Connect hydraulic lines
NOTICE
Risk of damage to the hydraulic system
When
connecting hydraulic lines, always connect the drain line first. When disconnecting the hydraul-
ic lines, always disconnect the drain line last.
Introducing even the smallest dirt particles or oil impurities while fitting attachments to the front or
rear can cause damage to the hydraulic system.
► Attachment mounted: store the protective caps in the driver's cab's tool compartment.
► Attachment not mounted: cover the quick-connect couplings with clean protective caps.
