POTENTIAL HAZARD
Changing engine speed while backlapping
may cause reels to stall.
WHAT CAN HAPPEN
Reels may restart. Contact with rotating
reels will cause serious injury.
HOW TO AVOID THE HAZARD
Never place hands or feet in reel area while
engine is running.
Never change engine speed while
backlapping.
Only backlap at idle engine speed.
Never attempt to turn reels by hand or foot
while engine is running.
6. Select either front or rear on the backlap switch
to determine whether front or rear reels will be
backlapped.
7. Move Enable/Disable switch to Enable position.
Move Lower Mow/Lift control forward to start
backlapping operation on designated reels.
8. Apply lapping compound with a long handle
brush (Toro Part No. 29–9100). Never use a
short handled brush (Fig. 18).

9. If reels stall or become erratic while
backlapping, the reel control light will begin to
blink and the reels will turn off. If this occurs,
turn the H.O.C. selection knob one position
closer to "A". Then, toggle the Enable/Disable
switch to the disable position followed by the
enable position. To resume backlapping, move
the Lower Mow/Lift control lever forward.
10. To make an adjustment to the cutting units while
backlapping, turn reels OFF by moving the
Lower Mow/Raise lever rearward; move the
Enable/Disable switch to Disable and turn the
engine OFF. After adjustments have been
completed, repeat steps 5–9.
11. Backlap until the reels can cut paper.
Note: When the cutting unit is adequately
sharpened, a burr will form on the
front edge of the knife. Using a file,
carefully remove the burr without
dulling the cutting edge (Fig. 19).
