DANGER !

Do not work under the lift without a 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.

DANGER !

Do not install the lift in a pit unless it has a bevel toe guard or other approved toe protection. A shear point can exist which can cause severe injury to the foot.

DANGER !

HIGH VOLTAGE!! Disconnect and/or lock out the electrical supply to the

power unit prior to any maintenance being performed.

DANGER !

Scissors lifts are designed individually for a specific load and application. To avoid personal injury, do not change the load or application from the original design.

DANGER !

Failure to relieve lift system pressure could result in the sudden and unexpected release of pressure during maintenance and/or repair of the lift and result in severe injury to the personnel and/or damage to the lift.

SAFETY PRACTICES

WARNING !

Do not make modifications to the lift such as extending the platform length or width, this could cause the platform to tip. Do not add unauthorized or unspecified components to the lift. Modifications to the lift can result in unsafe operating conditions which could lead to serious injury or death.

WARNING !

Do not operate this equipment without handrails and snap chains in place.

WARNING !

Under no circumstances should the down flow control valve be removed from the Deltatrol or the Contractor Power Unit to obtain faster lowering speed. A loaded lift can reach dangerous and destructive speed.

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. Failure to do so could results in personal injury or death.

WARNING !

To avoid personal injury, stand clear of scissors leg mechanism while lift is in motion.

SAFETY PRACTICES

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 !

Lift platforms traveling below floor levels my create openings, and the shape of the load and how the load is arranged on the lift may create a toe hazard as the load passes the top edge of the pit. Both situations may require guarding in accordance with Federal Regulations. Any such guarding must be installed prior to operating the lift

WARNING !

The hydraulic velocity fuse (HVF) must be properly installed! The HVF

is attached to the elbow fitting in the trust angle port (casing end) of the cylinder. Do not use a swivel fitting between the HVF and cylinder. If the HVF is installed improperly, it will not lock up in the event of a catastrophic hydraulic line break.

WARNING !

Use properly rated hoses only! Never use fittings or hoses that are not

properly rated for the intended use.

WARNING !

Never exceed the rated capacity of the lift! Overloading, or uneven

loading, could result in load instability and cause serious personal injury.

SAFETY PRACTICES

WARNING !

Any lift which has a hinged throw-over bridge damaged to the point of hanging more than 30 degrees below horizontal is in violation of the safety standards set forth in ANSI MH29.1 and MUST be taken out of service until the bridge is repaired or replaced. Failure to do so could result in severe personal injury.

WARNING !

Lifts should not be overloaded beyond the established capacity as damage and/or personal injury may result.

WARNING !

Only trained and qualified personnel should operate this equipment.

WARNING !

Whenever raising or lowering the lift, personnel should maintain a safe operating distance of at least 36” to avoid personal injury.

WARNING !

Any time the velocity fuses (HVF) have been tripped, the owner must investigate the cause of the trip and ensure any necessary corrective actions been taken, prior to resumption of normal lift operation. Failure to do so could result in personal injury.

CAUTION !

Spilled oil is very slippery, and may also present a fire hazard. Clean up all spilled oil to prevent personal injury or equipment damage.

SAFETY PRACTICES

NOTICE !

Do not continue to depress the “UP” button on the controller if the lift is not raising or if the lift has reached the fully raised position. To do so may result in permanent damage to the motor or pump.

NOTICE !

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.

NOTICE !

Do not operate the power unit on relief for more than a few seconds. When on relief, the valve will make a squealing sound.

NOTICE !

Precautions should be taken to prevent the introduction of contaminates such as dirt or other foreign material into the system through open fittings, pipes or disassembled components. Contamination will ruin the hydraulic system.

NOTICE !

Use only approved oils in the lift. See “Specifications” section.

when in the fully lowered position.

SPECIFICATIONS

LOAD CAPACITY

The load capacity rating is stamped on a metal nameplate attached to one side of the lift. This figure is a net capacity rating for a lift furnished with the standard platform. The relief valve of the pumping unit has been set to raise the weight, plus a small amount for overload. Where gravity roll-sections, special tops, etc, are installed on the lift after leaving the plant, deduct the weight of these from the load rating to obtain the net capacity.

CAUTION!

Lifts should not be overloaded beyond the established capacity as damage and/or personal injury may result and will void its warranty.

DANGER!

Do not make modifications to the lift without authorization from the manufacturer. Autoquip cannot foresee and is not responsible for injury or damage which results from the unauthorized modifications or misuse of the lift.

UNBALANCED LOADING

The stabilization provided is basically for balanced loads. If special attachments extend beyond the length and/or width dimensions of the platform, the end and/or side load capacity must be reduced (contact an Autoquip Sales representative).

PUMP PRESSURE

This lift incorporates a positive displacement pump machined to a high degree of accuracy and specially adapted to requirements of higher-pressure ranges over that of a standard pump. Therefore, standard factory models of the same manufacture cannot replace it.

The pump can operate efficiently at intermittent pressures up to 3200 PSI and continuous duty to 2500 PSI. The safety relief valve in the pump assembly or Deltatrol Valve is factory-set to stay within the parameters of the pump and lift requirements.

SPECIFICATIONS

LIFT DUTY

Autoquip standard lift designs as described in the specifications typically include intermittent duty motors and are designed to “cycle” (one complete “up” and one complete “down” lift operation) no more frequently than every two minutes – or approximately 60,000 times (cycles) per year. This is considered “normal” duty.

It is the responsibility of the user to notify Autoquip whenever a specific application is likely to demand “above normal” duty from the lift - in excess of 60,000 cycles per year. Above normal duty typically requires supplemental design features to enhance the serviceable life of the lift & to avoid loss of warranty.

LIFT BLOCKING INSTRUCTIONS

WARNING !

Only authorized personnel should perform inspection or maintenance and service procedures. Unauthorized personnel attempting these procedures do so at the risk of personal injury or death.

DANGER !

Failure to properly adhere to lift blocking procedures is to risk the sudden and uncontrolled descent of the lift during maintenance or inspection. A falling lift can cause severe injury or death.

LIFT BLOCKING PROCEDURE

This procedure describes the only factory-approved method of working under a lift. Follow these instructions EVERY time you plan to reach or crawl beneath the lift to perform service or maintenance – no matter how momentary that might be.

If the factory-provided maintenance device is damaged or missing, stop immediately and consult the factory for assistance. The manufacturer is not liable for your failure to use the approved maintenance devices and procedures that have been provided.

1. All loads must be removed from the lift prior to engaging the maintenance device. The maintenance device is designed to support an unloaded lift only. Failure to remove the load from the lift prior to blocking could cause the failure of the maintenance device and allow the lift to fall unexpectedly. This can result in personal injury or death, or permanent damage to the maintenance device and/or the lift.

2. Raise the lift to its fully raised position. If you do not, the maintenance device may not be able to be placed properly in its designed blocking position.

3. Remove the maintenance leg from its storage location at the clevis end of the lift (either under the platform or between the legs). Place one end of the maintenance leg in the leg socket on the base frame of the lift (See Figure 10).

4. Lower the lift platform until it comes down and makes contact with the maintenance leg. The maintenance leg should be centered in maintenance leg collar located underneath the platform on the clevis end. Re-check to ensure that the maintenance leg device is inside the maintenance collar and in contact with the platform deck surface. If the maintenance leg is not fully engaged the lift could fall unexpectedly, resulting in permanent damage to the devices or the lift.

LIFT BLOCKING INSTRUCTIONS

Figure 10: Maintenance Leg

LIFT BLOCKING INSTRUCTIONS

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 and the appropriate OSHA lock-out/tag-out procedure is followed. See "Lift Blocking Instructions" section.

DANGER !

If for any reason you are unable to lower the lift completely onto the maintenance device(s), stop immediately and consult the factory. Failure to properly use the factory approved maintenance device(s) could result in severe injury or death.

5. Once the maintenance device(s) is properly and securely engaged continue to press the down button for an additional 5-10 seconds to relieve all pressure in the system (it could take longer in a pneumatic system).

WARNING !

Failure to relieve the system operating pressure could result in the sudden and unexpected release of high-pressure fluids (or air) during maintenance and/or repair of the lift and result in severe injury or death.

6. Follow OSHA electrical lock-out/tag-out procedures. Disconnect and tag all electrical and/or other power sources to prevent an unplanned or unexpected actuation of the lift.

7. Once inspection or work is complete reverse steps 1-6 above, raise the lift off the maintenance device and place the maintenance device back into the designated storage position.

DANGER !

HIGH VOLTAGE!! – Disconnect and/or lock out the electrical supply to the power unit per OSHA regulations prior to any installation or maintenance being performed.

INSTALLATION INSTRUCTIONS

Before installing the 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

PIT INSTALLATION

WARNING !

DANGER !

Do not install the lift in a pit unless it has a bevel toe guard or other approved toe protection. Failure to provide approved toe protection could result in exposure to shear points and potential severe injury to personnel.

PIT DIMENSIONS: (Reference Figure 11)

1. The pit, in which the lift is installed, is the responsibility of the contractor or

owner.

2. Check the pit dimensions. The overall length and width should be 2" minimum longer and 2" minimum wider than the lift platform. Pit depth should be the lowered height plus 1/2" for shims or grout.

3. Make sure the installation area is clean before starting. Check the mounting surface of the pit floor with a level or straight edge. If the floor is not level, add shims or grout under the lift base frame along the entire perimeter of the base to achieve a level and flat base installation. A level base will ensure proper wheel tracking and smooth lift operation.

4. Check the chase (3” conduit) entrance into the pit. If the permanent electrical work is not complete, some means of temporary lines with an on-off device for the motor should be set up for testing purposes.

INSTALLATION INSTRUCTIONS

LEVELING TO GRADE:

1. The platform top should be solid and flush with the pit curb angles. The pit depth includes 1/2” added to the lowered height of the lift for leveling purposes (see Figure 11).

2. Fully lower the lift platform into the pit and check for proper height.

3. Shims and/or grout must be placed under the entire base frame assembly and the platform support members to support the platform top at grade level. DO NOT “spot” shim! Shims and/or grout must be able to support the lift base frame while loaded at full rated lifting capacity and rollover load.

STARTING UP AND LAGGING DOWN:

1. Check the routing of the temporary hydraulic lines to assure that the hose is clear of legs, bas frame, and platform when lift is in the lowered position.

2. Make positioning adjustments of the lift to align the platform with a 1” clearance around the edges of the pit.

3. Make temporary electrical connections and permanent hydraulic connections (refer to Hydraulic Piping/Hose Size chart above). The female end connection on the lift base frame is 1/2” NPT.

4. In order to run hose to the lift cylinders from a remote power unit without having to route the hose under the base frame, all 8” lowered height PLT models have been provided with the necessary fittings, (shipped-loose), to do so. Simply thread one end of the high pressure pipe nipple to the 1/2" NPT Tee located in the base frame. Thread the high-pressure hydraulic elbow fitting to the other end of the nipple (refer to Figures 13 and 14). The 1/2" NPT pipe plug may have to be relocated as shown. NOTE: Use pipe dope at all connections – DO NOT USE TEFLON TAPE.

5. Raise the lift approximately one foot using the “UP” button (Caution: Do not raise the lift to its full travel until all the air has been bled from the system. It is very difficult to lower the lift if the velocity fuses engage while the lift is fully raised). Then lower the lift back to fully collapse, holding the “DOWN” button for approximately 60 seconds. Repeat this process five to seven times to bleed any air out of the hydraulic system while confirming that the alignment of the lift in the pit is acceptable.

6. Raise the platform and install the maintenance leg (see “Lift Blocking Instructions” section).

7. Lag down the base frame in the holes provided. Lag bolts should be able to withstand 2000 lbs. minimum upward pull at each corner.

8. Replace any electrical connections with permanent.

FINAL PREPARATION:

1. Place the handrails in the platform sockets as shown in Figure 12.

2. Be sure the maintenance leg is securely in its storage position.

3. Check oil level of reservoir with the lift in the fully lowered position. Oil should be 1” to 1-1/2” below the top of the reservoir tank. (See the “Maintenance” section for oil specifications.)

4. Make sure that all applicable labels are in place in accordance to Figure 1.

WARNING!

All DANGER, WARNING, and CAUTION labels and informational decals and plates must be intact and in place on the lift. Contact an Autoquip representative if labels are missing or damaged.

CLEAN UP:

1. Clean up any spilled oil and debris from the area. A clean installation makes a good impression and creates a much safer environment!

2. Touch-up paint is available by request from Autoquip for repair of damaged paint surfaces.
