WARNING
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
injury from moving parts, or electric shock, always
follow this procedure whenever you shut off the sys-
tem, when checking or servicing any part of the sys-
tem 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 after
following the steps above, open the priming valve 2
turns counterclockwise.
1. Place the suction hose in the pail of material.
2. Plug in the sprayer.
3. Open the priming valve 2 turns counterclockwise.
4. Turn the ON/OFF switch ON.
WARNING
To reduce the risk of electric shock, do not expose
the system to rain. Always store the system indoors.
Do not operate the pump with the base cover
removed.
CAUTION
Always allow cold equipment to warm to room tem-
perature before using it to prevent damaging the
system.
1. With the system fully primed, trigger the spray valve
briefly until an even flow of material is spraying out
of the tip.
STARTUP
5. You can see the material being drawn into the suc-
tion hose (if the hose is clean). As soon as you see
material flow through the priming tube, close the
priming valve. This usually takes less than 30 sec-
onds.
Failure to completely close the priming valve after
the system is primed will cause the valve to erode,
greatly shortening the valve life.
NOTE: If your system is hard to prime, first try to force
feed the suction 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. Heavy viscosity material
may need to be thinned. Be sure to follow the
material manufacturer 's recommendations on
thinning.
6. Trigger the spray valve to prime the outlet hose and
extension. Once primed, the motor will run 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 not triggered is normal.
OPERATION
2. Hold the spray tip approximately 12 in. (300 mm)
from the surface and start spraying.
3. For low pressure spraying, use the 431 size tip
supplied with the wand. This tip develops a spray pat-
tern at a very low pressure when spraying fluids
about the viscosity of water, such as wetting agents,
penetrating encapsulants and lockdowns.
4. For fine-finish spraying, use the fine-finish tip
which produces a fine mist for "glove bag" applica-
tions.
5. When you ARE DONE spraying, turn the ON/OFF
switch to OFF and trigger the spray valve.
6. Thoroughly flush the system immediately after each
use to keep it in good working order. See page 8.
