7.6 Connecting the static multiple-disk parking brake

Your planetary gearbox is/may be equipped with a static multiple-disk parking brake
to serve as parking brake.
Risk caused by the failure of the static multiple-disk parking brake!
The static multiple-disk parking brake is a safety device of the planetary gearbox.
The improper connection of the static multiple-disk parking brake or its use as
dynamic brake (using the multiple-disk parking brake for braking the vehicle) may
result in its destruction!
Operate the static multiple-disk parking brake only after a complete stop of the

vehicle.
Always observe that the integrated multiple-disk parking brake that is only

intended as parking brake must be inspected and maintained by our service
after dynamic braking.
Ensure maximum cleanliness when connecting the multiple-disk parking brake.

Make sure that neither dirt nor foreign substances penetrate in the brake

release connection.
Ensure that the brake release connection is carefully sealed.

Assemble hydraulic lines and hoses without mechanical stress.

Use e.g. copper sealing rings according to DIN 7603 as sealing means.

Make sure that no dynamic pressure occurs in the brake line.

Only use pressure fluid based on mineral oil for operating the static multiple-

disk parking brake.
Avoid contamination caused by unclean pressure fluids, rubbed-off parts or

residual dirt from system components.
Observe by all means the specifications for release pressure and maximum

brake release pressure. Also make sure that the minimum release pressure is
observed so that the multiple-disk parking brake can be completely released.
Observe by all means the specifications on the gear unit dimensioned drawing

when connecting the static multiple-disk parking brake. These can be found in
appendix D "Technical data / Drawings" of the material number-specific
operating instructions.
