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.
RESPONSIBILTY OF OWNERS/USERS DEFLECTION It is the responsibility of the user/purchaser to advise the manufacturer where deflection may be critical to the application. INSPECTION & MAINTENANCE The lift shall be inspected & maintained in proper working order in accordance with Autoquip’s operating/maintenance (O&M) manual and with other applicable safe operating practices.
SAFETY SIGNAL WORDS SAFETY ALERTS (Required Reading!) The following SAFETY ALERTS are intended to create awareness of owners, operators, and maintenance personnel of the potential safety hazards and the steps that must be taken to avoid accidents. These same alerts are inserted throughout this manual to identify specific hazards that may endanger uninformed personnel. Identification of every conceivable hazardous situation is impossible.
SAFETY PRACTICES Read and understand this manual and all labels prior to operating or servicing the scissors 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 "Lift Blocking Instructions" section.
SAFETY PRACTICES 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 Autoquip for replacements. WARNING! Do not attempt to remove the velocity fuse until the maintenance block securely supports the lift and all hydraulic pressure has been removed from the lifting cylinders and hydraulic hoses.
SAFETY PRACTICES CAUTION! Never run the pump for more than a couple of seconds without pumping oil. This applies to low oil conditions, improper motor rotation, running the pump against the relief pressure after the lift is fully raised against the physical stops, running overloaded beyond capacity, or running at reduced speed because of pinched or obstructed hydraulic lines. CAUTION! Do not operate the power unit on relief for more than a few seconds. When on relief, the valve will make a squealing sound.

INSTALLATION INSTRUCTIONS Figure 10 Skirt Installation 21
OPERATING INSTRUCTIONS 1. Operate this lift only on a firm, flat & level surface. 2. Place the lift in loading position and lock the floor lock when not being transported. 3. Scissors lifts have maximum lifting capacity ratings (See the “Specifications” section). The safety relief valve has been factory set to open at a point slightly above the rated load and allows the oil to bypass into the reservoir.
ROUTINE MAINTENANCE WARNING! Before installing lift, read & follow the recommended safety practices in the Safety Practices section. Failure to follow these safety practices could result in death or serious injury. Normally scissors lifts will require very little maintenance. However, a routine maintenance program could prevent costly replacement of parts and/or downtime.

GENERAL MAINTENANCE WARNING! Before installing lift, read & follow the recommended safety practices in the Safety Practices section. Failure to follow these safety practices could result in death or serious injury. CYLINDER REMOVAL AND REPACKING 1. Raise the lift to its full height and block securely. See “Lift Blocking Instructions”. 2. Cut off the electricity to the power unit (lock out-tag out). 3. Disconnect the cylinder hose at the power unit end and insert it into the oil-fill hole of reservoir.
GENERAL MAINTENANCE 14. Check the piston head nut for tightness and torque to 600-650 ft. lbs on 3 ½” bore cylinders or 850-950 ft. lbs. on 4” bore cylinders. The upper clevis and pin may be used to prevent the rotation of the rod while tightening. 15. Liberally lubricate the piston and seal with CLEAN grease or oil. 16. Reinsert the piston into the barrel, taking care not to pinch or nick the new seal. 17. Slip the bearing assembly into place and align the retainer hole with the slot in the barrel.
GENERAL MAINTENANCE VELOCITY FUSE REPLACEMENT DANGER! Do not attempt to remove the velocity fuse until the lift is securely supported with the maintenance locking devices and all hydraulic pressure has been removed from the lifting cylinders and hydraulic hoses. Failure to follow these instructions could result in personal injury or death! Never attempt to take a velocity fuse apart and repair it. These are precision devices that are factory assembled under exacting conditions.

GENERAL MAINTENANCE WIRING AUTOQUIP "SUPER TORQUE' MOTORS Because Autoquip "Super-Torque" motors actually deliver substantially more horsepower than their nameplate rating, they must always be wired for heavier currentdraw than standard motors of the same nameplate rating. However, because of the "Super-Torque" motor’s starting efficiency and superior running characteristics, circuit components do not have to be as large as for standard motors of equal delivered horsepower.

TROUBLESHOOTING ANALYSIS DANGER! 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 "Lift Blocking Instructions" section. PROBLEM Lift raises, then lowers back slowly. POSSIBLE CAUSE AND SOLUTION The "Down" solenoid may not be seating. Remove the solenoid coil and check again.
TROUBLESHOOTING ANALYSIS PROBLEM POSSIBLE CAUSE AND SOLUTION Lift does not raise. The battery may not be charged. Charge battery. Check for a line or hose leak. Check for oil shortage in the reservoir. Add oil as necessary (See Oil Requirements in the “Routine Maintenance” section.) The load may exceed the rating. (See the “Specifications” section.) Remove the excess load. The suction screen may be clogged, starving the pump. Remove and clean the screen. Drain and replace the oil.
TROUBLESHOOTING ANALYSIS PROBLEM Lift won’t lower. POSSIBLE CAUSE AND SOLUTION The solenoid coil may be incorrectly wired, burned out, not rated for the voltage, or the line voltage may be excessively low. Check voltage near the coil. The velocity fuse may be locked. Do not attempt to remove the velocity fuse. The following steps should be followed: 1. Remove the load from the lift. Inspect all fittings, hoses, and other hydraulic components for leads or damage. 2.
TROUBLESHOOTING ANALYSIS PROBLEM Lift seems bouncy during operation. Motor labors or heats excessively. POSSIBLE CAUSE AND SOLUTION Battery connections connections. Lower the lift to collapsed position and continue to hold “DOWN” button an additional 10-30 seconds to bleed air from the cylinder.
