2.
If using a pressure gauge located on the CaviBlaster
TM
power unit, the water is adjusted as
described in step 1 above. However, pressure will need to be higher to account for sidewall
friction loss in the pressure hose. The pressure at the pump should be 2,200-psi plus 0.75-psi
per foot of thermoplastic pressure hose. For example, if using the CaviBlaster
TM
with 100
feet of pressure hose, the pressure gauge located next to the pump should indicate 2,275-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 Zero Thrust Gun trigger is in the open or
“ON” position.
3.
If adjusting the CaviBlaster
TM
without a pressure gauge, close the pressure-regulating
unloader until there is just a trickle of water (less than ¼ gallon or 1 liter per minute)
coming out of the bypass with the Zero Thrust Gun trigger in the open or “ON” position.
Shutting down the CaviBlaster
TM
power unit:
1. Stop the motor by depressing the red “STOP” button (Figure 8) on the motor controller.
2. Shut off the supply of water to the pump.
3.
Squeeze the Zero Thrust Gun trigger to the open or “ON” position (Figure 9) to release the
water pressure remaining in the hose(s)
while the Zero Thrust Gun is submerged
.
4. It is now safe to remove the Zero Thrust Gun from the water.
5. Flush the system and rinse the power unit with fresh water at the end of the day.
Maintenance of the CaviBlaster
TM
unit:
1. Empty and clean the inline strainer every day.
2. Check the pressure pump oil level and consistency every day.
3. Flush the system and rinse the power unit with fresh water after each days use.
4. Inspect the pump drive belt every week and replace the belt when cracking appears.
5. Change the oil in the pressure pump after the first 50 hours and every 500 hours thereafter.
6. Change the spring for the Zero Thrust Gun trigger every 12 months or less if required.
