7.3.3. ANNUAL CHECK
Perform this check with the MACHINE STOPPED and the power supply DISCONNECTED (OFF).
The annual check is recommended by the manufacturer to check the functionality of the entire mechanical kinematics
of the “emergency bumper”.
The figure shows the components which contribute to the protection device functionality.
− It is recommended to have the listed operations performed by personnel of recognised competence in the
mechanical and electrical field (even when it is not required to disassemble the components).
− In addition, it is recommended, when possible, to keep the machine on the ground, without lifting it.
The list mentions the maintenance interventions to be performed.
1. Check that all the levers which activate the safety switches (K) can move freely and that guides are free from
seizures.
2. Check that mechanical moving components are free from dust.
If necessary, use a compressed air gun or an aspirator to remove the residues.
3. Check that all the components feature their fastening elements (screws, nuts, washers, etc.).
Order all the missing fastening elements in order to restore the normal operating conditions.
4. Check that all the parts of the device are correctly fastened.
If necessary, tighten them.
5. Check the sensitivity of the protection device on its whole sensitive surface.
6. Visually check that the entire front profile of the bumper is not worn, deformed or cut.
Immediately contact the manufacturer or authorised service centres if any relevant discrepancy from points 1-3-4-5-6 is
found.
