  • Page 25: Part Iii. Maintenance And Repair

     Repair. Major service, including the installation or replacement of parts, should be performed only by a qualified service technician. Obtain factory approved parts from Powerhorse Product Support at 1-866-443- 2576.  Replacement parts. If a part needs replacement, only use factory- approved repair parts.

  • Page 26: Chipping Knives

    Maintenance and Repair 1. Chipping Knives There are chipping knives that are mounted on the large spinning knife rest/wheel which drives the knives past the incoming material at a high rate of speed and causes the ―chipping‖ action. Routine inspection of the chipping knives for sharpness will ensure the chipper/shredder is operating at full efficiency.

  • Page 27: Shredding Hammers/Knives

    Maintenance and Repair 2. Shredding Hammers/Knives There are four shafts attached to the flywheel. Each shaft has 5 hammers/knives. As the large spinning wheel rotates, the hammers/knives rotate and pulverize the shreddable material. The material is broken down and passes through the shredding screen and exits the machine. Routinely inspecting the hammers/knives and shredder screen for damage will ensure the shredder is operating correctly.

  • Page 28: Belt And Sheave Care

    Maintenance and Repair 3. Belt and Sheave Care Proper belt tension and sheave alignment is vital to chipper/shredder performance. Here are a few problems that can occur when belts and sheaves are not properly maintained or cared for. Loose Belt: A loose belt will slip and then glaze over. Once this happens the belt will not transmit power to the knife rest which can cause the chipper/shredder to clog and also cause excess sheave wear.
  • Page 29 Do not operate the machine without making sure all guards are in place after servicing. Note: New belts require a “break-in” period of approximately 2 hours. Readjustment may be necessary after “break-in.” Note: Use only factory recommended belts. Contact Powerhorse Product Support at 1-866-443-2576.
  • Page 30 Maintenance and Repair Sheave Installation Before installing sheaves, make sure the chipper/shredder shaft and engine shaft are clean and square or parallel to each other. This can be done by & Alignment using two large carpenter’s squares. Assemble bushings into sheaves by leaving them loose, then slide them on the shafts and install the key.

  • Page 31: Maintenance Schedule

    If a part needs replacement, only use parts that meet the manufacturer’s specifications. Replacement parts that do not meet specifications may result in a safety hazard or poor operation of the chipper/shredder.
