3. If the diver operating the CaviBlaster® unit must be replaced or the cleaning operation must be
terminated, disengage the pressure pump by moving the Start Switch to the OFF position 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 pressure (up to 2,000-psi) water stream, which can cause
injury when the gun is out of the water. ALWAYS keep the gun submerged when the
pressure pump is engaged.
Operating the CaviBlaster® system:
1. When the diver is ready to commence cleaning operations, ensure that the gun is submerged in
water. Then move the Start Switch to the ON position.
2. 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.
3. Activate the cleaning cavitation stream by squeezing the trigger to the open or “ON” position.
4. 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° angle to the surface being cleaned. 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. (Figure-10).
5. Wear neoprene or rubber gloves to protect the hands and follow all safety regulations that may
be applicable to the work being performed.
6. 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 Switch to the OFF position (Figure-7) Turn
off the water feed and then release the water pressure in the hose(s) by squeezing the gun
trigger to the open or “ON” position
while under water
. Revert back to step 1 of the operating
instructions when the replacement diver is ready to continue cleaning.
7. Ensure that the gun is submerged any time the engine and pressure pump are operating.
