Service & Maintenance
GB
The Belle Group ‘Vibratronic’ is designed to give many years of trouble free operation. It is, however, important that the simple regular
maintenance listed in this section is carried out.
It is recommended that an approved Belle Group dealer carries out all major maintenance and repairs. Always use genuine Belle Group
replacement parts, the use of spurious parts may void your warranty.
Because of various risks with regards to cleanliness we advise against washing and then applying new grease onto used and disman-
tled bearings during maintenance works and assembling them again. We recommend instead the use of original and new grooved ball
bearings or Poker bearings from Belle; these are already greased as required.
Service, connection and assembly may be accomplished only on the condition that:-
-
The electrical installation is dead.
-
Protected against reconnection.
-
All drives are in the STOP position.
In switch-on position, electrical installations and machinery contain live, naked wires or rotating parts. This could result in personal
injury and material damage should the covers and protection devices be removed contrary to regulations. This could also happen
under wrong handling and maintenance or misapplication. Dealing with devices equipped with power electronics the expert might
come accross another uncommon danger which so far he may not have encountered, i.e. the device still contains electrical voltage
even after the supply voltage has been cut off.

Observe the waiting period before opening the

Poker. In addition to the time of discharge,
which is about 90 seconds, wait and check for any residual voltage prior to starting work. The waiting
period is at least 2 minutes after the plug has been disconnected.
WARNING
-
During clamping work on the terminal board, the Poker must be dead.
-
According to EC standards concerning the electro-magnetic compatability, the electro-magnetic interferences are to be reduced by
using cable screens, cable section 1.5mm

. Cable screening must be done on both sides.
Periodic Mantenance
1. Only a qualifi ed electrician should work on the electrical parts.
2. Disconnect the Poker from the power supply before conductng any maintenance.
3. In all maintenance operations, original parts will be used.
4. If you have replaced the switch, ensure the bolts are tightened and the box is watertight.
5. After maintenance jobs all the parts must be assembled correctly.
6. Every 12 month or more frequently, depending on the use, it is recommended an inspection be conducted by an authorised dealer.
7. Monitor the wear of the poker by measuring the outside diameter (B) and length (A). Replace the housing or cap when the
diameter or length, in the smallest point, is less than the dimension specifi ed in the table according to the model:
