DESCRIPTION
2.1 DESCRIPTION (Ref. Figure 1)
This air/hydraulic rolling jack has been designed to be placed on a lift for
maintenance of vehicles. This chapter describes the unit’s principal elements,
allowing the user to be familiar with the rolling jack. As shown in figure 1,
the bridge jack is composed of the base unit (1) and an air-hydraulic pedal
pump (2) which can be placed on the holder (3). Raising or lowering of the
jack is carried out by operating the pump as shown in chapter 4.

INSTALLATION
3.1 HYDRAULIC LINE CONNECTION (ref. figure 3)
- Connect hydraulic hose to the fittings;
- Tighten thoroughly;
- Connect the air-hydraulic pump to an external air supply (not included with jack);
- Check the pneumatic control operations for proper performance.
For extended service and proper operation, it is recommended that external air supply include a water separator, lubricator and pressure reducer.

OPERATION
Never operate the lift except for intended purpose.
Never exceed the rated lifting capacity.
Never raise the jack more than the rated height.
4.1 CONTROLS
Controls for operating the jack are:
Figure 4 CONTROLS OF BRIDGE JACK
LIFTING SIDE OF PEDAL (1)
- When pressed, the hydraulic fluid is delivered from the oil reservoir of the pump into the jack cylinder to raise the jack.
LOWERING SIDE OF PEDAL (2)
- When pressed, the hydraulic fluid is released from the jack cylinder into the oil reservoir of the pump to lower the jack under the weight loaded. The lowering speed can be controlled by the pressing force.
SAFETY LOCK RELEASE HANDLE (3)
➢ Flip the safety lock release handle up off the safety to lower.
Always ensure that the mechanical safety is engaged before any attempt is made to work on or near the vehicle.
JACK LIFTING ARM (4)
Jack operation can be summarized in three steps:
4.2 LIFTING
Never raise the jack beam beyond rated height. The manufacturer will not be
responsible for the damage because of the incorrect operation.
- Check and keep the lift rail channel clean of debris and any object that may hinder the movement of the bridge jack.
- Lower the jack fully by depressing the lowering side of the pedal.
- Adjust the width of the jack lifting arms so that the rubber pads will contact the lifting points of the vehicle recommended by the vehicle manufacturer.
- Raise the jack by depressing the lifting side of the pedal. Keep an eye on the jack when the rubber pads contact the vehicle to ensure proper contact. Re-adjust the width of the jack lifting arms if necessary.
4.3 STANDING
- Stop raising the jack just as vehicle is raised off the lift runways. Confirm the vehicle is stable and seated properly before lifting the vehicle to the desired height.
- After the vehicle is raised to the desired height, lower the jack to the nearest safety lock position.
4.4 LOWERING
- Be sure the safety area is free of people and obstructions.
- Raise the jack high enough to clear off the mechanical safety lock and then flip the safety release handle up off the lock.
- Lower the jack fully by continuing to press the lowering side of the pedal.
MAINTENANCE
Only trained personnel who know how the jack works, should be allowed to
service the jack.
To properly service the lifting jack, the following should be carried out:
- use only genuine spare parts as well as equipment suitable for the work required;
- follow the scheduled maintenance and check periods shown in the manual;
- discover the reason for possible failures such as too much noise, overheating, oil blow-by, etc.
Refer to documents supplied by the dealer to carry out maintenance:
- functional drawing of the electric and hydraulic equipment
- exploded views with all data necessary for spare parts ordering
- list of possible faults and relevant solutions.
5.1 ORDINARY MAINTENANCE
The jack must be properly cleaned at least once a month. Use self-cleaning
clothes.
The use of water or inflammable liquid is strictly forbidden
Be sure the rod of the hydraulic cylinder is always clean and not damaged since this may result in leakage from seals and possible malfunctions.
5.2 PERIODIC MAINTENANCE
Every 3 months| Hydraulic system| ▪ check oil level in the pump reservoir;
refill with oil, if needed;
▪ check the system for oil leakage.
---|---|---
Every 6 months| Oil| ▪ Check oil for contamination or ageing.
Contaminated oil is the main reason for failure of valves and shorter life of
the pump
Every 12 months| General check| ▪ verify that all components and mechanisms
are not damaged
TROUBLESHOOTING
A list of possible troubles and solutions is given below:
| T ROUBLE: | POSSIBLE CAUSE: | SOLUTION: |
|---|---|---|
| The jack does not raise | The oil in the pump reservoir is not sufficient. | Add |
hydraulic oil
