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:
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
2.12. 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 2.9 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.

CLHM-IOM-A.doc
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 service man.
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.
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.

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 (at
maximum lift height) 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.
e. If the lift system is used outdoors the operator assumes all risk. Understanding that these are
portable lifts, it is foreseeable that they can and will be used outdoors. WARNING! If lift units
are used outdoors the following conditions must be met:
Do NOT use lift units when wind speeds or gusts exceed 20 mph to avoid tipping or loss of
load.
Do NOT leave lift units unattended when used outdoors to avoid inadvertent operation by
untrained operators and unforeseen changes in weather conditions.
Do NOT use lift units outdoors when precipitation of any type is falling or expected
during the time the units will be used. There is a risk of electric shock if lift units are used
while precipitation is falling.
Do NOT charge lift units while outdoors. Only charge lift units while indoors to avoid
risk of electric shock.
If these conditions cannot be met, move the vehicle and lift units (separately) to an indoor 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 2.12.
b. Before each use, you should inspect each lift unit for any visible signs of wear or damage. See
the Section 10 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 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 19). 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.

2.4 Control Box Initialization
a. Make sure the master on/off switch (see the “Component Identification” section on page 6) on all
lift units is turned to the OFF position.
b. Turn the master on/off switch of the first lift unit to the ON position. The green colored touch
screen power indicator light located just below the screen should turn on once the master on/off
switch is turned ON. It will take 15-20 seconds for the touch screen to completely start up and be
ready to use. The Home screen will be shown with a series of icons on the screen. Select the Lift
Program icon to start the program used to lift a vehicle. NOTE: After completing startup the
screen may automatically change to the Lift Program screen. If this occurs, then the step of
selecting the Lift Program icon can be skipped.
c. The control box will initialize and then the screen shown below will appear on the touch screen.
(NOTE: All screens shown in this manual are simplified versions of what is actually shown on
the display to help clarify button locations and functions.)
d. Select the desired radio settings. The default radio settings will be the settings selected the last
time the unit was used. Push the up and down arrows on the right side of the screen to change the
radio frequency and/or channel, if needed. All units that will be used together as a lift system to
lift a vehicle must be set to the same frequency and channel. There are 12 radio frequencies
available for use and the channel can range from 100-120 for each frequency. Refer to Section 7
for more information on selecting the radio settings. When the desired radio settings are shown,
push the Confirm button to advance to the next screen. NOTE: Do not rush and push the

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 and weight indicators on the screen will update to show
the current values. NOTE: The weight shown is only accurate when the lift unit is not raising or
lowering.
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 2.10 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 2.7. 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.
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 22
and/or Section 11 on page 32 of this manual.

step c will need to be entered to unlock the system.
2.8 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 obstructions 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 2.7. 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 2.10 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.
2.9 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.
2.10 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.

2.12 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.
2.13 Control Box Shutdown and Restart Procedure
The control box consists of two main parts- the control board and the touch screen which is an Android
tablet computer. Just like any computer the touch screen will need to be restarted (rebooted) if it operates
abnormally. Additionally, the control box should be shut down when the lift is not in use to conserve the
batteries. Follow the steps below to shutdown and restart the control box.
a. To shut down the control box turn the master on/off switch on the side of the lift unit to the OFF
position. After about 10 seconds a message will be displayed and the screen will power down.
The green touch screen power indicator light will also turn off once the control box has fully
powered down. NOTE: Do not restart the control box until the green touch screen power

4. Moving the Lift Unit in the Work Area
If a lift unit needs to be moved in the work area, either move it manually (with the handle and wheels) or
with a forklift. A lift unit can be manually wheeled to the work area over smooth, level surfaces for short
distances. WARNING! Jolting caused by the lift unit’s wheels catching on uneven surfaces can cause
physical strain and personal injury. A lift unit should be transported by forklift if traveling over longer
distances and/or rough or uneven surfaces. A forklift must also be used if the lift unit is being removed from
a pallet (e.g., when the lift unit is shipped to the customer).
4.1 Moving the Lift Unit with the Handle
To move the lift unit for positioning, push down on the actuating lever (see Figure 3) to move it into the
Raise position. Then, pump the handle by pulling it toward you until the base of the lift unit is raised the
desired amount above the floor. The base can be raised a maximum of about 1 inch. Once the base is at
the desired height, move the lever up to the Neutral position. The lift unit can now be maneuvered to the
desired location. Once the lift unit has been positioned, the base should be lowered to the floor. The base
is lowered by gently pulling up on the actuating lever to move it into the Lower position. The farther the
actuating lever is pulled up the faster the base will lower to the floor. Remember, the base of the lift unit
should always be lowered to the floor prior to lifting a vehicle.
4.2 Moving the Lift Unit with a Forklift
You can move the lift unit by forklift, using the two forklift pockets (see Figure 4) provided on each lift
unit. Be sure the forklift forks are fully inserted into the forklift pockets and the lift carriage is fully
lowered before lifting. Use only these pockets to move the lift units with a forklift.

5. Battery Information
5.1 Battery Type
Each lift unit is equipped at the factory with two deep cycle batteries. These batteries have been selected to
match the usage conditions found on the lift unit. If replacement batteries are needed, it is recommended to
use only the same brand and model of batteries originally supplied with the lift unit. Do NOT mix old and
new batteries or use different types/brands of batteries on the same lift unit.
5.2 Charging the Battery
The battery should be charged after each use to ensure the longest possible battery life and to avoid service
interruptions. The batteries used on all lift system models can be charged before they are completely
discharged and not develop a “memory”. The battery life and level of charge will be greatly improved if
the batteries are charged before they are deeply discharged. NOTICE: Only use the supplied battery
charger to charge the batteries. The supplied battery charger is designed for the type of batteries used on
the lift units. Use of a charger not designed for the type of batteries on the lift units may cause under or
overcharging that will reduce the life and capacity of the batteries.
The on-board battery charger is mounted inside the sheet metal cabinet above the door as shown in Figure
5. To charge the battery a suitable extension cord (see Table 1 below for proper cord selection) should be
connected to the battery charger cord socket located on the left side of the lift unit. Always use a grounded
extension cord with a plug style that matches the plug for the battery charger cord socket. Inspect the
condition of the cord and plug and only use if they are free of defects. The amperage drawn by the battery
charger is shown in Table 1. Eight lift units (in any combination of models) should be able to charge
simultaneously on the same circuit powered by a 20 Amp circuit breaker.

The battery charger provided on each lift unit is a “smart” charger. There are two battery charger indicator
lights (one for each battery) located above the door that indicate the status of the battery charger when it is
plugged in (See Figure 5). The battery charger automatically goes through several different stages of
