conforming to the installation instructions for the lift. Consult lift installation instructions
for concrete thickness and strength requirements. Ensure clearance around and above
lift conforms to installation instructions for the lift.
ATTENTION! This lift is intended for indoor installation only. It is
prohibited to install this product outdoors. Operating environment
temperature range should be 41 –104 °F (5 –40 °C). Failure to adhere
will result in decertification, loss of warranty, and possible damage to the
equipment.
Installation of lifts shall be performed in accordance with ANSO/ALI ALIS, Safety
Requirements for Installation and Service of Automotive Lifts
For additional safety instructions regarding lifting, lift types, warning labels, preparing to
lift, vehicle spotting, vehicle lifting, maintaining load stability, emergency procedures,
vehicle lowering, lift limitations, lift maintenance, good shop practices, installation,
operator training and owner/employer responsibilities, please refer to “Lifting It Right”

3.0 Safety Instructions
Never allow unauthorized or untrained persons to operate the Jack Beam.
Thoroughly train all employees in the use and care of the Jack Beam.
Allow 12” minimum clearance between vehicle and nearest overhead obstruction
before raising vehicle above runways. This number is dependent on the number
and size of stack adapters used. For each stack adapter, minus the length of
each from 12”. Failure to comply can result in vehicle damage and/or personal
injury.
To avoid personal injury and/or property damage, the Jack Beam must only be
operated by trained personnel.
Never overload the Jack Beam. Capacity of Jack Beam is stated on nameplate,
DO NOT exceed.
Observe and avoid any pinch point areas of the Jack Beam.
Never operate a Jack Beam that is not in proper working order or in a manner not
recommended by the vehicle or Jack Beam manufacturer.
Always ensure that the mechanical safety is engaged whenever a vehicle is
supported by the Jack Beam.
Do not use different length stack adapter on each arm. Stack adapter must be
used in pairs.
Load evenly; do not place weight on one side of the jack.

4.0 Positioning of Jacking Beam on Lift
Note: The Jack Beam must be positioned on the lift correctly prior to usage.
1. Place Jack Beams on runway tracks at front and rear of lift with the pump of each
facing to the front and rear.
a. Adjust the roller adapter to center the jack body between jack rails.
b. Ensure wheels are on the tracks and roll freely.
c. Tighten roller adapter jam nuts
2. Attach recoil hose to the bulkhead fitting at the rear of each Jack Beam, and then
other ends to the ‘T’ fitting on lift.
a. The Jack Beam is shipped pre-assembled to install at the front of the lift.
The air connection bracket is on the rear left side of the Jack Beam.
b. To install the Jack Beam at the rear of the lift, the air connection bracket
must be removed and reinstalled on the rear right side. Disconnect the
1/4” polytube, reroute, cut to length and reinstall.
c. Check reservoir for hydraulic oil and fill as needed.

3. To prevent oil leaks during shipment, a metal air bleed knob is installed and
tightened to ensure a good seal. Loosen it by turning counterclockwise before
use.
4. Prior to placing vehicle on lift, raise and lower the Jack Beam multiple times and
check for air and hydraulic leaks.
5. See sections “5.0 Raising the Jack Beam” and “6.0 Lowering the Jack Beam” for
operation instructions.
6. Adjust the lock pawl handle.
a. Confirm the lock pawl is engaged properly on the third lock position. See
sections “5.0 Raising the Jack Beam” and “6.0 Lowering the Jack Beam”
for operation instructions
b. Adjust the shim to contact the extension rod tightly.
c. Tighten two nuts.
d. Check the lock pawl seats properly against the scissor lock on a weekly
basis. If needed, repeat a, b, c steps.

5.0 Raising the Jack Beam
1. Prior to placing vehicle on lift, check the operation of the Jack Beam.
2. Press the "PUMP" end on the air/hydraulic pump and hold until jacking Beam is
at full working height.
3. As lift travels up:
Ensure the mechanical safety falls into place at all safety positions.
Check system for air and hydraulic leaks.
4. To place a vehicle on the lift, see section “8.0 Positioning of Vehicle on Jack
Beam” for instructions.

6.0 Lowering the Jack Beam
1. To lower the Jack Beam, first raise the Jack Beam up off the mechanical safety
lock.
2. Disengage the safety lock by lifting and holding the Safety Release Handle.
3. Press the “RELEASE" handle down on the pump to release pressure allowing the
jacking Beam to lower to its full down position.
4. Once Jack Beam is completely collapsed, release the safety and lowering
handles.
5. If lowering from the 2nd or 3rd lock position to the 1st lock position, repeat steps 1
to 4. You may release the safety handle once the 2nd safety has passed.
6. Lower the Jack Beam onto each safety (Note: there are three safety positions to
allow for multiple working heights).
NOTE: The Safety Release handle is gravity returned to “reset” the safety.
After reading these instructions, get familiar with the controls by running the
Jack Beam through a few cycles before loading vehicle on lift.
7.0 Storage Position of Jack Beam
In order to allow for adequate vehicle drive-on clearance,
1. When not in use, store Jack Beams towards the center of the lift.
2. Ensure lift is fully collapsed.
3. Remove lifting pads if additional clearance is required
8.0 Positioning of Vehicle on Jack Beam
The WHEELFREE®jack system has a low profile design, however; this may not be
suited for all vehicles.
Cautionary steps to consider before driving a vehicle over a rolling jack onto or off of a
lift.
Inspect the underside of the vehicle for low hanging obstructions.
Inspect the vehicle for points of interference
Position rear rolling jack Beam forward from the rear of the lift.
Jack pads and extensions must be removed from the jack.
Make certain the jack is in is fully lowered position
Floor areas must be clear from objects that may be in the path when lowering the
lift and/or jack Beam
Air supply must be maintained
