2. Overview of the machine
2.1 Product Introduction
The floor plate lift is composed of posts, carriages, lifting arms, hydraulic cylinders, power unit and floor plate, etc. The lift is operated
by an electric motor controlling a hydraulic system, which delivers the hydraulic fluid to cylinders inside the columns for lifting two
carriages. The safety teeth block will bite with safety plate in the posts automatically. Therefore, the lift will not lower when hydraulic
system trouble happens.

weeks of receipt, and missing parts are noticed when installing the lift, will Jema Autolifte as well as our distributors not be
responsible for missing parts and will charge for the purchase of spare parts.
3.1.3 Floor specifications
The lift should be fixed on a smooth and solid concrete ground with its strength more than 3000psi, tolerance of flatness less
than 5mm and minimum thickness of 200mm. In addition, newly built concrete ground must undergo more than 28days’ cure
and reinforcement.
3.2 Precautions during installation
3.2.1 Make sure that the columns are vertical to the floor.
3.2.2 When installing the hydraulic oil hoses on both piston and engine please make sure they are installed properly to
prevent oil leaks.
3.2.3 All bolts on the lift must be tightened when the lift is assembled as they may have shaken themselves loose during
transport.
3.2.4 Placing no vehicle on the lift before it is tested after installation.
3.3 Installation
Step 1: Remove the packing of the lift and remove the cardboard box with accessories, and the floor plate.
Step 2: Remove the lift arms and the control box located the columns
Step 3: Support the columns and remove the bolts that hold the columns in each end of the transport cage.
NOTE: Be careful if the columns falls down will the lift or people around the lift be injury
Step 4: Rise the columns in vertical position with a lifting device lifting.

Step 5: Decide the installation position of the columns, erect the main and assistant post. Pay attention that the
width between posts is 2830mm.
1. It must also be decided on which side the main column should be placed. (Normally left in the access direction is normal)
2. When the position is selected, use now lime ribbon to place the main column and the assisting column in line to each other.
3. Before work is continued, double check that the columns are the correct position in the room and the columns are properly placed
to each other.
Step 6: Rise the columns, main post first and then the assistant post
Before drilling holes for fixing the columns, place the complete floor plate in between the columns in order to
ensure that the distance is correct.

1、Drill each anchor hole in the concrete using a rotary hammer drill. To assure full holding power, do not
ream the hole or allow drill to wobble
2、After drilling, remove dust thoroughly from each hole and make certain that the column remains aligned
with the chalk line during this process.
3、Position the main column at the designated chalk locations and follow the same procedures step 1, 2 to position the assistant
column.
Step 7: Installation and adjustment of the calibration wire
1. Rise and lock each carriage approximately 800 mm bottom position.
2. Make sure the safety locks in each column is activated before mounting the calibration wires.
3. Both carriages for the main column and the Assistant column must be the same height when installing the calibration wires.
4. With the carriages at the same height from the floor, install the calibration wires as shown below.
5. After the calibration wires are installed, each wire adjusted to have a uniform stance.
(It is IMPORTANT the calibration wires are not to tight since that will give unexpected load on the wire wheel and bushings)
6. Lubricate the wire with Chain spray or grease.
Step 8: Install the power unit on the main column.
1. Install the power unit with the 8mm bolts which is with the lift.
(The bolts should NOT be tightend before the hydraulic oil hoses and been installed)

Step 11: Mount the control box (Remember to fasten all terminal blocks and wires as they may shake loose during transport)
1. Connect the power unit with the control box as the wiring diagram
2. Connect the limit switch on the main Column. (NB. Note the misalignment of the limited switch within the column!)
Step 12: Install the oil hose cover of the both columns.
Step 13: Install the lifting arms
Mount the lift arms with the supplied mandrels, it is important respect of the weight distribution on the lift that the long arms are
ALWAYS placed at the rear of the vehicle and therefore will be mounted as shown on the picture below. Check and adjust the arm
lock to go in the grip when the lift is raised so that the arms cannot move away under the vehicle when lifting.

Step 14: Add the hydraulic oil
The volume of the oil tank is 12L ， To insure the lift in a normal work condition, the oil should be over 90% of the oil tank volume;
Use AW 32# in winter/46# in summer or other good quality garage hydraulic oil.
Step 15: When all the steps from 1 to 14 are double-checked, connect the lift to power and try to press the "UP"
button (Do not place any vehicle in this step)
Step 16: Install the chain protection and the door-opening protection
Trin 17: Install the Cover plate on the floor plate.
When everything has been installed and the lift is tested, then install the foot protection, plastic tops and high adaptors.

6. Maintenance
Maintaining the lift is incredibly important to make sure the lift is safe to work with and the lift span is extended.
If the lift is not being maintained according to the requirements by a professional technical company will Jema Autolifte
not be responsible for any accidents or errors that might occur with the lift.
THE FOLLOWING PARTS ARE NEEDED TO BE LUBRICATED.
IMPORTANT: Check the lifting platforms are in perfect condition before using the lift!
6.1. DAILY PRE-OPERATION CHECK
The user should perform daily check. Daily check of safety latch system is very important –the discovery of device failure
before needed could save you from expensive property damage, lost production time, serious personal injury, even death.
Check safety lock audibly and visually while in operation.
Check safety latch for free movement and full engagement with rack.
Check hydraulic connections and hoses for leakage.
Check chain connections for bends, cracks and looseness.
Check cables connections for bends, cracks and looseness.
Check for frayed cables in both raised and lowered position.
Check snap rings at each roller and sheave.
Check bolts, nut and screws. Tighten if needed.
Check wiring and switches for damage.
Keep base plate free of dirt, grease or any other corrosive substances.
 Check floor for stress cracks near anchor bolts.
