2.3 INSTRUCTIONS FOR PROPER AND SAFE USE
IMPORTANT ! Radio remote control user MUST:
- Check the correct mechanical operation of the STOP button before every operation.
- Check the correct operation of the control devices.
If there is a deterioration in the correct operation of the STOP button or functional abnormalities in the control devices, the
use of the radio remote control must be prohibited until the full restoration of the system’s functionality.
- Use the transmitter unit by holding it or fastening it to the body in a safe and stable manner to avoid it accidentally
falling.
- Be thoroughly familiar with the functions and features of the radio remote control and of the machine the receiving
unit is connected to.
- Before activating any movement of the machine, ensure that the operator’s position is such to ensure that:
- There is NO danger of tripping
- There is NO danger of loss of balance
- Allow to follow the movements of the machine and the load in view.
- Guarantee the safety conditions concerning those engaged in other operations, activities or work in the
work area of the machine and operator.
- Turn off the transmitting unit whenever the work is suspended, even momentarily, even if the device is equipped
with automatic shut-off.
- Switch-off the transmitting unit and disconnect the power supply of the receiver before performing any maintenance
on the radio remote control or on the machinery.
- Do not leave the transmitting unit unattended and switched on.
- Remember that the transmitting unit can operate the machine even when placed indoors and far from the receiving
unit, so improper use can cause severe damage to people and property
- Never wash the units with water jets, use a damp cloth only
- Do not use in shielded environments (e.g. inside the drum of the mixer).
- Charge the batteries in an environment that is not too hot, too cold, too humid or dusty.

the transmission of electromagnetic waves.
- Choose the installation of the receiver in a vertical position and easily accessible for maintenance operations.
- Avoid that the receiver is subjected to strong vibrations. Use vibration dampers if necessary.
- Always make sure that the value of the supply voltage complies with the rated voltage indicated on the rating plate
of the receiver.
- Use multi-pole connectors for the electrical connection of the receiver to the machinery to allow easy removal if
required.
- Use cables of suitable section, max. 2.5 mm2.
