1. Cautions
1.1 Do not modify, or maintain electronic control system without permission;
1.2 Working load on each column should be no more than rated load of 7.5 tons;
1.3 Make sure there is no sundry on column tracking surface before lifting, or the slide blocks may
be damaged;
1.4 Load type of electric motor is S2, with 15 minutes working time;
1.5 Maxima Heavy Duty Column Lift is equipped with double safety system of mechanical lock and
hydraulic check valve. Before working under elevated vehicle, please make sure there is no
abnormality with all connections;
1.6 Please use high quality hydraulic oil according to Chart 1. Fill in at least 12 L oil into oil tank.

vehicle lift. Driven by hydraulic cylinder in each column, the lifting arm goes up and down easily
and smoothly. High accuracy balancing system ensures the cylinders working synchronously.
Unique design fits heavy duty vehicle assembling and repair shop.
ML4030B/ML604B applies to vehicles within 30/45 tons for purposes of assembly, repair, and
maintenance, oil-changing, washing and other possible services.
Unique Synchronization System:
To ensure a smooth lift up/down cycle, even when the load on lift is unequally distributed;
Human Engineering:
Operation is available at all columns. One set includes one main column and 3 slave columns
(ML4030B)/ 5slave columns (ML6045B);
Safety measures
Double safety system, mechanical lock and hydraulic check valve ensures safe operation;
Diagnosing Trouble Functions:
It will stop immediately if there is any problem.
3. Technical Parameter
MAXIMA Wireless Heavy Duty Column Lift is designed & manufactured strictly under European
Standard EN1493:1998.
Ground requirements: compression strength ≥15MPa; Gradient ≤1:200; within the area of the
columns, the level difference must not be more than 10 mm;
Keep the equipment away from combustible or explosive materials.

5.1. Control switches
5.1.1. Power switch
When this switch is at “OFF”, the lift is powered off and no operation is available; when this
switch is at “ON”, the lift is powered on and prepared for operation. Switch to “CHARGE” to
charge the battery.
5.1.2. “POWER” Light
When the power switch is at “ON”, it is shining.
5.1.3. “FAULT”light
When the carriages overrun the limit synchronous value of the each column or the heavy duty
connector of the cables become loose, it shines. And all the other switches do not work.
5.1.4. Mode selection knob
Turn the knob to “SINGLE”, columns can be operated to go up and down individually;
Turn the knob to “PAIR”or “ALL”, two columns/four columns/six columns can be operated to
go up and down together;
Note:
1. Before turning Mode Selection knob, please power off the lift and wait for 20s first;
2. “PAIR”mode can be used when four/six columns are communicating well. A and B columns
become a pair, same with C and D columns. Please be careful to operate this function. “ALL”
mode is used when there are four/six columns connecting together; “SINGLE” mode can be
used to operate one column individually;
3. In case of an emergency, turn downward the change-over switch (Fig. 7) in control box, so
that the equipment can be operated without communication line;

We introduce four columns operate process here; operation of two columns is the same way.
7.1. Raise
7.1.1. After testing successfully, move the four holding fork arms to their very positions. The
contacting range must equal with the width of the tires. The right position of each column is
shown as Fig.11.
Fig. 11
7.1.2. Connect all columns with communication cable according to Fig. 12, turn the Mode
Selection knob to PAIR or ALL mode, and power on main column and all slave columns. LCD
screen will show work interface after successful connection.
Fig. 12
7.1.3. Press and hold the “UP”button, when the height reaches 10cm, the column stops, and
the beep rings for 2 seconds; please loose the button, and ensure all carriages are lies tightly
against the tires. Then continue lifting up the columns.
7.2. Lower
7.2.1. Press and hold the “DOWN”button to lower the vehicle. When the carriage reaches
30cm, the column stops automatically, and the beep rings, please do not put your feet under
the carriage to avoid any hurts.
7.2.2. After lowering the vehicle to the ground, move the lift away from it and then drive the
vehicle away.
NOTE:
1. When there is vehicle on the system, make sure 4 wheels of vehicle are on same level, and
choose ALL mode;
2. Don't lift any vehicle before hydraulic trolley unloads the press!
