‘NEUTRAL’ position. Then put all the
auxiliary hydraulic control levers in
their neutral positions. Move the hy-
draulic quadrant levers to the ‘DOWN’
position.
4. Set the hand throttle to the fully open
position.
5. Push the fuel cut-off control fully ‘IN’.
6. Turn the starter switch to the third
position clockwise (heat) and hold it
there for 15 to 20 seconds.
7. Depress the clutch pedal.
8. Turn the key to the fourth position
clockwise (start) to engage the starter.
9. If the engine fails to start within 15
seconds, return the key to the (heat)
position for a further 10 seconds.
IMPORTANT
If the engine fails to start, ensure that
the starter motor pinion is at rest before
re-engaging the starter motor.
10. Re-engage the starter by moving the
key to the (start) position.
11. When the engine starts, return the key
to the (heat) position until the engine
runs smoothly, then allow the key to
return to the (auxiliary) position.
12. If the engine does not start, repeat the
reheat and cranking cycle, as described
in operations 8 and 9. After three at-
tempts, if the engine fires but fails to
pick up, turn the key to the (heat) po-
sition for several seconds, then to the
(start) position. Failure to start after
these attempts will necessitate carry-
ing out the checks given in procedure
8 in ‘Normal Starting -Warm Weather’
(page 34).
13. When the engine starts set the hand
throttle to a fast idle position (approx-
imately 1200 rev/min) for two or three
minutes, before putting the engine un-
der heavy load.
STARTING THE TRACTOR WITH
JUMP LEADS
If the tractor has a discharged battery
(A Fig. 3), it can be started with either a
slave battery (B) or the battery of another
vehicle. Follow the procedure described
below.
DANGER
Operate the starter motor only from
the operator’s seat. If the key-switch is
bypassed the engine may be started in-
advertently with the transmission in gear.
WARNING
Wear eye protection when charging the
battery or starting the engine with a slave
battery.
1. DO NOT use a slave battery of more
than 12 volts.
2. DO NOT connect across the terminals
on the starter motor.
3. Access the battery in front of the trac-
tor, see page 92.
4. Connect one end of the jump lead to
the slave battery positive (+) terminal
