7.1.2 Check the cutting blades
The blade rotates at high speed, so abnormal wear or damage to a blade can cause the
machine to vibrate excessively. In addition, hitting a stone or other hard object lying in the
field can make the blade lose its sharpness. For this reason, it is necessary to check the
condition of the knife and especially the fasteners (screws, washers and bushings) before
use. The reorder codes for the individual components are displayed to facilitate replacement.
How to check the blade
The knife rotates at high speed, so abnormal wear or damage to a knife can cause severe
vibrations to the machine. To check the knife, Park the machine in a flat ground; switch the
battery OFF and remove the switch key. Lift and secure the front of the machine in order to
accede easely to the blades. Avoid a precarious and unsafe position. If the machine falls, it
could crush you and cause you serious injuries.
- Check that the blade rest is straight and not bent.
- Check that the blades are regular and not deformed
- Check whether the fastening screws are properly tightened (do not exceed the maximum
tightening torque of 130 Nm)
- Check that the blades are sharp enough.
To sharpen the blades, follow the instructions in section 7.2.4.
If the screws are loose, replace the knife fastening screws on both sides If the knives
are deformed, replace the knives and fastening screws immediately If the blade holder is
deformed, replace it with a new holder.
DANGER:
Do not try to use the machine if the blade is not in good working order: Structural failure of
the blades or their fastening systems can lead to serious and even fatal accidents
7.1.3 Radio control's Battery charge
The radio control battery is a critical part of the machine. If the battery
is weakly charged, the machine cannot be controlled. For this reason, 2
batteries are provided for safety. It is strongly recommended to charge
both batteries before use.
ATTENTION:
If the battery have low charge the machine will stop.
