Engine Operation Warning System
The engine will automatically be shut down in the event of loss of lubrication oil
pressure or coolant overheat. Illumination of the relative warning lamps occurs if these
conditions prevail. Testing the oil lamp occurs automatically when the ignition switch
is initially turned ON. The water temperature warning light will only illuminate when
cooling water reaches 110°C.
Engine Speed Regulation
The throttle speed switch is a spring centred switch operating an electric variable speed engine
control. The engine speed is between 1200 and 2000 rev/min to suit sweeping conditions. The Eco
Override button (Q), need pushing to increase engine RPM higher than 1500.

If the truck and auxiliary engine use a single fuel tank. When the fuel gauges reaches ¼ full,
stop the auxiliary engine as there is a chance it could run out of fuel, meaning the fuel system would
need to be bled again.
