Operation
Dispensing
1. Start the fluid supply pump.
2. The fluid flow rate is controlled at the pump. Adjust
the pump pressure to obtain the desired flow rate.
It is recommended that you use the lowest pres-
sure necessary to dispense the fluid. The pressure
adjustment will depend on the hose length, the
viscosity of the fluid, and the gun nozzle size.
3. Unlock the gun trigger safety.
4. Squeeze the trigger in all the way. Fluid flow
begins with the slightest pressure on the trigger
and stops when the trigger is released.
NOTE: Periodically inspect the vent in the gun handle
for fluid buildup which could indicate an internal leak.
See Fig. 3. Service the fluid tube and o-ring as
needed.
