Revision C
c. Set ground speed range switch (D) to H for road
speed [0 - 23 mph (37 km/h)]. CDM will display
ROAD GEAR at (E), and an alarm will briefly
sound.
d. Slowly push throttle (F) to full forward (operating
speed). CDM should display 2270 - 2330 RPM
(M150), 2250 - 2300 RPM (M200) at (G).
CAUTION
Check again to be sure all bystanders have
cleared the area.
e. Slowly move the GSL (A) forward to desired
speed which will be displayed at (H).
CAUTION
Operate both steering wheel and ground
speed lever slowly for familiarization.
Remember that steering is more sensitive
when speed-range control is in Road Speed
Position. Avoid the common tendency of new
operators to over-steer.
f. When more tractive (lugging) power is required,
for example, driving up a ramp, up a hill, or up out
of a ditch:
1. Move the GSL (A) closer to neutral.
2. Switch speed-range control (D) to L (low
range).
g. Once condition as per f. no longer exists:
1. Set GSL to not more than half maximum
forward speed.
2. Move speed-range control (D) to H (high
range). Steering is more sensitive in this
speed range.
6.3.6.3.1 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.
a. Move speed-range switch (D) to L.
b. Move throttle lever (F) 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.
CAUTION
Check again to be sure all bystanders have
cleared the area.
c. Move the GSL (A) rearward to desired speed.
d. Steer as shown below.
