Key-Start Switch
The key operated switch actuates the starting motor.
See ‘Starting The Engine’ for the correct operating
procedure.
Road Speed Decal
The decal which is also illustrated on Page IX, shows the
approximate tractor speed in all gear ratios. Accurate road
speed charts are provided at the end of section C.
Charging Indicator
The red warning light on the instrument cluster indicates
that the alternator is not charging the battery and should
extinguish when the engine speed is increased above
idle.
Fuel Gauge
The gauge indicates the level of fuel in the tank and is
only operative with the key-start switch in the ‘ON’
position.
NOTE :
When the key-start switch is turned off the
gauge needle may assume a random position and may
indicates a fuel level greater than the true level. Always
check the fuel level with the key-start switch on.
Air Restriction Warning Light (where fitted)
When this lamp lights up, clean or replace the outer
element of dryair cleaner. If light comes on during tractor
operation when replacement of element is not
immediately possible, just clean the element and reduce
the engine speed so on to prevent the lamp from lighting.
Seven-Terminal Trailer Socket (where fitted)
This socket allows lights, turn signals and other electrical
equipment on a trailer or impliment to be connected.
This is fitted at the rear of driver’s seat.
Always use additional lighting on the mounted implement
if this conceals the turn signals and other lights at the
rear of the tractor.
CONTROL, INSTRUMENTS AND OPERATION
STARTING THE ENGINE
A five-position key-start switch is installed on all the
tractors. For starting in temperatures down to –18
0
C
(0
0
F) the thermostart option may also be installed,
Basically the thermostart consists of an electrically
heated element in the air in taken manifold which, when
operated, ignites a measure of diesel fuel and
introduces it into the combustion chamber. With the
thermostart installed, all the five positions of the
keystart switch are connected as shown in Figure 3.
However, if the automatic thermostart is not installed,
the starting motor operates at position (4) while as
position (5) is left unconnected (see Figure 3).
IMPORTANT :
Never push or tow the tractor to start
the engine. Doing so may overstress the drive train.
NOTE:
A safety start switch prevents operation of the
starting motor unless the transmission range lever is in
the neutral (N) position.
Before starting the engine, always carry out the following
procedure:
l
Sit in the driver’s seat and ensure that the parking brake
latch is firmly applied.
l
Push the stop control knob fully in.
l
Ensure that both gearshift levers are in neutral and
that the P.T.O. lever is in the disengaged position.
l
Move both hydraulic lift control levers fully forward.
l
Place the remote control valve levers in neutral.
WARNING : Start the tractor only from the driver’s
seat. If the key-start switch is bypassed, the
engine may start inadvertently with a gear selected and
cause sudden and unexpected movement of the tractor
or a tractor runaway. Wear eye protection when starting
the tractor with jump leads or when charging the battery.
For standard tractors (without automatic
thermostart)
l
Open the hand throttle halfway, depress the clutch
to ease the load on the starter motor and turn the
key-start switch fully clockwise to position (4) to
operate the starting motor. Crank the engine until it
starts but do not operate the starting motor for more
than 40 seconds and then allow the key to return to
position (3).
l
Return the throttle to the idle position and check that
all warning lights extinguish and gauge readings are
normal.
