          3. INSPECTION/ADJUSTMENT                                   ATV 50


 Inspect the wheel.
 Replace if damage or bends
 Always balance the wheel when a tire or
 wheel has been changed or replaced.
 · Never attempt even small repairs to the
     wheel.
   · Ride conservatively after installing a
     tire to allow it to seat itself properly on
     the rim.




 DRIVE CHAIN SLACK
 ADJUSTMENT
 Before checking and/or adjusting, rotate the
 rear wheels several revolutions and check
 slack at several points to find the tightest
 point. Check and/or adjust the chain slack
 with the rear wheels in this "tightest"
 position.
 Too little of chain slack will overload the
    engine and other vital parts; keep the
    slack within the specified limits.

 Place the machine on a level place.
 Wheels should be on the ground without
    the rider on it.

 Check drive chain slack.
 Adjust if out of specification.
 Drive chain slack: 10-20 mm (0.4 ­ 0.8 in)



                                                   Bolts

 Adjust drive chain slack:
 Elevate the rear wheels by placing a suitable
 stand under the rear of frame.
 Support the machine securely so there is
    no danger of it falling over.

 Loosen four bolts attaching rear axle hub.
