DO NOT attempt any adjustments, maintenance, service or repairs with the engine running. Stop engine. Stop blade. Engage parking brake. Remove key.

	Route belt around stationary idler.
3.	Remove spring that is connected to idler pulley.
Loosen nut and bolt that secures idler pulley to idler
arm. Route belt between belt guide and idler pulley.

4.3.5. BLADE BRAKE ADJUSTMENT

The SNAPPER SCRAMBLER 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.

4.	Route belt onto spindle pulley. Make sure belt is
inside spindle pulley belt guide.
5.	Reinstall idler pulley spring. See Figure 4.4.
NOTE: The idler belt guide should be positioned so
the locator tab fits into the corresponding hole
found on the idler arm. See Figure 4.4. Tighten bolt
securely.
6.	Reinstall footrest/floor pan assembly.
