the unit.
6. Instruct user(s) in the proper operation of the lift, safety precautions, and equipment
capacity. Supply maintenance personnel with this service manual.
Pit mounted units:
1. Check all pit dimensions for accuracy.
2. Attach a temporary air line through the pit conduit to the lift.
3. Using slings, encircle the entire lift, not just the platform and lower the lift into the pit,
centering it for 1” minimum clearance on all sides to the pit wall.
4. Raise the lift with the control valve and remove the slings. Run the unit up and down
several times to insure proper clearances on pit walls.
5. Fully raise the unit and insert maintenance bars, lower unit onto the bars and
discharge air until air pressure is relieved from the system. CAUTION! See page (P
6-3) for complete instructions for proper maintenance bar instruction.
6. Level and center the lift by shimming and grouting the entire baseframe, not just the
corners. Lag the unit in place using ½” x 5”, “Rawl-Studs” or wedge anchors in the
holes provided.
Caution! Continuous baseframe support is essential for proper installation
7. Follow the instructions outlined in paragraphs 5 and 6 under “Floor mounted
installation”. To complete the installation.
P 4-1
SECTION 5. OPERATING INSTRUCTIONS
Pneumatic 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 safety devices
provided and be careful not to surprise anyone in the area with the movement of the lift.
Pre-operational checks:
1. Check all air connections to be sure that they are completed properly and are
operational.
2. The air supply shall be regulated at 70 PSI; it shall also be dry.
3. Check for obstructions or debris that may interfere with the safe operations of the lift.
4. Be sure that all personnel in the area are a safe distance away from the lift and
aware that you are about to operate it.
5. If there are any optional safety devices such as limit switches, check them for proper
operation.
Test operate the equipment:
1. Station yourself so that you will always see the equipment when it is in operation.
Never operate the equipment blind!
2. Raise the equipment and note that the control is a constant pressure, “dead-man”
type. The control knob shall spring to the neutral position when pressure is released,
if not, the control shall be rebuilt or replaced.
3. Cycle the equipment several times to be sure that it is operating smoothly with no
jerking or sudden movement. If the operation is not smooth after several cycles,
contact your maintenance personnel to have the air plumbing checked. Any
evidence of binding or scraping in the operation shall cause you to immediately stop
using the lift and contact the factory.
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 our customer service department at 1-800843-3625.
Daily operation:
1. All personnel shall 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 the capacity.
3. WARNING! Operators must be alert to personnel in the vicinity of the lift. Avoid any
surprises to these personnel in regard to movement of or the position of the lift.
Never operate unit if you cannot see it and the personnel around it.
P 5-1
SECTION 5. (CONTINUED) OPERATING INSTRUCTIONS
Daily operation (continued):
4. On the first use of the lift each day, the operator shall check to see that the lift is
functioning properly and smoothly. All safety devices shall be in place and operating
correctly.
5. If the unit has a traveling air line, the operator must insure that it is kept away from
the lift as it raises and lowers.
6. The center of the load shall be centered on the platform before raising or lowering
the lift as this will help insure even wear on all moving parts
General Compressed Air Information Notes:
1. PSI and SCFM will affect the speed and capacity of an air spring actuated lift. An
increase in PSI will increase the capacity of the lift, as a drop in PSI will reduce the
lift capacity.
2. SCFM and load weight will primarily affect the speed in which the table rises. While
load weight will have the greatest effect on the lowering speed.
3. Advance Lifts air spring lifts are designed to operate at 70 PSI.
SECTION 6. MAINTENANCE INSTRUCTIONS
1. Always remember that machinery with large moving parts can seriously injure you.
2. Read and understand this manual before attempting any service work.
3. WARNING! Always use the safety bars or safety leg when working on the unit in the
elevated position or reaching under the platform. (See photos 6-1 and 6-2, at the
end of this section for proper positioning and engagement of the safety bars).
4. When using the safety bars, adhere to the following rules:
A. The unit must be unloaded.
B. Be sure the safety bars are properly engaged.
C. Hold the down pedal or pushbutton an extra 10 seconds when lowering onto the
safety bars to be sure that all the weight of the lift is on the bars.
D. Disconnect and tag the electricity to the unit to prevent accidental movement of
the lift by other personnel.
E. Spend as little time as possible under the lift.
5. Only use replacement parts recommended by the manufacturer.
6. Do not let the equipment stay in disrepair, fix small problems before they become big
problems. A unit in disrepair can become a severe hazard if left unattended.
7. Inspect the equipment on a regular schedule, preferably monthly.
P 6-1
SECTION 6. (CONTINUED) MAINTENANCE INSTRUCTIONS
8. Never work on the pneumatic systems unless the unit is fully lowered or properly
sitting on the safety support or wheel block.
9. Never apply a load to the equipment until the baseframe is continuously supported.
10. WARNING! Never expect to hold the leg assemblies open by simply lifting one end
of a platform.
A. The roller end of most lifts is not “gibbed” or captured in any way, so lifting on the
roller end will simply tilt 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 an unpredictable manner and could cause personal injury.
C. The only safe way to hold a lift’s legs open other than the factory designed safety
support, is to block between the clevis end of the platform and the baseframe.
Routine Maintenance: (All lifts)
Weekly: Once a week or after repetitive operation, the unit shall be raise to its full
height. The air spring and supply hose shall be examined for signs of wear.
Monthly:
WARNING! Be sure a maintenance safety leg or safety bars are properly engaged
before performing maintenance checks 2 through 6 or reaching beneath a raised lift.
(See instructions 3, 4 and 10 above).
1. Clean all debris from the vicinity of floor and pit 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 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 pneumatic fittings for cracks or leaks.
5. Check hoses 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 the condition of the pleated bellows or
smooth operation of a limit switch.
P 6-2
SECTION 6. (CONTINUED) MAINTENANCE INSTRUCTIONS
SAFETY MAINTENANCE BAR INSTRUCTIONS
WARNING! Always use the safety bars for any service or maintenance. Never go or
reach under the lift unless both safety bars are securely in place and the power to the
unit has been disconnected to prevent others from operating the lift. Never use the
safety bars with a load on the platform.
CAUTION! Never use the lift unless the safety bars are properly stored or damage may
occur to the equipment.
1. Remove the safety bars from their storage positions by loosening the wing bolts.
2. Raise the lift to full travel, and place a safety bar in front of each roller wheel on the
scissors leg. Make sure the safety bar angle captures the baseframe angle (see
photos numbered 6-1 and 6-2). Caution! Do not tighten the wing bolt.
3. Once both safety bars are in place, slowly lower the lift until the roller wheel is
engaged with the safety bars and the safety bars rest against the end of the
baseframe. Visually inspect both safety bars to insure they are secure.
4. To disengage the safety bars raise the lift to move the roller wheels off the safety
bars and make sure lift operates correctly. If assistance is required in removal of the
safety bar, lightly tap with a hammer to brake it loose. Store the safety bars in their
original position and tighten the wing bolt.
Store the safety maintenance bar in position shown below. Failure to do so would allow
the moving leg to impact the maintenance bar when the list is fully lowered. (See the
photographs, 6-1 and 6-2).

SECTION 10. TROUBLESHOOTING HINTS
Warning! Only qualified service personnel shall be allowed to perform service work on
pneumatic lifts. The service person shall be familiar with this manual before attempting
any service on the lift.
Warning! No work shall be performed beneath a raised lift platform unless the safety
leg or maintenance blocks are installed in accordance with Section 6 of this manual
UNIT WILL NOT LIFT
1. Reduce load to rated capacity.
2. A small amount of debris may be stuck in the control valve. Disassemble the air
valve and clean.
3. Confirm correct air pressure supply; refer to Section 5 for correct operating pressure.
4. Check air lines for kinks or damage.
5. Inspect lift for physical damages that may be causing binding and restricting travel.
UNIT WILL NOT LOWER
Danger! If a lift fails to lower when the valve is actuated yet air is being relieved from the
valve great caution must be exercised. Air spring tables are slower to react than
hydraulic lifts and mechanical binding or debris may be restricting the lifts travel. If the
binding or debris is removed before the table is raised, the table may drop suddenly.
1. An object or debris may be blocking the rollers from moving. Caution! Do not attempt
to remove an obstruction without first raising the unit to full height and inserting the
maintenance blocks, See page 6-3 for instructions.
2. The air control valve may be malfunctioning, raise the unit and install the
maintenance blocks, then disassemble and clean the valve components.
