WIKA Operating Instructions Comparison Test Pump Version 2.1 16
5.2.2 Filling in of hydraulic oil .
Open the high-pressure shut-off valve
Open the low-pressure shut-off valve
Turn in the spindle pump clockwise until it reaches the initial stop
Open the locking screw with the oil filling symbol on top of the basement
Fill in special oil (0.5 litre supplied, or available as accessory) via the tank opening, until the fill
level reaches the thread of the tank opening (approximately 250ml). The fill level must always be
observed.
Twist out the spindle pump counter-clockwise until it reaches the rear stop. The filling medium is
suctioned out of the tank into the system.
Close the tank opening with the locking screw
5.2.3 Venting of the system (after complete filling only) .
After initial filling, or after a complete oil change, air may be trapped in the system. The system should
be vented using the following procedure:
Open the high-pressure shut-off valve
Open the low-pressure shut-off valve
The test connections must be open
Twist out the spindle pump counter-clockwise until it reaches the rear stop.
Carefully pump using the initial pressure pump, while continuously observing the filling medium in
the open test connections. At this point, trapped air escapes toward the exterior by means of the
formation of bubbles. The initial pressure pump must be actuated until air bubbles no longer
appear.
Any oil escaping in the open test connections should be siphoned off, for example, with a nozzle.
