SAFETY

Read these instructions thoroughly to familiarize yourself with the parts and safe operation of this tool. Keep for future reference.

• Never point the gun at another person.
• Inspect hose before each use.
  • Always shut off valve at tank when leaving gun unattended for any length of time.

• Safety trigger mechanism automatically shuts off if gun is dropped.

• Wear heat-resistant gloves and safety glasses when using the gun.

GENERAL INFORMATION

SHRINK FILM

Use only with shrink film (not all plastic films are shrink film). Shrink film should be virgin plastic, not reprocessed material. For light loads of 100 lbs. or less, 3 mil thick film should work. For heavy weights or items (example, steel drums at 2,000 lbs./pallet), use 6 mil or thicker shrink film.

• Gusseted film shrinks equally in both directions, and tends to pull up and away from pallet. Length should be longer than the height of the pallet.
• Centerfold film shrinks mainly in one direction and has a reduced tendency to pull up off of pallet.

SHRINK BAG

Most bags list lay-flat length and width. To determine what size bag you need, use the following example:

Load size: 47 x 30 x 36" (L x W x H)

Calculate the width of bag:

1. Add the width and length 30 + 47" = 77"
2. Add fitting allowance (4" to allow for ease of fit) 4 + 77" = 81" (This is the width bag you'll need.)

Calculate the length of the bag:

1. Use 1/2 the length of the shorter side 1/2 of 30" = 15"
2. Add number from step 1 to height 15 + 36" = 51"
3. Add shrink allowance (1" for each foot of height) 36" = 3', so 3" shrink allowance 51 + 3" = 54" (This is the length bag you'll need.)
4. Bag size is 54 x 81" (L x W).

PROPANE TANK

WARNING! Use only with vapor withdrawal propane tanks. NEVER attach heat gun to a liquid withdrawal propane tank.

WARNING! Using a liquid withdrawal propane tank clogs the orifice filter and may result in an extremely dangerous long flame.

Tanks are available in 6, 8, 10, 20, 30 and 40 lb. sizes. 6 lb. tanks are adequate for intermittent use. Use larger tanks for continuous use.

Tank Pressure – Depends on tank temperature. At 72^ F, pressure is 110 psi; at 0^ F, pressure drops to 22 psi. When in use, tank pressure drops due to evaporation process of converting liquid propane to propane gas. Tank may drop to 0^ F with ice appearing on the outside. Propane pressure may drop below 15 psi.

WARNING! DO NOT run the gun when tank pressure drops below 15 psi.

• For continuous operation, use multiple tanks, switching the gun from one to another.
• Using an ordinary desk fan to blow air on the tank will prevent it from icing up.

VENTILATION

When in use, this heat gun produces carbon dioxide, carbon monoxide and water vapor.

WARNING! Prolonged exposure to carbon monoxide (CO) is lethal. Provide adequate ventilation when gun is used indoors.

To maintain a safe CO concentration (50 parts per million as set by OSHA Standard 1910.93), ventilation requirements are 2,000 cu. ft./min. of fresh air while gun is operated at maximum operating pressure of 30 psi.

Ventilation capacity should be sized proportionally for different production rates.

EXAMPLE: Based on a 1½ minute heating cycle per pallet, fresh air requirements are 3,000 cu. ft./pallet. If the production rate is 10 pallets/hour, a ventilation system needs to provide 500 cu. ft./minute.

In areas where ventilation is provided by open doors or windows, safe CO levels will be maintained as long as room temperature does not exceed 150^ F.

CONNECTIONS

1. Connect gun, hose and regulator to the tank. Use a wrench to tighten fittings (left-hand threaded). (See Figure 1)

2. Check for leaks.

3. Open tank valve without pushing trigger to pressurize the hose. Pressure gauge should read 15 to 30 psi when gun is not in use.

4. Close tank valve and check pressure gauge. Rapid pressure loss indicates a leak. Check all connections.

OPERATION CONTINUED

START-UP

Open the tank valve and wait 5 seconds to fully pressurize hose. You will hear the flow check valve open with an audible click.

1. Press the safety trigger. This prevents the gas handle from opening accidentally. (See Figure 2)

Figure 2 Safety Trigger Hand Trigger (Gas Handle)

1. Slowly squeeze the gas handle until the igniter fires with an audible click. (See Figure 2)

CAUTION! Gun will ignite.

IMPORTANT:

• Squeezing the gas handle too quickly will cause the igniter to fire the spark plug before the gas mixture is ready.
• If gun fails to fire fully, release BOTH the safety trigger and gas handle to reset the igniter. Then repeat the starting procedure.
• For thinner films, set the regulator for lower pressure and adjust up for thicker films. Factory preset is 22 psi.

USING THE HEAT GUN

Use gun only in well-ventilated areas.

WARNING! Do not operate gun in areas with flammable gases or where smoking is prohibited.

IMPORTANT HEAT SHRINK TIPS:

• Heat only softens film. Shrinking occurs as film cools. Do not concentrate heat and wait for film to shrink. Keep the gun moving.
• Ensure the four corners of the bag are wrapped under pallet.

PALLETIZING

1. Elevate pallet load approximately 6" from floor. Leave area under the four corners clear.
2. Carefully fit pallet bag over load. Do not puncture or tear the bag. Bag should fit snugly over the load and overlap the base of the pallet almost to the floor.

3. Shrink Bottom: Ignite gun and hold about 12" from film.
   a. Move around pallet, applying heat to the bottom edge of the bag and blow it under the pallet.
   b. Shrink film to grip bottom of pallet firmly, locking bag to pallet and unitizing load.

4. Shrink Sides: Do one side at a time.

a. Holding gun 12" from film, shrink side by sweeping gun smoothly across the bottom edge.
b. Move up one foot and sweep back, continue to move up and sweep across the side until you reach the top.

IMPORTANT! Keep gun moving at all times.

c. Repeat for the remaining sides.

1. Shrink Top: Since top is already pulled taut by the four sides being shrunk, this requires less heat than shrinking the sides.

PATCHING

Patch holes easily: Lay a square of film over the hole and apply heat to the edges to weld patch to bag. Also useful for reinforcing edges or corners.

SHRINK WRAPPING LARGE OR ODD-SHAPED LOADS

Wrap objects too big to fit under a bag by joining several sheets of shrink film together.

1. Adjoining sheets should overlap 18".
2. Secure sheets using the weight of the load at the base or with battens tacked to the skids.

TROUBLESHOOTING

NOTE: Check tank first – Majority of problems are caused by using a liquid withdrawal tank instead of a vapor withdrawal tank.

OPERATING ISSUE CAUSES RECOMMENDATIONS
Gun will not fire.	Handle not fully depressed.Handle depressed too quickly.Pressure too low.Handle not released fully.Spark plug needs to be replaced.Gas not turned on.	Depress handle all the way until the igniter fires. Listen for a click.Slowly squeeze handle to ensure mixture enters combustor before firing.Check regulator.Release handle and safety triggers to reset igniter.Replace spark plug using the instructions included.Check On/Off valve.
Combustor turns red.*(insufficient fuel flow)	Wrong fuel.Tank used up and tank pressure is below 15 PSIG.Excess flow check valve not open.Clogged orifice and/or filter.Clogged hose.Clogged fuel line.	Check fuel type.Switch to new tank.Open tank valve and wait 10 seconds until hose is pressurized before using gun.Remove and clean with compressed air.Blow or replace.Blow out or replace.
Large flame-fuel flow.	Leak in orifice assembly.Wrong pressure.	Tighten orifice in holder and check.Reset to 15-30 PSIG.

* Leading edge of combustor turns red under normal conditions. More than 1" of combustor turning red indicates trouble.
