The Stenhøj DS2 is a classic electromechanical two-post automotive lift known for its durability and "asymmetric" arm design, which allows for better door opening clearance on vehicles. Because these lifts are often serviced over decades, the manual is essential for proper installation and the maintenance of its screw-and-nut drive system.
Below is a report summarizing the critical sections typically found in a Stenhøj DS2 user and installation manual. 1. Technical Specifications
The DS2 series generally covers several weight capacities, with the DS2 2.5 (2500kg) and DS2 3.0 (3000kg) being the most common.
Drive System: Twin-motor electromechanical drive using a "spindle and nut" mechanism. Lifting Height: Approximately 1900mm–2000mm.
Voltage: Usually requires a 3-phase 400V supply, though some variants exist for 230V. 2. Installation Requirements
Proper setup is vital to prevent structural failure or uneven lifting.
Foundation: A level concrete floor is mandatory. The foundation must be flat, horizontal, and meet the minimum depth specifications (typically 150mm–200mm of reinforced concrete).
Alignment: The two posts must be perfectly parallel. Installers must check for "outward leaning" and ensure the motor axis is parallel to the spindle axis.
Anchoring: Use heavy-duty chemical or mechanical anchors. The manual specifies the exact torque settings for these bolts. 3. Operation and Safety
Arm Placement: The DS2 features telescopic "swing arms." Users must use all four arms only at the lifting points recommended by the vehicle manufacturer.
Safety Nut System: Stenhøj lifts utilize a "load-bearing nut" and a "safety nut." If the load nut wears down significantly, the safety nut "catches" the carriage, and the lift will typically lock out to prevent further use until repaired.
Synchronization: Since each post has its own motor, they are synchronized via a cable or electronic bridge. If the carriages become unlevel, the safety circuit will stop the lift immediately. 4. Maintenance Schedule
To ensure longevity, the manual outlines a strict maintenance routine:
Daily: Check the lifting pads for damage and ensure the safety locks engage.
Monthly: Grease the spindles (main screws) and check the "wear gap" between the load nut and safety nut.
Annually: Conduct a full safety inspection, check electrical connections, and verify the integrity of the base anchors. Resources for Manuals
If you are looking for a physical copy or PDF, you can often find them through these types of platforms:
Official Distributors: Companies like Stenhøj (AutopStenhøj) provide technical documentation for current and legacy models.
Manual Repositories: Sites like Scribd often host archived PDF versions of the DS2 installation and parts manuals.

Stenhøj 2-Post Lift Installation Manual | PDF | Elevator | Concrete
The fluorescent lights of the Solrød repair shop hummed with a sound that only tired men could hear. Outside, the Danish winter was painting the windows white with sleet. Inside, Elias, a mechanic with grease permanently etched into his knuckles, stood before the beast.
It was a Stenhoj DS2.
To the uninitiated, it was just a heavy, industrial scissor lift—a piece of garage equipment used to hoist two-ton vehicles into the air. But to Elias, the DS2 was a legend. It was the "Old King" of the shop, installed sometime in the late 1980s, built out of thick Danish steel before the era of planned obsolescence.
And right now, the King was dead.
"I can't find it, Elias," said Mikkel, the shop apprentice. He was sitting cross-legged on the cold concrete floor, surrounded by a sea of scattered papers. "I’ve checked the server. I’ve checked the backup drives. I even called the distributor in Kolding. They said the DS2 is so old their digital records don't go back that far."
"The manual," Elias muttered, wiping his hands on a rag that was dirtier than his skin. "We need the manual, Mikkel. Not the generic brochure. The service manual. The one with the hydraulic schematics."
The lift was stuck in a safety lockout. The ramps were raised, but the locking mechanism hadn't disengaged, meaning the car currently trapped atop it—a very expensive, very impatient customer’s vintage Porsche—was effectively a permanent fixture of the garage ceiling.
"Someone must have it," Mikkel insisted. "Or it's gone. The internet has nothing. Just dead links and Russian spam sites."
"Check the archive room," Elias said, jerking his thumb toward a back door that was rarely opened. "Third drawer. The locked one. The key is in the coffee tin."
Mikkel scrambled up and disappeared into the gloom of the back office. Elias turned back to the DS2. He ran a hand along the cold steel of the scissor arms. It was solid, heavy. Unlike the newer, lighter lifts, the DS2 didn't whine; it growled. But today, it was silent, a steel trap.
Ten minutes passed. Then twenty.
Elias was beginning to contemplate the embarrassing prospect of calling the fire department when Mikkel returned. He wasn't carrying a PDF printout. He was holding a binder.
It was thick, encased in a faded blue plastic cover that had cracked along the spine. The corners were frayed white, and a layer of dust puffed into the air as Mikkel set it down on a workbench.
"Found it," Mikkel breathed. "Under a stack of tax returns from 1994."
Elias picked it up. The weight was substantial. On the cover, in simple, typewriter-style font, it read: STENHØJ DS2 - INSTALLATION, OPERATION & MAINTENANCE MANUAL.
"Open it," Elias commanded.
Mikkel undid the rusty clamps. The paper inside was yellowed, smelling of old pulp and ozone. They bypassed the "Safety Instructions" and the "Warranty Information" (which had expired twenty years ago) and went straight for Section 4: Hydraulics.
"Here," Elias said, pointing a grease-stained fingernail at a diagram. It was a technical drawing of the hydraulic block. "The pilot valve. Look at the diagram for the lowering sequence."
They huddled over the binder. The manual was a masterpiece of industrial clarity. There were no glossy photos, only crisp line drawings and dense, translated text. It showed the flow of oil, the pressure ratings, and the specific sequence of the solenoid valves required to disengage the safety lock.
"See that?" Elias tapped the page. "To lower it manually, you have to bypass the solenoid before you release the hydraulic pressure, or the lock pawl binds. We’ve been doing it backward."
"The new guy on the phone said we just hit the button," Mikkel said, frowning.
"The new guy has never seen a DS2," Elias grunted. "This thing was built when safety meant 'heavy steel,' not 'software override.' The manual says we need to manually actuate the relief valve while applying counter-pressure."
Elias grabbed a wrench. He didn't look at the lift; he looked at the manual. He traced the line from the diagram to the physical machine. "Page 14, Figure B. The manual override hex key."
They walked to the side of the lift. Hidden behind a black rubber grommet was a hex bolt. According to the manual, turning it counterclockwise would bleed the pilot pressure.

A: According to page 18 of the manual, hold the programming button for 10 seconds during power-up until the LED flashes red five times. This erases all paired transmitters.
The DS2 is a dual-channel, transformer-balanced microphone preamplifier and direct injection (DI) box, typically housed in a rugged 1U rack chassis. Produced in limited quantities during the late 1980s and early 1990s, it was Stenhoj’s answer to the growing need for a portable, high-headroom front end for both studio and broadcast applications. Its hallmark is a discrete, class-A circuit path that delivers a punchy, harmonically rich character—often compared favorably to vintage Neve or API, but with a distinctly Scandinavian clarity.
