Spring Tune-up for Roofing Tools

Taking the time to perform maintenance on your machine now can save you downtime during the roofing season. We recommend you do the following things:

• Inspect element for signs of cracking outside and debris inside
• Ensure mica tube is in good condition
  • The mica tube is the insulation sleeve that surrounds the element
• Check that motor brushes are not worn
  • If they are less than 6 mm long, replace them or bring tool in for service
• Clean any debris from air filters
• Check that nozzle ends are not pinched
• While running cold, bend power cord a short section at a time from one end to the other
  • If the machine shuts off, the cord is damaged and needs to be replaced
• Ensure tool heats properly
• While tool is hot, thoroughly clean any material residue from nozzles
• Allow machine to cool completely before shutting off
• Additionally, for automatic tools check that:
  • Lock pin is not broken
  • Tires and green belt do not have cuts
  • The two rollers holding down the green belt roll freely and the screw just above each roller is tight
  • The nozzle position is correct
    • More information on nozzle positioning can be found on page 23 of the VARIMAT V2 manual or page 7 on the VARIMAT V manual
  • Weld a scrap piece of material to test the machine drive and tracking
