EWB00091
POTENTIAL HAZARD
Changing from four-wheel drive to four-
wheel-drive differential gear lock or vice-ver-
sa while the ATV is moving.
WARNING
WHAT CAN HAPPEN
The ATV handles differently in four-wheel
drive than in differential gear lock in some
circumstances. Changing from four-wheel
drive to differential gear lock or vice-versa
while moving may cause the ATV to handle
differently unexpectedly. This could distract
the operator and increase the risk of losing
control and causing an accident.
HOW TO AVOID THE HAZARD
Always stop the ATV before changing from
four-wheel drive to four-wheel-drive differen-
tial gear lock or vice-versa.
EWB00101
POTENTIAL HAZARD
Riding too fast while the ATV is in four-
wheel-drive differential gear lock.
WHAT CAN HAPPEN
All wheels turn at the same speed when the
differential gear is locked, so it takes more
effort to turn the ATV. The effort needed to
turn increases with the riding speed. You
may lose control and have an accident if you
cannot make a sharp enough turn for the
speed you are traveling.
