TIP!
At high pressures, open the handle only slightly.
The handles can be compressed more easily the further the handles are closed. In
this way, you can create high pressures more easily and meter the pressure better.
â
The higher the pressure is, the less you should open the handles. In the event of
high pressures, avoid the initial position of the handles.
Hand pump operation
â
➀
Switch on reference gauge and test item
(if necessary).
â
➁
Close pressure relief valve:
– Turn the knob of the valve in a clock-
wise direction until the stop is reached.
â
➂
Create pressure:
– Push the hand grips together:
The pressure is built up.
–
Repeat the pumping movements until
the necessary testing pressure has
roughly been reached.
â
➃
Adjust the testing pressure.
The necessary testing pressure is preci-
sely adjusted with the fine adjustment
valve:
– Turn the hand wheel in a clockwise
direction to increase the pressure.
– Turn the hand wheel of the valve
counter clockwise to reduce the pres-
sure.
– Set the necessary testing pressure by
turning the wheel as needed.
â
➁
Releasing pressure:
Turn the pressure relief valve knob 1–2 rotations counter clockwise and wait
until there is no longer any positive pressure.
