After parking in moist conditions over a longer period, the piston rods should
be lubricated in oil to avoid rusting.
Backlash in the rings
In some cases due to normal tolerances of the castings washers might be
placed between the bearings and the rings and also between the lock washer
(A) of the shaft end and the outer ring. If unacceptable backlash occurs be-
tween the rings during use, it can be reduced by mounting a washer of a suita-
ble size to minimize the backlash (see 'Replacement of rings/bearings').

Cleaning and maintenance
When the season is over, the machine should be cleaned of soil and moist col-
lecting materials. This will also ease future maintenance and repair of the ma-
chine.
Check that the rings easily turn and are intact coincident with no unnecessary
backlash in the bearings.
Check the wear of the linkage's slide bar (nylon rail) and make sure that the
Taptite screws (self-tapping screws) do not stick out on the surface.
