When a vehicle is stuck 6 feet in the air and the lift won’t respond to the down button, panic is the worst thing you can bring into the bay. A proper lift emergency lowering procedure exists on almost every two-post, four-post, and scissor lift on the market, but most shop owners and home garage users have never had to find it, read it, or practice it until the moment they actually need it. We’re Auto Lift Services, based in Ames, Iowa, and we install and service lifts across the state, which means we get the panicked calls. Before you call anyone, here’s what you need to know about lowering a stuck lift safely.
Search by lift brand and model to find the manual release valve, cable, or hydraulic part that matches your exact unit before you attempt an emergency lowering procedure.
Why Lifts Get Stuck in the First Place
Most emergency lowering calls trace back to one of three causes: a failed solenoid valve that won’t open to release hydraulic pressure, a broken or badly frayed cable on a two-post lift that trips the built-in safety lock, or a control panel that’s lost power entirely due to a tripped breaker or dead relay. On four-post and scissor lifts, a jammed safety latch or a bent lock bar is another common culprit. None of these situations mean the lift is unsafe to lower — they mean the *normal* down cycle is interrupted, and that’s exactly what an emergency lowering procedure is built to handle.
We’ve walked customers through this exact scenario more times than we can count, usually over the phone while they’re standing next to a car that’s been stuck since lunch. The good news is that almost every commercial lift — Rotary, Challenger, BendPak, Atlas — ships with a manual override built into the hydraulic system specifically for this situation. The bad news is that finding it under stress, without ever having located it before, is harder than it should be. That’s why we tell every customer during installation to locate their manual release valve on day one, not day 100 when something breaks.
The Standard Lift Emergency Lowering Procedure
The general lift emergency lowering procedure follows the same basic sequence across most brands, though exact valve locations vary. First, clear the area — get everyone away from underneath and beside the vehicle, and make sure nothing is positioned to be crushed or knocked over as the lift descends. Second, cut power to the unit at the disconnect or breaker so nothing engages unexpectedly mid-lower. Third, locate the manual lowering valve, usually a small brass or steel valve near the power unit or hydraulic cylinder, and slowly crack it open using a wrench or the tool specified in your owner’s manual.
The key word is slowly. Opening the valve too fast dumps hydraulic fluid quickly and can cause the vehicle to drop hard, which is dangerous for both the vehicle and anyone nearby. A controlled emergency lowering procedure brings the lift down in a steady, even motion, and you should be ready to close the valve immediately if anything looks wrong — an odd tilt, a grinding noise, or resistance that wasn’t there before. If at any point during the lift emergency lowering procedure something doesn’t feel right, stop and call a technician rather than pushing through. A stuck lift is an inconvenience. A dropped vehicle is an insurance claim and potentially an injury.
Two-Post Lifts: Cable and Safety Lock Issues
Two-post lifts add a wrinkle to any lowering procedure because most models use a cable-and-pulley system tied to a mechanical safety lock on each column. If a cable breaks or stretches unevenly, the safety locks can engage on one side and not the other, leaving the lift cocked and refusing to move. In this case, the emergency lowering procedure isn’t just about releasing hydraulic pressure — it may also require manually releasing the safety latch on each column using the release handle, usually located near the top of the post.
This is where we tell people to be the most careful. Releasing a safety lock on a two-post lift with a compromised cable means there’s less holding the vehicle up than there should be. We’ve been called out to more than one Iowa shop where a rushed attempt to force a stuck lock resulted in a lift dropping several inches unexpectedly. Our advice is simple: if you suspect a cable failure rather than just a hydraulic or electrical fault, don’t attempt the full lowering procedure yourself. Get eyes on the cables first, even if that means waiting an extra hour for a tech to arrive.
Four-Post and Scissor Lift Considerations
Four-post lifts and scissor lifts behave differently under a stuck condition because the load is distributed across a wider platform rather than concentrated on two columns. The emergency lowering procedure on these units typically centers on the safety lock bar or ratchet mechanism that automatically engages at set height intervals. If the lift won’t lower, check first whether a lock pin or bar is simply engaged and needs to be manually released before the hydraulic valve will do anything useful.
Mobile column lifts and scissor lifts used for alignment work sometimes have a synchronized lowering system that requires all columns or both sides to be released together, not one at a time. Releasing only one side of an unsynchronized system is one of the more common mistakes we see, and it can cause the platform to tilt. If your setup has multiple independent lock points, work through the manufacturer’s documented sequence rather than guessing at which valve to open first.
What Not to Do During an Emergency Lowering
Never use tools not specified for the job to force a valve or lock open — stripped valves and bent lock bars turn a fixable problem into an expensive one. Never have someone standing under or near the vehicle while you work the release, even briefly. Don’t assume the lift will lower evenly if you’re not sure both sides are releasing together; watch it the entire way down and be ready to stop immediately. And never skip cutting power first — an electrical fault that’s actively cycling the motor while you’re working the manual valve is a hazard we’ve seen cause real damage.
When to Stop and Call a Professional
If you’ve gone through the documented lift emergency lowering procedure and the lift still won’t budge, or if you’re seeing signs of cable damage, bent components, or fluid leaking under pressure, stop and call someone who works on lifts for a living. This isn’t about protecting a sale — it’s that some failures genuinely aren’t safe to work through without the right tools and experience, and we’d rather talk you through it over the phone or send a tech than have you improvise a fix on a piece of equipment holding several thousand pounds off the ground.
Preventing the Next Emergency
The best lift emergency lowering procedure is the one you never have to use. Annual inspections that catch worn cables, corroded valves, and weak hydraulic seals before they fail are far cheaper than an emergency call, and they keep your bay productive instead of down for a day. We also recommend every shop keep a laminated copy of their specific lift’s manual release instructions posted near the unit — when the pressure’s on, a wall chart beats trying to remember a video you watched once. If you’re not sure where your lift’s manual release is located, that’s worth finding out today, not during the next breakdown.
