MAINTENANCE, LUBRICATION, & ADJUSTMENTS TO MOTOVIBRATOR
WARNING: The Motovibrator must be serviced by qualified personnel.
Disconnect the power supply to the motovibrator during disassembly and re-assembly operations on the
protection devices (earth and terminal board covers), checking current absorbed.
Remove the terminal board cover, power the motovibrator, and use ammeter pliers on all the phases to
ensure that the current absorbed does not exceed the value on the rating plate. If this is not the case,
ensure that the frame or flexible structure on which the motovibrator is positioned conforms to the
correct rules for application. Never touch the motovibrator when it is operating. Never start the
motovibrator without the protective covers on the earth and terminal boards. After a brief period of
operation, again check the elements fixing the motovibrator to the frame.
INTENSITY OF THE VIBRATOR
WARNING: The operation must be carried out only by a qualified technician, with the
power supply disconnected.
Remove the side covers after unscrewing the bolts.
Loosen the main bolt, shift the movable weight (or the lamellar weight) to the required position and
tighten the bolt again after fitting the respective washers. The weights must be adjusted so as to be
perfectly equal and in the same direction on both sides. Refit the covers, after replacing the OR sealing
ring without damaging it. N.B.: ALL STANDAR MOTOVIBRATORS ARE SUPPLIED WITH THE WEIGHTS
ADJUSTED TO THE MAXIMUM.
NOISE LEVEL
The weighted equivalent continuous noise level of the motovibrators is NEVER higher than 76 dB(A)*.
*measurement made in normal operating conditions in accordance with standard ISO 6081/86, with
simulated load consisting of a steel bench fitted on springs. It is, however, COMPULSORY for the
manufacturer of the machinery on which the motovibrator is fitted to measure the final noise levels on
the finished machinery or plant. It is also COMPULSORY for the employer to measure the noise levels in
the work area where the machinery or system with the motovibrator is installed. These measurements
must be done before starting up the plant. It is also compulsory to use suitable devices for personal
protection and train operators as specified by L.D. 626.
