INSTALLATION and START UP
Before start up:
• remove unnecessary keys and tools;
• restore all unit safety system;
• all preliminary checks have been done;
• verify plugs and screws tightening;
• there are no oil leaks;
• make sure no radial or axial forces are applied;
• verify correct unit alignment with the structure;
• verify motor power connection;
• therearenoobstaclesthatcaninuencethecorrectoperationoftheunits;
Start-up and running in:
increase gradually torque and rotation values until max values allowed are achieved.
After starting up :
• friction between moving parts must be absent;
• excessive noise and vibration must be absent;
• carry out functional tests to verify:
• correct functioning of the unit;
• correct functioning of the safety system of the unit;
• that values functioning are respected.
Brake test:
carry out engage/disengage test to verify correct unlock pressure value and the brake tor-
que value (correctvaluesaredescribedonthespecicexternaldrawings).
In case of malfunctioning:
1. interrupt and disable the functioning of the machine,
2. check and verify correct installation,
3. schedule an immediate/anticipated general overhaul of the gearbox unit.
Before installation check and verify:
• motor type and connection;
• that unit components are not damaged and that the centering parts are not rusty;
• unit installation diagram;
• oil level/lubricant and type of lubricant;
• correctpluginstallationandefciency;
• that the reduction gear screws and plugs have been tightened with correct values ;
• that there are no hazardous atmosphere in the work area.
To guarantee the correct unit installation:
• remove dirt and grease from the unit;
• lubricate spigots and coupling surfaces;
• centeringandxingtheunitwithoutforcing;
• dents or sparks must not be created/produced;
• friction between moving parts must be absent;
• installandxtheunitandallcomponentscorrectly;
• take care not to deform the contact surfaces.
Installationandstart-upmustbecarriedoutbyqualied,trainedandauthorisedpersonnel
In case of malfunctioning or failure:
1. disconnect the unit malfunctioning,
2. carry out a maintenance or repair plan,
3. replace the damaged or faulty components with new components.
MALFUNCTIONING
AND FAILURE
Disconnect unit malfuntioning and avoid accidental run of the unit.
Interrupt and disable the functioning of the machine/vehicle during maintenance ope-
rations, general overhaul or revision procedures (e.g. lifting the wheels off the ground,
turning off the work procedure...etc...) to avoid hurting operators and other people.
