Low pressure gauges can very easily be over pressured if not careful.
Please take caution when applying pressures.
Do NOT exceed the safety pressure limit ( 3500 psi / 235 Bar ).
This pump is not designed to be used in explosive or corrosive environments.
Do not switch between pressure and vacuum mode under pressure. Make sure you
have vented the pressure and opened the isolation valve before switching to vacuum.
Over tightening connectors may cause damage.
Pump should be stored in a dry/clean environment.
Additel is not liable for any safety problems or damages caused by misuse or
incorrect operation.
Do NOT hold pressure above 1000 psi for more than 4 hours.
All moisture and contaminants should be cleaned out of the liquid isolator before
creating a vacuum. This is accomplished by venting the pump when at high pressure.
For the least risk in contamination of the reference gauge, the DUT should be
installed to the pressure port which is closest to the vent valve.

Problem
Cause
Solution
Hand pump will not generate pressure
It is difficult to increase pressure
Hard to use fine adjust
Not easy to turn fittings
The isolation valve is not open
B. The O-ring seal is loose or damaged
D. Internal tubing is dirty.
B. The gauges are not tightened.
D. The connector type is mismatched to the gauge pressure port.
A. Too much force was previously applied.
.
C. The connector type is mismatched to the gauge pressure port.
A. Vent valve is not closed.
C. P/V selector is in the wrong position
A. The isolation valve is not closed.
C. The O-ring seal is aged or frayed.
E. Air route is blocked/dirty
B. The threads have no lubrication
.
.
.
Open the isolation valve
Replace O-ring seal.
Disassemble and clean (Request diagram).
Tighten the reference gauge and / or the gauge under test
Use the correct adaptor.
Do not over tighten. Hand tight is sufficient.
.
.
Use the correct adaptor.
Close the vent valve.
Pressure : Pull P/V selector out; Vacuum : Push the P/V select or in.
Close the isolation valve.
Pressurize to high pressure and release pressure quickly via the vent valve
Lubricate the thread
Replace O-ring seal.
