Safety glasses must be worn at all times. Failure to do so may result in injury.

Persons attempting to use this should be knowledgeable in working with high-pressure gasses and mechanically inclined.

Read and understand ALL instructions prior to starting process.

Any questions, contact Ameritool at (315)668-2172.

1. Close release valve (D).
2. Turn T-Handle (A) out (counter clockwise).
3. Remove end fitting and/or stud from cylinder of gas spring. *Important: Note orientation of clearance hole on stud during removal of end fitting).
4. Thread adapter (B) onto gas spring cylinder. Do NOT overtighten.
5. SLOWLY turn T-Handle (A) clockwise until pressure reads on gauge (C), stop immediately. (Failure to do so may result in damage to valve core in gas spring and or pressure tool).
6. SLOWLY open release valve (D) to release gas pressure from spring. CAUTION releasing too much gas will permanently de-charge spring.
7. Once desired pressure is reached on gauge (C) close release valve (D).
8. Turn T-Handle (A) counter clockwise all the way out.
9. Open release valve (D) to release pressure from assembly. (Failure to do so may result in injury or damage to gauge).
10. Remove bleed off assembly from spring and repeat if necessary.
11. Re-assemble end fitting and place back into cylinder end. NOTE: the stud must be installed with the hold facing the valve core.

To calculate force of a gas spring use a known factor multiplied by pressure in spring (psi).

875 Series: .375 (8mm) rod: multiplier of .110

1165 Series: .562 (14mm) rod: multiplier of .248

1750 Series: .875 (22mm) rod: multiplier of .64

Example: 8mm diameter rod gas spring with 675 psi reading on gauge:

675psi x .110 = 74.25# of force fully extended
