Using the Feed Hose.
The feed hose has the feed pump on one end and a cam-lock socket on the other end (Figure 7 . Insert the
electrical plug powering the feed pump into the waterproof electrical outlet on the end of the power unit
cart on the handle (Figure 9 .
Ensure that the knob on the plug is facing up and mates with the notch in the outlet cover. If the plug is
engaged upside down, the pump will turn in reverse.
Ensure that the feed hose is connected to the pressure pump, the feed pump is submerged in water, and the
wiring splice is kept dry prior to starting the feed pump.
Either fresh water or seawater can be used with this system.
Note: The feed pump has had a neoprene check valve installed in the discharge. This valve will
prevent water from draining out of the feed hose through the feed pump when the pump is turned
off. However, this check valve somewhat restricts the flow of water from the pump. If maximum
water flow is required from the feed pump, the check valve and stainless retaining washer can be
removed from the pump discharge by removing the black hose barb fitting.
When feeding the CaviBlaster with an alternate water source.
The source must supply water at a volume of greater than 13 gallons per minute at a maximum
pressure of 70-psi. Connect the water source to the inlet of the pressure pump (Figure 10 . Ensure
that the feed hose is connected to the pressure pump and the water is on prior to starting the
pressure pump.

Starting the CaviBlaster ower unit:
1. Connecting hoses and fuel tank to the CaviBlaster
By-Pass Hose (Figure # 9
Feed Hose / Pump (Figure # 8 , drop in water source make sure is one feet underwater.
High Pressure Hose (Figures # 11, 17 , without the gun, to clean the hose before starting to work
Fuel Tank (Figure # 10 Open tank cap to allow air flow.
2. When using the feed pump, start the feed pump by pulling the feed pump switch located on the cart
handle (Figure # 12 up to the “ON” position. When using a supplied water source, open the valve
to supply water to the system.
3. Ensure that the system is primed with water and that there are no leaks in the system. The pressure
pump is a positive displacement pump and water must be supplied under pressure. Failure to
um feed water to the ressure um will result in damage to the um . Make sure the feed
hose has no air bubbles.
4. Turn key to start the engine (Figure # 13 , Let unit warm up running for a few minutes, this will
circulate water in the system cleaning hoses and pump.
5. Once the unit is warm, power off the unit, turning off the Key counter clock wise (Figure #
13 , turn Off the feed pump (Figure # 12 .
6. Connect the Zero Thrust Gun (Figure # 15 to the High Pressure Hose (Figure # 11 and
submerge the gun into the water.
7. Restart the feed pump (Figure # 12 .
8. It is recommended that the gun trigger be in the open or “ON” position when starting the engine.
This will prevent a pressure shock wave from damaging the pump in the instant that the engine is
started.
9. Apply appropriate hearing protection prior to starting the engine.
10. Re-Start the unit (Figure # 13 Once the Diver is under water
11. When the diver is in position to work move the Throttle to MAX for full power. (Figure # 16

Recommendations for Effective Results.
Once the engine is throttled up to operating speed and the water trigger is pulled, the diver has to find the
most effective distance between the gun nozzle and the surface being cleaned.
When the diver is ready to commence cleaning operations, ensure that the gun trigger is in the open or “ON”
position (Figure # 15 , the gun is submerged in the water and the feed pump is operating prior to throttling up
the engine. Ensure that the power unit operator and other people working in the vicinity of the power unit
wear appropriate hearing protection when the engine is running.
1. Engage the pressure pump by pushing the throttle knob (Figure # 16 to the operating speed
position (fully extended to engage the centrifugal clutch.
2. The most efficient operating technique is to hold the nozzle 2-5 inches (5-12 cm away from the
surface to be cleaned and at a 25 to 45 degree angle to the surface being cleaned (Figure # 18 .
The diver needs to observe the shape of the cavitating jet cone. At greater depths, the higher
ambient pressure will cause the jet cone to be shorter. The widest zone of the cone is the most
efficient part of the cavitating jet. Placing the nozzle closer than 2 inches (5 cm from the surface
being cleaned will not allow for efficient cavitation performance and will degrade the cleaning
capability of the CaviBlaster system.
3. Follow all safety regulations that may be applicable to the work being performed.
4. If the diver operating the CaviBlaster unit must be replaced or the cleaning operation must be
terminated, disengage the pressure pump by pulling down the throttle lever into the idle position
(Figure # 16 and release the water pressure remaining in the hose(s by moving the gun trigger
to the open or “ON” position while under water. Revert to step 1 of the operating instructions
when the diver or replacement is ready to continue cleaning.

WARNING: Although the CaviBlaster® system is safe to use when
submerged in water, the system generates a high-
ressure (u to 2,500- si) water stream, which can cause
injury when the gun is out of the water. ALWAYS kee
the gun submerged when the ressure um is engaged.
O erating the CaviBlaster® system:
1. When the diver is ready to commence cleaning operations, ensure that the gun is submerged
in water. Then move the throttle lever up to adjust the engine RPM to “MAX” (Figure # 16 .
Ensure that the power unit operator and other persons working in the vicinity of the power
unit wear appropriate hearing protection when the engine is running. If the diver is not
wearing a helmet, hearing protection is recommended. CaviDyne recommends “Doc’s
Proplugs” vented earplugs or equivalent for diver hearing protection.
2. Activate the cleaning cavitation stream by squeezing the trigger to the open or “ON” position
(Figure # 15 .
3. The most efficient operating technique is to hold the gun 2-3 inches away from the surface to
be cleaned and at a 25 to 45 degree angle to the surface being cleaned (Figure # 18 . Placing
the gun closer than 2-3 inches from the surface being cleaned will not allow for efficient
cavitation performance and will degrade the cleaning capability of the system.
4. Wear neoprene or rubber gloves to protect the hands and follow all safety regulations that
may be applicable to the work being performed.
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 # 16 and turning the key to the “OFF” position (Figure # 13 . Turn off the
feed pump (Figure # 12 , and then release the water pressure in the hose(s by squeezing the
gun trigger to the open or “ON” position (Figure # 15 while under water. Revert back to
step 1 of the operating instructions when the replacement diver is ready to continue cleaning.
6. Ensure that the gun is submerged any time the engine and pressure pump are operating.

Adjusting the CaviBlaster system for maximum erformance:
1. If using a calibration pressure gauge situated between the pressure hose and the CaviBlaster®
gun, the water pressure should be 2,500 psi with the gun submerged and the gun trigger in the
open or “ON” position. The pressure is adjusted by turning the nuts on the end of the
pressure-regulating unloader (Figure # 19 .
This adjustment increases or decreases the flow of water through the bypass hose when the
CaviBlaster gun trigger is in the open or “on” 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. There should always be a trickle of water through the bypass
when the gun trigger is in the open or “ON” position. This 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 2,500-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 2,575 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.
3. If adjusting the CaviBlaster without a pressure gauge, close the pressure-regulating unloader
until there is just a trickle of water (less than ¼ gallon per minute coming out of the bypass
with the gun trigger in the open or “ON” position.

While the CaviBlaster system is very safe, operators should exercise care when using the
equipment. The cavitation “flame” can be safely passed over the operators’ skin at normal
operating distances of 2” – 3” from the tip of the nozzle. However, at very close distances
(typically less than 1” both nozzles are capable of causing harm to the operator, particularly
in the initial instant that the system is activated. For that reason, o erators should exercise
caution when o erating the gun with the nozzles in close roximity to the body. The
o erators should also ensure that the reverse-thrust nozzle guard is secured in the
correct osition rior to o erating the gun.
The operators of the CaviBlaster system should always wear neoprene or heavy rubber
gloves to provide protection to the hands and, in particular, to the nails. The gloves will
absorb most of the energy produced by bursting cavitation bubbles and prevent the cavitation
bubbles from contacting the operators’ hands. The gloves will also protect operators’ hands
from the initial shockwave when the gun is activated.
Serious harm and injury may result from the misuse of CaviBlaster system equi ment
or im ro erly selected fittings, hoses or attachments. All components of the system
should be checked against the manufacturers’ instructions to ensure that they are compatible
with the pressures being used and of the correct thread type and pressure rating for the
intended service. Refer to these Operating Instructions and to the engine and pressure pump
manufacturers’ operation manuals for instructions or call CaviDyne, LLC at (352 275-5319
with any questions.
