Flexible driveshaft
[Model B20, B21]
Maintenance Interval
The flexible driveshaft should be lubricated after each 30 hours
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 qulling it from the driveshaft tube.
Lubricate the entire length the flexible driveshaft and insert it
into the driveshaft tube. If the tool attachment is connected to the
power unit, twist the flexible shaft while pushing to insure that it
seats correctly into the driveshaft coupler.
Reinstall the bearing case onto the driveshaft tube and tighten
the two screws.
Gearcase [Except for model B20, B21]
Maintenance Interval
The gearcase should be checked for lubrication after each 30
hours of use.
Gearcase Lubrication
Remove the cutting attachment and the boss adapter. Clean any
dirt and debris from the area between the boss adapter and the
gearcase. Remove the grease plug from the side of the gearcase.
While rotating the attaching shaft, inject lithium-base bearing lube
(P/N 211337) through the plug hole until the gearcase is full.
Reinstall the boss adapter and grease plug.
