Before performing any maintenance always check that the machine is fully turned off and unplugged.

Always inspect the flexible shaft before each use. If there are potential weak points, or the shaft is damaged,
cut off the damaged length using a band saw or replace the entire shaft as needed.

For safety and efficiency, always keep the machine and its motor, drive unit, ventilation and cooling slots clean.

Remove the hand guard and check that the screws for the shaft socket are securely tightened (weekly).
5.
Check that all the bolts and screws on the machine are securely tightened.

It is recommended that the oil in the bevel gear should be changed about every 12 months. Only use regular oil
developed for gearboxes.
REPLACING CARBON BRUSHES
Remove and check carbon brushes regularly and replace when worn down to the limit mark. See page 16 for
maintenance intervals. 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.
The complete motor needs to be removed in order to change both of the carbon brushes. Follow the steps shown
below.
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.
Step 1.
Open Allen bolts and remove
the hand guard.
