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

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.
