Lubrication may be required sooner if environmental conditions require it. If the lubricant appears
to have dispersed or is dry or crusted, reduce the maintenance interval.
The up/down screw bellows should completely cover the screw. If either of the bellows is
damaged, replace it immediately. Before installing the new bellows, clean the up/down screw and
the nut thoroughly with extraction naphtha. The acme screw nut (Part No. 094243) should be
replaced if the end play is larger than 1.25 mm (0.0492”).
3. Check the up/down belt tension after the first 20 hours of operation and every 100 hours thereafter.
