Using SCV Control Levers
 CAUTION:
Prevent possible personal injury. Hydraulic hoses are reversed at the couplers if cylinder is extending when it should be retracting. Switch hoses at the coupler.
Cover (A) can be moved to cover SCV levers (I -IV) when not in use.
SCV control levers (I-V) have six positions:
-
Neutral
-Lever returns to center position when released except in float position
-
Extend
(rearward between Neutral and Extend Detent)-variable flow to extend cylinder, proportional to lever movement; shuts off when returned to center position
-
Extend Detent
(rearward to "click" position)-timed flow to extend cylinder, based on detent time setting and at a rate set by flow rate control (See ADJUSTING TIMED DETENT and ADJUSTING SELECTIVE CONTROL VALVE FLOW RATE, in this Section) Lever returns to neutral when released
-
Retract
(forward between Neutral and Retract Detent)-variable flow to retract cylinder, proportional to lever movement; shuts off when returned to center position
-
Retract Detent
(forward to "click" position)-timed flow to retract cylinder, based on detent time setting and at a rate set by flow rate control. (See ADJUSTING TIMED DETENT and ADJUSTING SELECTIVE CONTROL VALVE FLOW RATE, in this Section.) Lever returns to neutral when released
-
Float
(fully forward and down into locked position)-valve is open to sump to allow cylinder to extend or retract to allow implement to follow ground contour; must be pulled up and out of locked position to disengage
NOTE:
To relieve hydraulic pressure in implement, move SCV control lever to float position, while engine is running.
