Lubrication Procedure
General
The 676 series printers are factory equipped with either composition bearings not
requiring lubrication, pre-lubricated bronze bearings, or pre-lubricated needle
bearings. The one exception is the rub cams on either end of the rotary knife.
Periodic cleaning of the printer and removal of dust will greatly enhance the length
of the time the printer will function.
Cam - Lubrication Procedure
1) Clean dust and residue from cams (using alcohol or other suitable solvent) daily,
or approximately every 100K cuts. Use any good quality general purpose grease
(not oil). Apply with cotton swab or other non-metallic device.
2) If lubrication is omitted, knife will squeak and draw attention to required
lubrication.
3) Some machines are equipped with a self-lubricating oiler system built into the
knife protector. This is an oil-wick system and will require 2-3 drops of SAE 30
weight oil weekly. Be sure wick is in contact with cam. If not, press wick
downward with any suitable blunt device that will fit through the oil cap.
Composition (Iglide) Bearings
1) If field replacement of an assembly fitted with an Iglide bearing is performed, a
single drop of spindle oil should be applied to assist in bearing break-in.
2) If, after long use, an Iglide bearing starts to "squeak", disassemble the component
containing the bearing and lightly abrade the shaft surface. Clean the bearing
(dust or old oil) with alcohol, re lubricate with 1 drop of light oil and reassemble.
No other printer lubrication should be required in normal use.
