Apply grease to the
lifting screw if needed (should be done annually or for every 250
Powerwalls installed, whichever comes first). To apply grease, use a
small amount along the entire threaded surface of the screw, and cycle
the carriage up and down a few times.
Note
The recommended
lifting screw grease is the McMaster 1243K31 Magnalube G as outlined
in Serviceable
Parts.
Confirm the lifting
screw is not bent.
Confirm that only the
Camco 3/4" hex socket is being used to
run the lifting screw.
Note
The recommended hex
socket is the Camco 57363 3/4" hex socket as outlined in
Serviceable
Parts.
Inspect the dolly tires:
Fill the tires if needed
(recommended pressure is 45 psi).
Confirm the tires are
free of debris and significant wear.
