WHEELDRIVEBELT

ADJUSTMENT

The wheel drive belt requires an adjustment if loss of drive belt ten-

sion (slippage) occurs. This is most noticeable when more trac-

tion is required (such as going up slopes).

ToTestWheel Traction

1. Park machine on a paved (con-

crete, etc.) surface with front edge up against a sturdy wall, fence, etc.

2.Put Gear Select Lever in No. 1 setting.

IMPORTANT: Do not park against a painted or sided wall. Testing the wheel drive system requires machine to be forcibly pushed against wall. Damage to paint or siding could result.

3.With engine running, and ma- chine placed firmly up against

wall, hold down Operator Pres- ence Control and fully engage wheel drive by squeezing Wheel Drive Control until it contacts handlebar.

4.Wheels should slip on paved surface. If they do not, an adjust- ment is required.
