Armrest Controls—Six Position SCV Levers

A - Hitch

B - SCV I

C - SCV II

D - SCV III

E - SCV IV

F - SCV V

G - Cover

H - SCV Lever (In Neutral)

I - Extend Range

J - Retract Range

K - Extend Detent Position

L - Retract Detent Position

M - Float

CAUTION: To avoid personal injury, ensure hoses are not reversed. If hoses are reversed, cylinder will extend when it should retract.

NOTE: Float can also be used to allow hydraulic motors to coast when shutting down an implement. Neutral and Float are the only positions that SCV lever will remain without being held.

• Neutral (H)—Lever returns to center position when released except in float position.
• Extend (rearward between Neutral and Detent Position Extend )—Variable flow to extend cylinder, proportional to lever movement and flow settings; shuts off when released to center position.
• Extend Detent Position (K) (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 SCV FLOW RATE in this section). Lever returns to neutral when released.
• Retract (forward between Neutral and Detent Position Retract)—Variable flow to retract cylinder, proportional to lever movement; shuts off when released.
• Retract Detent Position (L) (forward to "click" position)—Timed flow to retract cylinder, based on detent time setting and rate set by flow rate control, (See ADJUSTING TIMED DETENT and ADJUSTING SCV FLOW RATE ). Lever returns to neutral when released.
• Float (M) (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 an implement, move SCV control lever to float position, while engine is running.

Push SCV lever cover (G) forward when SCV is not in use.
