1.1 Warnings
Read all instructions in this manual before
operating the lift unit to avoid severe injury or
death. All 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 Owner/operator
responsibilities). When using the lift system, always
adhere to basic safety precautions, including the
following:
Anyone who operates this jack must read and
understand all the instructions and warnings
provided with this lift before being allowed to
use it. All operators must be careful, competent,
trained, and qualified in the safe operation of the lift.
The owner (or other responsible individual) must
ensure that any operator always observes the pr oper
safety procedures for using this lift. Ifthe operator does
not read well or is not fluent in English, the owner /
manager must read and review the instructions and
warnings in the manual with the operator in the
operator's native language to be sure that the operator
will use the lift properly.
The owner / manager must keep this manual for
future reference, and make sure the warning labels
on the equipment are legible and intact at all times.
Replacement labels and manuals are available from the
manufacturer. Call the manufacturer using the contact
information on the back cover ofthis manualif you have
any questions.
Make sure the load does not exceed the
maximum capacity of the lift. Maximum capacityfor
an individual lift unit is listed on the lift unit’s ID decal.
Do not overload any individual lift unit in the lift system.
Never modify the product in anyway. Modifications
(other than those explicitly discussed in this manual –
e.g., use of optional adapters) may cause the lift to
perform improperly, resulting in injury or death.
Always use lift on a hard level surface, capable
of sustaining the load. Be sure surface is clean and
free of debris, cracks, and chips.
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 manufacturers 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. Lift only
on the same axle.
Fig. 1: Lift on 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 “Single/paired mode”.
Do not raise or lower one side of a vehicle (except
when using Tire Mode). Lift units shouldALWAYS be
usedin pairs to lift wheels on opposite ends of the same
axle.
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).
Never use blocks, adapters, or accessories that
have not been provided by the manufacturer, or
cribbing devices of any kind with this lift system.
Do not place hands, feet, other body parts, or
clothing on or near the lift table. There are potential
pinch points that can injure hands and fingers or
possibly grab clothing and pull body parts into pinch
points.

Operation
8. Ope
r ation
8.1 Preparing 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.
1. 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 Specification section. The ground
pressure listed assumes the entire footprint of the lift
unit is in full contact with the floor. Hot asphalt can
become soft and should be avoided to prevent
property damage or an unsafe situation.
2. 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)
(See Fig. 4 below. Note also that for each degree of
slope a surface rises or drops 0.210 in. (5.33 mm) per
horizontal foot (304.8 mm)). The surface must also be
free of ripples, ridges, depressions, holes, or any
undulation (e.g., a seamin a concrete floor) that would
cause only part of the lift unit’s footprint to be in
contact with the floor
.
Fig. 5: Slope ofground under lift
3. 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” (1753 mm, 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” (3991 mm).
4. Clear the workarea (especially the areaunderneath the
lift unit) of any unnecessary personnel, tools,
equipment, and other materials. No unauthorized
CML Series | 11 | en
personnel should be allowed in the work area where
the lifts are being used. Ser
5. 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.
This will help 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 cannotbe 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.
8.2 Prepare the vehicle
It is important that the vehicle be in proper condition
before raising it off the floor.
1. The vehicle’s wheels (or rims; not the tires) must meet
the minimum wheel diameter requirement shown in the
Specificationssection or else they could fall through the
cradle of the lift carriage (for example, if the tires
deflate). See section of Lift Unit Preparation for
information on properly engaging a tire.
2. Check that the tires on the vehicle are properly inflated
and are in road-worthy condition. Make sure the we ight
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 usedto raise a vehicle withthree axles).



en | 12 | CML Series Operation
8.3 Prepare the lift units
It is important to prepare the lift units so they can be
used safely together.
1. Make sure to use an appropriate number of lift units for
the type andweightofthe 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
appliedto each liftunit when the vehicle israised. 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 Tire Mode
section.
2. Before each use, you should inspect each lift unit for
anyvisible signsof wear or damage.See the “Structural
Inspection” section on page 27 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.
3.Before each use, plugin eachlift unit and make sure the
battery charger indicator lightis green for both batteries
on each lift unit (See “Charging the Battery” section). If
the light is not green,charge the batteryuntilthe battery
charger indicator light is green. Failure to fully charge
the battery before use can reduce the life of the battery
.
4. Transport the lift units to the work area by wheeling
them manually or lifting and transporting them with a
forklift (See “Moving lift with a forklift section”). 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/uneven surfaces.
5. Position the lift units at opposite ends of the same axle.
If necessary, adjust the carriage lift arms (See Carriage
width adjustment section) 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 (Fig. 6). Lower the base to the
ground using the handle once the lift unit is properly
positioned.
The carriage lift arms must be positioned so they are
centered on the lift carriage. Neveruse the lift unit with
the lift arms positioned in an off-center position since
this can cause dangerous side loading of the lift unit.

Operation
8.4 Control Box initialization
1. Make sure the master on/off switch (see “Component
identification” section) on each lift unit and the Touch
Screen Controller is set to the OFFposition.
2. 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 Main Menu sc reen will
be shown with a series of icons on the screen. Select
the Lift Program button to start program used to lift a
vehicle.
 After completing startup, the screen may automatically
change to the Lift Program screen. If this occurs, the
step of selecting the Lift Program button can be
skipped.
3. The control box will initialize, and the screen shown
below will appear on the touch screen.
All screensshown in this manual are simplified versions

4. Select the desired radio settings. The default radio
settings will be the settings selected the last time the
unit was used. Touch the screen on top of the Settings
on the right side of the screen andthen slide up or down
to scroll through the settings. Then, touch to select the
desired radio setting. All units that will be used together
as a lift system to lift a vehicle must be set to the same
radio setting. There are 12 radio frequencies available
for use and 20 different channels that can be used for
each frequency. When the desired radio settings are
shown, push the CONFIRM button to advance to the
next screen.
Do not rush and push the CONFIRM button before the
control box has completely initialized. Wait until the

8.6 Information Panels
There are three information panels available on the Main
Operation screen. Each panel can be directly accessedby
pushing on the corresponding button locatednear the top
of the screen. 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.
8.7 Raising/lowering the Vehicle
Once the work area, vehicle, and lift units are prepared ,
perform the following steps:
1. Position yourself at any one of the lift units.
2. 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.
3. 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.
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
LOWERbutton is pushed.
4. As the vehicle raises or lowers, the height indicators on
the screen will update to show the current height.
5. When the vehicle is at the desired height, release the
RAISEor LOWERbutton.
6. If desired, Park mode can be activated on the lift unit to
mechanicallysupportthe load on the down stop system
and relieve the hydraulic system pressure. See “Park
mode” section on page 19 for direction on how to
activate Park mode.
Even if Park mode is not activated the down stop
system will automatically stop the load from lowering
should the hydraulic system lose pressure.
7. Depending on the amountof 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 below. 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.
There are several important safety issues to c on sider
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 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 ve hicle,
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
supportingthe load andthey mustbe made specifically
for high-rise supporting.

en | 16 | CML Series Operation

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 lifts. 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 the “Eme rgency
procedures” section on page 25 and/or the
“Troubleshooting” section on page 32 of this manual.

8.8 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 maximumheight
can be entered. The allowedrange for the maximumheight
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 heightwill continue tobe 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.
8.9 Locking the lift system
1. Push the OPTIONS button (gear shaped button in the
top left corner of the screen).
2. After the menu appears on the left side of the screen
select the padlock button in the middle.
3. 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.
4. 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 R ESET
button. If Password Lock was not used the system will
now be unlocked. IfPasswordLockwas used, e nter the
same password created in step 3 to unlock the system.

Operation CML Series | 19 | en
8.11 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 featuresa special mode
of operation called single/paired mode to allow this. The
system can be placed in single/paired mode at any
height.
1. 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.
2. Push the SINGLE/PAIRED button on the main
operation screen shown in Section 8.5.
3. 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.
4. 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.
Fig. 11: Paired mode operat
ion
5. All the buttons shown function in the same way as
described in Section 8.5 and 8.6. The vehicle can
be raisedor loweredas neededtoplace standsand
support the vehicle. The distance the vehicle canbe
raised or lowered is limited while in single or paired
mode.
6. When all work has been completed that required
the wheel/axle to be supported on a stand(s), move
the lift unit(s) back into position under the wheels.
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.
7. Once the lift(s) has adjusted its height to match the
rest of the system, all the screens will return to the
screen shown in Section 8.5. The system will now
operate as a whole with all lift units raising or
lowering together.

en | 20 | CML Series
8.12 Park mode
If desired, the load on the lift table 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.
1. Follow the steps in Section 8.7 to position the vehicle
at the desired working height.
2. Push and release ENABLE button, then within 5
seconds, push and release PARK button. The lift
system will now lower until the down stop catch pawl
engages down stop slots on all lift units in the system.
NOTE: The lifts will only park if they are all above th e
same down stop lug. If they are not all above th e
same down stop lug, the “park window error” will be
indicated and the lifts will have to be Raised or
Lowered until all the lifts are above the same down
stop lug.
3. Once all the units in the system have Parked, the
PARKED indicator will turn blue. The LOWER button
will also disappear since the vehicle will need to be
raised off the down stop lugs before it can be lowered.
4. 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.
8.13 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 8.9 to
lock the system from operating. Pushing the ABOUT
button brings up a screen showing the contactinformation
for the lift system manufacturer, the software versions
currently installed and the battery voltage. To exit the
About screen, push the BACK button.
Operation
8.14 Tiremode
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:
1. The vehicle to be lifted must have dual axles.
2. The tire to be changedmustbe on one of the dualaxles.
3. 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.
4. Follow the guidelines in Sections 8.1-8.3 to setup the
work area, vehicle, and lift unit.
5. Activate Tire Mode by pushing the tire icon shown
below.
Fig. 12: Tire mode operation
6. The lift unit can now be operated as described in ea rlier
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.
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
