Transmission control
Start moving the machine with the machine in first
gear or in second gear. To upshift, rotate the
transmission control to the next highest gear. It is not
necessary to release the accelerator control. To
downshift, rotate the transmission control to the next
lowest gear. Do not skip gears when you downshift.
Continue to shift through the gears in this way as the
conditions are required. To prevent engine overspeed,
do not downshift if the engine speed is high. Refer to
the topic "Transmission Control" in Operation and
Maintenance Manual, "Operator Controls" for additional
information.
Control the speed of the machine in order to suit
conditions. Make an allowance for surface conditions,
weather conditions and load.
NOTICE
Damage to the transmission could occur if the machine
is allowed to coast in neutral. Damage to the
transmission could also occur if a change of direction is
selected at an excessive speed. Do not allow the
machine to coast. Only select a transmission direction
change if the machine is in first gear and moving at less
than 4 km/h (2.5 mph).
Note: These machines are not equipped with
speedometers. Before you change the direction of the
machine from forward to reverse or from reverse to
forward stop the machine completely.
Select the correct gear before you travel downhill.
Select the necessary travel speed before you start
downhill. Do not change gears while you are going
downhill. When you go downhill, use the same speed
that would be used to go uphill. Do not allow the
engine to overspeed when you go downhill. Use the
service brake to prevent engine overspeed when you
go downhill. Select a lower gear before you go down the
same hill again.
When you are travelling uphill, select a lower gear
when the engine speed starts to fall. Drive the
machine in the gear that will allow the required speed to
be maintained. Do not allow the torque converter to
slip and do not allow the engine to lug.
Hydraulic Quick Coupler
Your machine may be equipped with a hydraulic quick
coupler.
Illustrations in the following procedure show a carriage
which is equipped with forks. The procedure is
applicable to all work tools with the same types of
mounting points.
Installation Procedure
Illustration 94 g01060075
1. Move the red portion of the switch for the quick
coupler downward and press the top of the switch.
Hold the top of the switch until the quick coupler
pins are fully disengaged. Release the switch.
2. Lower and extend the boom approximately 2 m
(6.6 ft) so that the quick coupler can be seen from
the cab. Position the quick coupler in line with the
carriage.

3. Tilt the quick coupler forward until the quick
coupler tubes (1) are below the level of hooks (2).
