If your ATV can't make it up a hill you are
trying to climb:
Turn the ATV around if you still have for-
ward speed. If not, stop, dismount on the
uphill side of the ATV and physically turn
the ATV around. If the ATV starts to slip
backwards DO NOT USE THE REAR BRAKE
- the ATV may tip over on top of you. Dis-
mount the ATV on the uphill side. (See
pages 7-45 ~ 7-53.)
If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards the uphill side of the ATV to main-
tain proper balance. If the ATV starts to tip,
steer down the hill (if there are no obstacles
in your way) to regain balance. If you dis-
cover that the ATV is going to tip over, dis-
mount on the uphill side. (See pages 7-59 ~
7-61.)
