DANGER
Low tire pressure decreases machine side-hill
stability. This could cause a rollover, which

Important:
Maintain the recommended pressure
in all tires to ensure a good quality of cut and
proper machine performance. Do not under-inflate
the tires.
Check the air pressure in all the tires before
operating the machine.
