When stopped or parked always apply the parking device. This is especially im-
portant when parking on a slope. On very steep inclines or if the ATV is carring
a cargo, the wheels should be blocked using rocks or bricks.
Uphill
Keep your body weight forward towards the top of the hill. Keep your feet on
the footpegs and shift into low gear then accelerate and when necessary, change
gear quickly as you climb. Do not over-speed since this may cause the front of
the vehicle to lift from the ground and fall back on you. If the hill is too steep
and you cannot proceed or the vehicle begins to roll backwards, apply the brake,
being careful not to slide. Dismount then use the "U" turn or "K" turn (while
walking back, next to the vehicle on the up hill side and with a hand on the brake
lever, slowly back the rear of the vehicle toward the top of the hill then drive
downhill). Always walk or dismount on the upside of the slope while keeping
clear of the vehicle and its rotating wheels. Do not try to hold on to the vehicle if
it begins to topple. Stay clear. Do not ride over the crest of the hill at high speed.
Obstacles, including sharp drop-offs, may exist.
