Backlapping
The reels may stall while backlapping and
could restart suddenly. Contact with the
reels during backlapping will cause personal
injury.
• Never place hands or feet in the reel area
while the engine is running.
• Never attempt to turn the reels by
hand or foot or touch the reels while
backlapping.
• Never change engine speed while
backlapping. Only backlap at idle speed.
• Stop the engine and move the desired
reel speed selector knob(s) one position
closer to "13."
Note: When backlapping, the front units all
operate together, and the rear units operate
together.
