Safety rules
WARNING
- Always mount the blade guard on the mowing bar, both
during transport and at the end of work.
- Move the PTO control lever to neutral position and
stop the engine before proceeding with any cleaning,
lubricating work or adjustments.
- Never ever work with the mowing bar unless the safety
devices of the walking tractor are perfectly efficient.
- Before using the mowing bar with the reversing walking
tractor, it is essential to move the reverse shuttle control
lever in the right running direction so that the Reversing
safety device is able to operate correctly.
- Never ever work on slopes exceeding 30° (Fig. 2). Never
work in an up or down direction, but across the slope,
where the gradient is minimum, taking great care when
changing direction.
