    GENERAL SAFETY PRECAUTIONS - READ ALL INSTRUCTIONS BEFORE OPERATING THIS HEAT TOOL • Do not operate this heat tool below 20 PSI or damage to the heat tool will occur. • Before using any heat tool, check all parts for proper function and damage to component parts including the hose, regulator and heat tool.
  • Page 5 GENERAL SAFETY PRECAUTIONS • When working with any type of heat or open flame, always keep a fire extinguisher close by. • Always wear safety glasses and gloves (flame retardant or leather is suggested) when shrink wrapping. Never obstruct or cover the air inlet at the back of the heat tool.

    REGULATOR OPERATION & MAINTENANCE Adjustable Hand Wheel 0 – 30 PSI Pressure Gauge – Adjusts PSI Setting of the Regulator POL – Attaches to Hose Adapter – the Propane Tank Attaches to the Supplied 25’ Hose Regulator Technical Overview: • The MEGR-6120 is a high capacity, pounds to pounds, industrial gas regulator. It is designed to conform to UL ®...
  • Page 8 This is a variable regulator assembly and the heat tool will operate properly between 20 PSI and 30 PSI. The pressure can be changed by loosening the hex nut located under the black, round hand wheel on the regulator assembly and then turning the hand wheel to the desired pressure. However, the optimum and factory recommendation is that you do not adjust the pressure and keep the regulator set at the factory setting of 22 PSI.
  • Page 9 2.Connect one end of the supplied 25’ hose to the hose adapter on the regulator and the other end of the hose to the heat tool. Tighten all fittings with the supplied wrench (left handed threads, so tighten counter clockwise). 3.Open the propane tank valve and check for any leaks by spraying a soapy water mixture on the fittings.

    STARTING THE HEAT TOOL 1.With your fingertips, pull the yellow safety first. If you do not pull the safety first, you will not be able to depress the trigger with the palm of your hand and ignite the heat tool. 2.With the safety pulled, slowly depress the trigger with the palm of your hand so you first hear a slight “hissing”...

    Regulator parts showing wear should be replaced as necessary. Contact your local distributor or Shrinkfast directly for descriptions and part numbers. IMPORTANT SAFETY FEATURE: Inside the POL fitting on the Regulator Assembly there is a safety featured called the “Excess Flow Device”.
  • Page 12 • Once the fuel has filled the entire hose and the regulator gauge reaches 22 PSI, the Excess Flow Device reopens and the heat tool is ready for operation (you will hear an audible “click” from the POL when the pressurization is complete). •...

  • Page 13: Choosing The Correct Propane Tank

    CHOOSING THE CORRECT PROPANE TANK • There are two types of propane tanks commonly available: A. Correct: Vapor withdrawal—Use this style (exactly the same as a BBQ grill tank) B. Not Correct: Liquid withdrawal—Do not use this style (used on fork trucks) WARNING: Using a liquid withdrawal (fork truck) propane tank will clog the orifice in the heat tool and result in an extremely long and dangerous flame.
  • Page 14 CHOOSING THE CORRECT PROPANE TANK (CONTINUED) • Propane tanks are available in a variety of sizes. The most popular tank sizes: • 20 lb. tank similar to a BBQ propane tank for smaller applications. • 40 lb. tanks are commonly used in most industrial applications.

  • Page 15: Tank Pressure, Temperature & Operation

    TANK PRESSURE, TEMPERATURE & OPERATION • Tank pressure depends on the temperature of the tank. At room temperature (72°F) the pressure in a full tank is 110 PSI and drops to 22 PSI at 0°F. If the propane tank ices up during operation: When the heat tool is in operation, the temperature of the tank drops due to the evaporation process of liquid propane to propane gas.
  • Page 16 However, if you are ever in doubt regarding the safety or operation of your heat tool, shut off the tank and contact your authorized Shrinkfast distributor or Shrinkfast directly.

  • Page 17: Ventilation Requirements

    VENTILATION REQUIREMENTS WHEN OPERATING HEAT TOOL WARNING: During operation, the heat tool consumes propane and air and produces carbon dioxide, carbon monoxide (CO), and water vapor. Prolonged exposure to Carbon Monoxide is lethal and adequate ventilation must be provided if the heat tool is to be operated indoors. •...

  • Page 18: General Information On Shrink Film & Shrink Bags

    GENERAL INFORMATION ON SHRINK FILM & SHRINK BAGS Shrink Wrap (#4 LDPE): • The shrink wrap is manufactured in multiple colors and is typically a 6 or 7 mil, low density polyethylene (#4 for recycling purposes). What makes this material different than construction plastic sheeting is that it contains shrinking resins, UV inhibitors, anti-brittling compounds, and strengtheners so that it will not rip or tear.
  • Page 19 want the film cover to reach. Measure up the side, over the top, and down the opposite side to the lowest point. Add one foot to this number to accommodate heat welds and this will indicate how wide your shrink wrap should be. This process will determine the square footage of the object being shrink wrapped.

  • Page 21 Shrink the Bottom of the Pallet First: Shrink Wrapping 1. Ignite the heat tool and hold it approximately 6-8” from the a Pallet Bag: film surface. 2. Move once around the entire pallet applying the heat to the bottom edge of the bag and using the air velocity to blow it under the pallet.
  • Page 22 SHRINK WRAPPING TIPS • During operation, always have the heat tool moving in a side to side motion. The most important fact to keep in mind is that heat only softens the film. The greatest amount of shrinking occurs as the film cools. •...
  • Page 23 PATCHING HOLES IN SHRINK FILM • MISTAKES HAPPEN! Occasionally holes will appear in the shrink film, but they can be easily repaired. Holes in the film can be patched by laying a square piece of shrink film over the hole and applying heat around the edges, thus heat welding the patch to the bag.

    SHRINK WRAPPING LARGE OR ODD SHAPED LOADS • Shrink wrapping is a versatile process that can be employed in a variety of applications. For example, shrink wrappers routinely wrap irregular objects such as industrial equipment. Objects, which are too big to fit under a bag, can be wrapped by using several sheets of shrink film joined together if the following the precautions are observed: •...
