Section 3 - MAINTENANCE
! | WARNING | ! |
DO NOT attempt any maintenance, adjustments or service with engine and blade running. STOP engine and blade. Remove key. Disconnect spark plug wire and secure away from spark plug. Engine and compo- nents are HOT. Avoid serious burns, allow sufficient time for all components to cool. Wear heavy leather gloves when handling or working around cutting blades. Blades are extremely sharp and can cause severe injury.
3.2.4. CHECK MOWER BLADE
1.Disconnect spark plug wire and secure end away from plug.
2.Tilt mower up on its rear wheels for access to the blade cap screw. See Figure 3.2.
IMPORTANT: DO NOT tip machine with carburetor or spark plug down. Oil from crankcase will saturate the air fil- ter and cause the engine to be hard to start or not start at all. If contamination does occur, the air filter will have to be replaced.
3.Check torque of blade retaining cap screw. Recommended torque should be 30 to 40 ft. lbs. See Figure 3.2.
4.Check blade for sharpness, wear and damage. Refer to Section “BLADE WEAR LIMITS”.
3.2.5.CHECK ENGINE to TRANSMISSION DRIVE BELT
1. Visually check belt for cracking, fraying, severed or belt strands exposed. Replace belt before operating mower. Refer to Section ”BELT SERVICE” for replace- ment instructions.
