Danger! - Caution with leaking lines
Effect: Danger to life, injuries or damage to the machine.
•When searching for leaks, use suitable aids, always use suitable tools and wear
protective goggles to avoid the risk of injury!
•Escaping high-pressure fluids can penetrate the skin and cause serious injury. Therefore,
you must depressurise the system before disconnecting lines.
•Hydraulic oil escaping from a small opening can barely be seen. Because of this you
should use a piece of cardboard or something similar when searching for leaks. Protect
your hands and body.
•If any fluid penetrates the skin, it must be removed immediately by a doctor who is
familiar with this kind of injury; serious infections could otherwise result. Physicians who
are not familiar with this area should consult appropriate information from a competent
medical source.
•Check the hydraulic hose lines at regular intervals and replace them if damaged or worn!
The replacement lines must comply with the requirements of the device manufacturer.
•Ensure that all line connections are tight before the pressure in the system builds up
again.
•Repair work on the hydraulic system must only be performed by authorised KRONE
professional workshops.

Before placing the machine in winter storage, clean the outside thoroughly. If you use a highpressure cleaner to do this Do not keep a stream of water directed at bearing points. After
cleaning is completed, lubricate all lubrication points. Do not wipe off any grease that comes out
of bearing points. The hardened grease will provide additional protection against moisture.
Check all movable components such as deflector rollers, joints, tension rollers, etc. to make
certain they move easily. If necessary remove, clean, grease and remount. If necessary, replace
with new parts.
Use only original KRONE replacement parts.
Disassemble the PTO shaft. Lubricate the inner tubes and the guard tube with grease. Grease
the lubrication points on the cross joint and grease the bearing rings of the guard tube.
Repair places with damaged paint and preserve all bare metal places thoroughly with rust
protection agent.
Park the machine in a dry location, but not in the vicinity of artificial fertilisers or livestock
buildings. Repair places with damaged paint and preserve all bare metal places thoroughly with
rust protection agent.
The machine should only be placed on blocks with a suitable vehicle lifting device. Make
certain that the machine is stable and safe when it is on blocks.
To provide relief for the tyres, set the machine on blocks. Protect the tyres against external
influences such as oil, grease, direct sunlight , etc.
Perform the necessary repair tasks during the time immediately after the harvest season. Draw
up a list of all replacement parts you will need. This will make it easier for your KRONE dealer to
process your orders and you will be certain that your machine will be ready for use at the
beginning of the next season.
