5 HOW TO USE THE MACHINE
5.1 SAFETY RECOMMENDATIONS
The machine must only be used for the purpose for which it was designed (cutting grass). Do not tamper with or
remove the safety devices fitted on the machine.
REMEMBER THAT THE USER IS ALWAYS RESPONSIBLE FOR DAMAGE AND INJURY TO OTHERS.
Before using the machine：
–read the general safety regulations, paying particular attention to driving and cutting on slopes；
–carefully read the instructions for use, make sure you are familiar with the controls and know how to stop the blades
and the engine quickly;
–never put your hands or feet next to or beneath the rotating parts and always keep away from the exit.
Do not use the machine when unwell or under the influence of medicine or any other substances that can reduce
your reflex actions and your ability to concentrate. It is the user's responsibility to assess the potential risk of the
area where work is to be carried out, and to take all the necessary precautions to ensure their own safety and that
of others, particularly on slopes or rough, slippery and unstable ground.
Do not leave the machine on high grass with the engine running to avoid the risk of starting a fire. Ensure grass
cuttings are cleared from the tractor to avoid a potential fire.
Do not use the machine on slopes with longitudinal gradients of more than 15°(27%); do not use
the machine on slopes with lateral gradients above 10°(18%). If the machine is likely to be used
mostly on sloping ground fit counterweights beneath the cross-member of the front wheels. These
improve stability at the front and reduce the chances of tipping over.
All the references relating to the positions of controls are described in chapter 4.
5.2THE SAFETY DEVICES OPERATION
The safety devices work in two ways:
–they prevent the engine from starting if all the safety requirements have not been met;
–they stop the engine even if just one of the safety requirements is not met.
a) To start the engine, it is necessary that:
–the blades are not engaged ；
–the parking brake is engaged and the transmission is disengaged ；
–the operator sits on the seat;
b) The engine stops when:
- the operator leaves his seat while mowing or driving;
5.3DIRECTIONS BEFORE STARTING WORK
Before starting to mow, it is necessary to carry out several checks and operations to ensure
you can work efficiently and in maximum safety.
5.3.1 Seat adjustment
