Maintenance Interval
The flexible driveshaft should be lubricated after each
30hours of operation.
Driveshaft Lubrication
Loosen the two screws on the bearing case and remove
the bearing case. The inner flexible driveshaft is easily
removed by gripping the end securely and pulling it
from the driveshaft tube. Lubricate the entire length the
flexible driveshaft and insert it into the driveshaft tube.

seats correctly into the driveshaft coupler. Re-install the
bearing case onto the driveshaft tube and tighten the
two screws.
