Section 4 - REPAIR & ADJUSTMENTS

WARNING

DO NOT attempt any maintenance, adjustments or service with engine and blade running. STOP engine and blade. Disconnect spark plug wire and secure away from spark plug. Engine and components 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.

4.2WHEEL DRIVE CONTROL ADJUSTMENT (Engine To Transmission Deck Belt)

The wheel drive control requires periodic adjustment to maintain proper engine to transmission drive belt tension. The adjustment is located on the right handle and requires no tools. See Figure 4.5.

IMPORTANT: DO NOT operate engine when inspecting or adjusting the drive belt.

1.Visually check engine drive belt for cracking, fraying, severed or belt strands exposed. Replace belt before operating mower.

2.To check for proper drive belt tension. STOP engine. Shift ground speed control to 1st and engage the wheel drive control. See Figure 4.4.

3.With the wheel drive control engaged, pull the mower handles, moving the mower rearward. Observe the rear wheels.

4.If the rear wheels slide on the surface (no rotation) the belt is properly tensioned and the control does not require adjustment.

5.If the rear wheels rotate, increase belt tension by rotating the thumb screw COUNTER-CLOCKWISE.

6.Turn thumb screw one turn at a time and recheck tension (repeating steps 3-5).

7.When proper belt tension has been set, operate

machine and verify proper wheel drive control function.

IMPORTANT: DO NOT over-tighten wheel drive control. DO NOT operate if control or drive does not function properly. Contact your local SNAPPER Dealer for assistance.

IMPORTANT: If machine creeps forward after wheel drive control is released the cable is too tight and must be readjusted to eliminate all forward movement. Machine must not have any forward movement when wheel drive control is disengaged. If the wheel drive control fails to return quickly to the “OFF” position when released, check for a broken, binding, or kinked cable.
