The Challenger CLHMR40-IOM-A is the direct-replacement installation and operation manual for the Challenger lift it came off of — the genuine 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: CLHMR40-IOM-A
• Brand: Challenger
• Type: Genuine OEM installation and operation manual

Fasteners and small hardware fit by more than just thread size. Grade matters — a hardware-store bolt in a load-bearing spot doesn't have the strength of the rated fastener it replaced — and length, head type, and locking feature all have to match. Anchor bolts especially are engineered for the load and the concrete. Grabbing whatever's in the bin for a structural fastener is exactly the kind of shortcut that fails under shock load.

Replacing your installation and operation manual

Replacing an airline is quick work — cut the new line to length, seat it fully in its push-connect or threaded fittings, and route it clear of pinch and chafe points. Then pull the lock release and confirm the air actuates every pawl cleanly and together. Since the air side controls the locks, the step-by-step guide is worth a look before you rely on it. 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

The miscellaneous check: airlines free of cracks and leaks with a clean lock release; decals present and legible; hardware tight, correct grade, and rust-free; air pressure steady; the correct manual on hand; no missing pins, clips, or guards. None of these carries the car by itself, but together they're the difference between a lift that's merely running and one that's actually right.

Parts commonly replaced at the same time

Small parts are a good moment to catch up on the rest — decals that are fading, hardware that is due, accessories that pair with what you are buying. We keep the parts breakdown for your model, so one call can round out the order and save you a second wait.

Safety notes

Small parts still matter on a lift. Whether it is a decal an inspector checks for or an accessory that has to be rated for the load, use the correct item for your model and install it the way the manual specifies. Cutting a corner on a small part is still cutting a corner on a lift.

Before you order

A quick prep before ordering: model, serial, and what the part is for. Even minor components come in model-specific versions, and the right one depends on details on your data plate. Call and we will confirm before anything ships.

Ordering the right revision

Before this goes in the cart, grab two things off your lift: the model number and the serial number, both on the manufacturer's plate. The serial matters more than most people expect — lift makers revise components between production runs without renaming the lift, and the run your serial falls in determines which revision of this part is correct.

If you are working from a failed part rather than a plate, measure what you have and photograph how it mounts. Send that to us along with the lift brand, and we will check it against the same parts breakdowns our own techs use in the field before you commit to the order.
