OPERATION
CAUTION
Operate both steering wheel and ground speed lever
slowly while becoming familiar with the machine.
Remember that steering is more sensitive when
speed-range control is in road speed position. Avoid
the common tendency of new Operators to oversteer.
8. If more tractive (lugging) power is required (for
example, when driving up a ramp, up a hill, or up out
of a ditch):
a. Move the GSL (E) closer to NEUTRAL.
b. Switch speed-range control (B) to
L
(low range).
9. Once the lugging condition no longer exists:
a. Set GSL (E) to
NOT MORE THAN HALF
maximum
forward speed.
b. Move speed-range control (B) to
H
(high-range).
Steering is more sensitive in this speed range.

Driving in Reverse in Engine-Forward Mode
WARNING
Back up slowly. Steering is opposite to normal when
reversing. Hold steering wheel at the bottom and turn
wheel in direction you want the rear (cab-forward) of
the machine to travel.
1. Move speed-range switch (A) to
L
(low-range position).
2. Move throttle lever (B) to a mid-range position.
NOTE:
Reversing in low speed range and at reduced
engine speed is recommended since steering will
be less sensitive than at higher speed settings.
