DRIVING THE MACHINE
WARNING
When using the machine for the first time it is advisable to get the feel of it by executing
manoeuvres on flat ground free of foreign objects. Cut in a straight line at low speed,
slightly overlapping the section cut previously.
After switching on the engine following the instructions given in the previous paragraph:
1. move the SLOW/FAST speed handle ( Fig. 2 Ref. O) to the slow position.
2. then move the gear selector handle (Figure 2 Ref. N) to the 1
st
gear setting, ensuring that
the handle is engaged correctly.
WARNING
If the gear is not properly engaged it may disengage, giving rise to a potentially dangerous
situation. If the gear engages with difficulty, partially engage the forward clutch for an instant
(lever in Fig 1 Pos. A), before trying to engage the gear again.
For safety reasons it is advisable to start work using the lowest gear, gradually working up
to a higher gear if compatible with work conditions.
3. Engage the flail rotor clutch control lever (Fig. 1 Ref.D) after accelerating a little.
WARNING
Select a suitable cutting height to prevent the flails from striking foreign objects.
