STARTING
Starting the engine
Set the forward/reverse lever (29) in neutral. The
engine can only be started with the lever in neutral.
Make sure that the parking brake knob (35) is
really pushed in. If the parking brake is not
applied, the roller may start to roll when you
start the engine on sloping ground.
Press the accelerator down about ¼.
Turn the ignition switch (21) to position “I”. The switch
lights until the demanded pre-heater is ready. Ensure
that the fuel gauge (2) and voltmeter (4) show readings
and that the oil pressure warning lamp (6) is on.
Within 10 seconds after the pre-heater is ready:
Briefly press the starter button (20). Release the button
as soon as the engine fires.
Do not run the starter motor too long;
preferably wait a minute or so if the engine
does not start.
Warm up the engine at idling speed for a few minutes,
longer if the ambient temperature is below +10°C (50°F).
Check while warming up that the warning lamp for oil
pressure (6) is out, and also that the voltmeter (4)
indicates 13–14 volts. The warning lamp (36) for the
parking brake should still light.
After warming up the engine, ensure that the tempera-
ture gauges for transmission oil (11) and coolant (3)
show readings.
Ensure that ventilation (evacuation) is
adequate if the engine is run indoors. Ie,
danger of carbon monoxide poisoning.
Check all tires for correct pressure:
Minimum pressure 2.5 kg/cm² (35 psi)
Maximum pressure 8.5 kg/cm² (120 psi)
Tire pressure can be checked with the tire pressure
gauge (8). Move the control valve lever (26, fig. 19) to
its middle position. Up to increase and down to reduce
(optional).
Test the driving brake. It is essential that
the brakes are in working order.
Test by pressing the brake pedal. The brake pressure
gauge (9) should then indicate 6,5 bar (94 psi). This is
the maximum pressure.
Do not move the roller before pressure of
the system has reached the specified
operating level.
Test the brake by pressing the parking
brake knob (37) while the roller is running
slowly forward.
