6.2 Feed belts
Approximately once for every twenty hours of machine operation, clean the feed
belts of the unit with soap and water. Turn the machine off and on repeatedly to make
sure that the entire lengths of the belts are cleaned.
6.3 Holdback wheel maintenance
The holdback wheel does not rotate; hence it will wear a flat spot over time. If this
occurs, simply loosen the center screw of the holdback wheel and rotate it to expose a
fresh surface.
6.4 Blade Maintenance
For each 40,000 pieces of mail processed, coat both the upper and lower blades
with a blade emollient such as Premier Brand Trim Ease Lubricant (Martin Yale
#MRS037046, available through your Martin Yale Dealer).
