Ocmis Irrigazione S.p.A. – INSTRUCTION AND WARNING MANUAL – Translation of Original Instructions
MUMR-R1.02 .EN - 31/07/2015
CHAPTER 7 - Maintenance
•
Affi x specifi c warning signs such as: EQUIPMENT UNDER MAINTENANCE - DO NOT POWER ON, WORK IN PROGRESS - DO NOT OPERATE
or DO NOT START (see picture below) at the access areas to the machine and any part of it where the maintenance operation is carried out,
ensuring these signs are clearly visible.
DANGER
Prior to starting maintenance operations affi x the signs indicating machine status under maintenance in order to ensure that:
•
The machine is stationary and safely placed in order not to cause shifting and/or accidental and sudden actuations.
•
There is no pressure in the piping delivering water to the machine.
•
The hydraulic circuits are locked or de-pressurised if the operations concern them.
•
The turbo-gearbox is in neutral.
•
The traveller wheels are blocked.
•
The internal combustion engine is off and cold (if the machine is equipped with it).
Should any other person start the machine or operate the controls during maintenance or lubrication, serious hazards might be created of injury or
death for the maintenance technician.
Always place the WARNING PLATES: on the controls of the turbo-gearbox, on the levers of hydraulic actuators, on the water delivery pump and on
the internal combustion engine, to warn others of the machine downtime for maintenance in progress and not to actuate anything that might endanger
the maintenance technician. If necessary, attach other identical warning plates around the machine.
•
Voltage may cause death by contact. Always operate with the utmost caution and according to accident protection rules in force.
•
Contact with toxic or harmful products may cause damage to persons and the environment. Always operate with the utmost caution, according to
the information set out in the safety data sheets of the products and to the safety standard in force.
•
Operating machines feature moving parts that may cause severe injury to people. In this connection, maintenance operations related to checks,
disassembly or replacement of machine components or on the control unit must be performed with machine off and power supplies disconnected
and locked.
•
Prior to performing maintenance operations on components, ensure the fl uid systems are not pressurised. Prior to operating, maintenance
personnel must ensure fl uid power supplies are disconnected and pressurised systems have been drained. To this end, prior to operating on
pressurised components, the internal pressure of the machine undergoing the operation must be reduced to the same value as ambient pressure.
•
Prior to performing maintenance operations on hot parts, ensure they have cooled down. Caution - burn hazard. Use suitable PPE.
DANGER
Prior to starting maintenance operations or removal of jammed machine parts, disconnect and padlock/lock all power sources
and discharge all fl uid power systems.
•
Keep away from holes, nozzles and/or bleed cocks during operations to discharge circuit pressure.
•
Keep away from any component that might be actuated by the oil hydraulic pressure, if this has not been completely discharged from the circuit.
•
Ensure all fi ttings and couplings are properly tightened, prior to pressurising the machine after a repair operation.
•
Ensure units with vertical actuation are placed in the low rest position, or alternatively supported with adequate lifting systems, in order to prevent
accidental motions or drops, especially when the actuators or devices that move them need to be replaced.
•
Prior to performing maintenance operations on movable parts, ensure the shutters are correctly inserted.
DANGER
Prior to starting maintenance operations secure vertical units with movement or drop hazard (if any).
•
Never bypass the safety and protection devices installed on the machine. Should this be required, signal the condition with suitable warning signs
and operate with the utmost caution. Restore all safety and protection devices as soon as possible.
•
Failure to connect the equipment and the structures in general to the ground may cause severe injury to people. Always ensure the grounding
connections are in place and compliant with the standards.
•
Prior to starting up the machine following a maintenance operation, always ensure that the maintenance personnel are at a safe distance and that
tools or materials used for maintenance have been removed form the machine and from its immediate vicinity.
•
Installation and use of the equipment must always comply with accident prevention standards. All moving parts and transmission parts must be
protected against accidental contact. Always ensure all guards are in place, correctly positioned and closed before starting up the equipment.
•
Prolonged overloads or faults may cause overheating of the equipment with production of harmful fumes; immediately disconnect the power
supply and do not approach the equipment until the fumes have been dispersed through adequate ventilation and the equipment has cooled
down. Avoid inhaling the lingering fumes during repair operations.
•
Do not use water jets in the event of fi re, especially on electrical equipment: immediately disconnect all power supplies and use CO2 extinguishers.
Alert the site's fi re fi ghting service or the Fire Services.
•
During maintenance operations use appropriate clothing and personal protection equipment (shoes, face shields and safety gloves, etc. in
compliance with the provisions of chapter 4), according to the type of activity to be performed. When operating on higher parts, use safety fall
arrest equipment.
•
It is forbidden to wear personal clothing and items such as chains, bracelets, etc. as they might get entangled in the machine and in the equipment,
act as conductors and cause entrainment.
DO NOT
START UP

PROGRESS
DO NOT PERFORM
ANY OPERATIONS
