Checking the carbon brushes
X
Check that both carbon brushes are at least the minimum length.
Note:
If one carbon brush is smaller than the minimum length, both carbon
brushes must be replaced.
Inserting the carbon brushes
1. Install carbon brush (on both sides of drive motor). Pay attention to the origi-
nal position and location of used carbon brushes, to avoid damage and spar-
king on the collector.
2. Screw on cap with o-ring and tighten with a screwdriver hand tight.
Note:
If you have installed new carbon brushes, the drive must be run for ap-
prox. 5minutes without the flexible shaft attached.
