1Safety
1.1 Introduction
Thoroughly read this manual before operating the lift and comply with the instructions.
Always display the manual in a conspicuous location.
Personal injury and property damage incurred due to non-compliance with these safety

1.2 Intended Use
This single column vehicle lift is classified as movable model. Movable single column
vehicle lift is specially useful for indoor. It is the special equipments for lifting vehicles, such
as cars, which park on ground, to a certain height for maintenance. It is forbidding to park
vehicles. Observe the rated load capacity and load distribution of the lift.
1.3 Safety Instructions for Commissioning
The lift may be installed and commissioned by authorized service personnel only.
The standard lift version may not be installed and commissioned in the vicinity of
explosives or flammable liquids, outdoors or in moist rooms (e.g. car wash).
1.4 Safety Instructions for Operation
Read the operating manual.
Lift operation by authorized personnel over 18 years only.
Always keep the lift and lift area clean and free of tools, parts, debris etc.
Once the disk adapters contact the lift points, check arm restraints for engagement.
After raising the vehicle briefly, stop and check the disk adapters for secure contact.
Always lift the vehicle using all four adapters.
Make sure the vehicle doors are closed during raising and lowering cycles.
Closely watch the vehicle and the lift during raising and lowering cycles.
Do not allow anyone to stay in lift area during raising and lowering cycles.
Do not allow anyone on lift or inside raised vehicle.
Only use the lift for its intended purpose.
Comply with the applicable accident prevention regulations.
Do not overload the lift. The rated load capacity is indicated on the lift nameplate.
Only use the vehicle manufacturer’s recommended lift points.
After positioning the vehicle apply the parking brake.

3
Use caution when removing or installing heavy components (center-of-gravity
displacement).
The main switch serves as emergency switch. In case of emergency turn to OFF
position.
Protect all parts of the electrical equipment from humidity and moisture.
Protect the lift against unauthorized usage by padlocking the main switch.
1.5 Safety Instructions for Servicing
Maintenance or repair work by authorized service personnel only.
Turn off and padlock the main switch before doing any maintenance, or repair work.
Work on pulse generators or proximity switches by authorized service personnel only.
Work on the electrical equipment by certified electricians only.
Ensure that ecologically harmful substances are disposed of only in accordance with
the appropriate regulations.
Do not use high pressure/steam jet cleaners or caustic cleaning agents.
Risk of damage!
Do not replace or override the safety devices.
1.6 Safety Features
1.6.1 Hold-to-run Type Control
The operator is required to hold the controls in the engaged position to raise or lower the lift.
1.6.2 Equalizing System
The lift is provided with distributing and connecting flow valve to ensure level movement of
both carriages.
1.6.3 Pipe Break Valve
The hydraulic cylinders are equipped with pipe break valves. They respond in case of rapid
pressure drop (line break) to prevent sudden lowering movements.
1.6.4 Pressure Relief Valve
A pressure relief valve is used to limit the hydraulic working pressure to a maximum of
200bar.
1.7 Disposal of used oil
Used oil, which is removed from the power unit and the plant during an oil change, must
be treated as a polluting product, in accordance with the legal prescriptions of the country
in which the lift is installed.
1.8 Machine demolition
The machine must be demolished by authorized technicians, just like for assembling. The
metallic parts can be scrapped as iron. In any case, all the materials deriving from the

4
demolition must be disposed of in accordance with the current standards of the country in
which the rack is installed. Finally, it should be recalled that for tax purposes, demolition
must be documented; submitting claims and documents according to the current laws in
the country in which the rack is installed at the time the machine is demolished.

4. Packing, transport and storage
Only skilled personnel who are familiar with the lift and this manual shall be allowed
to carry out packing, lifting, handling, transport and unpacking operations.
4.1 Packing
90% components were pre-assembled before shipment, and packed with blister packing in
steel frame. Arms, adapters and rubber pads were put in the lift. Power unit was packed in
carton box separately, power unit stand was packed and fixed on above the lifts.
4.2 Lifting and handling
When loading/unloading or transporting the equipment to the site, be sure to use suitable

6
loading (e.g. cranes, trucks) and hoisting means. Be sure also to hoist and transport the
components securely so that they cannot drop, taking into consideration the package’s size,
weight and centre of gravity and it’s fragile parts.
4.3 Storage and stacking of packages
Packages must be stored in a covered place, out of direct sunlight and in low humidity, at a
temperature between -10°C and +40°C.
4.4 Delivery and check of packages

distance when opening straps) and parts of the lift (be careful the objects do not drop from
the package when opening).
5 Installation
5.1Working Site
The user should prepare the working site for the lift before its arrival
5.1.1 Power Source The working site must be equipped with certain power. Install safety
distribution box with a 4-hole socket around the operation position.
5.1.2Ground The lift must be placed on flat and hard ground, which is made of cement or
bricks, with the load at the position of vertical post of 3t/m2.
5.1.3 Working Area There should be ＞about 1,000mm space around the vehicle
lifted, and the net height indoor is about 3600mm.
5.2 Installation
Because of the limitation of transportation, lift shall be disassembled to pack. The users
should assemble the lift according to the following figure:
Assemble movable single column lift
Overall assembly as follows:

6. Operation instruction
6.1 Operation Rules for mechanism System
6.1.1 The movable single column lift is provided with separate traveling mechanism.
Shake the hauling handle of the steering rear wheel forwards and backwards to
make the vertical column off the ground, then you can push or pull the lift. On arriving
the working site, press the valve handle to retract the wheel, then the vertical column
lands on the ground steadily.
6.1.2 The lift must only be pushed into the vehicle if in line with it. Insert the pallet under
the vehicle beam and the pallet must be in line with the beam.
6.1.3 Retract the rear wheel of vertical post to land the vertical post steadily before the lift
lifts load, and make sure there is no foreign article such as hand tools, bolts, screw
caps, small stones. No lifting during moving!
6.2 Operating Steps for Electrical Control System
New machine is operated for commissioning without load before its first use. The
electrical box is provided with “0-1”main power switch, which should be turned off
after the machine use finished.
6. 3 Operation Flow:

8
1) Vehicle stops in the service position with engine off
2) Turn the handle for hydraulic movable wheel to lift the vertical post base a bit
3) Push the lift into the underside of vehicle
4) Make sure there is no foreign articles under the base and the ground is level
5) Grasp the valve handle to make the base lowered to ground
6) Align 4 pallets on the lifting arm respectively to the supported positions on the vehicle
