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.

OPERATING INSTRUCTIONS
3-START TO PUMP MATERIAL
1. Attached to the regulator/water trap filter A5 is the pump air
control valve A6, it regulates the volume of air that goes to the
material pump A7 and the volume / GPM of material flow.
The regulator’s factory setting is 80 psi. It controls the spray
pressure of the material pump A7.
2. It is only necessary to open the pump air control valve A6 part
way –1/4 to 1/2 is adequate.
3. NOTE: Opening all the way, will cause the material pump A7 to
consume more air than the compressor can produce, which will
cause the air pressure to drop.

4-START THE SPRAY WAND
1. Open material hose feed valve M1 to pressurize the hose, then
the spray wand valve M6. To start spraying. Hold the wand at
waist level and walk at a steady pass lapping each pass 50%.
2. The thickness of the material determines how much pressure is
needed to properly atomize the material, only use enough
pressure to atomize the material. This will reduce overspray.
3. Adjust the pressure setting on regulator/water trap A5 to get a
proper spray pattern. To do this, turn the knob on top of the
regulator in for more or out for less pressure. When the material
is coming out of the spray tip 80/70 P30, you will feel the wand
push up.

OPERATING INSTRUCTIONS
5-WATER FLUSH
1. It is not necessary to flush the system every day. We suggest
removing the spray tip and plugging the wand, when not in use or
transporting from job to job.
2. If the machine is going to be out of service for a week or more,
then water flush the system.
3. If outfitted with the water option, close main tank valve M5 and
open the small water flush valve M3 that is on the basket strainer
M2.
4. Open pump air control valve A6 and your spray wand valve M6.
Pump until water runs clear.
5. On basket strainer M2 is a water check valve P10, this helps keep
sealer from flowing into the water tank if you leave the valve
open. Do not rely on this check valve, always close the water flush
valve M3.
6. If you do not have the water option, close main tank valve M5.
Remove the lid assembly from the basket strainer M2.
7. Open pump air control valve A6 and pour water into the basket
strainer M2, as it is being pumped to the spray wand.
Note: Skid tank configuration is different from the trailer, but the
operation is the same.
