

(238 in

) of hydraulic oil „HLP 46" with a measuring jug. Pour

in the oil slowly to avoid bottle-neck in the funnel. Since the

funnel cannot be sealed in the opening, oil leakage might

occur. After the filling process, remove the funnel and close

the oil drain plug (3) by turning it clockwise with an 8 mm

Finally, check the oil level with the dipstick once

more and add oil if necessary (refer to steps 6.1

and 6.2).

After the oil has been filled, remove oil residue from

the housing.
