DEFECTS AND THEIR REPAIRS
In case of a malfunction, immediately stop the machine, turn off the motor and wait until the
mowing head is fully stopped. Before disconnecting any of the hydraulic hoses, check whether there
is no pressure in the hydraulics and remember to cut-off the oil feed from the tan to the machine's
hydraulics. Hot or pressurized oil leak may cause serious bodily injuries. For the sake of the
operator's safety, the machine must be stopped on even ground. All hydraulic cylinders and moving
elements must be completely locked.
