3M 39600 manual Maintenance, WARNING - Turn off electrical power supply and disconnect, Cleaning

Maintenance

The case sealer has been designed for long, trouble-free service. The machine will perform best when it receives routine maintenance and cleaning. Machine components that fail or wear excessively should be promptly repaired or replaced to prevent damage to other portions of the machine or to the product.

WARNING – Turn off electrical power supply and disconnect

power cord from electrical supply before beginning maintenance. If electrical power is not disconnected, severe injury to personnel could result.

Cleaning

Note –Never attempt to remove dirt from taping heads by blowing it out with compressed air. This can cause the dirt to be blown inside the motor and onto sliding surfaces which may cause premature equipment wear. Never wash down or subject equipment to conditions causing moisture condensation on components. Serious equipment damage could result.

Regular slotted containers produce a great deal of dust and paper chips when processed or handled in equipment. If this dust is allowed to build-up on machine components, it can cause component wear and overheating of drive motor. The dust build-up can best be removed from the machine by a shop vacuum. Depending on the number and type of boxes sealed in the case sealer, this cleaning should be done approximately once per month. If the boxes sealed are dirty, or if the environment in which the machine operates is dusty, cleaning on a more frequent basis may be necessary. Excessive dirt build-up that cannot be removed by vacuuming should be wiped off with a damp cloth.

Lubrication

Like most other equipment, the case sealer must be properly lubricated to insure long, trouble free service. Most of the machine bearings are permanently lubricated and sealed and do not need to be greased. The drive motor is also permanently lubricated and does not require additional lubrication.

Figure 4-1 illustrates the frame points which should be lubricated every 250 hours of operation. Lubricate the rotating and pivoting points, noted by the arrows, ( ) with SAE #30 non-detergent oil.

Lubricate the points noted by ( )with a small amount of multi-purpose grease.

Note –Wipe off excess oil and grease. It will attract dust which can cause premature equipment wear and jamming. Take care that oil and grease are not left on the surface of rollers around which tape is threaded, as it can contaminate the tape's adhesive.
