7B. Maintenance
Unclamp Liner Idler Roller
When not in use, leave the liner idler roller in the unclamped position. This will minimize the
possibility that permanent indentations will be made in the liner drive roller.
Lubricate Bearings
Primera recommends oiling the four bearings associated with the liner drive roller and liner
idler roller. Oil these four bearings after every 50,000 containers labeled. They should only be
oiled after the first 50,000 containers as they are lubricated with a special grease at the
factory. One drop of any machine oil or motor oil for each bearing should be adequate. This
maintenance is optional but will increase the life of the applicator for heavy users who apply
hundreds of labels daily.
Increase Label Pressure Roller Clamp Force
Over time as the liner drive roller and its bearings wear, the clamp force of the liner idler
roller against the liner drive roller will decrease and the roller may begin slipping on the liner.
To compensate for this decrease in pressure you can adust the clamp force by moving the
force adjustments screws on either side of the applicator to lower positions. To make this
adjustment, use a #2 Phillips screwdriver. For each screw, rotate it counterclockwise one-half
turn, slide it down in the slot, then retighten it. Both screws should be kept in the same
relative position in their slot. If the screws are moved too far down in their slot, it will be
difficult to clamp the linder idler roller. You may need to make this adjustment several times
throughout the life of the applicator. If you reach the bottom of the slot the liner drive roller
and bearings will need to be replaced.
