CH - USE AND MAINTENANCE INSTRUCTIONS
INSTALLATION
· The data shown on the identification name plate must correspond to the gear ordered.
· All the gears are supplied complete with permanent synthetic oil in a quantity that is sufficient for any assembly position.
· The gear must be fixed on a flat surface that is sufficiently rigid in order to avoid any vibration.
· The gear and the axis of the machine to be driven must be perfectly aligned.
· In the event that knocks, overloading or blockage of the machine are foreseen, the client must install a limiting device, joints, overload cut-out etc.
· Coupling with pinions, joints, pulleys and other parts must be done after the parts have been cleaned and knocks should be avoided whilst assembling as they could damage the bearings and other internal parts.
· In the event that the motor is supplied by the client, he must check that the flange and shaft tolerances correspond to a “normal” class; our motors satisfy this requirement.
· Check that the fixing screws for the gear and the related accessories are correctly tightened.
· Take suitable measures to protect the groups from any aggressive atmospheric agents.
· Where foreseen, protect rotating parts from any possible contact with the operators.
· If the gears are painted, protect the oil seals and the machined surfaces.
· All of the gears are painted RAL 9022 grey.
OPERATION AND RUNNING-IN
· To obtain the best performance the gears must first be runin by gradually increasing the power in the first few hours of operation, in this phase an increase in temperature is considered normal.
· In the event of defective operation, noise, oil leakage, etc. stop the gear immediately and, when possible, remove the cause. Alternatively, send the piece to our factory to be controlled.
MAINTENANCE
· The worm gears from size 03 to size 08 and the pre-stage modules are lubricated with permanent synthetic oil and therefore do not require any maintenance.
WAREHOUSE STORAGE
· If the warehouse storage will be for a long time, more than 3 months, the shafts and machined 87
surfaces should be protected using antioxidants and the oil seals should be greased.
HANDLING
· Care must be taken not to damage the oil seals and the machined surfaces when handling the groups.
DISPOSAL OF PACKAGING
CH - USE AND MAINTENANCE INSTRUCTIONS
· The packaging in which our gears are delivered should be sent to specialised companies for recycling if possible.
