WARNING
• This procedure MUST be performed as
specified and only by properly trained
service personnel.
Adjusting the speed control screw out (increasing
length) will reduce the mow speed. Adjusting the
speed control screw in (shortening length) will
increase mow speed.
Determine which direction to adjust the mow speed
screw. Loosen the locking nut and adjust speed
control screw, snug up the locking nut and run the
time test again, repeat as necessary. When correct
mow speed has been obtained, tighten the locking
nut (See Fig. 19).
