Pilot On/Off
The pilot solenoid is an ON/OFF valve controlled by the ECM. It is controlled by the Implement Lockout Switch in the cab or from one of the Failure Mode Effects Analysis (FMEA) modes.Float Valve
The Float valve solenoid is activated during a lower kickout and it remains active for 80ms after the lever moves out of detent during a kickout or until the kickout is manually deactivated. Float control is provided to assist the operator in maintaining a level grade while dozing or during cleanup operation. The lift arm will operate as if the lift cylinder was disconnected from the linkage. The bucket will float over any obstacles that are underneath the bucket.Raise Solenoid
The solenoid controls the pilot control actuator for the raise end of the main control spool.Lower Solenoid
The solenoid controls the pilot control actuator for the lift lower end of the main control spool.Dump Solenoid
The solenoid controls the pilot control actuator for the tilt dump end of the main control spool. The pilot control actuator directs the pilot oil from the dump end of the main control spool to the hydraulic tank.Rack Solenoid
When the rack kickout control is activated the loader tilt linkage stops at a previously set rack kickout position without operator intervention.
