Choose the fixing point of the support clip (5)
as shown in Fig.s C2 and C3.
• Attach the release cord (2) on the top link
hook.
• If necessary, the fork head (2) on the tractor
side can be replaced by a fork head with a
different mounting hole.
• Fit high-pressure hoses (R 3/8“ thread –
hoses not included in the Walterscheid scope
of supply, except for hydraulic top links with
eyebolt (A3) on the tractor side) to the top
link and connect them to the tractor; see the
operating instructions for the tractor.
• When using for the first time, after installa-
tion of the high-pressure hoses, the hydraulic
system must be vented by repeated, complete
extension and retraction of the piston rod.
• When putting the top link into service,
ensure sufficient clearance in the tractorside
and implement-side working zones (Figs. b1,
b2, b3, b4 and b5). Do not subject the top
link to bending stress.
• Damage to the piston rod (e.g. due to laying
down incorrectly or dropping) must be avoi-
ded.

• Fix the support clip (5) centrally at an appro
priate point on the tractor rear (provide addi
tional fixing plate/bracket, if necessary) (Figs.
C1, C2).
4. Operation
Coupling the implement with a top link
hook
• Pull and hold the release cord to open the top
link hook
• Set the required top link length by actuating
the control valve.
• Engage the upper ball bush on the implement
by means of the hook
• Release the cord.
Coupling the implement with an eyebolt
• Set the required top link length by actuating
the control valve.
• Engage and secure the eyebolt by means of
the implement-side bolt.
When putting the top link into service, ensure
sufficient clearance in the tractor-side and
implement-side working zones (Figs. b1, b2,
b3, b4 and b5). Do not subject the top link to
bending stress.
• Actuate the control valve to set the top link to
the required service or transport position.
uncoupling
• Lower the implement to the ground.
When using a top link hook, ensure that the
cord can move freely! A taut cord will release
the hook‘s locking mechanism!
The locking mechanism must engage (C3)!

Make sure that the implement stands safely
(see implement instructions)!
• The top link must not be under load.
For top link hooks:
• Use the release cord to release the top link
hook.
• Place the top link in the support clip.
• Retract the piston rod fully by actuating the
control valve, in order to avoid dirtying/dama-
ging the piston rod.
