Figure 5. Example of a Manual Hydraulic Pump
The parking brake is a SAHR - Spring Applied Hydraulic Re-
leased brake. In case of a breakdown or a malfunction of the
hydraulic system, the parking brake can be released by using a
manual high pressure hydraulic pump that must be connect-

NOTE: The minimum release pressure is 435 psi. The maxi-
mum release pressure is 653 psi.
