STARTUP
WARNING
To reduce the risk of serious bodily injury, including
injury from moving parts or electric shock, always
follow this procedure whenever you shut of f the
system, when checking or servicing any part of the
system, and whenever you stop dispensing.
1. Turn the ON/OFF switch to OFF.
2. Unplug the power supply cord.
3. Trigger the spray valve to relieve pressure.
If you suspect that pressure is not fully relieved af-
ter following the steps above, open the priming
valve 2 turns counterclockwise.
1. Place the suction tube in the pail of material.
2. Plug in the sprayer.
3. Open the priming valve 2 turns
counterclockwise,
which drains the material into the pail through the
priming tube.
4. Turn the ON/OFF switch ON.
5. As soon as you see material flow through the priming
tube, close the priming valve
(clockwise). Priming
usually takes less than 30 seconds.
CAUTION
Failure to completely close the priming valve after
the system is primed will cause the valve to erode,
greatly shortening the valve life.
6.
If your system is hard to prime,
force feed the suc-
tion tube. Hold the suction tube in a vertical position
and pour material into it. Turn on the system. If the
system does not prime within one minute, shut it off.
7.
If the system still does not start,
push the inlet
open with a pencil eraser, and try priming the system
again.
NOTE:
Heavy viscosity material may need to be
thinned. Be sure to follow the material manufac-
turer’s recommendations on thinning.
6. When the outlet hose is fully primed, the motor runs
when there is material demand, but appears to shut
itself off when there is no material demand.
NOTE:
An occasional start and stop of the motor when
the spray valve is off is normal.
OPERATION
To reduce the risk of electric shock, do not expose
the system to rain. Always store the
system
indoors.
WARNING
CAUTION
Always allow cold equipment to warm to room tem-
perature before using to prevent damaging the sys-
tem. Always store the system indoors.
1. With the system fully primed, trigger the spray valve
until an even flow of material is spraying out of the tip.
2. Hold the spray tip approximately 12 in. (300 mm)
from the surface and start spraying.
3.
For low pressure spraying
, use the tip supplied
with the wand. This tip develops a spray pattern at a
very low pressure when spraying fluids about the vis-
cosity of water, such as wetting agents, penetrating
encapsulants and lock-downs.
4.
For fine-finish spraying,
use the fine-finish tip
which produces a fine mist for “glove-bag” applica-
tions.
5. Whenever you are done spraying, turn the switch to
OFF and trigger the spray valve.
6. Flush the system thoroughly and immediately after
each use to keep it in good working order. See page
6.
