MAINTENANCE
* KESLA crane maintenance tasks do not require any special tools that have not been supplied
with the machine. Thus, the crane operator him/herself can perform almost all of the maintenance
tasks.
* The valves' pressure values should not be changed without the permission of the manufacturer
due to the hydraulic circuit values. The valve adjustments and repairs should be performed by au-
thorized service personnel.
* The crane has been thoroughly tested and adjusted prior to shipping from the factory.
* Do not use a malfunctioning crane, but repair even the smallest flaws and defects before they
cause major damage ((see the daily inspection of the crane).
* For easy maintenance, we have established a maintenance schedule for periodic inspections and
maintenance procedures, and the operational interference table for fault localization.
*The persons responsible for crane operation and maintenance need to be aware of these things.
By following the maintenance instructions and by keeping in mind the absolute purity in the
hydraulic installations, the crane works reliably and unnecessary interference is avoided.

DAILY INSPECTIONS
* Check the hydraulic oil and the rotating device's oil level and top up if necessary.
* Lubricate the crane if necessary (see maintenance measures).
* Visually inspect the crane's mounting screws, shaft mounts, hoses and any possible leaks.
* Ensure the management and operation of the safety equipment by running the functions to their
maximum and repair any defects immediately
* Make sure that the STOP- switch is working.
8.3.1 Hydraulic hoses and pipes
- Check that the hydraulic hoses do not have abrasions or bruises that may cause hose rupture.
- Check the hydraulic fittings and pipes for warps or cracks that can cause a sudden breakdown.
- The protections of hoses and movements in the various positions of the loader are checked.
8.3.2
Load-bearing steel structures and welding seams
- Review of steel structures and welding seams after the trial run, that there are no tears, cracks, or
other permanent dangerous deformation.
- Check that no inappropriate alteration or repair welding has been made in the structures.
8.3.3 Shaft locks
- Check that the shaft locks are not loose or disconnected.
