Before driving any vehicle onto the lift, perform a quick visual sweep:
The lift utilizes a primary load nut to raise the vehicle and a secondary safety nut running just below it. If the threads on the primary load nut wear down past a safe threshold, the load automatically transfers to the safety nut, and an electrical safety switch triggers, preventing the lift from rising further.
Electronic or mechanical cable synchronization (depending on the specific DS2 variant generation).

| Symptom | Likely Cause | Suggested Solution | | :--- | :--- | :--- | | | The lift nut on the slave column is worn or misaligned, causing it to jam on the spindle. | Inspect the lift nut for wear. Ensure the clearance between the primary and secondary nuts is correctly adjusted. | | Lift does not operate after servicing | A safety interlock mechanism, such as a limit switch or an engagement pawl, may be incorrectly positioned. | Check all safety interlocks. On some models, a pawl that engages at the lowest point must be manually retracted before the lift will move upward. | | Intermittent operation / some relays not working | Electrical issues are common in older M&E models. Corroded contacts, failed relays, or faulty limit switches are likely culprits. | Test relays and sensors individually. Clean all electrical contacts in the control cabinet. Isolate and test the motors by connecting them directly to power to rule out major component failure. | | Unusual noises or jerky movement | Worn chain guides, a loose SPZ belt, or dry bearings can cause mechanical noise. | Inspect and replace chain guides and belts as needed. Lubricate all bearings and moving joints per the service manual schedule. | | Lift does not go up or down | The safety lock pawls have engaged, preventing movement. This often happens at the lift's lowest position. | Safely access the pawls at the base of each column and manually retract them using a pry bar or similar tool before attempting to operate the lift again. |
Based on numerous first-hand accounts, the most reliable method is to contact . Multiple users on automotive forums have reported that the company is surprisingly helpful, even for lifts that are several decades old.
The Stenhoj DS2 is a remote control receiver unit used primarily in material handling and industrial automation. It interprets radio signals from a transmitter to control relays, motors, and safety circuits. Without the manual, users risk: Before driving any vehicle onto the lift, perform
Press the "Down" button. Keep a continuous eye on the vehicle to ensure it descends smoothly and evenly.
The manual identifies this as a possible "feedback loop failure." Check the emergency stop auxiliary contact—if it’s open, the DS2 will suppress outputs even with a valid radio signal.
