Section 4 - REPAIR & ADJUSTMENTS

WARNING

DO NOT attempt any adjustments, maintenance or service with the engine or blade running. STOP blade. STOP engine. 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. Wear heavy leather gloves when handling or working around cutting blades. Blades are extremely sharp and can cause severe injury.

4.2WHEEL DRIVE CONTROL ADJUSTMENT IMPORTANT: There should always be some slack in the wheel drive control cable when the wheel drive control is released.

The Wheel Drive Control requires periodic adjustment to maintain proper belt tension on the transmission poly-v belt. Verify proper tension by checking the extension of the spring located at the end of the wheel drive control cable.

1.Stop engine and allow sufficient time to cool.

2.Engage wheel drive control. The length of the spring located at the end of the drive control cable should increase between ½” and ¾”. See Figure 4.4.

If the spring does not increase between ½” and ¾”, adjustment is required.

3.To adjust the amount the spring extends (belt tension) slide the black spring cover up to expose the spring. Unhook the cable eyelet from the spring.

4.Grip the hook on the spring and turn either Clockwise or Counter-clockwise. Clockwise increases spring extension and belt tension Counter-clockwise decreases spring extension and belt tension.

5.Attach the control cable eyelet to the spring and recheck spring extension. If spring extension is correct slide the spring cover down over the spring. Start engine, and with blade control released (blade stopped) verify the wheel drive functions properly. If spring extension is not correct turn spring Clockwise / Counter-clockwise.

6.If drive problems persist after adjusting the spring extension Refer to Section “TROUBLESHOOTING” of this manual or contact your local Snapper Dealer for assistance.
