OPERATION AND MAINTENANCE INSTRUCTIONS
This lifting device is specially developed to lift motor cars and we strongly recommend not to lift any other
equipment with this automotive car lift.
DESCRIPTION
The lift is an electro-hydraulic 4 post surface-mounted lift with capacity ranging from 3 to 5.2 t.
The lift consists of 2 pairs of posts connected with cross beams. The 2 platforms rest on the cross beams.
Furthermore, the lift is equipped with a wheel-free device; which consists of 2 cross beams placed on the outer
sides of the main cross beams and a pair of rails fitted to the wheel-free cross beams.
Platforms and cross beams for the main lift are raised and lowered bymeans of cables and a hydraulic cylinder
placed under one platform. The cables are attached to a yoke on the piston rod and run via cable pulleys to the four
post tops with an incorporated adjustment device.
The hydraulic pump unit and control box are placed on the front right post.
The lift is operated by means of pushbuttons showing the UP, DOWN and PARKING functions with indicators.
Furthermore, the control unit is fitted with a rotary switch for activation/deactivation of the wheel-free device.
Sound level measured at the control unit at a height of 1.6 m: max. 74 dB(A).

INSTALLATION
In order to come up to your expectations now and in the future the lift must be installed in strict accordance with the
installation instructions and maintained according to our recommendations.
Contact your distributor for the name and address of the nearest authorized service shop.
FITTER INSTRUCTIONS
Install the lift in strict accordance with the original installation instructions which are included in each delivery.
The lift must be installed on solid foundation: concrete with minimum load capacity5500 N/m² and surface spot load
under posts 350 kN/m²; torque for expansion bolts attaching the posts: 25 Nּm.
There should be sufficient light for work on and under the lift. For the lift a lighting set is available as an optional
extra comprising four impact-proof, water-tight fluorescent tubes including cable (state model number).
Avoid installing the lift in rooms with danger of explosion.
WARNING: Person transportation is forbidden.
OPERATION
The lift should only be operated bytrained personnel !
Approch
Before driving the vehicle on to the lift, check that platforms are parallel (the
same indicator position at both ends.
Raising
Push UP-button (motor starts): raise lift to a bit above required working
height.
Parking
Let go of UP-button and push PARK-button ➔ until platforms rest on all 4
ratchets.
Lowering
Check that no person or obstruction is under platforms. Push UP-button
shortly (to release the 4 ratchets) and then press DOWN-button . The lift
then lowers until the lift reaches automatic anti-toe trap device and the
lowering stops. Let go of DOWN-button and re-activate it after approx. 1
sec., the lowering continues until the lift reaches bottom position or until
pushbutton is not pressed any more.
NOTE: Always park lift (press ➔ button) before starting to work under it.
Operation Wheel-free:
When pushing UP-button , both platforms and wheel-free device are raised simultaneously. At the height wanted,
the rotaryswitch is activated and the wheel-free device parked. When pushing DOWN-button the platforms will
be lowered. When the job is finished, the platforms are raised till they reach the wheel-free device and the vehicle is
set off on the platforms. Deactivate the rotaryswitch; check that no persons or obstructions are under the platforms
and push UP-button shortly (to release the 4 ratchets). Push DOWN-button and the lift lowers until it reaches
the automatic anti-toe trap device and then stops. Let go of DOWN button; after app. 1 sec. reactivate it and the
lowering will continue until the lift reaches bottom position.

Adjust the platforms to the wheel track of the vehicle.
Place the vehicle centrally on the platforms compared
to the wheel track.
It is not allowed to operate the main lift while the vehicle is raised on one or two scissor jacks and it is not
fastened.
WARRANTY:
This lift is guaranteed for one year, covering faults due to manufacturing or material defects, provided that the
installation, operation and maintenance instructions are observed.
IMPORTANT ! Product liability accepted only if solely original spare parts have been used.
MAINTENANCE
Oil level check Check regularly the oil level in the reservoir under the pump. Fill up as necessary, correct oil
level is in the middle of the oil glass alternatively of dip stick.
Oil change First oil change after one year of operation, thereafter every 6 years.
Oil contents Approx. 8 l (for pump unit with built-on electric motor)
= 6.5 l (for pump unit with plunged electric motor)
Oil type See page 8
Lubrication and maintenance
Check and lubricate it at least once a month as follows:
Where
What
When
Axles for cable pulleys (with
grease nipples)
Grease
Once a month
Cables and rollers *)
Lubricating oil
Once a month
*) Check cables for wear
CLEANING
Cleaning of 4-post surface mounted lifts to prevent corrosion damages.
Corrosive fluids as brake fluid, oil, fuel or other solvents must be wiped off immediately, otherwise damage will
occur to the coating.
Special attention must be paid to the corrosive effect of salt in fall and winter periods.
The cleansing agents must not have any abrasive effect, nor contain solvents.
The lift must be cleaned at least once a week.
The lift must be cleaned with a non-corrosive cleansing agent.

Bradbury Equipment does not accept any claim concerning the paint peeling off or corrosion damages caused by
missing or insufficient cleaning or maintenance.
Repair of damages:
Repair of damages on the coating must be carried out immediately in order to minimize the extent of the repair.
The damages will typically be:
1. Damages which do not affect the metal surface but affects the coating itself
2. Damages going down into the metal surface.
Repairs:
Contact Bradbury Equipment for guidance.
Order number for repair paint is to be seen in the spare parts list and contains basic cleanser, primer and paint
together with instructions for repair of paint damages.
Please state RAL number of paint.

ADJUSTMENT OF CABLES
Steel cables will stretch depending on the operational load and therefore require adjustment as follows:
a. Load the lift with approximately 2500 kg (5500 lbs).
b. Switch off air supply. Adjust wires to make the 4 ratchets engage simultineously when UP-button is activated.
c. Raise lift to top position. Check distance from underside of ratchet to underside of hole in ratchet rail; this
distance must be min. 20 mm.
d. Lower the lift to bottom position and check that the platforms rest against their stops. If not, adjustment of
cables is necessary.
CONTROL OF CABLES
Check cables for wear at the monthlylubrication intervals and replace as necessary (see below paragraph
concerning scrapping).
NOTE: The monthly lubrication with thin penetrating oil reduces cable wear and prolongs cable life appreciably.
GENERAL: At least once a year the cables must be checked-up by an authorized engineer.
Contact your distributor for the name and address of the nearest authorized service shop.
If documentation on cables and/or cable construction is required, please state the stamp on the cable lock. On
this request, copy of original certificate will be forwarded.
SCRAPPING OF CABLES
The steel cable must be discarded when:
•the cable is worn-down on more than10% wear of its nominal diameter
•an individual wire is worn more than 1/3 of the wire diameter
•the number of wire ruptures on a twisting length exceeds 10 on any spot of the cable
•the cable has a kink (pulled-out loop)
•the cable is flattened or cornered, even if there is no wire ruptures
•the wires in a strand are burst
•the cable is damaged by corrosion, even if there is no wire ruptures
•the cable has been damaged through chemical influence.

from spare parts list included in delivery) as well as lift serial number and year of production (to be seen from serial
number plate).
EMERGENCY LOWERING (In case of power cut-out) (not single phase lifts)
Turn mains on 0-position.
Bymeans of a jack raise one corner of the cross beam 3-4 mm. Pull out the ratchet and block it with a piece of
band. Repeat this in the 3 other corners.

TROUBLE SHOOTING CHART
In case of breakdown check the following points:
1. Electricity cut
2. Main fuses
3. Motor starter
4. Electric motor
5. Cable fracture
6. Obstruction under lift
If these points are found in order but the lift is still not working, the safety system has probablybeen activated, and
the lift must not be started or repaired by unqualified staff. Contact the nearest authorized service shop.
Do not start repairing the lift until the main switch has been cut off.
Do not disconnect the safety system and do not operate the lift after breakdown and prior to repair.
