Warnings
Warnings
The following are general warnings related to the safe setup, use, grounding, maintenance and repair of this equipment. 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 equipment 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.

Warnings
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 swallowed.
• 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:
• Clothing and respirator as recommended by the fluid, material, and solvent manufacturer.
• Gloves, shoes, overalls, face shield, hat, etc. rated for elevated temperatures of at least 500° F
(260° C).

Kettle Gas Safety Valve, Kettle Temperature Control, and Kettle Thermopile Diagnosis
Kettle Gas Safety Valve,
Kettle Temperature Control, and
Kettle Thermopile Diagnosis
The gas safety valve, temperature control and thermopile can be checked by using a millivolt meter. Before
checking, make certain all electrical connections are
clean and tight.
Connect millivolt meter to appropriate terminals (see
Terminal Connections).

If mV reading < 100mV, proceed with diagnostic steps 2
and 3.
If reading > 80 mV:
• Clean and tighten electrical connections at temperature control and gas safety valve.
• Check valve to make sure wires are in good condition. Replace as required.
• Rapidly change temperature setting on temperature
control to see if cycling cleans the contacts.

If mV reading < 325 mV:
• Clean and tighten all electrical connections.
• Adjust pilot burner to increase millivolt output (see
page 11).
If the preceding fails to give mV reading > 325 mV, replace
thermopile.
Check valve magnet after obtaining correct mV output for
thermopile:
• Ignite pilot burner only and allow the mV reading to
stabilize.
• Shut pilot burner (turn gas safety valve knob OFF).
Note the mV reading where magnet drops out.
If magnet unlocks at mV reading < 120 mV, the magnet is
OK. NOTE: When magnet unlocks a click can be heard
and mV reading may fluctuate slightly.

Kettle Temperature Control Calibration
Kettle Temperature Control Calibration
6. If the temperature control setting is lower than the
remote calibrated temperature setting on temperature 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
2. Turn temperature control to 400° F (204° C).
3. Agitate material for 4 to 5 minutes.
4. After control has reached steady state temperature
and burners do not cycle more than once per minute, insert remote calibrated temperature probe in
material and directly adjacent kettle temperature
control probe.
5. Compare temperature of remote calibrated temperature probe to temperature setting on temperature
control.
™
to an area with no wind.
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.
Temperature Control Replacement
ti14523a
When replacing temperature control, keep in mind that
the temperature probe is an integral part of the assembly. 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 material 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
psi (4.14 bar).
Linkage Rod Adjustment
89
27
211
ti14564a
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.
To ensure proper application of beads and thermoplastic, 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 linkage rod length.
16.875 in.
182
Adjust the bead box linkage rod (181) so bead box drive
is touching ThermoLazer tire when screed box is in
down (but not open) position. A slight downward force
on the bead box linkage should be required when inserting the clevis pin through the clevis deployment bar.
ti14565a
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.
179
128
3. Reconnect clevis to deployment bar and again
rotate bead box wheel to see if adjustments cause
ThermoLazer to move forward and backwards.
4. Continue to rotate clevis 1/2 turn counterclockwise
until rotating bead box wheel causes ThermoLazer
to move forward and backwards.
1. With screed box in down (but not open) position,
rotate the bead box wheel by hand.

Screed Box/Bead Dispenser Box Actuator
If the screed box/bead dispenser box actuator does not

Adjusting Screed Box Pivot Arm
If the SmartDie™ screed box jumps up when setting the
box in the down-and-locked position, check linkage rod
lengths (see page 14).
If the SmartDie
™
screed box continues to jump up after
adjusting linkage rods, move the screed box pivot arm
spring to the next hole.
1. Unhook top of box pivot arm spring.
ti14627a
2. Unhook bottom of box pivot arm spring.
3. Move bottom of box pivot arm spring to desired hole
and reconnect. Moving the spring in will decrease
tension, while moving the spring out will increase
tension.

4. Reconnect top of box pivot arm spring.
ti14630a
Repeat moving pivot arm spring until SmartDie
