FUNCTION AND PURPOSE OF LIFT
This lift is designed to lift loads—it is not designed to support loads once lifted. Thus, this lift must always be used
in conjunction with appropriate and adequate vehicle support stands. Also, this lift is designed to lift certain loads
(e.g., vehicles, trailers) in specific ways (one end and never on the side). NEVER attempt to use this lift in ways for
which it was not designed. If you have lifting needs that cannot be met by this lift, do not attempt to modify the
lift or use it for purposes other than those for which it was designed—always use a lifting device that is
appropriate for the load. Do not use adapters and/or attachments from other units. Consult parts list for
adapters and/or attachments that can be used on this product, not to exceed maximum lift height of 50”.
Contact the manufacturer if you have any questions about other lifts or the appropriateness of this lift for
different types of jobs.
1.OPERATING INSTRUCTIONS
WARNING
Using the jack to raise vehicles requires several steps that must be followed each and every time the jack is
used.
1. Inspect the jack for signs of wear or damage.
2. Transport the jack to the work area.
3. Select appropriate vehicle support stands and bring them to the immediate work area.
4. Prepare the surrounding area before using the jack.
5. Identify lifting points and prepare the load for lifting.
6. Raise the vehicle.
7. Use appropriate vehicle support stands.
8. Lower the vehicle.
Each of these steps is discussed in detail in the following sections. Failure to follow all these instructions can lead
to serious injury or death.
1.1 Inspect the Jack for Signs of Wear or Damage
Before each use, you should inspect the jack for any visible signs of wear or damage. See the “Inspecting the
Lift” section for details about how to inspect the jack.
If you see any signs of wear or damage, or if there is any indication that the jack is not
performing normally, immediately take it out of service and call the manufacturer using the
contact information on the back cover of this manual. Never use a jack that appears
damaged in any way.
1.2 Transport the Jack to the Work Area
Transport the jack to the work area by pushing it in the fully lowered position. When moving this lift around the
shop floor, it must never be moved while in the raised position. Wheel the jack only across hard level surfaces.
Use only the handles provided as the means by which you grab the lift and move it. The lift should NEVER be
tilted backwards for any reason (i.e., to clear an obstacle on the floor, to move under an elevated obstacle, etc.).
Tilting the lift can cause the lift to fall backwards onto the operator or someone who might be nearby. If the lift
ever does fall, for whatever reason, get out of the way immediately—NEVER try to catch the lift if it falls
backwards.
WARNING

6
Jolting caused by the wheels catching on uneven surfaces can cause physical strain and
personal injury.
1.3 Select Appropriate Vehicle Support Stands and Bring Them to the
Immediate Work Area
It is important that appropriate vehicle support stands are used.
Use appropriate stands to support the load immediately after lifting. NEVER use the jack to
support a load. Failure to follow all of these instructions can result in jack instability and loss
of a load.
1.4 Prepare the Surrounding Area Before Using the Jack
It is important that the surrounding area be prepared properly before raising a load.
Failure to follow all of these instructions can result in jack instability and loss of a load:
Use the jack only on hard, level surfaces capable of safely supporting the load.
Clear the surrounding area of personnel, tools, equipment, and make sure appropriate
vehicle support stands available for use in the immediate area.
If these conditions cannot be met, move the vehicle or trailer to an area where the lift can be performed safely.
1.5 Identify a Lift Point, Prepare the Load for Lifting, and Chock Wheels
1. Identify a vehicle manufacturer recommended lift point on the vehicle or trailer that will be lifted. If lifting
a trailer remove any load on or in the trailer.
2. Chock the wheels on the end of the vehicle or trailer that will remain on the ground. The chocks must be
placed on the outside (farthest from the end being lifted) end of the wheels.
3. Place the vehicle in neutral and disengage the parking brake.
When selecting a lift point, it is very important that you consider the following:
Position the jack so that, as the vehicle or trailer is lifted, the load will be balanced on the
wheels or landing gear that remains on the ground.
Only use approved manufacturer’s recommended lifting points on vehicles and trailers.
1.5.1 Adjusting the Height of the Saddles
On occasion, it may be necessary to adjust the height of the saddles in order to make good contact with
the lift points of the load (i.e., if there is a distance between the saddle in the lowest position and the lift
point on the load). The height of the saddles can be adjusted by removing the pin from the saddle,
raising the saddle and reinserting the pin into the hole. The pin should always be placed all the way
through the saddle arm support. Also, both saddles must be pinned at the same height when lifting a
load. DO NOT make saddle height adjustments if these conditions cannot be met. Follow the safety
instructions on the lift for positioning the saddles on the lift.

1.6 Operating the Air Valve to Raise a Load
1. Once the lift has been positioned under the load to be lifted (according to the safety instructions on the lift),
operate the air valve handle slowly to carefully raise the saddles to engage (capture) the lift points of the
vehicle (see Figure 1).
2. After the saddles make contact with the lift points, visually recheck their position to be sure the load is
properly seated for lifting. Be careful not to put any part of your body (e.g., arms, hands, fingers, etc.)
between the saddle and the lift point on the vehicle. When raising or lowering, the operator should check to
make sure nobody else is in the immediate work area.
3. Continue raising the load to a height slightly above the desired working height by holding the air valve
handle in the position to raise. It is necessary to raise above the desired working height since the load will
be lowered onto vehicle support stands at the desired working height.
4. Lower the lift onto the nearest down stop lug by operating the air valve handle to exhaust air (see Figure 2).
Do not operate the down stop release lever or else the lift will not properly engage the down stop lug. Be
sure to continue exhausting air even after the lift engages the down stop lug to ensure there is no air
remaining in the cylinder before continuing.
When using this lift to raise a load you must consider the following:
NEVER allow any part of your body to pass under the load until the lift is resting on a
down stop lug and all air has been exhausted from the cylinder. This lift is a lifting
device only- it is not intended to support a vehicle for extended periods of time. Only
go under a load supported by this lift to place and remove vehicle support stands.
Failure to follow these instructions could result in serious injury and/or death.
NEVER use this lift in conjunction with any other jack or lift.
NEVER use this lift to raise one end of a load if the other end of the load is not resting on
the ground.

1.7 Use Appropriate Vehicle Support Stands
1. After the lift is resting on a down stop lug and all air has been exhausted from the cylinder place
appropriate vehicle support stands under the load. Be sure the stands have adequate capacity to support
the load and are placed under the vehicle at manufacturer recommended lifting points. Follow all instructions
provided with the stands while placing and using the stands.
2. Raise the lift until it is clear of the down stop lug by operating the air valve handle as shown in Figure 1.
3. Operate the air valve handle and the down stop release lever as shown in Figure 3 to lower the load until it
is supported on the vehicle support stands.
4. After verifying the load is safely supported by the vehicle support stands remove the lift from the work area.
1.8 Lowering the Load
1. To lower the load, begin by following the process outlined in Sections 1.1 through 1.5.
2. Once the saddles of the lift have been positioned properly according to these steps, raise the lift slowly to
lift the load off the vehicle support stands. Lift the load until the lift is above the next down stop lug.
3. Operate the air valve handle as shown in Figure 2 to lower the lift onto the down stop lug. Be sure to
continue exhausting air even after the lift engages the down stop lug to ensure there is no air remaining in
the cylinder before continuing.
4. Remove the vehicle support stands from underneath the vehicle.
5. Visually inspect the area beneath the vehicle to ensure that it is free of any obstructions and make sure that
no one else is in the immediate work area before preparing to lower the vehicle to the ground.
6. Raise the lift slowly by operating the air valve handle as shown in Figure 1. Raise until the lift clears the
down stop lug.
7. Lower the lift by pushing on the down stop release lever and holding the air valve handle (see Figure 3) until
the lift can be removed from under the vehicle. Air must bleed off for a few seconds before the lift will start
lowering.
8. After lowering the load, put the vehicle in park and engage the brakes before removing the lift and the
wheel chocks.
To avoid a crushing injury, you must make sure that no objects or body parts are on the
ground near the lift platform whenever the lift and/or the load are being lowered.

1.9 Lifting a Trailer
In addition to lifting vehicles, this lift can be used to lift trailers. It is important that the box or flat bed trailers be
EMPTY prior to lifting to ensure that any weight imbalance in the load does not cause a tip-over when the load is
lifted. Also, box and flat bed trailers should be disconnected from their tractors and should be resting on their
front supports.
Do not lift the trailer by the ICC bumper if the trailer manufacturer has not designated it as an approved lifting
point. In preparing to lift an EMPTY box or flat bed trailer, you should inspect the rear ICC bumper to make
sure it is not bent or damaged in any way. If this bumper is damaged, consult the manufacturer to determine if
there is an alternate lifting location. Roll the lift into place; make sure it is centered on the trailer and bumper.
Make sure that the lift saddles on the lift frame fully engage (cradle) the bottom of the bumper and that the
saddles are positioned front to back to ensure that the bumper is resting on the face of the saddle and is
captured between the saddle horns—this prevents the bumper from slipping off the saddles when lifted.
The proper lift points on an ICC bumper are directly beneath the vehicle structure members (see Figure 4), which
connect with the frame and are approximately 34 inches apart in width. Slowly raise the lift frame to engage
the bottom of the bumper. Then follow the steps outlined in Sections 1.6 thru 1.8 to raise the trailer, support the
trailer on vehicle stands, and finally lower the trailer.

2.MAINTENANCE INSTRUCTIONS
WARNING
To prevent serious injury or death from a falling vehicle, all inspection and maintenance procedures must be
performed after the lift has been removed from service. Position the lifts so you have clear access to all sides
of the lift for inspection and service.
The owner must inspect, or appoint a knowledgeable person to inspect, the lift. Visual inspection should be made
before each use of lift, checking for abnormal conditions. Regular inspections should be made weekly for daily
use and monthly for intermittent use. Each jack must be inspected immediately if subjected to an abnormal load
or shock. Any jack which appears to be damaged in any way, is found to be badly worn, or operates
abnormally shall be removed from service until necessary repairs are made.
1. All warning and capacity labels should be readable and complete. Wash external surfaces of jack, labels,
and decals with a mild soap solution.
2.1 Lubrication
1. Lubricate the pneumatic wheels, swivel caster, and sliding portions of the jack monthly.
2.2 Air Valve Cleaning Instructions
1. Remove the valve cover.
2. Remove the valve from the 1/4" pipe nipple.
3. Remove the brass handle in the valve body.
4. Use a stiff wire or pin punch to push the spools out of the valve body.

3.STRUCTURAL INSPECTION
WARNING
To prevent serious injury or death from a falling vehicle, all inspection and maintenance procedures must be
performed after the jack has been removed from service. Position the lift so you have clear access to all sides
of the lift for inspection and service.
WARNING
The jack must be removed from service and inspected for damage immediately if the jack is subjected to an
abnormal shock or load. Never return the jack to service until all damaged components have been properly
repaired or replaced. Always test the lift and verify proper operation before returning the jack to service.
Failure to heed this warning may result in personal and / or property damage.
NOTICE
The owner must inspect, or appoint a knowledgeable person to inspect the jack for signs of corrosion and / or
excessive wear. Visual inspection should be made before each use of jack, checking for abnormal conditions.
Regular inspections should be made weekly for daily use and monthly for intermittent use. Each jack must be
inspected immediately if subjected to an abnormal load or shock. Any jack which appears to be damaged in
any way, is found to be badly worn, or operates abnormally shall be removed from service until necessary
repairs are made.
Inspect the lift for any cracks, chips, or signs of excessive wear. Visually inspect the welds.
If any irregularities or problems are detected during an inspection, the jack must be removed from service
immediately and repaired. Contact the manufacturer using the contact information on the back cover of this
manual.
3.1 Inspecting the Lift
Perform an inspection of the lift before each use. NEVER perform inspections while the lift is in operation (i.e.,
lifting a load). An inspection consists of the following items:
Visually inspect all components of the lift for signs of corrosion and/or excessive wear.
Inspect the lift for any cracks, chips, or signs of excessive wear. Visually inspect the welds.
Inspect the saddle support adjusting pins for signs of excessive wear or deformations. Also, inspect the
holes on the saddle arm for elongation. If pins cannot be removed from the saddle arms or if there is
elongation of the holes, then it is likely that the lift has been overloaded and should be taken out of
service until it can be repaired.
Verify that all warning and instructions decals (see Figure 3 for locations) are in place and legible before
the lift is put back in service. If any decals are missing or illegible, contact the manufacturer for
replacements.
If there is any evidence of hydraulic oil leaking from underneath this lift, the lift must be removed for
service and returned to the manufacturer for servicing. This unit is equipped with a non-serviceable
vertical restraint and must be returned to the factory for repair. Contact the manufacturer as soon as
possible.
