Warnings and cautions
Be careful when using with small chamber or low pressure gauges
not over pressure the gauges.
Do not exceed 1500 psi for 917 ( 2000 psi for 918 ) safety limit.
Do not shift between pressure and vacuum mode while the pump is
under pressure. Open the vent valve as well as the bypass valve
before switching between vacuum and pressure modes.
Do not over tighten gauges or connectors. Lightly hand tight is sufficient.
Store the pump in a dry non-corrosive environment.
Additel is not responsible for problems or damage resulting from
improper use or operation of the equipment.

Troubleshooting
Problems
Hard to use pressure lever
Hard to pressurize
Hard to use fine
adjustment handle
Fittings do not turn into
pump easily
Solutions
Causes
The isolation valve is not open.
Open the isolation valve.
A. Release valve is not closed.
Close the release valve.
B. The sealing ring is broken or loosen.
Replace sealing ring.
C. P/V selector is in wrong position.
Pressure: pull it out; Vacuum: push it in.
A. The isolation valve is not closed.
Close the isolation valve.
B. The gauges is not tightened.
Tighten the reference gauge or the gauge under test.
C. The sealing ring is aged or frayed.
Replace sealing ring.
D. The connector type is unmatched.
Use the right and suitable adapter.
E. Particle is blocking the air route.
Pressurize and release pressure quickly several time to try and blow the particle out.
Disassembly and cleaning may be necessary.
A. Likely tightened too much!
Do not apply too much force to close the fittings and gauges.
B. The new pump is not smooth.
The new pump needs time to abrade.
C. The threads have no lubrication.
Lubricate the threads.
