Warnings
The following are general warnings related to the safe setup, use, grounding, maintenance and repair of this equip-
ment. In the text of this manual, the exclamation point symbol alerts you to a warning and the hazard symbol refers to
specific risks. Refer back to these General Warnings pages. Additional procedure-specific warnings will be included
where applicable.
Warnings
FIRE AND EXPLOSION HAZARD
Flammable fumes and liquids, such as propane gas, gasoline and combustible fuel, in work area can
ignite or explode. To help prevent fire and explosion:
•
•
Do not use equipment unless fully trained and qualified.
Do not allow open containers of flammables within 25 ft (7.6 m) of equipment. Do not operate equip-
ment within 10 ft (3 m) of any structure, combustible material, or other gas cylinders.
Shut off all burners when adding fuel to equipment.
Close the tank shut-off valve immediately if you smell propane gas; extinguish all open flames. If gas
odor continues, keep away from equipment and immediately call the fire department.
Follow lighting instructions for the burner and torch.
Do not heat thermoplastic traffic marking compound material above 450° F (232° C)
Fire extinguisher equipment shall be present and working.
Keep work area free of debris, including solvent, rags and gasoline.
•
•
•
•
•
•
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•
•
•
Do not leave equipment unattended.
Keep children and animals away from work area.
Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
manufacturer’s replacement parts only.
•
•
•
•
•
Do not alter or modify equipment.
Use equipment only for its intended purpose. Call your Graco distributor for information.
Do not fill material beyond maximum capacity.
Route gas lines, hoses, wires and cables away from traffic areas, sharp edges, moving parts, and hot
surfaces.
•
•
•
Do not kink or overbend gas lines.
Do not override or defeat safety devices.
Do not operate the unit when fatigued or under the influence of drugs or alcohol.
BURN HAZARD
Equipment surfaces and fluid that is heated can become very hot during operation. To avoid severe
burns:
•
•
Do not touch hot fluid or equipment.
Wait until equipment and material has cooled completely.
CARBON MONOXIDE HAZARD
Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Breathing carbon
monoxide can cause death. Do not operate in an enclosed area.

TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swal-
lowed.
•
Read MSDS to know the specific hazards of the materials you are using.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic
fumes, burns, and hearing loss. This equipment includes but is not limited to:

Kettle Temperature Control Calibration
Kettle Temperature Control Calibration
6. If the temperature control setting is lower than the
remote calibrated temperature setting on tempera-
ture probe, turn adjusting screw clockwise. Every
1/4 in. turn will change temperature 35° F (19.4° C).
To Check Kettle Temperature Control Calibration:
™
1. Move Thermolazer to an area with no wind.
2. Turn temperature control to 400° F (204° C).
3. Agitate material for 4 to 5 minutes.
ti14523a
4. After control has reached steady state temperature
and burners do not cycle more than once per min-
ute, insert remote calibrated temperature probe in
material and directly adjacent kettle temperature
control probe.
7. If the temperature control setting is higher than the
remote calibrated temperature probe, turn adjusting
screw counterclockwise--every 1/4 in. turn will
change temperature 35° F (19.4° C).
8. Recheck calibration by turning temperature control
to 410° F (210° C) and repeat steps 3-7.
5. Compare temperature of remote calibrated temper-
ature probe to temperature setting on temperature
control.
Temperature Control Replacement
When replacing temperature control, keep in mind that
the temperature probe is an integral part of the assem-
bly. Do not make any sharp bends in the capillary tubing.
Bends should be 0.25 in. (0.64 cm) in radius or greater.
ti14557a
Be sure to seal capillary tubing with high temperature
mortar at kettle outlet.
Thermometer Replacement
™
Thermometer can not be removed from ThermoLazer
without damaging thermometer probe. If probe end is
frozen in material, heat material and remove until mate-
rial level is lower than thermometer probe.

Securing Bead Dispenser Wheel
Securing Bead Dispenser Wheel
To properly dispense beads, drive wheel (27) must be in
direct contact with tire (89). If drive wheel (27) becomes
loose and/or starts to slip, use allen wrench to tighten
set screw (211).

NOTE: To ensure proper contact between drive wheel
(27) and tire (89), make sure air pressure is always at 60

Linkage Rod Adjustment
Adjustments can be made to linkage rods by removing
clevis cotter hairpin (268), clevis (179) pin, loosening
nuts (128), and then turning clevis as required to
lengthen or shorten rod connectors.
2. If the wheel does not cause the ThermoLazer tire to
rotate both forward and backwards, loosen nuts
(128), clevis cotter hair pin, clevis pin, and rotate the
clevis (179) one turn counterclockwise.
To ensure proper application of beads and thermoplas-
tic, make sure screed box linkage rod (182) measures
16.875 in. (42.8 cm). Be sure to measure where nut
(128) meets clevis (179) when checking for proper link-
age rod length.

Adjust the bead box linkage rod (181) so bead box drive
is touching ThermoLazer tire when screed box is in

Troubleshooting
Applying Material
Problem
Cause
Dirty screed box
Solution
Ragged line edges when extruding
CAREFULLY clean box. Discharge
opening and die plate runners need
to be free of debris.
Cold material temperatures
Marking speed too fast
Heat material as required.
™
Slow Thermolazer speed.
™
Material thickness too think
Slow Thermolazer speed and keep
screed box filled.
Rough material surface when extrud- Overheated material
Reduce heat.

EXAMPLES:
Correct line application will produce a full straight line with sharp edges; correct color,
thickness and width; a firm bond to the surface; and have uniform reflectivity.
