speed. The back position gives
maximum torque for rough ter-
rain and climbing grades. The
center position allows the
machine to be driven as quietly as possible.

A three position switch allows the operator to
adjust the automatic self leveling system. This
switch is used to adjust platform level in situa-
tions such as ascending/descending a grade.
3. Horn
A push-type HORN switch supplies electrical
power to an audible warning device when pressed.
