Lubrication Procedure
General
The 686 / 686 HT series printers are factory equipped with either composition
bearings not requiring lubrication or pre-lubricated bronze 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.
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.
Bronze Bushings
1)
After extended periods of time, card dust will build up in and around the
bushings. This should be cleaned to allow free movement of the device
mounted.
2)
Turn off the power to the printer.
3)
Remove the device mounted in the bushing that shows signs of a cleaning
required.
4)
Wipe down the part with alcohol and a cloth. The Velcro pad may be used to
clean heavy buildup.
5)
Wipe out the bearing and surrounding surface with a cloth; avoid using alcohol,
as that will wipe away the natural oil impregnated into the bushing. Check for
heavy build-up and remove.
6)
Add a drop of SAE 30 WT oil if available. If not - use one drop of lightweight
spindle oil.
