6 OPERATION
6.5 OPERATION OF THE MACHINE __________________________________________
1. Check the machine, look for worn, damaged or loose parts. Check the machine for fuel and oil leaks. Make
sure that all connections are tight. Make sure that all hoses and tubes are in good condition.
2. Check the fuel level, radiator coolant level, crankcase oil level and air cleaner is clean. When the engine is
cold, all additional fluids must be at the full level mark.
3. Make sure all cutting units are adjusted to the same height of cut.
4. Check all tyres for the correct pressure.
5. Test the Operator Presence And Safety Interlock System.
6.6 HOW TO START THE ENGINE ___________________________________________
The following procedure is for starting cold engines.
1. Ensure the FWD/REV pedal is in the neutral position, the mow and parking brake switches are off, the
throttle setting is in a mid position and the operator is in the seat.
2. The glow plugs are auto timed depending on the coolant temperature for operating the starter motor (This
should only take a few seconds).
3. Turn the ignition switch to the “Run” position and wait until the yellow (Glow plug indicator) LED turns off,
then turn ignition switch to the “Crank” position until the engine starts.
4. When the engine starts, release the key immediately and it will return to the “Run” position.
5. If the engine does not start, return key to the “Off” position and repeat the above procedure.
NOTICE
Adjust the seat to make sure all controls are within reach and will operate through the full range of
movement.
1. Set the seat for the operators weight, height and reach.
2. Set the seat so that you can see the cutting units and the area around them.
3. Set the seat position for distance from the traction pedal. Check you can reach all the controls
easily.
NOTICE
1. If the engine fails to start after two attempts, wait 20 seconds and try again.
2. The starter motor must not be run continuously for longer than 30 seconds or it may fail.
3. If the red LED’s on the display flash whilst starting, one of the safety interlock switches has not
been set correctly.
