1. Remove all packaging materials, tape, and plastic coverings from your towable Trail Boss Unit.
2. Remove the 30 lb. cylinders and take to an authorized propane dealer for purging and filling.
3. Place one bag of lava rocks over burners in each section prior to igniting.
4. We recommend curing your grates by applying a coating of vegetable oil to the grates, then heating the grates for approximately 20 minutes prior to cooking the first time.

1. These Big John Products are designed for OUTDOOR USE ONLY.
2. Park the Trail Boss on a level area clear of combustible materials.
3. Securely connect regulator to propane cylinder(s) and test for leaks according to the instructions in the PROPANE SAFETY section of these instructions.
4. Cylinders should always be turned off and have safety plugs installed when transporting or not in use.

Operation

1. These Big John products are designed FOR OUTDOOR USE ONLY.
2. Securely connect regulator to propane cylinder(s) and test for leaks according to the instructions in the PROPANE SAFETY section of these instructions.
3. Cylinders should always be turned off and have safety plugs installed when transporting or not in use.
4. Prior to opening main cylinder valve, and lighting grill, place all control knobs in the "CLOSED" position (turned to the left).
5. Open main cylinder valve. Hold a lit butane gun next to a burner and turn the burner control knob to "OPEN" (pointing at you). The burner will ignite instantly. The second burner in each section will instantly light by simply turning it on. Since each section is ignited separately, only light the sections required.
6. Once burners are lit, adjust the control knobs to desired temperature.
7. When finished cooking close all control knobs, close the main cylinder valve and disconnect propane cylinder from the grill. Store and transport the cylinders according to the instructions in the Propane Safety section of this manual.
8. Cast Iron Grates must be protected from moisture and stored with a coating of vegetable oil to prevent rusting.

1. The Trail Boss requires you to use a 2" ball. The latch must be down and secured. Safety chains are included and must be used.
2. Check with your State Department of Transportation concerning the licensing of the trailer.
3. We recommend that the Trail Boss be repainted periodically. A fresh coat of paint not only enhances the trailers' appearance but improves its longevity.

• Never use or store cylinders indoors.
• Keep main cylinder valve securely closed when not in use. WARNING: Propane tank valves are designed to work completely open and/or completely closed. Never just crack the valve.
• Always position the LP cylinder so that the connection between the valves and the regulator will not cause sharp bends in the hose.
• The POL connector on the regulator screws in to the valve outlet of a 30 lb. cylinder, by turning counterclockwise (to the left) only.
• Make sure the connector is free from scratches or nicks which can cause leaks.
• There are two (2) types of connectors (see Diagram A and Diagram B)
• DISCONNECTING AND TRANSPORTING CYLINDERS FOR REFILLING:
  1. Turn off all control knobs and close the main cylinder valve.
  2. Place cylinder plug snugly in the main cylinder valve outlet.
  3. Always transport and store LP cylinders in a secured, upright position.
  4. Never keep propane cylinders in a hot car or truck. Heat could cause the relief valve to discharge propane and create a dangerous situation.
• RECONNECTING A FILLED 30 lb. CYLINDER:
  • Remove the main cylinder valve plug.
  • Thread the POL Connector snugly into the main cylinder valve by turning counterclockwise (to the left).
  • What you do next depends on whether you have a soft nose connector with a rubber ring or a hard nose connector:
• WITH A SOFTNOSE CONNECTOR (DIAGRAM A):
  If there is a hand wheel, tighten firmly by hand, or use a wrench. DO NOT OVERTIGHTEN. The rubber O ring must be in place on soft nose POL connectors, otherwise it may not seat and form a good seal.
• WITH A HARDNOSE CONNECTOR (DIAGRAM B):
  Use 8" adjustable wrench. Tighten firmly but do not use excessive force.
• Always test for leaks according to the diagram below.
• If you suspect a problem, have your grill or tank serviced by a qualified propane dealer.
