OPERATING INSTRUCTIONS

HEATING THE MATERIAL -1

1. Attach the threaded nipple inlet #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.

OPERATING INSTRUCTIONS

HEATING THE MATERIAL - 1 cont.

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 shutoff 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

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

PUMPING MATERIAL - 2

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
