Lubrication Procedure
General
The 636 / 656 series printers are factory equipped with either composition bearings not requiring lubrication or
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
2)If lubrication is omitted, knife will squeak and draw attention to required lubrication.
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
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.
