Section 4 - ADJUSTMENTS & REPAIR

WARNING

DO NOT attempt any adjustments, maintenance or service with the engine or blade running. STOP blade. STOP engine. Set brake. Remove key. Remove spark plug wire from spark plug and secure wire away from spark plug. Engine and components can be extremely hot. Avoid burns by allowing engine and components sufficient time to cool.

4.2.9.MOWER DECK ADJUSTMENT (LEVELNESS) 1. Side-To-Side (42”Decks)

Before making deck leveling adjustments, check the tire pressure. Check tires and add or release air as needed to bring pressure to 12 P.S.I. in front and 12 P.S.I. in rear tires. If tires are properly inflated and mowing is still uneven, adjust side-to-side deck levelness as follows:

a. Place SCRAMBLER on a smooth level surface.

b. Turn engine off and remove key, remove spark plug wire(s) from spark plug(s) and secure wire(s) away from plug(s).

c. Place a piece of angle iron, pipe, or similar object under center of deck at the rear.

d. Remove rear hanger chains and allow center, rear of deck to rest on angle iron.

e. Measure the distance from blade tips to floor. If the measurement is within 1/8” from side-to-side, the deck levelness is satisfactory. If the difference from side-to-side is greater than 1/8”, continue to the Step “f” for adjustment. See Figure 4.6.
