Be careful when backlapping the reel because contact with the reel
or other moving parts can result in personal injury.
7. To make a cutting unit adjustment while backlapping, turn reels OFF, shut
off engine and wait for all machine and cutting unit motion to completely
stop. Then, after cutting unit adjustments have been completed, repeat steps
4 through 6.
8. When the backlap operation is completed, shut off engine and rotate
directional valve lever fully (90º from the backlap position) to the F (forward)
position. Also, rotate the flow control valve knob to correct mowing position.
9. Wash all lapping compound from the cutting units.
