Backlapping

DPA Cutting Units: Service and Repairs
TO AVOID PERSONAL INJURY OR DEATH:
• Never place hands or feet in the reel area while the engine is
running. Stay away from the cutting reels when backlapping.
• When backlapping, run engine at idle speed only.
• While backlapping, the reels may stall and then restart.
• Do not attempt to restart reels by hand or foot.
• Do not adjust reels while the engine is running.
• If a reel stalls, stop engine before attempting to clear the reel.
• Reel motors are connected in series: rotating one motor causes
rotation in other motors.
1. Park the machine on a clean and level surface, lower the cutting units
completely to the ground, shut off the engine, set the parking brake, and
remove the key from the key switch.
2. On all cutting units, make initial reel to bedknife adjustments appropriate
for backlapping.
Do not attempt to rotate the directional valve lever on the hydraulic
manifold when the engine or reels are running.
