Cause of fault

If the pressure or vacuum cannot be generated correctly or if the set
pressure or vacuum does not stay stable, this is likely to be caused by the
incorrectly positioned or selected sealing gaskets. Please also check
whether any adapters used on the test specimen side have been
tightened sufficiently to eliminate leaks.
Before assuming there is a leak in the hand test pump: first of all, check if
the relief valve is closed and if the pressure / vacuum change-over switch
is correctly positioned and has not come to rest in a "centre position".
If the hand test pump has not been used for a longer period of time, the
first lift may be somewhat sluggish. This effect will disappear again during
further operation.
By no means apply any force to the operating elements of the hand test
pump.
Never connect an external pressure supply system to the test pump.
