9 MAINTENANCE
MAINTENANCE PROCESS
• Access to the onstage portion of the hoist is important when doing part of the maintenance work
and also on the offstage side at the electrical cabinet.
• Remove the two 7/32" Allen head screws that are at
the onstage end of the hoist.
This is a cover for both the Drum Shaft and the
Acme Screw. The cover does not have to be
completely removed, instead pull it down
out of the channels.
• The pictures below show the end view of the Drum
Shaft and Acme Screw (albeit without covers on).
• Take a Blue Shop towel or clean
towel spread a small amount of
the 3-in1 oil onto the towel and
wipe it on/over the Drum Shaft.
Use this first towel to clean the shaft
of dust and grit. Use a 2 nd towel
that is liberally anointed with the
3-in-1 oil to lubricate the shaft,
making sure to wipe all
around the shaft.
• Always use a clean towel when doing the first wipe down on the
Drum shaft to avoid spreading the grime from unit to unit .
• When lubricating the Acme Screw be sure to have as much of the screw showing as possible.
To achieve this, raise the batten to its highest point of travel. Take another Blue Shop Towel
as a backing towel to prevent overspray and spray the Acme Screw with White Lithium
lubricant. Just one quick pass usually suffices for lubricating this screw.
• Upon completing the lubrication, replace the cover making sure to fit the cover into the
channels on the aluminum backbone.
