The Challenger ZRJ7X-IOM-A installation and operation manual is the direct replacement for the Challenger lift it came off of. This is the genuine Challenger part — same fit and same working specification as the one already on your lift. Ordering the Challenger installation and operation manual from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.
Specifications
- Part number: ZRJ7X-IOM-A
- Brand: Challenger
- Type: Genuine OEM installation and operation manual
An airline is only interesting because of what it controls — usually the lock releases and, on some lifts, pneumatic lock engagement. Shop air runs through it to pull the pawls so the lift lowers evenly. When the line cracks, kinks, or a fitting leaks, the lift may not release all its locks together, which means it comes down cocked. A small pneumatic problem shows up as a lock-timing problem.

Replacing your installation and operation manual
Most small-parts replacements go the same way: confirm the new part matches the old in size, rating, and function, install it in the correct location, and verify it does its job before the lift goes back to work. It's simple, but matching the right part is what keeps the lift correct. The full procedure covers the details. Not sure on the procedure? Find your lift in our parts lookup or call and we will walk you through it.
Find the right part for your lift
The surest way to get the right part is to work from your lift's own breakdown. open our Challenger parts lookup, choose your model, and every part is mapped on the drawing with its number and price. If you cannot find the model plate, our guide to finding your model number explains where each lift type hides it, and our phone line is open if you want a hand.
Signs it's time to replace it
Give the lift a general walk-around for the small stuff that gets missed. Look for missing pins, clips, and retainers; loose covers and guards; chafed wiring or tubing; and anything rattling that shouldn't. These little items don't stop the lift, but a missing retainer or an unguarded pinch point is how a small oversight turns into an injury or a bigger failure down the line.
Parts commonly replaced at the same time
One order can cover more than one need. When you call, we can look at the full parts breakdown for your model and flag the companions worth adding now — the wear items and safety parts that tend to come due together. It saves freight and a second wait.
Safety notes
A lift is a system, and even its minor parts are specified for a reason. Order the right one for your model, install it as the manual directs, and keep safety and instruction decals legible. We would rather confirm the detail now than have you find out at inspection time.
Before you order
Ordering tip: have your model and serial ready even for the small parts, since fit and specification still vary by lift. Tell us what you are trying to solve and we will confirm the right item — a quick check now beats a wrong order and a second wait.
Check your lift's serial before ordering
The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift.
Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
