  • Page 70: Drum Wear

    ROUTINE MAINTENANCE DRUM WEAR: What causes drum wear? 1� Again dull knives are the biggest culprit and will make the operator force feed the machine, which can cause wear all the way around the straight edge drum. 2� Force feeding can cause the material to ride against the drum all the time causing more pressure and wear on the drum it also takes more horse power and fuel to operate.

  • Page 71: Chip Quality

    2� It is not recommended that you change the knife lengths to try and get the chip quality you want. Morbark has done extensive factory testing with this and you will get the same results by slowing down or speeding up the feed system.

  • Page 76 ROUTINE MAINTENANCE GRINDING BABBITTED KNIFE 29° When grinding the knives, extreme care must be taken to ensure that excessive heat isn’t put into the knife edge. Excessive heat (indicated by discoloration of the knife edge) will lead to microscopic cracks that can cause the knife to break when it is put back into service. DO NOT attempt to use knives that have been exposed to excessive heat from sharpening! Once the discoloration appears, the knife can not be made serviceable again by simply removing the discoloration.
  • Page 77 ROUTINE MAINTENANCE Babbitted Knife GRINDING BABBITTED KNIFE CON'T 4� Use a honing stone to remove any burr edges left from filing. This procedure increased knife life up to three times and has reduced the amount of steel the grinder takes off the knife. It may be necessary to do some experimenting with this back grind for your particular application.
