FUNCTIONAL TESTS

CONNECTION CHECK-UP
Check carefully to ensure that electrical connections have
been made properly. This can be done by activating the lifting
button momentarily. If the carriage goes up, connections have
been made properly. If the carriage goes down, a wrong connec-
tion has been made. For 3-phase lifts, two phases should be
interchanged in the control box (Fig. 8). For single-phase lifts,
motor connections should be changed as indicated on the corres-
ponding electrical diagram. Care should be taken to operate the
lifting button for only a second, because if connections have not
been made properly, the carriage may descend to its lowest posi-
tion, triggering the safety stop system and locking the lift. If this
happens, carriages must be raised by hand approximately 15 cm.
using a spanner over the nut on the upper part of the driven spin-
dle. The main switch should be disconnected previously.
Manually check for appropriate operation of the arm blocking
devices at different heights.
OPERATING INSTRUCTIONS
Before moving a car into the lift, the arms should be positio-
ned as indicated in Figures 10-A and 10-B and perform one com-
plete service (up-down) to check that (upper and lower) stop
positions are operative and the lift runs smoothly (Fig. 12).
When positioning the car on the electrical lift, ensure that
vehicle weight is equally distributed over the centre of the
columns (Fig. 13-A and 13-B) and that the pads are fitted under
the lifting points recommended by the manufacturer.
Before lifting the vehicle using the lift, make sure the lift arms
have been blocked.
On asymmetrical lifts, it is recommended that the engine side
of the car is supported by the short lifting arms.
When the car is in position, pressing the lifting button will lift
the car until the button is released or the stop switch is activated
when maximum height is reached.
When the lowering button is pressed, the lift descends to any
desired height. When the lowest point is reached, the limit switch
is activated to stop the lift.
SAFETY DEVICE DESCRIPTION AND CHECK-UP
To offset failures in the operating mechanism, the lift is provi-
ded with the following safety systems:
l Safety stop device for obstacles encountered during lowe-
ring (both columns).
l Safety device against wear or breakage of the main nut,
during both lifting and lowering (both columns).
l Safety device against breakage or excessive slackening of
the drive chain.
l Safety device against possible failure of the main control
switch.
l Safety device against breakage of the control cable.
l Safety device against slackening or breakage of any safety
cable.
l The control box can be fitted with a padlock to immobilize
the lift.
All safety systems are checked before the lift leaves the fac-
tory.
VERY IMPORTANT
It is strictly forbidden to eliminate, deregulate or tamper with
safety devices.
M A I N T E N A N C E
Check both columns every three months for the correct sepa-
ration between the main nut and the safety nut (Fig. 12). If the gap
is less than 1.5mm with respect to the measurement marked on
the main nut, it should be replaced.

Check for the correct operation of all safety systems on both
columns every week. When any of these systems is activated,
the lift must not move in either direction.
LUBRICATION AND ROUTINE MAINTENANCE
Before starting the lift, grease the six tracks inside the column
using lithium-based grease with molybdenum bisulphide, consis-
tency NLGI 2, penetration A.S.T.M. 265-295.
Check and grease again after one week if necessary.
SPINDLE BEARINGS: Fig. 14-(1)
Lubricate monthly using calcic base grease group 1 or 2,
penetration A.S.T.M. 265-340.
TRANSMISSION CHAIN: Fig. 14-(2)
Lubricate monthly using lithic base grease with molybdenum
bisulphide, consistency NLGI 2, penetration A.S.T.M. 265-295.
NUT AND SPINDLE TANK: Fig. 14-(3)
Refill with lithic base grease with molybdenum bisulphide,
consistency NLGI 2, penetration A.S.T.M. 265-295.
Check and re-grease if necessary at least once a year.
It is advisable to keep the arm supports lubricated to facilitate
movement.
All other moving parts are permanently lubricated ex-factory.
SUITABILITY FOR USE
Before marketing, all static, dynamic and functional tests
have been carried out at the factory in conformity with Directive
89/392/CEE.
The sound pressure level with ponderation "A" is of 70 dB (A).
