7 If you are climbing a hill and you find that you have not properly judged your ability to make it to the top, you should turn the ATV around while you still have forward motion (provided you have the room to do so) and go down the hill. If your ATV has stalled or stopped and you believe you can continue up the hill, restart carefully to make sure you do not lift the front wheels which could cause you to lose control. If you are unable to continue up the hill, dismount the ATV on the uphill side. Physically turn the ATV around and then descend the hill. If you start to roll backwards, DO NOT apply either brake abruptly. If you are in "2WD", apply only the front brake. When fully stopped, apply the rear brake as well, and then lock the parking brake. If you are in "4WD" or 4WD-LOCK, because all wheels are interconnected by the drive train, applying either brake will brake all wheels, therefore, avoid sudden application of either the front or rear brake as the wheels on the uphill side could come off the ground. The ATV could easily tip over backwards. Apply both the front and rear brakes gradually. When fully stopped, lock the parking brake and dismount the ATV immediately on the uphill side, or to a side if pointed straight uphill. Turn the 7-16 ATV around and remount, following the procedure described in the Owner's Manual. WARNING! Stalling, rolling backwards or improperly dismounting while climbing a hill could result in ATV overturning. If you cannot control the ATV, dismount immediately on the uphill side. [EWB01802] RIDING DOWNHILL EWB01621 WARNING Going down a hill improperly could cause overturns or loss of control. Always follow proper procedures for going down hills as described in this Owner's Manual.
