    *When mounting a “T-Series” lift on a pad it is necessary to supply a cutout in the concrete to allow passage of the hose under the 
    base frame. T-Series lifts have no clearance between the platform and ground, any hose run through or over the base frame will be 
    damaged when the platform is lowered.

    SECTION 5:  OPERATING INSTRUCTIONS 
      
    Hydraulic scissors lifts have an excellent safety record overall, but as with all moving 
    equipment they can be dangerous.  Operators must use common sense and take 
    responsibility for the safety of everyone near the lift.  They must use the devices 
    provided and be careful not to surprise anyone in the area with the movement of the lift. 
     
    The most common accidents that occur are people walking off the end of the lift and 
    people tripping over the hinged bridge or knocking the bridge over onto someone’s foot.  
    These are prevented by simply using guardrails and safety chains, and by being aware 
    of the bridge position and size. Be alert! 
     
    Pre-operational checks:  
    1.  Check all electrical wiring and connections to be sure that they are completed 
    properly and are operational. 
     
    2.  Check for the proper operating condition of all safety devices such as guardrails, 
    safety chains, and optional equipment such as electric toe guards, warning bells, or 
    automatic chocks. 
     
    3.  Check for obstructions or debris that may interfere with the safe operation of the lift. 
    Caution!  Obstructions and debris in the pit can cause the lift to remain partially raised 
    above the surrounding surface causing a trip hazard. 
     
    4.  Be sure that all personnel in the area are a safe distance away from the lift and 
    aware that you are about to move it. 
     
    5.  Know the capacity of the lift to be sure not to overload it.  
    Test operate the equipment: 
     
    1.  Station yourself so that you always see the equipment and surrounding area when it 
    is in operation.  Never operate the equipment in the blind. 
     
    2.  Raise the equipment and note that the pushbutton is a constant pressure, “dead-
    man” type.  When you release the up or down button, the unit should stop moving 
    immediately and maintain its elevation.  If it does not, notify your maintenance 
    personnel immediately. 
     
     
    3.  Cycle the equipment several times to be sure that it is operating smoothly with no 
    jerking or sudden movement.  On initial start up there may be some air in the lines or 
    the cylinders may be dry due to storage so it may take several cycles to smooth out 
    the operation.  If the operation is not smooth after several cycles, contact your 
    maintenance personnel.  If there is any evidence of binding or scraping in the 
    operation you should immediately stop using the lift.
     
     
    4.   Check all safety devices for proper operation. 
     
    5.   If you elect to test load the equipment be sure that you do not exceed the capacities 
    shown on the nameplate.  Overloading may cause structural stresses that may not 
    show up for some time, but will diminish the life and capacity of the unit.  If you have 
    any questions about testing the unit, call the engineering department at the factory at 
    1-800-843-3625.

    COMPATIBLE LOADING EQUIPMENT GUIDE: 
     
    Each Advance lift is designed with a weight capacity and platform design for specific 
    types of loading equipment.  Using the wrong type of loading equipment on a given 
    series of lifts will invite unintentional overloading.  For safe operation, follow these 
    guidelines and be careful to never exceed the nameplate. 
     
     
     
     
     
     
     
     
     
     
     
              
     
              
                                 
    Calculate the weight of the heaviest types of loads you expect to handle to be sure that 
    they are within the rated capacity.  Beware of surprisingly heavy materials such as 
    liquids, grains, powder, and paper; all of which can weigh much more than you suspect 
    because of their density.  
     
    A little effort to determine the true weight of your heaviest loads before you start to use 
    your equipment can save damage to your equipment and possible injury to your 
    personnel.  If you discover that some loads will exceed the capacity of the unit, make 
    arrangements to have the loads split.  All operating personnel should be warned about 
    heavy loads, warning signs should be placed in the dock lift area as a reminder. 
     
    Daily operation: 
     
    1.  All personnel should be required to read the entire operating instruction section of 
    this manual prior to operating the lift. 
     
    2.  Operators must know the capacity of the unit and be aware of any loads that may 
    exceed capacity. 
     
    3.  Operators must be alert to all personnel in the vicinity of the lift and avoid any 
    surprises to these personnel in regard to movement of or the position of the lift at 
    any time.  Never operate the unit if you can not see it and the personnel around it. 
     
    4.  On the first use of the lift each day, each operator should check to see that the lift is 
    operating properly and smoothly. All safety devices should be in place and operating 
    properly and the hinged bridge should be swung through its full arc of movement. 
    The bridge stops should prevent the bridge from drooping more than 45 degrees 
    below the horizontal in the forward position and the bridge should swing back 20 
    degrees beyond vertical toward the platform in the upright position.  Any problems 
    should be immediately reported to the maintenance personnel.

    Daily Operation (Continued) 
     
    5.  If the unit has a traveling electrical cord, the operator must insure that it is kept away 
    from the lift as it rises and lowers. 
     
    6.  When raising or lowering the lift, the load should be centered on the platform (that is, 
    the load should be evenly distributed and its center of gravity should be at the center 
    of the platform). 
     
    7.  If a unit is equipped with both a hinged bridge and a hinged ramp, be sure that the 
    operators know the difference and never use the ramp for load transfer in the raised 
    position.  The ramps are usually much longer than the bridges which means they 
    can work as a long lever creating severe eccentric loads and they are often 
    positioned on the weakest side of the lift for load movement in the fully lowered 
    position only. Use ramps in the fully lowered position only! 
     
    8.  Do not allow bridges or ramps to “free fall” from near vertical positions to the position 
    against their hinge stops.  This type of abuse will definitely cause damage to the 
    stops, hinges, and platform edges, eventually rendering the unit unsafe.  Lower 
    ramps by hand and lower bridges to the down stop position with the restraining 
    chains. 
     
    Efficient lift usage:  
    The following procedures will help you maximize the efficient use of your lift in your 
    loading and unloading operations. 
     
    1.  First it should be noted that there is a long restraining chain on each lift that is 
    designed to run from the hinged bridge to the guardrail post farthest away from the 
    bridge.  The purpose of this chain is to allow an operator to pull the hinged bridge 
    back from anywhere on the platform with minimal movement, once the bridge is 
    raised to the near vertical position by the truck bed as the lift is lowered. 
     
    2.  This means that the hinged bridge only has to be manually lifted once in a loading or 
    unloading sequence.  It should be raised to the vertical standing position before the 
    lift is raised to truck height.  Once the top of the bridge is just above the truck bed 
    height, the bridge can be pushed against the truck and allowed to cam into truck.  
    Then when you lower the unit, the bridge is allowed to cam up on the truck bed to 
    the near vertical position and then pulled back to a safe resting position with the 
    chain.  There is a second snap on the chain that allows you to lock the bridge in the 
    raised position whenever the load or guardrails prevents the bridge from swinging 
    back at least 20º beyond vertical. (See illustration at end of section.) 
     
    3.  If your unit is equipped with an approach ramp, do not raise the ramp on each cycle.  
    In fact, the ramp is to be raised only when the lift is being moved to a new location.  
    Many of the ramps are designed with built in wheel chocks which help prevent a 
    wheeled vehicle from rolling off the platform and only work properly when the ramp 
    is lowered.

    Placing Bridge in Truck 
    With bridge folded back toward platform raise the dock lift 
    until the top the bridge is just above the opening of the 
    truck, push the bridge against the truck with your foot while 
    controlling the fall with the safety chains. As the dock lift is 
    raised, the bridge will cam over onto the truck bed and lay 
    flat for loading and unloading.  
     
     
    Removing Bridge from Truck and Securing Begin to lower the dock lift until the bridge starts to cam up 
    over the end of the truck bed. With foot, chain, or hand, flip 
    bridge back toward platform. Once bridge is folded back 
    toward platform attach safety hook (A) to secure the bridge 
    in place and continue lowering the unit. 
     
    Bridge starts to cam up over 
    end of truck bed as the dock 
    lift raises or lowers. 
    DANGER! Do not remove bridge stops or allow bridge to hang vertically.  
    						
    							 
     
    SECTION 6:  MAINTENANCE INSTRUCTIONS 
     
     
     
    The routine maintenance of this equipment is minor and consists of periodic checks. 
     
    Weekly: Once a week, or after repetitive operation, the lift should be raised to its full 
    height.  This will get rid of cylinder oil seepage build-up and lubricate the upper cylinder 
    barrel. 
     
    Monthly: Check that the hydraulic fluid level in the reservoir is 1” to 2” from the top of 
    the tank, depending on model, with the unit fully lowered. It is strongly urged that a 
    maintenance log be maintained with the dates of monthly inspections, the name of the 
    inspector and results of the inspection. 
     
    CAUTION: 
     
    Be sure the maintenance device is properly engaged before performing maintenance 
    checks 2 through 6 or reaching beneath a raised lift.  (Read all of section 6 for proper 
    maintenance safety leg procedures). 
     
    1. Clean all debris from the pit or the vicinity of floor mounted units in order to avoid 
    interference with the lift mechanism or rollers. 
     
    2. Check for presence and proper seating of all snap rings and clips on all axles, 
    cylinders, and rollers. 
     
    3. Check rollers, pins and bushings for any signs of wear such as flat spots, missing 
    fasteners, or dislodged bearing material. 
     
    4. Check the hydraulic fittings for cracks or leaks and clean up any seepage on or 
    beneath the cylinders. 
     
    5. Check hoses and electrical lines for abrasions or other abuse and check for snug 
    connections. 
     
    6. Operate the unit and check for any abnormal noise or vibrations. 
     
    7. Check all safety devices on the unit such as guardrails, safety chains, etc. including 
    any options such as electric toe guards or chocks, for proper operation. 
     
    8. Check the hinged bridge to insure that its stops are not damaged, allowing it to droop 
    more than 45 degrees below horizontal, check the hinge spools for cracks and or 
    broken welds, be sure the bridge leans back over the platform at least 20 degrees 
    beyond vertical. 
     
    Seasonal or semiannual maintenance: 
     
    Change hydraulic fluid for ambient temperature changes if appropriate. Check the fluid 
    reservoir to see if there is any evidence of accumulated condensation creating water 
    contamination. The fluid will appear “milky” and light pink in color. Water accumulation 
    will damage the hydraulic pump. 
     
     
     
    P 6-1 
    						
    							 
     
     
    SECTION 6: (CONTINUED) 
     
    Maintenance Cautions: 
     
    1.  Always remember that this is a piece of machinery with large moving parts that can 
    seriously hurt you. 
     
    2.  Read this manual in its entirety before attempting service work. 
     
    3.  Always use the maintenance device if you are going to work on the unit in the 
    elevated position or reach under the platform.  (See the illustrations at the end of this 
    section for proper positioning and engagement of the maintenance supports.) 
     
    4.  It may be necessary to bypass travel limit switches in order to properly position the 
    maintenance support.  
     
    5.  When using the maintenance support observe the following rules: 
     
    A.  There shall be no load on the platform 
    B.  The maintenance support shall be properly engaged. 
    C.  Hold the down button an extra 10 seconds when lowering onto the maintenance 
    support to be sure that all the weight of the lift is on the support. 
    D.  Use shoring of blocking as a backup to the maintenance support. 
    E.  Disconnect and tag the electricity to the unit to prevent accidental movement of 
    the lift by other personnel. 
    F.  Spend as little time as possible under the lift. 
     
    6.  Use only replacement parts recommended by the manufacturer. 
     
    7.  Do not let the equipment stay in disrepair; fix little problems while they are little 
    problems or some of them may get severe very quickly. 
     
    8.  Inspect the equipment on a regular schedule, preferably monthly. 
     
    9.  Never work on the hydraulics or electrical systems unless the unit is fully lowered or 
    properly sitting on a maintenance support. 
     
    10. Never apply a load to the equipment unless the base is continuously supported and 
    non-portable units are securely lagged to the ground. 
     
    11.  Never expect to hold leg assemblies open by simply lifting one end of a platform. 
     
    A.  The roller end of most lifts are not gibbed or captured in any way, so lifting on the 
    roller end simply tilts the platform.  
    B.  Even if you raise the clevis end of the platform, if the base frame is not firmly 
    lagged to the ground or held down by some other means, the legs will come up 
    with the platform in a spongy and unpredictable manner and could cause serious 
    injury. 
    C.  The only safe way to hold a lift’s legs open other than the factory designed 
    maintenance support is to block between the clevis end of the platform and the 
    base frame.

    Section 6: (Continued) 
    Recommended Lift Blocking Procedures 
     
    WARNING! 
     
    Only authorized personnel should perform inspection or maintenance and 
    service procedures.  Unauthorized personnel attempting these procedures do 
    so at the risk of severe 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. 
     
    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 device(s) and procedures that have been provided. 
     
    1.  Any load must be removed from the lift prior to engaging the maintenance device(s).  
    These devices are 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(s) and allow the lift to fall unexpectedly.  This can result in personal injury or 
    death, or permanent damage to the maintenance device(s) and/or the lift. 
     
    2.  Raise the lift to its fully raised position.  If you do not, the maintenance device(s) may 
    not be able to be placed properly in its/their designed blocking position. 
     
    3.  Remove the maintenance device(s) from its/their storage location and place it/them 
    into the engaged position as shown in Figures 1-5. Read and understand the 
    specific instructions for your equipment before proceeding. 
     
    4.  Lower the lift until it makes complete contact with the maintenance device(s).  Re-
    check to ensure that all provided devices are fully and securely engaged.  If the 
    device(s) is/are not fully engaged the lift could fall unexpectedly, resulting in 
    permanent damage to the device(s) or the lift.

    Recommended Lift Blocking Procedures (continued)
     
     
     
    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/are properly and securely engaged, continue to 
    press the down button, valve or switch for an additional 5-10 seconds to relieve all 
    pressure in the operating system. 
     
     
     
    WARNING! 
     
    Failure to relieve operating system 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 the performance of the steps above to 
    raise the lift off the maintenance device(s) and place the device(s) back into its/their 
    designated storage position(s). 
     
     
    DANGER! 
     
    HIGH VOLTAGE! – Disconnect and/or lock out the electrical supply to the power 
    unit prior to any installation or maintenance being performed.

    CAUTION! Read the entire lift blocking procedure and all warnings 
    before attempting to use the 
    maintenance bar. ALL MODELS  
    Never use the maintenance device when the 
    platform has a load. Remove the load first, 
    then brace for service or maintenance. Check 
    that the maintenance bar is well seated and 
    remains so during heavy wrenching or 
    maintenance operations. FOR SERIES 2000K  Place the maintenance bar near the center of 
    the torque tube and against the base frame; 
    be certain the bar is captured on the base 
    frame angle, and then lower the equipment 
    until it is totally supported by the bar. (Fig. 1) FOR SERIES 2000  Place the maintenance bar near the center of 
    the torque tubes and then lower the
