All of us at S.T.E. LLC Would like to thank you for purchasing one of our Bitumen Applicators. We hope you will appreciate our effort in making this unit as user friendly as possible. We have spent a great deal of time engineering the system to provide the end user with a highly productive tool that will give years of safe reliable operation. Please read this manual carefully and give your unit the care as outlined in the following pages and the system will respond accordingly.

This manual will provide you with the necessary information to operate and maintain your HBT-4 T or M hand applicator.

The HBT-4 applicator is designed primarily to install hot bitumen material to place reflectors or fill cracks. By design it can be used either left or right handed. The unit by itself has the capability of melting enough bitumen to make it a productive tool.

The HBT-4 has been engineered to meet the ridged demands of the contracting industry, and with a small amount of care and maintenance it will provide years of service with minimal repairs.

The construction of this applicator is primarily lightweight aluminum, and is balanced to enable the operator to maneuver the unit with minimal effort. This maneuverability enables the operator to make very sharp turns and ultimately provides a great deal of flexibility to install reflectors or fill cracks. A removable aluminum basket is provided to hold reflectors.

This equipment contains a heating system to heat and keep the bitumen in the holding tank at operating temperature. A thermometer is installed on the top, in view of the operator, for easier material temperature control.

Thanks Again

Basic Principal of Operation

Hot bituminous material (400-425°F) is held in the holding tank (capacity 250lbs.) the operator then opens a valve by remote lever to transfer the hot bituminous material, by gravity, to the road surface or the crack to be filled. The operator then closes the valve and goes to the next crack or pushes the applicator ahead and sets the reflector in place.

Caution: do not heat above 435°F.

Getting started

Get comfortable & become familiar with the entire unit.

Lighting the applicator

Thermostatically Controlled Applicator

Main burner: NEVER NEVER use a torch to light burners

  1. Connect a 20lb fuel tank to the pol fitting on the gas hose regulator.
    (the pol fitting has left hand threads)
  2. Check to see that all valves are in the off position. Do not adjust the regulator; it is preset at the factory.
  3. Turn on tank fuel valve by rotating counter clockwise.
  4. Immediately check for audible leaks. Check further for other leaks by wetting fittings with a soap and water solution, looking for bubbles.
  5. Check thermostat and set to lowest setting (counter-clockwise).
  6. Access the pilot through the front firebox door on the HBT-4T. Use the push button igniter to light the main burner pilot. If push button fails you can ignite the main burner pilot using a long bar-b-que flame type lighter.
    NEVER NEVER use a torch
  7. Hold red pilot safety button in while trying to ignite the pilot. This process may take several minutes in order to allow air in the lines to bleed out.
  8. Upon successfully igniting the pilot continue to hold the red pilot button for 30 seconds or until the pilot remains lighted when releasing the button.
  9. Adjust the thermostat to the desired temperature and check to see that the main burner has lighted.
  10. Constantly monitor the material temperature and double check with an infra-red thermometer.
  11. Never leave the lighted applicator unattended.
  12. Do not allow the burner to operate with an empty material tank.

Helpful Hints: Monitor the burner flame to see if it shuts down prior to the material reaching proper operating temperature. This phenomenon is not uncommon and occurs due to the fact that the sensing probe is installed on the tank wall where the temperature is higher than the material temperature especially during start-up. Adjust the thermostat to compensate for this deviation. But keep in mind that under this circumstance the burner may not cycle down at the proper temperature. When the desired material temperature is achieved, re-adjust the thermostat until the burner flame goes out. No further adjustment on the thermostat should be required.

Manually Controlled Applicator

Main burner NEVER NEVER use a torch to light burners

  1. Connect a 20lb. Fuel tank to the pol fitting on the gas hose regulator.
    (the pol fitting has left hand threads)
  2. Check to see that all valves are in the off position. Do not adjust the regulator it is preset at the factory.
  3. Turn on tank fuel valve by rotating counter-clockwise.
  4. Immediately check for audible leaks. Check further for other leaks by wetting fittings with a soap and water solution, looking for bubbles.
  5. Access the main burner through the front firebox door. First turn the main burner fuel valve on slightly then push the remote push button igniter. Next turn the main burner fuel valve on slightly until the burner ignites.
    1. If the igniter fails to light the burner you can Use a long bar-b-que flame type lighter (first light the lighter then place it in position to light the main burner).
    Now set the flame to the desired height. Next close and latch the burner access door.

Heat resistant gloves and a suitable face shield must be worn for this operation since back-flashes are commonly associated with lighting burners.

After Successfully Lighting the HBT-4 Follow These Steps:

  1. Check to see that the HBT-4 material valve is completely closed.
  2. Introduce only the amount of bituminous into the HBT-4 you intend to use.
  3. When using the HBT-4 to melt bitumen be patient. Wait for the product to reach 400 - 425°F. Before attempting to continue.
  4. Never over fill the applicator and keep the top of the HBT-4 scraped clean of spilled material.
  5. After filling always close and latch the material tank doors.
  6. Agitate your material often. Bitumen does not need to be agitated under (300°F) however, agitation requirements begin at 325°F. and increase in frequency to about every 5 minutes at 420°F.
  7. Always use the hot bitumen in this equipment within 30 minutes or drain and recycle it.
  8. Never allow this unit to cool with a full tank of material. Try to drain as much bitumen from the tank as possible prior to shutting down. It is also a good idea to clean out the material pipe with a piece of hydraulic hose or other suitable material.
  9. Never leave the flame on with an empty material tank. It is under this circumstance that overheating and material flash is most possible.

Shut down, cleaning, and maintenance

  1. With the days work completed, turn off the tank valve then turn off all other valves. Do not adjust the regulators.
  2. Check your gas supply for the following days work. Always keep a spare tank of gas available.
  3. Completely drain the HBT-4 and scrape top sides clean of any spillage.
  4. Lubricate the axle bearings every 40 hours of operation with high temperature grease. This equipment produces very little load or speed demands on the bearings, so it is important to understand the theory of lubrication. The grease simply acts as a filter within the bearing housing to keep foreign matter from contacting the bearing surfaces. Excess amounts of grease simply attracts and collects foreign matter. Therefore a small shot of grease daily to push out any possible contamination is better than heavy lubrication weekly.
  5. Frequently scrape the inside of the material tank while it is hot to prevent any build up of resins in areas where the agitator does not contact the tank wall.
  6. Cleanliness is the #1 maintenance item on the HBT-4 M/T applicator.
Always remember: whenever you are performing tasks that involve hot equipment, wear your gloves and protective clothing.
