STARTUP
STARTING THE ENGINE
NOTE: If equipped with optional hydraulic drive upgrade refer to pages 18-26
•Set the fuel shutoff and choke levers to the on position.
•Set the throttle lever at ½ open.
•Set the engine on/off switch to on position.
•Pull start the engine.
•It is important that when you are done running the engine that the
fuel shutoff lever is turned to the off position. This keeps gasoline from
mixing with oil as you are driving.
Refer to the engine manual.

OPERATING INSTRUCTIONS
HEATING THE MATERIAL
1. Attach Nut & Nipple #1 to your LP Gas tank.
The burner uses vapor propane, NOT liquid.
2. Slowly open the valve on the LP Gas Tank. Opening too fast can cause a check valve to
slam closed, reducing the available flow of gas.
3. Regulator #3 is pre-set for 30 psi. Turn the knob counter-clockwise to lower the
pressure. The burner #11, is rated for maximum heat output at 30 psi. Open gas shut-off
valve #7 slightly, depress the red push on gas pilot valve #8. This allows gas to flow thru
the burner, at the same time use the striker flint #10 to produce a spark.
Strike repeatedly until the gas ignites.
If the gas does not light within 5 seconds, release the red push button
and wait 10 minutes before trying again.
Once you have ignition, you must continue to depress the red push button on gas pilot valve
#8 for at least 10 seconds. This allows the thermocouple #9 to heat up, allowing the gas valve
to continue the gas flow. If the flame stays on, then open gas shut-off valve #7 all the way to
get maximum heat from the burner.
If the flame goes out, you will need to start over with the lighting process.
Anytime you want to decrease the flame intensity, slightly close gas shut-off valve #7.
4. The thermocouple #9 also acts as a safety. Should the flame go out because of wind, the
thermocouple immediately starts to cool off and stops the signal to the gas valve, which
then stops the flow of gas. This may take up to 30 seconds.
WAIT 10 MINUTES BEFORE TRYING TO RE-LIGHT THE BURNER.
5. Monitor material temperature on thermometer #13. As the material reaches the
desired temperature you can slightly close gas shut-off valve #7 to decrease the flame,
or just shut off the valve completely.
NEVER DRIVE WITH THE BURNER LIT!!

OPERATING INSTRUCTIONS
PUMPING MATERIAL
6. Open main tank valve #16 and recirculation valve #24. Close all other valves.
7. Start engine #23 only after reading the engine manual, provided with your
machine. Engine speed will determine the gallons per minute pumped.
8. Start by recirculating material. The material pump #22 draws material from
the tank, thru the basket strainer #17, thru the recirculation valve #24 and
into the top of the tank.
9. Uncoil the spray hose from the side hangars on the tank. Open spray hose
feed valve #25 and spray wand valve #27. Slowly start to close recirculation
valve #24. This will send some product down the spray hose and out the
wand spray tip 80/20 #28. Partially closing this valve allows you to adjust the
desired spray pressure.
NEVER CLOSE RECIRCULATION VALVE #24 COMPLETELY
SPRAY BAR
10. When using the spray bar #31, spray hose feed valve #25 and spray wand
valve #27 remain closed. Once you have recirculated product, slowly close
recirculation valve #24. Open spray tip valves #32 on the spray bar #31.
Position the machine, motion for the driver to start forward at approx. 4mph,
open spray bar feed valve #38,and also the #55 spray bar lever, to start
spraying. This opens all of the spray tip valves #32 at the same time. Once
again, recirculation valve #24 determines spray pressure, adjust accordingly.
11. The throttle on the engine #23 needs to be set to 3/4 or full position to
ensure there is enough speed is available for the material pump #22.
12. Run the pump pressure and speed at the lowest acceptable application
pressure to help reduce overspray.
13. You can control pressure by using the recirculation valve #24.

10
14. Close spray bar feed valve #38 or the #55 spray bar lever when you reach the
end of your pass, leave all the pump controls set. The spray will continue
when you open the spray bar feed valve #38 or the #55 spray bar lever.
15. Position the tires right next to the previous pass, this will give you the proper
overlap.
16. When finished, turn off the engine and close all valves and follow flushing
instructions below.
DIESEL FLUSH
17. Close main tank valve #16 and recirculation valve #24. Start engine #23.
18. Open diesel flush valve #15 on the bottom of the diesel tank #12.
19. Open spray hose feed valve #25 and spray wand valve #27 to flush the spray
hose and wand. To flush the spray bar open spray bar feed valve #38 or the
#55 spray bar lever on the spray bar #31 to the open position. When done,
turn off the engine and close all open valves.
20. Use only diesel fuel for flushing purposes.
21. Remove the lid from the basket strainer #17 and clean the basket.
Anytime you notice the spray pressure is decreasing, the
basket strainer #17 probably needs to be cleaned. Make sure you close main
tank valve #16 before you remove the lid.
MAINTENANCE TIPS
22. Adjust the V-belt #20 tension, by going halfway between the center of the
two pulleys and moving the belt up and down. It should move about ½”.
23. The material pump #22 has a mechanical seal, some leakage is normal. When
the seal plate cannot be tightened any more, the seal must be replaced.
24. The orifice is inside burner #11, needs to be cleaned occasionally. Soot and
spider webs can cause blockage of the flow of gas.
25. Always leave the LP gas hose #6 connected to a tank. If left
disconnected, insects will make their nest inside of it and block the flow of
gas.
