1. Safety Instructions
Read all instructions in this manual before operating the lift unit to avoid severe injury or death. All of the steps and
procedures in this manual relate to the safe use of the lift system. Contact the manufacturer using the contact
information on the back cover of this manual if you have any questions about this unit or its instructions and warnings.
DO NOT use this product unless you know exactly what you are doing and are sufficiently trained and capable of using
the lift system safely (see the Warnings on page 4). When using the lift system, always adhere to basic safety
precautions, including the following:
IMPORTANT SAFETY INSTRUCTIONS
WARNING
Failure to know, understand, and obey the procedures, instructions and warnings contained in this
manual could result in severe injury or death.
DO NOT use the lift system to raise a vehicle by the frame or structural member. Lift vehicles
with the lift system only by the vehicle’s wheels (except when using manufacturer supplied
special-purpose adapters for their intended application).
The lift system is to be used only in sets of 2, 4, 6, or 8 lift units –NEVER as a single lift unit.
The only exception to this requirement is when using a single unit in Tire Mode as described in
Section 2.14. Lift only on the same axle.
DO NOT raise or lower one side of a vehicle (except when using Tire Mode). Lift units should
ALWAYS be used in pairs to lift wheels on opposite ends of the same axle.
DO NOT raise one end of a vehicle if the opposite end is supported by stands or another lifting
device. When using two lift units to raise one end of a vehicle, the opposite end of the vehicle
must be in contact with the ground, transmission in neutral and parking brake released. The only
exception to this requirement is when using the lift system in single or paired mode as described
in Section 2.11 of this manual.
DO NOT use the lift system in conjunction with any other equipment used to raise a vehicle
(e.g., any other jacks or lifts that are not part of the lift system).
DO NOT use blocks, non-factory supplied adapters or cribbing devices with the lift system.
No alterations shall be made to this product except those explicitly discussed in this manual
(e.g., use of optional adapters).
DO NOT place hands, feet, other body parts, or clothing between the lift carriage and the
column. There are potential pinch points that can injure hands and fingers or possibly grab
clothing and pull body parts into pinch points.
NEVER stand under the load or vehicle when it is being raised or lowered.
To reduce the risk of fire, do not operate equipment in the vicinity of open containers of
flammable liquids (gasoline).
To reduce the risk of electric shock, do not use on wet surfaces or expose to rain.
Do NOT remove the lifting forks for use on any different model of lift. Doing so could
result in instability of the lift where the forks are installed.
Do NOT remove base extensions from the lift. Both base extensions must remain in place at
all times. Removal of base extensions could result in instability of the lift.

CLHM-125EX-IOM-A Rev. 12/11/23
CAUTION
DO NOT use the lift system as a wheel dolly or for any other purpose than raising vehicles by
the wheels (except when using manufacturer supplied special-purpose adapters for their intended
application).
Always keep the covers closed on the lift units.
Care must be taken as burns can occur from touching hot parts.
Do not operate equipment with a damaged cord or if the equipment has been dropped or
damaged – until it has been examined by a qualified serviceman.
If an extension cord is necessary, a cord with a current rating equal to or more than that of the
equipment should be used. Cords rated for less current than the equipment may overheat. Care
should be taken to arrange the cord so that it will not be tripped over or pulled.
Adequate ventilation should be provided in the work area.
Keep hair, loose clothing, fingers, and all parts of body away from moving parts.
Use only as described in this manual. Use only manufacturer’s recommended attachments.
ALWAYS WEAR SAFETY GLASSES. Everyday eyeglasses only have impact resistant lenses,
they are NOT safety glasses.
To reduce the risk of electric shock or fire, never overload receptacles. Refer to markings for the
maximum load on receptacles.
NOTICE
Maximum capacity for an individual lift unit is listed on the lift unit’s ID decal. DO NOT
overload any individual lift unit in the lift system.
Do not let cord hang over edge of table, bench, or counter or come in contact with hot manifolds
or moving fan blades.
Never use the cord to pull the plug from the outlet. Grasp plug and pull to disconnect.
Let equipment cool completely before putting away.
The optimal operating ambient temperature range is 41-104°F (5-40°C). Use of lift units outside
this temperature range may result in degraded performance and reduced service life.
A qualified person should be consulted to address seismic loads as well as other state and local
requirements.

2. Operating Instructions
2.1 Prepare the Work Area
It is important that the surrounding area be properly chosen and prepared before raising a load. Refer to ANSI/ALI
ALIS for additional information.
a. Use the lift system only on hard surfaces capable of safely supporting the load. The surface must be strong
enough to support the weight of the lift units and the vehicle being raised. The ground pressure for each lift
unit is listed in the Specifications section. The ground pressure listed assumes the entire footprint of the lift
unit is in full contact with the floor.
b. Use the lift system only on level, even surfaces. A level surface is considered to be 3° slope or less. A surface
with 3° slope is equivalent to a 5% grade or 5/8 in. (15.9 mm) rise or drop per horizontal foot (304.8 mm) as
shown below. The surface must also be free of ripples, ridges, depressions, holes, or any undulation (e.g., a
seam in a concrete floor) that would cause only part of the lift unit’s footprint to be in contact with the floor.
c. Make sure there is adequate clearance above the highest point of the vehicle (including things like vehicle
exhaust pipes, air dams, etc.) so the vehicle does not contact any overhead objects when raised (e.g.
ceiling/roof structural components, duct work, hanging lights, heating/AC units, etc.). The lift system can
raise a vehicle as much as 69” (1,753 mm) (when four or more units are used together), but the vehicle will
extend vertically above this. The height of the lift unit alone when raised to 69” (1,753 mm) is 157.13” (3,991
mm).
d. Clear the work area (especially the area underneath the lift unit) of any unnecessary personnel, tools,
equipment, and other materials. No unauthorized personnel should be allowed in the work area where the lift
system is being used. A horizontal area 36” (914 mm) deep and 30” (762 mm) wide in front of the operation
panel must be kept clear while the lift is in operation.
e. The lift system must only be used in the environmental conditions listed below. WARNING! The lift system is
NOT approved for outdoor installation or use.
Do NOT use lift units when air speeds exceed 20 mph to avoid tipping or loss of load.
Do NOT leave lift units unattended. This will help to avoid inadvertent operation by untrained
operators and unforeseen changes in environmental conditions.
Do NOT use lift units in an area where moisture is present. There is a risk of electric shock if lift units
are used in a wet environment.
Do NOT charge lift units in a wet environment. Only charge lift units in a dry area to avoid risk of
electric shock.
If these conditions cannot be met, move the vehicle and lift units (separately) to an area where the lifting operation
can be performed safely. WARNING! NEVER attempt to move or reposition a lift unit when a vehicle is raised on
the lift unit.

2.2 Prepare the Vehicle
It is important that the vehicle be in proper condition before raising it off the floor.
a. The vehicle’s wheels (or rims; not the tires) must meet the minimum wheel diameter requirement shown in the
Specifications section on page 5 or else they could fall through the cradle of the lift carriage (for example, if
the tires deflate). See Section 2.3 for information about how to properly engage a tire.
b. Check that the tires on the vehicle are properly inflated and are in road-worthy condition. Make sure the
weight on any single tire does not exceed the rated capacity of its lift unit, as the total weight of the vehicle
may not be evenly distributed across all lifted tires. Also, be sure to consider the weight carried by
unsupported axles (i.e. a set of 4 lift units used to raise a vehicle with three axles).
2.3 Prepare the Lift Units
It is important to prepare the lift units so they can be used safely together.
a. Make sure to use an appropriate number of lift units for the type and weight of the vehicle to be lifted.
Determine how many lift units will be needed to raise the vehicle by calculating the weight of the vehicle and
the load applied to each lift unit when the vehicle is raised. NEVER exceed the rated capacity of an individual
lift unit. Also, the lift system is to be only used in sets where lift units are positioned on opposite ends of the
same axle– NEVER as a single lift unit or on only one side of a vehicle unless using Tire Mode as described
in Section 2.14.
b. Before each use, you should inspect each lift unit for any visible signs of wear or damage. See the Section 10
on page 34 for details about how to inspect the lift unit. WARNING! If you see any signs of wear or damage,
or if there is any indication that the lift unit is not performing normally, immediately take it out of service and
contact the manufacturer. NEVER use a lift unit that appears damaged in any way.
c. Before each use, plug in each lift unit and make sure the battery charger indicator light is green for both
batteries on each lift unit (see Section 5.2 on page 22 of this manual). If the light is not green, charge the
battery until the battery charger indicator light is green. Failure to fully charge the battery before use can
reduce the life of the battery.
d. Transport the lift units to the work area by either wheeling them manually or lifting and transporting them
with a forklift (see Section 4 on page 21). A lift unit can be wheeled to the work area over smooth, level
surfaces for short distances. Transport the lift units by forklift if traveling over longer distances and/or rough
or uneven surfaces.
e. Position the lift units at opposite ends of the same axle. If necessary, adjust the carriage lift arms (See Section
8) until they are wide enough to allow the lift pads to clear the tire tread. Make sure the lift pads cradle the
tires evenly and are aligned with the tire. Position the lift pads under the tire so the entire lift pad is under the
tire (see Figure 1). Lower the base to the ground using the handle once the lift unit is properly positioned (see
Section 4 for more information). WARNING! The carriage lift arms must be positioned so they are centered
on the lift carriage. NEVER use the lift unit with the lift arms positioned in an off-center position since this
can cause dangerous side loading of the lift unit.
f. Place the vehicle transmission in neutral and release the parking brake.

2.6 Information Panels
There are three information panels available on the Main Operation screen. Each panel can be directly accessed by
pushing on the corresponding button located near the top of the screen (see Section 2.5). The panels can also be
opened by swiping left and right in the middle of the screen. To return to the Main Operation screen either swipe left
until the panels are no longer shown or push the Truck Indicator button to return directly.
The first panel is the Battery Voltage panel and it can be accessed by pushing the Battery Charge Level button. The
Battery Voltage panel shows the real-time battery voltage of all the lifts in the lifting system. The voltages will update
even while the lift is raising or lowering. The Battery Voltage panel can be used to help identify and troubleshoot
battery issues. For example, if two lifts are lifting close to the same amount of weight the battery voltage while raising
should be similar on both lifts. If the battery voltage on one lift is significantly lower it may need to be charged or the
batteries may need to be replaced.
The second panel on the Main Operation screen is the Weight panel which can be opened by pushing the Weight
button. This panel will show the current weight being lifted by each of the lifts in the lifting system. It also shows the
total vehicle weight calculated by adding up the weight on each individual lift. The weight readings are most accurate
if all the lifts are stationary. All the weights shown are only estimates and should not be used in place of properly
calibrated and certified vehicle scales.
The third panel is the Radio Signal Strength panel and it is displayed when the Radio Setting button is pushed. This
panel shows the strength of the radio signal used to communicate among the lifts in the lift system. This information
can be helpful when determining the best radio settings for a given environment.
2.7 Raising/Lowering the Vehicle
Once the work area, vehicle, and lift units are prepared perform the following steps:
a. Position yourself at any one of the lift units.
b. Push and release the Enable button. The button color will change from red to green indicating the button is
ON. The button will stay ON (green) for 5 seconds after it is released. If no other buttons are pushed during
the 5 seconds the button will automatically turn OFF (red) at the end of the 5 seconds.
c. During the 5 seconds that the Enable button is ON (green), push and hold the Raise or Lower button to raise or
lower the vehicle. NOTE: The down stop catch pawls will automatically pull back and release when the
Lower button is pushed. During lowering the vehicle will automatically lower at a slower speed for the first 6
inches of travel. This slow start feature allows the vehicle to be gently placed on stands. After the first 6
inches of travel the vehicle will lower at normal speed for the remainder of time the Lower button is pushed.
d. As the vehicle raises or lowers the height indicator on the screen will update to show the current height.
e. When the vehicle is at the desired height release the Raise or Lower button.
f. If desired, Park mode can be activated on the lift unit to mechanically support the load on the down stop
system and relieve the hydraulic system pressure. Follow the steps in Section 2.12 to activate Park mode.
NOTE: Even if Park mode is not activated the down stop system will automatically stop the load from
lowering should the hydraulic system lose pressure.
g. Depending on the amount of time the vehicle will remain in the current position the lift system should be
either locked or turned off. If the vehicle will be raised or lowered before the end of the shift, the lift system
should be locked by following the steps in Section 2.9. If the vehicle will be left in the raised position longer
than 8 hours, turn the master on/off switch on all lift units in the system to the OFF position to conserve the
batteries.
WARNING! There are several important safety issues to consider when raising a vehicle or whenever a vehicle is in a
raised position, including:
All personnel should be instructed that the system should not be unlocked or restarted unless all objects and
personnel are out from underneath the vehicle and the vehicle, work area, and lift units are prepared for lifting
or lowering.

CLHM-125EX-IOM-A Rev. 12/11/23
If the lift units are to be removed from a raised vehicle, use only stands intended for this purpose. Use
appropriate vehicle support stands when a raised vehicle is to be left elevated for an extended amount of time.
Appropriate stands must be capable of supporting the load and they must be made specifically for high-rise
supporting.
NEVER attempt to climb up, climb on, or get in a raised vehicle. Do not open the vehicle’s doors or make
adjustments to the exterior when raised, as it could interfere with safe lowering of the vehicle.
NEVER start the vehicle’s motor when it is supported by the lift units or stands. Only start the engine when the
vehicle is firmly in contact with the ground and the lift units have been removed from the wheels.
NEVER attempt to move a vehicle horizontally by any means when it is raised on the lift system. Once the
vehicle is raised, it should only be moved up or down. Also, NEVER attempt to move or reposition a lift unit
when a vehicle is raised on the lift unit.
NEVER subject a lift unit to dynamic loading (i.e. “shock loading”). NEVER add objects or other weight to the
vehicle once it has been raised on the lift units.
If you experience any problems while raising the vehicle or while it is raised, consult Section 6 on page 25 and/or
Section 12 on page 36 of this manual.
2.8 Changing the Maximum Lift Height
The maximum lift height can be adjusted by pushing the Supervisor Settings button (see Section 2.15). A prompt will
appear asking for the password. The password is “1234” without the quotes. After entering the password and pressing
OK the Supervisor Settings screen will appear. Push on the box that shows the current max height. A window will
appear where a new maximum height can be entered. The allowed range for the maximum height is between 1.0 and
69.0 inches (2.5 – 175.2 cm). If a height outside this range is entered it will be ignored and the previous maximum
height will continue to be used. Confirm the box showing the current maximum height is correct before exiting from
this screen.
NOTE: The maximum height is adjustable on each individual lift unit. When multiple lift units are used together in a
system all lifts in the system will stop at the lowest maximum height setting of any individual lift. For example,
consider a system with four lifts. The maximum height is set at 48 inches (121.9 cm) on the first lift and 62 inches
(157.5 cm) on each of the second, third, and fourth lifts. When the lifts are operated all four of the lifts will stop at 48
inches (121.9 cm) since this is the lowest maximum height setting on any of the lifts in the system.
2.9 Locking the Lift System
a. Push the Options button (gear shaped button in the top left corner of the screen).
b. After the menu appears on the left side of the screen select the padlock button in the middle.
c. A message will appear asking whether Password Lock will be used. If No is selected then the system will
display a message showing it is now locked. If Yes is selected then a prompt will appear to create a password
that will be required to unlock the system. Enter a password and push OK. The system should now display a
message showing the system is locked.
d. When ready to unlock the system, return to the unit where the lock button was pushed (shown by the flashing
yellow position indicator) and push the Reset button. If Password Lock was not used the system will now be
unlocked. If Password Lock was used, enter the same password created in step c to unlock the system.
2.10 Lowering the Vehicle to the Ground
WARNING! To avoid serious injury or death, NEVER drive the vehicle off the lift units or attempt to move a vehicle
that is elevated by the lift system.
a. Clear the work area under the vehicle of all personnel, tools, and equipment. Make sure there are no obstruc-
tions under the vehicle or under the lift carriages of the lift system prior to lowering the vehicle to the ground.
b. If the lift system was locked, unlock the system by following the steps in Section 2.9. If the lift system was
turned off, follow the steps in Section 2.4 to reinitialize the system. If Park mode was activated, refer to
Section 2.12 prior to lowering the vehicle.
c. Position yourself at any one of the synchronized lift units.

d. Push and release the Enable button. The button color will change from red to green indicating the button is ON.
The button will stay ON (green) for 5 seconds after it is released. If no other buttons are pushed during the 5
seconds the button will automatically turn OFF (red) at the end of the 5 seconds.
e. During the 5 seconds that the Enable button is ON (green), push and hold the Lower button to lower the vehicle.
f. Release the Lower button when the vehicle is lowered to the floor and the lift carriages no longer contact the
tires. This condition will be indicated when the Stowed indicator turns blue.
g. Place the vehicle’s transmission in gear (or park) and engage the vehicle’s parking or air brake.
h. Move the lift units away from the work area and turn the master on/off switch to the OFF position. About 10
seconds after the master on/off switch is turned OFF the screen will display a message and power down. This will
ensure the lift units are ready to be synchronized for lifting in the future and conserve the batteries while the
lift system is not in use.
i. Completely recharge each lift unit after use.
2.11 Single/Paired Operation
In some situations it may be desirable to place only one wheel or one axle on stands instead of placing the entire
vehicle on stands. The lift system features a special mode of operation called single/paired mode to allow this. The
system can be placed in single/paired mode at any height.
a. If only one wheel of the vehicle will be placed on a stand, position yourself at the lift unit that is positioned on
that wheel of the vehicle. If one axle will be placed on stands, position yourself at one of the lift units on the
ends of the axle to be supported.
b. Push the Single/Paired button on the main operation screen shown in Section 2.5.
c. A screen will appear asking whether the system will be operated in single mode or paired mode. If only one
wheel will be supported on stands push the Single button. If one axle will be supported on stands push the
Paired button. Pushing the Exit button will return to the main operation screen.
d. The screen shown below (paired mode is shown in this example, single mode would be similar) will be
displayed on the lift unit where single or paired mode was initialized. All other lift units will be locked out
from operation and show a screen indicating this condition.
e. All the buttons shown function in the same way as described in Sections 2.5 and 2.6. The vehicle can be
raised or lowered as needed to place stands and support the vehicle. The distance the vehicle can be raised or
lowered is limited while in single or paired mode.
f. When all work that required the wheel/axle to be supported on a stand(s) has been completed, move the lift
unit(s) back into position under the wheel(s). The lift unit(s) can be raised or lowered to help with properly
positioning the lift carriage under the wheel(s). Push and release the Enable button and then within 5 seconds
push and release the Auto Return button. The lift unit(s) that was raised or lowered in single or paired mode
will automatically adjust its height to match the other units in the system and support the vehicle.
g. Once the lift unit(s) has adjusted its height to match the rest of the system, all the screens will return to the
screen shown in Section 2.5. The system will now operate as a whole with all lift units raising or lowering
together.

2.12 Park Mode
If desired, the load on the lift carriage can be transferred from the hydraulic cylinder to the mechanical down stop
system by activating Park mode. The following steps explain how to activate Park mode.
a. Follow the steps in Section 2.6 to position the vehicle at the desired working height.
b. Push and release the Enable button and within 5 seconds push and release the Park button. The lift system
will now lower until the down stop catch pawl engages the down stop slots on all lift units in the system.
c. Once all the units in the system have Parked, the Parked indicator will turn blue. The Lower button and Park
button will also disappear since the vehicle will need to be raised off the down stop catch pawl before it can be
lowered.
d. To exit Park mode, simply push and release the Enable button and then within 5 seconds push and hold the
Raise button until the Parked indicator light turns off. The vehicle can now be raised or lowered normally.
2.13 Options
The Options button displays additional buttons that are normally hidden from view on the screen. Pushing the Options
button displays a panel on the left side of the screen that includes the Lock button and the About button. To hide the
panel that is displayed when the Options button is pushed, push the Back button.
The Lock button is used as described in Section 2.9 to lock the system from operating. Pushing the About button
brings up a screen showing the contact information for the lift system manufacturer, the software versions currently
installed, and the battery voltage. To exit the About screen push the Back button.
2.14 Tire Mode
Tire mode is a special operating mode that must only be used to change a tire on a vehicle with dual axles. Tire mode
allows a single lift unit to raise to a limited maximum height. To use Tire Mode properly the following steps must be
followed:
a. The vehicle to be lifted must have dual axles.
b. The tire to be changed must be on one of the dual axles.
c. The lift unit must engage the wheel in front or behind of the tire to be changed on the same side of the vehicle
as the tire being changed. Chock the front and rear of the tire on the opposite end of the axle from the tire
being changed.
d. Follow the guidelines in Sections 2.1-2.3 to setup the work area, vehicle, and lift unit.
e. Activate Tire Mode by pushing the tire icon shown below.
f. The lift unit can now be operated as described in earlier sections. The lift can be raised, lowered, parked, and
locked. The maximum lifting height is limited to prevent lifting the vehicle too high causing it to become
unstable.
WARNING! Using Tire Mode for any other purpose than what is described in this section may cause a vehicle to be
lifted in an unstable manner resulting in tipping or loss of load. Tire mode must ONLY be used exactly as described in
this section. Failure to heed this warning could cause serious personal injury and/or property damage.
