Failure to do so could lead to property damage and/or serious personal injury.
IDENTIFICATION & INSPECTION IDENTIFICATION When ordering parts or requesting information or service on this lift, PLEASE REFER TO THE MODEL AND SERIAL NUMBER. This information is on a nameplate attached to the leg assembly. Replacement parts are available from a local Autoquip distributor. INSPECTION Immediately upon receipt of the lift, a visual inspection should be made to determine that it has not been damaged in transit. Any damage found must be noted on the delivery receipt.
DANGERS, WARNINGS & CAUTIONS Read and understand this manual and all labels prior to operating or servicing this lift. All labels are provided in accordance with ANSI Z535.4. DANGER! Do not work under lift without maintenance device! To avoid personal injury, NEVER go under the lift platform until the load is removed and the scissors mechanism is securely blocked in the open position. See the “Lift Blocking Instructions” section.
DANGERS, WARNINGS & CAUTIONS WARNING! NEVER stand, sit or ride on the lift! WARNING! All warning and information decals should be in place as outlined in the “Label Identification” section. If decals are missing or damaged, they should be replaced with new ones. Contact an Autoquip representative for replacements. CAUTION! When moving the lift, do not attempt to pick it up by the platform; it is hinged and could be damaged. Pick up from under the base frame ONLY.

LIFT BLOCKING INSTRUCTIONS 1. Remove all load from the platform. Never block the lift when loaded, only when empty. 2. Raise the lift platform sufficiently to install the maintenance leg. 3. Begin lowering the platform by activating the “DOWN” valve until the maintenance leg is captured by the socket on the underside of the platform and the locating disc on the base frame. Continue activating the “DOWN” valve five to ten seconds to relieve the air pressure in the air bag. 4.
INSTALLATION INSTRUCTIONS 1. Make sure installation area is clean before starting. 2. If the permanent air supply work is not complete, some means of temporary lines with an on-off device for the air supply should be set up for testing purposes. 3. Place the lift in the installation area. CAUTION! When moving the lift do not attempt to pick it up by the platform; it is hinged and could be damaged. Pick up from under the base frame ONLY. 4. Make temporary air connections.
OPERATING INSTRUCTIONS 1. Scissors lifts have a maximum lifting capacity (see “Specifications” section). The safety relief air valve has been factory set to open at a point slightly above the rated load and allows the air to bypass into the atmosphere. Lowering loads exceeding the rated capacity of the lift may result in excessive wear and damage to the lift. 2. This type of lift is designed primarily for in-plant applications and is furnished with constant pressure foot valve or hand valve controls.
ROUTINE MAINTENANCE Normally scissors lifts will require very little maintenance. However, a routine maintenance program could prevent costly replacement of parts and/or downtime. WARNING! To avoid personal injury, NEVER go under the lift platform or perform any maintenance on the lift until the load is removed and the scissors mechanism is securely blocked in the open position. See the "Lift Blocking Instructions" section. Monthly inspection should consist of the following: 1.
GENERAL MAINTENANCE AIR BAG REMOVAL AND REPLACEMENT WARNING! To avoid personal injury, NEVER go under the lift platform until the load is removed and the scissors mechanism is securely blocked in the open position. See the "Lift Blocking Instructions" section. 1. Engage the maintenance leg. See the "Lift Blocking Instructions”. 2. Continue to hold the “DOWN” valve after the lift has stopped traveling downward to relieve the system air pressure. 3.

TROUBLESHOOTING ANALYSIS WARNING! To avoid personal injury, NEVER go under the lift platform until the load is removed and the scissors mechanism is securely blocked in the open position. See the "Lift Blocking Instructions" section. PROBLEM Lift does not raise POSSIBLE CAUSE AND SOLUTION • The load may exceed the rating for the specific line pressure. Refer to the performance curves shown in the “Lifting Capacity vs. Air Pressure” curves in the “General Maintenance” section.
TROUBLESHOOTING ANALYSIS PROBLEM Lift raises very slowly. POSSIBLE CAUSE AND SOLUTION • The primary cause of slow actuation in airpowered systems is a lack of air volume (cubic feet per minute (CFM) to the lift. Determine the air volume of the air supply system/ compressor. For the lift to operate at reasonable speeds (2030 seconds raising time), the lift needs to have a minimum of five CFM. • Make sure all connections are tight and that no leaks are occurring in the system.
