Support anchors and customer-supplied supports must be adequate for all foreseeable
loads, including any offset drive weight
Hardware tends to loosen during shipment, and should be tightened correctly. Tighten all

your unit. As sections are assembled into place, check all hardware for tightness. You are
responsible for any damage caused by loose hardware that was not tightened at this time.
Recheck hardware regularly, to protect your investment and your workers.
Check the access to operator positions. There must be room around the various parts of

slow down, or otherwise operate the machine can result in a dangerous and costly
accident. Maintenance confusion can result in ruined controls unless the directions are
read and understood. Always keep copies of these directions in a clean location where they
