4.3.5. BLADE BRAKE ADJUSTMENT
The SNAPPER YARD CRUISER is equipped with
an electric clutch/brake that should stop blade
rotation in 5 seconds or less after being turned off.
If blades continue to rotate longer than 5 seconds,
adjustment or replacement is required. When
properly adjusted, a .010" to .012" feeler gauge will
fit thru the three inspection slots located on the side
of the clutch as shown. See Figure 4.5. Excessive
clearance can adversely affect the function of the
clutch and produce blade stop times over 5
seconds. To adjust, turn the three adjusting nuts
clockwise to reduce clearance. The clearance at
each of the three slots must be set the same.
