MAINTENANCE
1. Lubricate the axes and moving parts at regular intervals (E).
2. The elements of the press should be kept clean and protected from aggressive conditions at all times.
3. Always use original spare parts.
4. Check the oil level of the pump with the piston of the cylinder fully retracted and refi ll as required in accordance with the
volume indicated in the table.
reach the tank. The cover is threaded on its upper part.
5. IMPORTANT: An excess of oil may affect the operation of the hydraulic unit.
6. Only use hydraulic oil,
3 at 50ºC.
EXTREMELY IMPORTANT: Never use brake fl uid.
7. A frequent inspection should examine:
• Wear on the piston, cylinder, pump, accessories or incorrect connections.
• Oil leaks, signs of corrosion.
• Damage to the structure, accessories, table and supports, lost screws or plug-ins.
TO CHANGE THE MANOMETER
Remove the metal cover, position the manometer, making sure that the O-ring seal which is inside
the manometer casing remains at the bottom upon installation. Secure the manometer according to
the fi gure (H), without applying excessive force.
REPAIR
1. Both the maintenance and repair of these presses should be carried out by qualifi ed personnel, who as a result of their
training and experience are familiar with the hydraulic systems used.
2. Both the repair kit, which exclusively contains the o-rings and seals of the jack, and the spare parts sets must be
orderedusing the reference assigned in the table.
3. TO PURGE THE HYDRAULIC CIRCUIT:
- Open the release valve by turning it to the left.
- As follows, pump the hydraulic unit several times.
- Lastly, close the release valve by turning it completely to the right.
PROBLEM
1. The piston does not lift
2. Piston does not lift totally
3. Piston lifts very slowly
4. Cylinder looses pressure while holding the load
5. Oil leakage
6. Piston does not retract fully
