7.1 MAINTENANCE
1. IMPORTANT: Both the maintenance and repair of the jack may only be performed by
qualified persons, who have sufficient knowledge of the hydraulic systems used in
these devices as a result of their training and experience.
2. Keep the jack clean and lubricate all moving parts at regular intervals, which must be
clean and protected from aggressive conditions at all times.
3. Only original spare parts should be used.
4. Prior to each use, check for bent, broken, cracked or loose parts. Do not use if any
defects are present. If it is suspected that the jack has been subjected to abnormal
loads or has suffered any knocks, withdraw it from service until the problem has been
rectified.
5. If the oil level needs to be checked or refilled, with the piston fully retracted, remove the
filler plug and drain its contents into a container. With the jack in a horizontal position,
proceed to introduce the necessary volume of oil required.
6. Make sure that no dirt enters with the new oil. Ensure the air filter is free from dirt.
7. Following a period of prolonged intensive use, it is recommendable to change the oil in
order to extend the useful life of the jack.
8. IMPORTANT: An excess of oil to the volume required may render the jack inoperative.
9. Only use suitable hydraulic oil. Never use brake fluid.
10. When the jack is not in use, make sure the lifting arm is fully retracted to avoid
corrosion. Apply an anti-corrosion product to the pistons, if appropriate.
11. Keep the jack in a clean, dry place and out of children’s reach. Remove the operating
handle.
12. At the end of the useful life of the jack, drain off the oil and hand it over to an
authorised agent and dispose of the jack in accordance with local regulations.
