5. If the diver operating the unit must be replaced or the cleaning operation must be interrupted

or terminated, shut down the engine by moving the throttle lever down to adjust engine RPM

to "MIN" (Figure 18) and turning the key to the "OFF" position (Figure 16). Turn off the feed

Ensure that the gun is submerged any time the engine and pressure pump are operating.

Adjusting the CaviBlaster

1. If using a calibration pressure gauge situated between the pressure hose and the CaviBlaster

gun, the water pressure should be 2,200-psi with the gun submerged and the gun trigger in

the open or "ON" position.

position. The flow of water through the bypass hose, in turn, determines the flow of water

through the pressure hose and the gun. Less flow through the bypass hose means more flow

through the gun which translates to higher velocity and pressure.

ensures that the bypass will open without a pressure shock wave damaging the pump when

the gun trigger is released to the closed position.

2. If using a pressure gauge located on the

CaviBlaster

power unit, the water pressure

will need to be higher to account for sidewall

friction loss in the pressure hose. The pressure

at the pump should be 2,800-psi plus 0.75-psi

per foot of pressure hose. For example, if using

the CaviBlaster

with 100 feet of pressure hose,

the pressure gauge located next to the pump

should indicate 2,875-psi. Pressure adjustments

are made in the same manner as described

above.

There should always be a trickle of

water through the bypass when the gun trigger

is in the open or "ON" position.
