Start Up and Adjust Pump
Air-Powered Pumps
1.
Supply fluid to the pump, per the requirements of
your system.
2.
Be sure the pump air regulator (H) is closed.
3.
Open the bleed-type master air valve (J).
4.
Hold a metal part of the valve firmly to the side of a
grounded metal pail and hold the trigger open.
5.
Adjust the pump air regulator (H) until the pump
starts.
6.
Cycle the pump slowly until all air is pushed out and
the pump and hoses are fully primed.
7.
Release the valve trigger and lock the trigger safety.
The pump should stall against pressure.
8.
Use the pump air regulator to control the pump
speed and the fluid pressure. Always use the lowest
pressure necessary to get the desired results.
Higher pressures cause premature nozzle and
pump wear.

Hydraulic-Powered Pumps
1.
Supply fluid to the pump, per the requirements of
your system.
2.
Open the dispensing valve(s).
3.
To adjust the system, perform the following proce-
dure:
a.
Turn on the hydraulic power supply.
b.
Open the flow control valve (H) all the way.
c.
Adjust the pressure-reducing valve (K) until you
get the desired fluid pressure. Run the pump
until all air is purged from the fluid lines.
d.
Count the cycle rate of the pump.
e.
Close the flow control valve (H) until the cycle
rate and fluid pressure start to drop.
f.
Open the flow control valve slightly until the
cycle rate and fluid pressure return to the
desired level. This method of setting the hydrau-
lic controls ensures proper pump operation and
will prevent pump runaway and damage if the
fluid supply runs out.
4.
Release the valve trigger and lock the trigger safety.
The pump should stall against pressure.
5.
Always use the lowest pressure necessary to get
the desired results. Higher pressures cause prema-
ture nozzle and pump wear.

Keep hands and fingers away from the priming piston
during operation and whenever the pump is charged
with air. The priming piston extends beyond the intake
housing to pull material into the pump and can ampu-
tate a hand or finger caught between it and the intake
housing. Follow the
on
page 13 before checking, clearing, or cleaning the
priming piston.
