Other connections between implement and
tractor must be handled independently of the
coupling and uncoupling processes.
For eyebolts:
• Remove the implement-side bolt on the
eyebolt.
• Place the top link in the support clip.
• Retract the piston rod fully by actuating the
control valve, in order to avoid dirtying/da
maging the piston rod.
Other connections between implement and
tractor must be handled independently of the
coupling and uncoupling processes.
Normally, the components supplied are main
tenancefree. However, we recommend the
following checks and/or maintenance work
from time to time:
• Make sure that the hydraulic system is not
leaking.
Hydraulic oil must not get into the ground.
• Clean all moving parts as required and apply
commercial grease to ensure their smooth
operation; excess grease must be disposed of
according to the applicable regulations; make
sure that it does not get into the ground.
Relevant information can be obtained from
your dealer and/or lubricant supplier.
The following additionally applies to hydraulic
top links with hook:
• Check the securing components of the top
link hook and the swivelling eyebolt, e.g.
spring, locking bolt, retaining rings; replace
them, if necessary.
Malfunctions of the locking system are
usually attributable to dirt accumulation.
• Only trained and instructed persons may
work with/on the hydraulic top link. The
operator must clearly define the responsibili
ties of these persons regarding operation,
servicing and maintenance.
5. Maintenance notes
5.1 general maintenance notes
Touching the piston rod during retraction is
strictly forbidden – risk of trapping!
ATTenTiOn
Any person to be trained may only work with/
on the hydraulic top link under the supervision
of an experienced person.
The operator may only perform the work
described in these Operating Instructions.
Only specialist workshops may perform any
work or repairs on the hydraulic top link that
require special expertise. Specialist workshops
have the qualified personnel and suitable aids
(tools) necessary to perform this work correctly
and safely.
This applies to all work not described in these
Operating Instructions.
Immediately replace any components that are
not in perfect condition.
When doing so, use only original parts from the
manufacturer, or spare parts, wear parts and
consumables approved by the manufacturer.
When using spare parts and wear parts from
third-party manufacturers, or non-approved
consumables, it cannot be guaranteed that
they are designed and manufactured to with-
stand the relevant stresses and comply with
safety requirements. The manufacturer accepts
no liability for damage or losses caused by the
use of non-approved spare parts, wear parts
and consumables, or repairs performed by non-
approved persons.
5. Special maintenance notes for the hydraulic
top link with shock absorber
Ensure the screw plug on the piston rod is
firmly positioned.
The gas pressure should be checked by a speci-
alist workshop at least 1x per year.
