12 Servicing and Maintenance
For safety reasons, the operating pressure must be checked after approx. one month. Despite accurate factory settings and testing, the
max. operating pressure that can be achieved can change after start-up of the device. If there are any deviations from the tolerance
(operating pressure) specified in section 16, either readjust the pressure valve according to section 4, or contact an authorised dealer or
the customer service.
The first oil change should be carried out after six months upon completion of a pressure check. If the contact pressure deviates from the
nominal pressure specified in the operating instructions, the pressure valve must be adjusted by an authorised dealer or the customer
service.
The oil must be changed once per year. In case of frequent use or operation in particularly dusty
environment, oil should be changed every six months. Further, it is mandatory to clean the oil sieve in the oil container of the pump each
time the oil is changed.
12.1
Adding Oil to the Pump
Warning: Always add oil with cylinders fully retracted (extended if pull cylinders) or the system will contain more oil than the
reservoir can hold.
-
Remove vent/fill cap from reservoir ,
- Only fill the oil to approx. 2.0-2.5 cm below the upper edge of the oil container (depending on the size of the container),
- Remove air from system if necessary. See 8.3. Recheck oil level after removing air,
- Return vent/fill cap to proper position.
- Make sure no dirt gets into the oil reservoir or into the pump, as this will cause malfunction.
- To extend pump life and improve performance, lubricate the beam pin
A , cross pin B and piston head C regulary, using roller bearing
grease. See cover page.
13 Transport
13.1 WHE-1, and WHE-2 hand pumps
For transport, the lever and the bolting device has to be a locking position. The lever can be used as a carrying handle.
14 Troubleshooting
If the defects cannot be repaired, contact an authorised dealer or the service department.
