2. With engine operating at mid throttle and hydraulic system warmed up, press bottom of row units raise/lower button (B) to lower all units to preset height.

3. CAUTION: If you or others become entangled in a unit, serious injury or death can result. Make sure that multifunction control handle remains in neutral position and stand clear of units during testing. Keep away from areas which can pinch or crush as units move up and down.

   Have an assistant lift one of the unit height sensing shoes (C) until units are fully raised, then release shoe. Verify that units return to previous height.

4. NOTE: Set header height so units are positioned no lower than necessary to pick cotton. For low hanging bolls or lodged and tangled limbs, position plant guides (D) or wear plate (E) so they just touch the top of the beds (just skim the surface, not plow).

   To adjust header height: Press left- or right-hand height adjust buttons (F) and rotate selection dial (G) clockwise to raise operating height of corresponding row units or counterclockwise to lower operating height. Observe setpoint (H) on armrest display unit.

5. Recheck unit tilt adjustment. (See ADJUSTING ROW UNIT TILT in Row Units section.)

6. Set response rate. (See HEADER HEIGHT CONTROL RESPONSE RATE ADJUSTMENT in this section.)
