    • Important Safety Instructions
      • 1. Read all instructions before using the tumbler.
      • 2. Refer to the Grounding Instructions for the proper grounding of the tumbler.
      • 3. Do not dry articles that have been previously cleaned in, washed in, soaked in, or spotted with gasoline, dry-cleaning solvents, other flammable or explosive substances as they give off vapors that could ignite or explode.
      • 4. Do not allow children to play on or in the tumbler. Close supervision of children is necessary when the tumbler is used near children. This is a safety rule for all appliances.
      • 5. Before the tumbler is removed from service or discarded, remove the door to the drying compartment and the door to the lint compartment.
      • 6. Do not reach into the tumbler if the cylinder is revolving.
      • 7. Do not install or store the tumbler where it will be exposed to water and/or weather.
      • 8. Do not tamper with the controls.
      • 9. Do not repair or replace any part of the tumbler, or attempt any servicing unless specifically recommended in the user-maintenance instructions or in published user-repair instructions that you understand and have the skills to carry out.
      • 10. Do not use fabric softeners or products to eliminate static unless recommended by the manufacturer of the fabric softener or product.
      • 11. To reduce the risk of fire, DO NOT DRY plastics or articles containing foam rubber or similarly textured rubberlike materials.
      • 12. Always clean the lint filter daily.
      • 13. Keep area around the exhaust opening and adjacent surrounding area free from the accumulation of lint, dust and dirt.

      • 15. If not installed, operated and maintained in accordance with the manufacturer’s instructions or if there is damage to or mis...
      • 16. Tumbler will not operate with the loading door open. DO NOT bypass the door safety switch to permit the tumbler to operate w...
      • 17. Do not put articles soiled with vegetable or cooking oil in the tumbler, as these oils may not be removed during washing. Due to the remaining oil, the fabric may catch on fire by itself.
      • 18. To reduce the risk of fire, DO NOT put clothes which have traces of any flammable substances such as machine oil, flammable ...
      • 19. Use the tumbler only for its intended purpose, drying fabrics.
      • 20. ALWAYS disconnect and lockout the electrical power to the tumbler before servicing. Disconnect power by shutting off appropriate breaker or fuse.
      • 21. Install this tumbler according to the manual. All connections for electrical power, grounding, and gas supply must comply with local codes and be made by licensed personnel when required.
      • 22. Remove laundry immediately after tumbler stops.
      • 23. Always read and follow manufacturer’s instructions on packages of laundry and cleaning aids. Heed all warnings or precaution...
      • 24. Do not tumble fiberglass curtains and draperies unless the label says it can be done. If they are dried, wipe out the cylinder with a damp cloth to remove particles of fiberglass.
      • 25. Always follow the fabric care instructions supplied by the garment manufacturer.
      • 26. Never operate the tumbler with any guards and/or panels removed.
      • 27. DO NOT operate the tumbler with missing or broken parts.
      • 28. DO NOT bypass any safety devices.
      • 29. Solvent vapors from dry-cleaning machines create acids when drawn through the heater of the drying unit. These acids are corrosive to the tumbler as well as to the laundry load being dried. Be sure make-up air is free of solvent vapors.
      • 30. Failure to install, maintain, and/or operate this machine according to the manufacturer’s instructions may result in conditions which can produce bodily injury and/or property damage.
