WHEEL DRIVE BELT

ADJUSTMENT

The wheel drive belt requires an adjust- ment if loss of drive belt tension (slip- page) occurs. This is most noticeable when more traction is required (such as going up slopes).

To Test Wheel Traction:

1.Park machine on a paved (concrete, 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 machine placed firmly up against wall, hold down Operator Presence Control and fully en-

gage wheel drive by squeezing Wheel Drive Control until it contacts handlebar.

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

To Adjust Wheel Drive Belt:

1.Stop engine, wait for all parts to stop moving, and disconnect spark plug wire.

2.Remove cotter pin (A, Figure 5-12A) from upper end of Wheel Drive Control rod. Slide rod out of lever assembly.

3.Loosen jam nut (D, Figure 5-12).

4.Thread rod (E, Figure 5-12) one or

two turns clockwise for more tension or counterclockwise for less tension.

5.Insert rod back into hole in Wheel Drive Control lever and install cotter pin. Bend ends of cotter pin to secure.

6.Retest wheel traction. Repeat adjust- ment procedure, if necessary. Most comfortable operation will be obtained when the adjustment allows the lever to just make contact with the handgrip as sufficient wheel traction is achieved. When adjustment is complete, tighten jam nut (D) firmly against block (B).

WHEEL BRAKE ADJUSTMENT

This adjustment may be required if the machine does not hold on a hill with the Operator Presence Control disengaged, or if the brake drags with the Operator Presence Control engaged and the trans- mission in neutral.

1.Stop engine, wait for all parts to stop moving, and disconnect spark plug wire.

2.Disengage (release) the Operator Presence Control (M, Figure 5-13).
