Weekly
Check the main air supply filter for any accumulation of oil or debris. Empty the filter bowl before it is
filled to the maximum level indicated on the side of the bowl.
Check the smoothness of the up/down movement of the Cross Seal Bar. If the bar chatters at all or does
not move smooth, wipe the rods clean and apply a coat of sewing head oil to keep the rods lightly
lubricated. This will improve the performance and extend the life of the bearing and keep the shafts for
rusting. If the condition persists after application of the lubricant, check the tension and alignment of the
two synchronizing chains. Also check the condition of the Cross Seal Guide rods for any unusual wear.
Monthly
Check the chain tension on all four motor drives. Adjust as needed.
Check the tension of the input and output belts. Adjust as needed.
Quarterly
Check the conveyor bearings and other pivot bearings and lubricate using PTFE based grease.
Check the condition of the Seal bar tape and the silicone rubber cushion below it for any through cuts
particularly in the area where the hot knife cuts through the plastic. If the PTFE tape or cushion or both
is cut or damaged, the whole setup must be replaced.
Bi-Annually
Replace the air supply filter element.
Lockout Procedure
Make sure all seal bar cylinders are in the desired position (up or down). It is necessary to observe the
position of these cylinders. When the main air is turned off to the machine, the cylinders are
pneumatically locked in the position they are at that moment.
Turn off the main air lockout valve and let the airlines and the air tank bleed-off completely.
Install a lockout padlock in the air lockout valve.
Turn off the main electrical switch and lock it out.
Wait until all seal bars cool off sufficiently before attempting to work near any of the seal bars.
Note: Do not lock seal bars in the down position if they are hot.
