Tip-over hazard. Do not adjust the
lift and/or drive speed higher than
specified in this procedure. Setting
drive speed greater than
specifications could cause the
machine to tip over resulting in
death or serious injury.
On machines with software
revision B1 or lower, high torque
drive speeds in forward and
reverse are simultaneously
adjusted, resulting in both
directions of travel operating at the
same speed.
On machines with software
revision C0 or higher, the high
torque forward drive speed and
the high torque reverse drive
speed may be adjusted
independent of one another. See
5-2, How to Determine the
