or a similar lubricant. Re-install the vacuum
head assembly onto the shaft by rotating it
counter-clockwise (figure 6-7).
An accumulation of debris in the gear box, if not
removed, may damage the gear box oil seal. This
will result in loss of oil in the gear box. If the gear
box is operated without oil, severe damage may
occur.
While rotating the vacuum head assembly in
the counter-clockwise position, make sure that
it spins freely all the way down. If it begins to
require the slightest finger tip pressure, unscrew
it and brush off the threads.
The smallest grain of dirt or sand will obstruct
the threads. If you turn too far onto a grain of
dirt, the hub may become locked onto the shaft
of the gear box.
