Creating Pressure - SIKA P40.2 Notice D'utilisation

P40.2 / P60
CAUTION! Damage to valve stop!
If put under too much strain the stop and the hand pump will be damaged.
 Only continue to tighten the valves (the fine adjustment, pressure relief and switch
valves) by hand, once the stop has been reached.
Before creating pressure or vacuum consider:
Before you create pressure or vacuum with the hand pump you should check for the follow-
ing requirements:
 The reference gauge is connected to the hand pump.
 The test item is joined to the pressure hose with the correct adapters and seals.
 All pressure connections are correctly in place, so that they resist pressure.

5.1 Creating pressure

As the counter pressure of the test item increases, more energy is needed for the pumping
movements of the hand grips.
CAUTION! Damage to test item!
Adhere to the maximum pressure of the test item!
Only create an admission pressure with the hand grips that is lesser than the necessary
testing pressure. Following this carefully increase the pressure using the fine adjust-
ment valve.
In practical use the following operation methods have proved themselves to be useful:
Operation with one hand:
20 bar can be built up safely
and smoothly.
Above 20 bar, creating pres-
sure becomes progressively
more difficult.
Technical changes reserved.
Operation with both hands:
35 ... 40 bar can be generated
quite quickly.
Above 40 bar the pressure
should be increased with the
fine adjustment valve.
Operation
Pumping against a base:
50 ... 55 bar can be created in
this way.
In this process it is important
that the lower hand grip is
placed on a non-slip base.
