Important Safety Information

Important Safety Information

If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or death.

Keep gas supply hose away from hot surfaces and flames.

Use only vertical vapor-withdrawal LP gas cylinders which have been designed, fabricated, tested and marked in accordance with registration of the U.S.

Department of Transportation (DOT) or the Standard for

Cylinders, Spheres, and Tubes for the Transportation of

Dangerous Goods CAN/CSA-B337, The Transportable

Pressure Vessels Regulators 2001 (S1 2001/1426), The

Gas Cylinders (Pattern Approval) Regulations 1987 (SI

1987/116)(Pattern Approval Regulations) for EEC-type cylinders (under European Directive 84/525/EEC,

84/526/EEC, and 84/527/EEC. Use only 20 lb to 30 lb

(9.07 kg to 13.6 kg) LP-Gas cylinders.

Use equipment in accordance with state and local ordinances with Storage, Handling and Transportation of

Important Safety Information

Important Safety Information

If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or death.

BEFORE LIGHTING: Smell all around the working area for gas. Be sure to smell next to the ground because propane is heavier than air and will settle on the ground.

DAILY: Check for gas leaks. Use mild soap and water solution or other approved method. Apply solution to all gas lines and fittings then watch for gas bubbles.

ti16842a

Front Screed Box Burners and Rear Screed Box Burners will need to be ignited to test gas lines and fitting downstream of flame adjusting valve.

NOTE: Kettle burners will need to be ignited to test gas lines and fittings downstream of gas safety valves (CC).

Ignite burners and torch only after thoroughly checking gas line and fittings.

WHAT TO DO IF YOU SMELL GAS OR FIND GAS

BUBBLES:

• Evacuate all unqualified personnel from area

• Do not try to ignite any burner

• Do not strike a flame

• Do not use electric fans to remove gas from area

• Do not touch any electric switch and do not use any phone

• If leak is from a gas fitting, tighten fitting until leak stops

• If leak is from a gas line, shut off at LP-gas cylinder and replace gas line

• Immediately call your gas supplier from a remote phone. Follow gas supplier’s instructions.

• If leak can not be stopped by shutting off LP-gas cylinder shut-off valve, immediately call your gas supplier from a remote phone. Follow gas supplier’s instructions.

• If you cannot reach your gas supplier call the fire department

3A1319C ti16832a ti14128a

Use only your hand to push in or turn the kettle gas safety valve (CC). Never use tools. If the knob will not push in or turn by hand, do not try to repair it; call a qualified service technician. Attempted repair or force may result in a fire or explosion.

Do not use this equipment if any part has been under water. Immediately call a qualified service technician to inspect equipment and all components. Replace defective parts only with approved manufactured parts.

Important Safety Information

Important Safety Information

Before attempting to start equipment:

If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or death.

All surfaces are capable of becoming extremely hot.

Be sure to always wear heat-resistant gloves and other protective equipment rated for 500° F (260° C).

Secure ThermoLazer

by chocking wheels.

ti14603a

2.

Use scraper to clean out trough and screed box.

NOTICE

Be sure to thoroughly clean all material out of screed box and any open areas to prevent material from freezing moving parts of screed box. Always run all material out of each screed box before removing. Scrape out all remaining material before it sets within the screed box.

NOTICE

To prevent material from hardening and blocking flow, scrape all excess material off of external surfaces after each use, including the material trough.

NOTICE

Remove any remaining beads in the bead hopper and bead dispenser to prevent beads from clogging hopper and dispenser.

Transporting

Remove LP-Gas supply cylinder from ThermoLazer

™ before transporting. Secure in an approved location and method as authorized by local, state, federal, national, and international agencies.

Always use the designated mounted lifting lugs when lifting the Thermolazer

. When lifting the Thermolazer

5.

Open material gate and pour out remaining material in a heat-resistant container.

6.

Turn kettle burners OFF.

7.

Use long-handled scraper tool (VV) to remove material from inside of kettle. Start by scraping from the top of the kettle sides and work your way down so that as soon as the material collecting at the bottom begins to cool and harden you can scoop it out of the kettle. Collect material in a heat-resistant pan.

NOTE: If material becomes too hard to scrape or remove, reheat the kettle until the material becomes soft again.

NOTICE

Remove any remaining beads in the bead hopper and bead dispenser to prevent beads from clogging hopper and dispenser.

Transporting

Remove LP-Gas supply cylinder from the unit before transporting. Secure in an approved location and method as authorized by local, state, federal, national, and international agencies.

Always use the designated mounted lifting rings when lifting the unit. When lifting the unit, only use ANSI approved slings and equipment rated for a minimum of

2000 lb. Always use ANSI approved equipment for securing the unit to transporting equipment.
