  • Page 4: General Safety Precautions & Safety Certification

    GENERAL SAFETY PRECAUTIONS - READ ALL INSTRUCTIONS BEFORE OPERATING THIS HEAT TOOL • This heat tool can only be used with vapor withdrawal propane tanks (BBQ Grill Style) and should never be used with liquid withdrawal tanks (Fork Truck Style). See Page 11 of this User’s Manual for additional information on the proper tank style.
  • Page 5 GENERAL SAFETY PRECAUTIONS • When working with any type of heat or open flame, always keep a fire extinguisher close by. • Always were 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. If the air flow is reduced the heat tool will not work properly.
  • Page 6 Once heat is applied to the shrink film, it will continue to shrink even after the heat is moved away from the area. • Never modify the tool in any way and use only Shrinkfast replacement parts. • Never operate in a basement or closed in, non-ventilated area or on an area that you cannot see.

    REGULATOR OPERATION & MAINTENANCE Adjustable Hand Wheel 0-2.0 bar Pressure Gauge – Adjusts bar Setting of the Regulator POL – Attaches to Hose Adapter – Attaches the Propane Tank to the Supplied 7.62 meter Hose Regulator Technical Overview: • The MEGR-6120 is a high capacity, bar to bar, 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 1.4 bar and 2.0 bar. 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 1.5 bar.
  • Page 9 2.Connect one end of the supplied 7.62 meter 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.

  • Page 10: Starting The Heat Tool

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

  • Page 11: Regulator Maintenance & Safety Features

    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 1.5 bar, 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: • 9.07 kg tank similar to a BBQ propane tank for smaller applications. • 18.14 kg tanks are commonly used in most industrial applications. The weights listed on the above tanks are in lbs.

  • Page 15: Tank Pressure, Temperature & Operation

    Temperature of Propane TANK PRESSURE, TEMPERATURE & OPERATION • Tank pressure depends on the temperature of the tank. At room temperature (22.22º C the pressure in a full tank is 7.58 bar and drops to 1.5 bar at -17.77º C. ) Propane Temperature (degree C) A pressure relief valve vents propane vapor whenever the tank pressure exceeds 17.23 bar and prevents excess tank pressure.
  • 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 20: Shrink Wrapping Techniques (Pallet Bags & Odd Shaped Objects)

    MEASURING FOR A SHRINK PALLET BAG 1) Measure the length, width and height of the pallet to be covered. 2) Determine the length (L) of the bag, by adding 5.08 cm to the length of the pallet. 3) Determine the Width (W) of the bag, by adding 5.08 cm to the width of the pallet.
  • Page 21 Shrink the Bottom of the Pallet First: Shrink Wrapping 1. Ignite the heat tool and hold it approximately 15 - 20 cm from a Pallet Bag: the 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.
  • Page 24 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: •...
