Operation Section
transmission control to the next lowest gear. Do not
skip gears when you down shift. 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.
Control the speed of the machine in order to suit
conditions. Make an allowance for surface conditions,
weather conditions and load.
Note: The machine should be in first speed or second
speed when you change the direction of the machine
from forward to reverse or from reverse to forward.
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.
Note: When the torque converter is stalled due to an
excessive load, down shifting will not change the gear
until the service brake has been applied.
Horn (22)
Horn - Push the horn in order to sound the
horn. Use the horn in order to alert personnel.
Also, use the horn in order to signal personnel.
Starting Aid Switch (23)
SLE1-1250
Starting Aid Switch - Switch (23) is a momentary
switch. Push in the left side of switch (23) in order to
activate the air inlet heater.
Refer to Operation and Maintenance Manual, "Engine
Starting" for the correct procedure to start the engine
when the air inlet heater is required.
Auto/Manual Switch (24) (If Equipped)
SLE1350-Up
Auto/Manual Switch - This is a two-position
switch. If your machine is equipped with the
Powersynchro transmission, this switch is an
option on your machine. Push the left side of the switch
in order to select automatic shifting between the gears
of the transmission. The operator will select the
highest speed range and the machine ECM will
automatically shift the transmission between the lowest
gears to the highest gear that has been selected,
based on ground speed of the machine. A lamp inside
the switch will be illuminated. Push the right side of the
switch in order to manually select a specific speed gear.
Directional Turn Signal Control (25)
Directional Turn Signal - Push up on the
switch in order to activate the left turn signal.
Pull down on the switch in order to activate the
right turn signal. The mid-position is the OFF position.
Note: The turn signal only operates when engine start
switch (26) is in the ON position.
Engine Start Switch (26)
Electrical power is supplied to the systems in the cab
when the engine start switch has returned from the
START position to the ON position.
OFF - When you insert the engine start switch
key and when you remove the engine start
switch key, the engine start switch must be in
the OFF position. To disconnect the power to the
electrical circuits in the cab, turn the engine start switch
key to the OFF position. Also, turn the engine start
switch key to the OFF position in order to stop the
engine.
When the key is in the OFF position the following
circuits remain activated:
• Hazard warning
• Interior light
• Parking lights
Turn the engine start switch key clockwise to
the ON position in order to activate all electrical
circuits except the starting motor circuit. Before
the engine will start, transmission control (21) must be
in the NEUTRAL position. To start the engine, turn the
engine start switch key clockwise from the ON position
to the START position. Release the engine start switch
after the engine starts. The engine start switch will
return to the ON position.
Note: If the engine fails to start, return the engine start
switch key to the OFF position. Wait for twenty seconds
before you attempt to start the engine again. This will
allow the monitoring system to reset.
Note: As the machine powers up the machine goes
through a number of self test and system checks. The
hydraulic functions are not available for operation for
four seconds until the self test is completed.
Your machine may be equipped with a security
system. When a security system is installed, only the
correct electronically programmed key will start the
engine.
