Operation
Pressure creation - operating steps

Switch on reference gauge and test item (if

necessary).

Close pressure relief valve:

•Turn the knob of the valve in a clockwise direc-
tion until the stop is reached.
 Set the switch valve to 'pressure':

•Turn the knob of the valve in a clockwise direc-
tion until the stop is reached.
 Create pressure:

•Push the hand grips together:
The pressure is built up.
•Repeat the pumping movements until the nec-
essary testing pressure has roughly been rea-
ched.
 Adjust the testing pressure.

The necessary testing pressure is precisely ad-
justed with the fine adjustment valve:
• Turn the handwheel in a clockwise direction to
increase the pressure.
• Turn the handwheel of the valve in an anti-
clockwise direction to reduce the pressure.
• Set the necessary testing pressure by turning
the wheel as needed.
Increasing pressure with the fine adjustment valve:
Alternatively, above ~ 20 ... 30 bar you can increase
the pressure with the fine adjustment valve.
 Turn the handwheel in a clockwise direction in
the direction of the 'pump body stop collar'. De-
pending on the pressure of the test item and the
setting of the handwheel, pressure increases of
max. 15 ... 30 bar can be achieved quite easily.
FINE ADJUSTMENT VALVE
When it is not under pressure the fine adjustment valve moves very freely. The wide
handwheel of the fine adjustment valve can be moved into the needed position very easily
using with the palm of the hand.
