The mode of action of the quick stop:
The quick stop makes it possible to uncouple a hydraulic cylinder that is under load. Jerking
open the handwheel of the drain valve on the hand pump causes the valve in the coupling plug
on the cylinder side to close. At the same time, the coupling sleeve on the hose side is relieved
and can be uncoupled.
With the distributor valve ID 364380 connected in between, close the valve belonging to
the hydraulic cylinder by turning the handwheel to the right. Open the drain valve on the hand
pump by turning it to the left.
Then, as mentioned above, trigger the quick stop by jerkily actuating the handwheel on the
distributor valve.
When reconnecting, open the handwheel of the distributor valve. Close the handwheel of the
drain valve on the hand pump. Execute a few pump strokes. The quick stop is cancelled so that
normal lifting or lowering (slow opening of the valves) is possible.

Accessories

Accessories have an M 42 x 2 thread matching the piston rods of the ERGS 50 hydraulic
cylinders and are designed for the corresponding lifting force.
NOTE!
Make sure that all threads are screwed in to prevent the risk of accidents and to
avoid damaging the threads.
When fitting the accessories, hold the piston rod with the hook spanner.
Using the lifting claw
Unscrew the protective ring on the ERGS 50 hydraulic cylinders. To do this, screw on the lifting
claw so that the smooth side faces the piston rod. Fit the piston rod with a foot plate and place
the cylinder upside down on the foot plate. This allows low-lying loads of up to 137kN to be
lifted.

Bleeding the hydraulic system

If the piston rods extend jerkily after several pump strokes, i.e. at intervals, the system must be
bled. To do this, extend the hydraulic cylinder completely. Place the hydraulic cylinder on the
floor. Hold the hand pump higher or place it on the workbench. Pay attention to the position of
the maximum pressure hoses. The air bubbles must be able to rise easily to the top of the hand
pump.

Maintenance

Keep joints and pistons on hand pumps and hydraulic cylinders clean and grease them from time
to time. Allow piston rods to retract into the hydraulic cylinders after use to prevent rusting. With
frequent use, we recommend changing the oil annually.
4.15

Oil check and oil filling

To check the oil level, there is an oil sight glass on the opposite side of the hand pump to the
hose. The pump must be in a straight position for inspection.
Please pay attention to cleanliness when filling the oil!
With the hand pump, remove the oil filler plug and empty the contents. If necessary, rinse out
the oil container (petroleum ether or white spirit).
The DPH 4018 hand pump is filled with 2,500 cm³ of oil. Only pour in the prescribed amount of oil
because a certain amount of air is required in the oil tank for this pump to function.
Never pour in brake fluids, engine oil, petrol or similar fluids.
After filling, screw the screw plug back on tightly. For bleeding, see 4.13.

Hydraulic oil / operating medium

The H 1 and H 2 lifting sets are designed and tested for the WEBER hydraulic oil part no.
1057565F. This oil has a particularly high degree of purity and also works without problems in
temperatures as low as -20° C. For more information and alternative hydraulic oils, see Chapter 8
