All of us at S.T.E. LLC. Would like to thank you for purchasing one of our pavement marking application systems. 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, which 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 HBM-4 T or M hand applicator.
The HBM-4 applicator is designed to install all types of hot applied thermoplastic road markings, including crosswalks, legends, messages, symbols, center lines, and edge lines.
The HBM-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 many different types of road markings.
This applicator was designed primarily to install hot thermoplastic that has been transferred into the holding tank from a larger premelter. The unit was not designed to melt large quantities of thermoplastic in the holding tank.
The HBM-4 unit by itself has very limited capabilities with regard to melting enough thermoplastic to make it productive in any sense of the term.
This equipment contains a heating system to keep the thermoplastic in the holding tank at operating temperature. An additional radiant gas heating system keeps peripheral components at proper temperatures.
Hot thermoplastic (400-420 deg. F) is transferred by gravity into the HBM-4 holding tank (capacity 250 lbs of molten plastic). The operator then opens a valve by remote lever to transfer the hot thermoplastic, by gravity, into a screed type shaping die. Upon filling the die, the valve is closed and the die is lowered to contact the road surface. A separate remote lever then opens the die allowing the thermoplastic in the die to contact the road. The operator then begins pushing the applicator causing the thermoplastic to be formed on to the road surface. The result marking is based on the width and the height of the opening in the application die being used. Standard dies are 4”, 6”, 8” & 12” in width. Each die is available in a variety of fixed mil thickness, from 0 mil to 250 mil. Application is achieved only when the HBM-4 is moving. The operator then closes the die and raises it from the road surface. surface.
The following text will describe in more detail certain techniques and other related procedures for installing thermoplastic markings with this equipment, including use of the automatic drop-on bead system.
Adjustments for the application die should be made prior to heating the unit. The applicator is equipped with two adjustments for the application dies. To make the adjustments you should start with a clean die in the closed position. Install the die by hooking the die claw onto the torsion spring die retainer located on the front side of the HBM-4 die housing. The die claw should fit between the pins on the retainer shaft. When properly attached the die retainer should be applying down pressure on the die from the torsion springs. Raise the die on the hinge and check for clearance around the material valve.
At this point, with the HBM-4 on the smooth level surface, inspect the clearance of the carbide die runners in relation to the road surface. All four corners of the application die should be contacting the road. If the forward carbides are not contacting, adjust the die retainer down so that they are. Conversely, if the rear carbides are not contacting, adjust the die retainer up. This adjustment can be made by loosening the two 9/16” hex nuts on the ends of the die retainer and sliding the assembly in the slotted bolt holes. After proper adjustment tighten the 9/16” nuts.
NOTE: do not loosen the 3/4" hex nuts on the center stud.
Upon completing the die runner adjustment, connect the linkage to the die using the following steps.
NOTE: if the turnbuckle is adjust ed too long, it will put the die into a bind and cause the molten thermoplastic to leak. Therefore, an adjustment that is slightly short is better that an adjustment that is too long.
NOTE: this keeps the turnbuckle from getting out of adjustment during transport, keep a die installed at all times.
Helpful Hints:
Since road surface relation constantly changes, optimal die runner adjustment provides for 1/64” clearance on the leading carbides. This small gap will help the die glide over projections and variations in the road surface without digging in. However, if the gap is too large the die will not close properly and will create a leaking problem.
If you are having difficulty with the die retainer pivoting from side-to-side, you may need to re-adjust the 3/4” jam nuts on the die retainer pivot stud (center) located on the die shroud of the HBM-4.
Remove the die from the retainer. Using two 3/4” open end wrenches loosen the two nuts and remove one. Tighten the remaining nut to a point where the die retainer can still pivot, but with slight resistance. Re-install the other nut and jam the two together without changing position of the first.
The automatic bead dispenser is infinitely adjustable from 4" width to 12" width. Simply move the 4" lever on the side of the bead dispenser shaft to the desired line width location. The application rate is preset at the factory to 11 lbs. Per 100 sq. Ft. Propulsion speed of the applicator.
Engagement of the bead dispenser is accomplished by raising the die linkage lever to the full vertical position. This action allows the wheel on the bead dispenser to contact the wheel on the applicator. This simple design also incorporates a feature whereby the bead dispenser engagement can be finely adjusted to apply beads with the application die on the road surface in the closed position. This feature allows the operator to continue bead application at the end of the marking.
Hint: in the circumstances when you don't want drop on beads to operate at all simply install a chain to the side of the beader and hook to the wall of the applicator so that the unit does not move down when operating the die lever.
With a new HBM-4 applicator the material valve can be opened and closed freely since no thermoplastic has been introduced to the valve.
Install a clean die that can be opened and closed freely and practice the following steps.
Remember, it takes practice and is easy once you gain confidence.
When performing the above operations with hot thermoplastic, be aware that the marking will remain hot for at least 30 seconds after application. Do not step on the line.
Helpful Hint:
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.
(Note: Actual setting may vary from machine to machine)
The gas line feeding the radiant gas burner system is equipped with one ¼" gas cock valve. That is you're off and on valve. Attached plate show on and off position.
Heat resistant gloves and a suitable face shield must be worn for this operation since back-flashes are commonly associated with lighting burners.
STE-1 dies are very fragile due to the carbide runners and the aluminum constructions. However, the dies will provide a long service life with some basic care and daily maintenance.
STE-1 dies are fixed mil application providing a specific line thickness for a given die. Mil thickness is stamped on the face of the extrusion bar. This is a theoretical application thickness, since thermoplastic is by the laws of physics a product that shrinks upon cooling. Cooling rates can vary dramatically with variations in the thermoplastic formula, ambient temperature and road surface texture.
All STE-1 dies are manufactured with a 10% oversize extrusion gate, I.E. A 100 mil die is cut to .110" depth. It must be noted at this point that thermoplastic under the right conditions can shrink as much as 30% upon cooling.
