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 the lift has not been damaged in transit. Any damage found must be noted on the delivery receipt.
DANGERS, WARNINGS & CAUTIONS 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.
DANGERS, WARNINGS & CAUTIONS Read and understand this manual and all labels prior to operating or servicing the 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.
DANGERS, WARNINGS & CAUTIONS DANGER! Extending the platform length or width beyond the factory limit could cause the unit to tip, which could result in personal injury or death. WARNING! Do not operate this equipment without handrails and snap chains in place. WARNING! Under no circumstances should the speed control orifice be removed from the Deltatrol to obtain faster lowering speed.
DANGERS, WARNINGS & CAUTIONS 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.

LIFT BLOCKING INSTRUCTIONS 1. Remove all load from the platform. Never block the lift when loaded, only when empty. 2. Raise the lift platform fully by depressing the “UP” button. 3. The maintenance leg is stored on the clevis end of the lift. Place the end of the maintenance leg in the socket on the base frame of the lift. 4. Begin lowering the platform by activating the “DOWN” valve until the scissors mechanism is resting on the maintenance leg.
LIFT BLOCKING INSTRUCTIONS 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.
INSTALLATION INSTRUCTIONS 1. The surface area where the lift will be set must be flat and level and be of sound concrete of sufficient thickness to support the lift while loaded at full capacity. 2. For beveled toe guard models, the surface area must have a recess to allow hydraulic lines to pass under the ends of the base frame. Hydraulic lines must be protected or placed in a way that they are free from possible damage. 3. The base of the lift must be lagged down in the holes provided.
INSTALLATION INSTRUCTIONS PROCEDURE FOR A LIFT ORDERED WITH AN ACCORDION SKIRT 1. Position the platform in the raised position. Install the maintenance locks (see “Lift Blocking Instructions” section). Position the accordion with the weight rod pocket at the bottom and the mounting collar at the top. The breathable material when provided must be positioned at the top of the skirt with the mounting collar. 2. Slip the skirt over the end of the platform.

OPERATING INSTRUCTIONS Familiarize yourself with this operator’s manual before operating the equipment!!! 1. Scissors lifts have maximum lifting capacity ratings (see “Specifications” section). The safety relief valve has been factory set to open at a pressure slightly above the rated load capacity and allows the oil to bypass into the reservoir to prevent damage to the lift and its hydraulic power unit.
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 "Lift Blocking Instructions" section. MONTHLY INSPECTION: 1.

GENERAL MAINTENANCE 1. Change oil once a year or when it materially darkens or feels gritty. Also, check oil for the presence of water (oil will turn milky in color.) 2. NEVER TRY TO DISASSEMBLE OR REPAIR A PUMP IN THE FIELD. These pumps are high-precision devices requiring extreme precision in fit-up. When one is damaged, there is seldom anything that can be repaired in the field. It is also more economical to replace a pump than to refit old parts with new parts. 3.
GENERAL MAINTENANCE CYLINDER REMOVAL AND REPACKING (see figure 12) 1. Raise the lift to its full height and block securely. See “Lift Blocking Instructions”. 2. Loosen and remove the cylinder hose at the hose union in the tee connection between the two cylinders. Place the open end of the hose in a container to receive oil spillage. 3. Remove the pin retaining screw in the cylinder clevis or pin retaining rings, and carefully tap out the clevis pin to avoid damaging the clevis pin bushings. 4.
GENERAL MAINTENANCE 14. Install the rod into the tube using care not to damage any seals or packing 15. Align the retainer hole in the bearing assembly groove with the slot in the tube. 16. Insert the retainer hook end in the hole/slot and using a face spanner wrench, turn the bearing assembly clockwise until the retainer is completely inserted in the groove/slot in the tube. 17. Check the clevis pin bushings in the cylinder rod for wear and replace as necessary. 18.

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.

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 POSSIBLE CAUSE AND SOLUTION Lift does not raise. • The motor voltage/wiring may be incorrect. • The hydraulic line or hose may be leaking. • Oil in the reservoir may be low. Add oil as necessary (See the “Routine Maintenance” section.) • The load may exceed the rating.
TROUBLESHOOTING ANALYSIS PROBLEM Lift will not lower. POSSIBLE CAUSE AND SOLUTION The down solenoid may be malfunctioning. The maintenance leg could be installed. The structural members may be in a bind. The tubing or hose is obstructed or broken. Check for obstruction in the line. • The return filter may be clogged. • 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.
TROUBLESHOOTING ANALYSIS PROBLEM Lift raises slowly. POSSIBLE CAUSE AND SOLUTION • The structural members of the lift may be binding. • The tubing or hose is obstructed or broken. Where pipe is used, check for obstruction in the line. • The hydraulic line or hose may be leaking. • The oil viscosity is not suited for the environmental conditions. Refer to “Routine Maintenance” section for oil recommendations. • Check the oil level in the reservoir. • The motor voltage/wiring may be incorrect.
TROUBLESHOOTING ANALYSIS PROBLEM Lift will not remain in raised position. POSSIBLE CAUSE AND SOLUTION • The cylinder packing may be leaking. • The pump or Deltatrol regulator is not seating. • The pump or Deltatrol check valve is not seating. • The hydraulic tubing, hose, or fitting is leaking oil. • The return filter may be clogged.
