Qualified personnel
● The personnel who are charged for the installation and operation of the HTP1 must
hold a relevant qualification. This can be based on training or relevant experience.
The personnel must be aware of this operating manual and have access to it at all
times.
General safety instructions
● In all work, the existing national regulations for accident prevention and safety in the
workplace must be complied with. Any internal regulations of the operator must also
be complied with, even if these are not mentioned in this manual.
● Never use the hand pump together with an external pressure source. Do not attach
an external pressure generator to the hand pump.
● Do not use brake fluid or other aggressive media.
● Do not remove any attached components (test item, pressure hose, reference gauge)
when the hand pump is under pressure:
– Open the pressure relief valve before removing any of the components.
– Do not use Teflon tape to seal the pressure connections. Surplus Teflon tape can
enter the hand pump and damage it.
– Only use adapters and seals that are available as accessories.
– Non-pressurised storage: Only store the hand pump with the pressure relief valve
open. This ensures that no pressure can be built up by unintentional pumping
movements.
– Avoid external force of all kinds towards the hand pump and its operating
elements.
– Do not use the hand pump if it is damaged or defective.
