Transport Operation - Bell B35E 6X6 ADT Operator's Manual

OPERATION
OPERATING INSTRUCTIONS
Gear Pre-Selection
Gear pre-selection means selecting a lower gear to
match driving conditions which the operator
encounters or expects to encounter.
Learning to take advantage of pre-selected shifts
will give the operator better control on slick or icy
surfaces and on downgrades.
Down-shifting to a lower gear increases engine
braking.
The selection of a lower gear often prevents cycling
between that gear and the next higher gear on a
series of up-and-down gradients.
Make adjustments before you encounter an
obstacle:
1. select the correct gear and if necessary lock it
before inclines and declines,
2. select inter-axle diff locks and diff lock switches
before going into soft ground conditions. It may
also be advantageous to lock the transmission,
as a gear change at the wrong time may get
you bogged down.
Gear Hold Function
The Gear Hold switch is used to lock the
transmission in a selected gear and prevent
automatic gear shifting.
The Anti-Shift Cycle controlled by the CCU that
holds the transmission in the lower gear for 12
seconds and engine at 2 120 rpm is overridden
when this switch is activated.
The switch has two positions:
1. OFF; Normal position.
2. ON; Gear hold switched on.
When the switch is OFF, the transmission is in the
normal automatic operating mode and the LED is
OFF.
When the switch is ON, the transmission will hold
the gear that it is in at the time of the switch being
activated. Normal down shifting will occur, but the
transmission will not up shifts to a higher gear until
the switch is switched OFF (except in over speed
conditions).
When the switch is activated, the CDU display
screen will display the gear number that the
transmission will be 'held' in.

Transport Operation

When operating the machine in ideal conditions (e.
g. level graded surfaces) normal driving and gear
selection must be used.
• The machine may be operated at maximum
speed in accordance with the site and road
regulations.
• Always adapt the machine speed to the road and
traffic conditions.
• When driving through a bend do not drive too
fast. The machine's centre of gravity is changed
which may cause the machine to tip or roll if the
road is slippery or cambered the wrong way.
• The machine load must not be allowed to fall off
the machine at any time.
• Do not use the inter-axle differential lock when
operating on smooth graded surfaces.
• Due to the mass of the machine allow for long
braking distances, especially on slippery roads.
Try to roll out ruts on the haul road do not follow the
same route across the ground each time.
Active Suspension (Option)
If the machine is fitted with an active suspension,
the suspension must be lowered before starting the
tie down procedure.
Press A button to display the transport menu. Press
and hold the Enter/Select Botton on the SDC to lo-
wer the suspension.
