INSTALLATION REQUIREMENTS AND TOOLS / SUPPLIES

6

Foundation

Important: It is the user’s responsibility to provide a satisfactory installation area for the lift. Lifts

should only be installed on level concrete floors with a minimum thickness of four inches (4") or
102 mm. Concrete must have a minimum strength of 3500 psi and should be aged thirty (30)
days prior to installation. Please consult an architect, contractor or engineer if doubt exists as to
the strength and feasibility of the floor to enable proper lift installation and operation. Do not use
on asphalt. Do not use on a suspended floor without approval from a licensed structural
engineer.

A qualified person should be consulted to address seismic loads and other local or state
requirements.

It is the user’s responsibility to provide all wiring for electrical hook-up prior to installation and to
insure that the electrical installation conforms to local building codes. Where required, it is the
user’s responsibility to provide an electrical isolation switch located in close proximity to the lift
that will enable emergency stop capability and isolate electrical power from the lift for any
servicing requirements.

Tools / Supplies

1. Cutting device to remove packaging.

2. Metric wrenches.

3. 6 mm allen wrench

4. Clean funnel for adding hydraulic oil.

5. Clean new * AW-32 Hydraulic Oil
Hydraulic Oil needed per model

Installation Instructions

When the lift arrives on site:

Check for any freight damages. The shipment should be thoroughly inspected as soon
as it is received. The signed bill of lading is acknowledgement by the carrier of receipt in
good condition of shipment covered by our invoice. If any of the goods called for on your
bill of lading are shorted or damaged, do not accept them until the carrier makes a
notation on the freight bill of the missing or damaged goods. Do this for your own
protection. Check the contents of the accessory and hardware boxes to make sure no
parts are missing.

NOTE: IT IS DIFFICULT TO COLLECT FOR LOSS OR DAMAGE AFTER YOU HAVE
GIVEN THE CARRIER A CLEAR RECEIPT. THE LIFT MANUFACTURER IS NOT
RESPONSIBLE FOR ANY FREIGHT DAMAGE.

Unpacking Procedure

 Remove all plastic wrap and cardboard. Be careful not to cut into the lower hydraulic

hoses and fittings or to scratch the paint or damage the safety decals.

 Use a 13 mm wrench remove the forklift brackets attached on the top of the carriage and /

or the column sides.

 Carefully open the parts carton, avoid cutting the enclosed communication cables.
 Remove all of the cables, column cover, spare parts and document packet.

Preparing Lift for Initial Startup

To transport the columns to a location in the repair facility for setup requires that the lifts be
moved. To easily move the columns, raise and lower the trolley handle in a pumping motion 3­5 times until the inner lower column edge is lifted from the floor. You can now maneuver the
lifts to any location by pulling the trolley handle to the desired location. Once you have moved
the lifts into position squeeze the release lever to lower the column to the floor. The lifts will
not operate unless the columns are lowered.

Installing the column covers: Inside the parts carton are four (4) column covers that should be
fitted and bolted to the open column tops using the provided bolts, washers and lock washers.

Adding hydraulic oil: To open the column main door, move the trolley handle to the extreme
right position to prevent the door from hitting the handle when opened. Use the 6 mm allen
wrench and remove the 3 door bolts on the left side of the column and open the main lift
cabinet. The hydraulic power unit tank will have a red plastic plug in the top opening and black
breather plug on the bottom outer edge of the tank. Remove both items and put the red plug
in the bottom hole. (The tank does not have a drain hole) Use a clean funnel and add new
hydraulic oil (AW-32) to the tank and fill to approx. 2” from the top of the tank fill hole. The
approx. amount of oil per column is shown below:

 ML-4030BC 13 Quarts / 12.3 Liters
 ML-6045BC 13 Quarts / 12.3 Liters
 ML-4034BC 15 Quarts / 14.3 Liters
 ML-6051BC 15 Quarts / 14.3 Liters

Install the black breather cap in the top of the tank. Close cabinet door and secure with the top
and bottom bolts. The center bolt secures the battery charger bay door and does not need to
be re-installed. (If the battery charger door tends to stay open,

then loosely re-install the bolt by hand to secure the door thereby making future battery
charging procedures faster)

Note: The hydraulic system was tested during manufacturing. Each hydraulic cylinder and the
power unit tank was filled and cycled to test for leaks and for performance. During this
process the hydraulic cylinders were bleed to remove any air. The hydraulic oil was removed
from the tank after testing. Because residual oil at the bottom of the tank and inside the
cylinder remain, additional hydraulic system bleeding is not necessary.

Battery charging: The LCD display panel will advise you if the batteries need to be charged.
To charge the batteries open the battery charger access door on the left side of the column by

8

removing the bolt and then pull outward on the black knob and fully open the door. A battery
charger is built in to each column. Plug the battery charger electrical cord into a 110 volt
grounded electrical outlet. Charge each mobile column lifts using a separate electrical outlet.
Best performance will be obtained by charging all mobile column batteries at the same time.
Each battery charger front panel has a red and green indicator light. When the indicator light
is red means the battery is charging. When the indictor light is green means the battery is fully
charged.

When the lifts are new, charge the batteries for the first time approx. 12-15 hours or until the
battery charger indicator light turns green. Battery charging after 20-30 cycles will typically
take 6-8 hours. When the batteries are fully charged, disconnect the electrical cable and store
in the charger bay. Close the access door and loosely secure the door with the bolt.

Please note the safety information below:

An extension cord should not be used unless absolutely

necessary. Use of improper

extension
cords could result in a risk of fire or electric shock. If extension cords must be used, make
sure the following safety precautions are observed.

 That the pins of plug of the extension cord are the same

number, size and shape of those of the

plug on the battery

charger.



That the extension cord is properly wired and in good

electrical condition.



That the wire in

the

extension cord is proper size as recommend below.

Minimum

recommended wire size for various length

extension cords used with each battery charger:

Length

16 Gauge

14 Gauge

12 Gauge

 Do not operate the battery charger with a damaged cord or plug.
 Do not operate the battery charger if it has received a sharp blow, been dropped or

otherwise damaged in any way.

 Do not disassemble the charger. Incorrect reassembly may result in a risk of electric

shock or fire.

 To reduce the risk of electric shock, unplug the charger from outlet before attempting any

maintenance or cleaning. Disconnecting the leads will not reduce this risk.

 To reduce the risk of shock or spark, never touch the ring terminals together while the

charger is plugged into an outlet or extension cord.

 External connections to the battery charger shall comply with all local, state, and federal

regulations.
