for hydraulic pump priming.
3. Connect the remote starter switch electrical leads to the starter motor
solenoid B+ terminal and positive post of the battery.
4. Engage the remote starter switch and crank the starter for 30 seconds to
prime the hydraulic pumps. Wait for 30 seconds to allow the starter motor and
starter solenoid to cool. Repeat the cranking procedure for the second time.
5. Disconnect the remote starter switch leads from the starter motor solenoid
terminal and positive post of the battery.
Flushing the Hydraulic System
IMPORTANT
Flush the hydraulic system whenever there is a severe component
failure or the system is contaminated (for example, the fluid appears
milky, black, or contains metal particles).
IMPORTANT
If a component failure occurs in the traction circuit; refer to the
Traction Circuit (Closed Loop) Component Failure (page 4–12) for
information regarding the importance of removing contamination
from the traction circuit.
1. Ensure that the hydraulic fluid is at normal operating temperature by
operating the machine for at least 20 minutes.
