2. SAFETY REGULATIONS
2.1 GENERAL SAFETY REGULATIONS
• Do not use defective hydraulic top links.
Check for damage before use.
• Only original components from
Walterscheid GmbH should be used.
• Welding and/or straightening work on the
hydraulic top link is forbidden.
• Damaged components should not be used.
ATTENTION
Before putting the hydraulic top link into ser-
vice, make sure that freedom of movement
in all directions is ensured in every possible
installation position.
(See Figs. B1, B2, B3, B4 and B5).
2.2 ADDITIONAL SAFETY REGULATIONS
FOR THE HYDRAULIC TOP LINK WITH
SHOCK ABSORBER (DS)
• Work on the shock absorption system of the
hydraulic top link with shock absorber should
only be carried out by trained specialist staff
from specialist agricultural and construction
machinery workshops. (See instructions:
ATAS18_01, Part-No.: 113635)
ATTENTION
• Oil may leak out during the filling process!
ATTENTION
• Due to the shock absorber, the piston rod can
move up to 30 mm within the hydraulic top
link during operation.
ATTENTION
• The shock absorption function will no longer
operate when the top link is fully extended.
2.3 ADDITIONAL FUNCTION “HYDRAULIC
FLOAT SETTING” FOR THE HYDRAULIC TOP
LINK WITH SHOCK ABSORBER (DS)
ATTENTION
If the “float setting” function is activated, the
top link can move freely in a set path. This in-
cludes both directions in which the hydraulic
top link operates(extend / shorten).
SETTING UP AND ACTIVATING THE FLOAT
SETTING
The float setting is activated by extending
the hydraulic top link when the working
equipment is raised.
The float setting can also be set up with
equipment attached. Establish the working
length using the positioning guide (in normal
work process with lowered equipment) which
is located on the side of the top link. Raise the
equipment attached using the lifting gear,
then fully or partially retract the top link back
to the working length established before-
hand. This enables you to set the desired
width of the float area which ranges from the
shortest position approached to the working
position of the hydraulic top link.
DEACTIVATING FLOAT SETTING
To deactivate the float setting, simply extend
the top link again. The top link can of course
be retracted or extended further as you wish.
IMPORTANT:
The attached equipment must be placed on
the ground by the lifting gear for this
process.
