MAINTENANCE
Important:
Both the maintenance and repair of this crane may only be carried out by qualied and authorized personnel, who as a result of their training
and experience are familiar with the hydraulic systems used in these
devices.
1. Clean and lubricate the axes of the moving parts of the crane at regular intervals. The crane should be kept clean and protected from aggressive
conditions at all times.
2. Only original spare parts should be used.
3. Withdraw the crane from service if it is suspected that it has been subjected to abnormal loads or has suffered any type of knock until the problem
has been resolved.
4. If the oil level needs to be checked or relled, dismantle the hydraulic unit and with the piston fully retracted, remove the ller plug and drain its
contents into a container. With the hydraulic in a horizontal position, proceed to introduce the necessary volume for each model as indicated in these
instructions. Avoid the entrance of any dirt with the new oil.
Important: An excess of oil over the volume required may affect the operation of the crane.
5. Only use hydraulic oil, type ISO 22. Extremely important: Never use brake uid.
6. When the crane is not in use, it should be fully retracted in the lowest position so as to minimize piston corrosion. It is
recommendable to apply an anti-corrosion product to the main piston and to the pump.
7. Store the crane in a dry, clean place, out of the reach of children.
8. At the end of the useful life of the crane, drain off the oil and hand it over to an authorised agent and dispose of the remaining parts in
accordance with local regulations.
9. Both the repair kit, which exclusively contains the retainers and joints and the spare part sets must be ordered using the reference assigned in the
table.
