8. Apply lapping compound with long-handled brush
supplied with machine (Fig. 23). Never use a short
handled brush.
9. If reel to be backlapped turns too slowly, or erratically,
stop engine and turn H.O.C. knob one position toward
"A". Repeat steps 5 – 8. Position "P" will provide the
slowest speed for backlapping. Position "A" will provide
the fastest speed for backlapping. New motors will
generally backlap at position "P", but with time, the
setting may need to be moved closer to "A" to compen­
sate for motor wear.
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 – 8.
11. Repeat procedure for all cutting units to be back­
lapped.
12. When backlapping operation has been completed,
return the backlap switch to OFF, lower seat and tighten
both locking bolts securely. Wash all lapping compound
off cutting units. Do cutting unit reel to bedknife adjust­
ment as necessary.
IMPORTANT: If the backlap switch is not returned to
OFF position after backlapping, the cutting units
will not raise or function properly.
IMPORTANT: If the cutting units are removed for
backlapping (such as when bedknives are replaced)
the reel speed sensors must be removed from the
left front and left rear cutting units. Before backlap ­
ping, install a 3/8" capscrew in the left end of the
reel shaft to drive the reel when backlapping. DO
NOT attempt to use the capscrew which attaches
the magnet to drive the reel for backlapping – this
capscrew must be tightened to a maximum torque
of 5 ft-lb to avoid damage to the magnet.
NOTE: For a better cutting edge, run a file across the
front face of the bedknife when the lapping operation is
completed. This will remove any burrs or rough edges
that may have built up on the cutting edge.
