1.1 Operating Instructions
This equipment exhausts gas as part of its operating cycle. Wear hand, ear, and eye protection, and
keep sparking devices and open ames away.
1.2 Installation
For nal assembly over stem to valve: to lift the operator only, use lifting eyes with a 3 leg sling and
one shortening hook.
Excess operator travel can cause damage to end of stroke (trigger) valve if over-travel occurs and the
trigger interferes with the component. The operators mechanical end-stops are preset at the factory
for 90° travel.
1.3 Start-Up Checks
If unit has a fail or ESD (Emergency Shut Down) position, the fail-safe or ESD controls may have to
be temporarily disabled, bypassed or overridden by AUTO/MANUAL selector to prevent inadvertent
valve operation.
1.4 Maintenance and Operational Testing
De-pressurize operator before attempting to service power gas lter, check tank uid level or check
manual operation of handpump.
1.5 End of Stroke Valve Instructions
Changing operator travel can cause damage to end of stroke (trigger) valve if over travel occurs and
trigger strikes component.
1.6 Operator Maintenance
Gas/Hydraulic tanks should be drained and ushed if uid is contaminated with scale, rust,
particulates, water, foam, or etc. Flush only with hydraulic uid. Rell with ltered uid.
