Linear Bearings and Guides
Inspect seals and look for blowing out, ripping, or leaking. Inspect track and look for worn down spots on rails that indicate debris or burrs. Pull on bearing/component in all directions and feel for play/slop in non-desired directions. Move back and forth in intended direction and flag if force to move has increased dramatically from last inspection.
Inspect all motors/drives/gearboxes including Main Bagger, all conveyors, and reformer. Check oil levels, electrical connections, and listen/feel for unusual noises or vibration while under operation.
Inspect all belts/conveyors (bag caddy belts, bag conveyor belts, reformer belts). Look for cracks, flat spots, unusual wear lines. Observe while in motion and look for snags or skips.
Mechanically examine all structural/adjustable pieces of bagger (transfer arm, main carriage, opening arm, side tuck, tucking fingers, carriage floor, clamshell backstops, bag rack). Note any cracks, breaks, unusual wear and tear, etc.
Do a bolt/fastener/adjustable handle check around entire bagger. Note any missing pieces and make a comment of which bolts/fasteners are missing and what size they are.
Air and Vacuum
Inspect all air cylinder shafts and seals for wear and replace as necessary. Inspect all air lines and vacuum lines for cracks or kinks. Check that all hoses are snugly fit into fittings and that there are no excessive leaks at any fittings or connections. Check main air/vacuum train on back of machine and confirm function of pressure regulator, water trap, and air lubricator.
Inspect all doors and door latches for damage or bending. Energize the machine by resetting and confirm machine stops when door is opened for each door and E-Stop. Check that all floor anchors are present and tight.
