service or repairs with the engine running. STOP 
engine. STOP blade. Engage parking brake. Remove 
key. Remove spark plug wire from spark plug and 
secure away from plug. Engine and components are 
HOT. Avoid serious burns, allow all parts to cool 
before working on machine. Fuel Filler Cap and vent 
must be closed securely to prevent fuel spillage.

4.3
  REAR ENGINE RIDER DRIVE COMPONENTS 

Your Snapper rider is equipped with a patented smooth 
start clutch. The clutch should operate smoothly and 
provide ample traction. If problems are experienced, 
contact your Snapper dealer for repair. 

4.3.1.  WHEEL BRAKE ADJUSTMENT 
Test the wheel brake on a dry concrete surface. When 
properly adjusted, the Rear Engine Rider will stop 
within 5 feet from fastest speed.  If stopping distance is 
more than 5 feet, the wheel brake should be adjusted 
as follows: 
1.  Follow WARNING statement found on this page. 
2.  Check fuel level in tank.  If over 3/4 full, remove 
tank. Refer to Section “REMOVING FUEL TANK”.  If 
3/4 or less, proceed to next step.  
3.  Carefully stand Rear Engine Rider on rear bumper.
