Eaton Fuller® Transmission,
Operating Tips
Refer to the Eaton website for additional information,
www.roadranger.com .
Follow these important operation principles:
•
For all conditions, use the highest gear that is
still low enough to start the vehicle moving with
the engine at or near idle speed, and without
slipping the clutch excessively.
When operating on-highway with no load or
under ideal conditions, use 1st gear to start the
vehicle moving forward.
When operating off-road or under adverse con-
ditions, use LOW gear to start the vehicle mov-
ing forward.
•
Use the clutch brake to stop gear rotation
when shifting into LOW or reverse while the
vehicle is stationary. The clutch brake is actu-
ated by depressing the clutch pedal all the way
to the floor.
•
Partially disengage the clutch to break engine
torque during normal gear shifts.
•
Double-clutch between all upshifts and down-
shifts that require movement of the shift knob.
Splitting of gears does not require movement
of the shift knob.
•
Never push the range-preselection lever down
into low range while operating in high range,
except when downshifting from 5th gear to 4th
gear.
•
Do not shift from high range to low range at
high vehicle speeds.
•
Never make a range shift or a splitter shift
while the vehicle is in reverse.
•
Never move the range-preselection lever with
the transmission in neutral while the vehicle is
moving.
•
Skip ratios while shifting only when operating
conditions permit, depending on the load,
grade, and road speed.
•
Never coast with the transmission in neutral.
Eaton Fuller Splitter and
Range-Shift Transmissions
Combination splitter and range-shift transmissions
allow the choice of two splitter ratios in each gear, as
well as the additional ratios provided by a low range
and a high range.
General Information, Range-Shift
Transmissions
IMPORTANT: Not all ratios are used in each
range, and the shift patterns vary between
transmissions. Read the shift pattern decal on
the dash for the operating instructions for the
transmission installed in your vehicle.
The range-preselection lever selects the low or high
range for each transmission ratio. It is used once
during an upshift sequence and once during a down-
shift sequence.
To operate a range-shift transmission, move the gear
shift lever through all the low-range gear positions
and then pull the range-preselection lever up to
move into the high-range ratios.
IMPORTANT: Always preselect range shifts
when upshifting or downshifting. Preselection
requires that the range lever be moved to the
necessary position before starting to shift. Pre-
selecting range shifts prevents damage to the
transmission and provides for smoother shifts.
General Information, Splitter Control
Depending on the transmission model, some ratios
can be split using the splitter-control button (located
on the side of the gear shift lever).
IMPORTANT: Always preselect splitter shifts.
Preselection requires that the splitter-control
button be moved to the necessary position be-
fore starting to shift. Preselecting splitter shifts
allows for smoother and faster shifting. Com-
plete the shift immediately after preselecting the
split to avoid unnecessary wear on transmission
components.
