MAINTENANCE
1.
Before performing any maintenance always check that the machine is fully
turned off and unplugged.
2.
Carefully inspect the flexible shaft and its casing on a regular basis to ensure that there are no signs of wear
and tear. Change the flexible shaft and casing as and when required.
3.
For safety and efficiency, always keep the machine and its motor, drive unit, ventilation and cooling slots clean.
4.
Check that the screws for the shaft socket are securely tightened.
5.
Check that all the bolts and screws on the machine are securely tightened.
REPLACING CARBON BRUSHES
Remove and check carbon brushes regularly and replace when worn down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only
identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
