THIS MANUAL CONTAINS IMPORTANT INFORMATION CONCERNING THE INSTALLATION AND
OPERATION OF VEHICLE LIFTS.
WE OFFER TWO SUGGESTIONS:
• READ ALL MANUALS THOROUGHLY BEFORE INSTALLATION.
• KEEP ALL MANUALS FOR FUTURE REFERENCE.
1 Do not exceed the rated load capacity of the lift.
2 Do not continue to push the control lever after lift is fully raised, even though safety valve will prevent
over-inflation of air bag.
3 Use lift only on level surfaces.
4 Keep clear of lift while it is in motion.
5 Do not use air supply exceeding 120 PSI.
6 Do not leave a vehicle raised on the lift overnight.
7 Do not operate lift with defective Control assembly.
8 Never for any reason put arm or any other body part inside lift.
1 Herkules will not be held responsible for any personal injury and/or property damage due to
owner/operator failure to follow the warnings and cautions listed in this manual.
2 Read and understand all warnings, cautions, instructions and manuals before operating this equipment.
3 It is the owner/operators responsibility to maintain the legibility of all warning and instruction labels.
4 DO NOT alter or modify any part of this equipment.
5 DO NOT attempt to bypass the safety lock system.
6 DO NOT tamper with pressure relief valve system inside the lift.
7 DO NOT operate lift while person(s) are in the vehicle
8 ALWAYS check equipment regularly for proper operation and repair or replace worn or damaged parts
immediately.
9 ALWAYS remove damaged lifts from service until repairs are made to the unit. Use only manufacturer's
approved parts and accessories.

Locate lift on a level surface in a position most convenient for the loading and unloading of vehicles.
Obtain hose clamps
ID Part # Description Qty.
1 1000166 CLAMP HOSE WIDE BAND #8 SS/Z 1
2 720-122 CLAMP HOSE # 4 SS/Z 1
Using the hose clamp (1000166), clamp the 3/8" ID air line from the lift to 3/8" hose barb on the hand control
assembly (see fig.1).
Using hose clamp (720-122), clamp the 1/4" ID air line from the lift to hose barb (1004805) on the hand
control assembly (see fig.1).
NOTE: Check these connections periodically to prevent leakage.
Obtain 1/4 NPT connector compatible with the quick disconnect on your shop air line.
NOTE: Connector not supplied with lift.
Install 1/4 NPT connector into open port (Port 1) on hand control valve (see fig.2).
Connect your shop air line to connector and test for proper operation.
NOTE: Must use clean, dry air only. Herkules recommends using a filter/regulator (see Optional Accessories).

I. Lift Cycle Rating:
This lift is rated for 1 - 5 cycles per day maximum. For high cycle usage warranty does not apply.
II. Duty Cycle:
This lift is rated for approximately 7,000 - 10,000 cycles between repairs (MTBF). This lift is not rated for high duty cycles.
Items that will need repair may include: 1) air bag, 2) safety ratchet, 3) scissors, 4) pivots, and 5) valves.
For heavy duty scissor lift systems that requires little maintenance Herkules recommends our Herkules Ball Screw or Belt
Drive Scissor Lift Systems. These lift systems are designed and manufactured for high duty cycles and long life.
Herkules recommends our electric Ball Screw or Belt Drive lift system for high cycle applications.
Check the weight of the vehicle to be sure that it does not exceed the rated load capacity of the lift: 5,000 lbs.
Drive the vehicle over the first set of ramps and onto the second set of ramps so that all four tires are on the lift, and position the
vehicle so that the vehicle is centered by weight over the center of the lift. Once the vehicle is in the desired position,
set the parking brake of the vehicle.
To raise the lift, move the lever of the hand controller assembly into the UP position. Hold the lever in the UP position
until vehicle has reached the desired working height, then release. The mechanical safety arms will automatically
fall into position as the lift rises.
Do not continue to push the control lever after lift is fully raised, even though safety valve will prevent
over-inflation of air bag.
NOTE: Check the stability of the vehicle during the lifting process, and when vehicle is at desired working height.
If vehicle is unstable, immediately stop the lifting process, slowly lower the lift and reposition vehicle.
To lower the lift, move the lever of the hand controller assembly into the DOWN position. Hold the lever in the DOWN
position until the lift is completely lowered and the wheel platforms are resting on the ground. The mechanical safety arms
will swing up during descent.
NOTE: Check the stability of the vehicle during the lowering process. If vehicle is unstable, immediately stop and
diagnose the issue before continuing to lower the lift.

Once the lift is completely lowered, drive the vehicle off of the lift.
Check clamps and hose connections periodically for tightness to prevent air leakage.
Make sure all moving parts are clean and unobstructed by foreign objects.
Clean filter element every 3 months if applicable.
Grease and oil pivot points once every 3 months.
Lubricate daily if lift is in high cycle application.
Use 90-weight gear lube (SAE 85W 140 EP) to lubricate the pivots and shafts once every 3 months or as needed.
Grease the upper and lower wheel channels every 3 months or as needed.
Lubricate lock mechanism pivot points every 3 months or as needed.
Use overhead rigging when any maintenance beyond external lubrication is required.

Problem Possible Solution
Lift will not go up 1Check that air inlet is connected to the controller.
2 Check to ensure lockout is not engaged (if purchased as option).
3 Check air hoses to ensure no kinks or cuts in the line.
4Check to ensure no debris is preventing wheels from rolling in track.
5 Check regulator gauge is set to minimum of 80 psi (if purchased as option).
Lift is making a hissing noise 1 Check all air lines to ensure they are properly connected and
no leaks are occurring.
2 Check pressure relief valve.
If pressure relief valve is "leaking" lower lift immediately. The air bag
is in a state of over pressurization.
3 Check air bag for cuts or holes.
Lift is making a squeaking noise 1 Lubricate center joints and wheel tracks.

1. Layout the components of the 15244 KIT around the lift.
3. Position one side of the wing brackets over the appropriate lift blocks (see fig. 1).
4. Bolt the wing brackets to the lift as shown in fig. 1.
5. Slide the two tubes (#15247) into position on each side of the wing.
6. Slide the other wing into the tubes and line the mounting bracket over the lift blocks as shown in fig. 1.
8. Bolt the second set of wing brackets to the lift as shown in fig. 1.
9. Replace the old maximum capacity sticker with the new sticker. A stationary lift has 5000 lb. lifting capacity
after the 15244 KIT is installed.
10. Attach two ramps (10148) to each wing assembly (see fig. 1).
