MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE
On the left side of your control box, a small brass petcock valve controls the vibrator speed. This vibrator valve must be
open during blasting. Adjust it so that you feel maximum vibration at the head of the machine. This will insure that all of
the media gets “shaken” to the bottom of the tank.
Over time, you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot. If the
system is not feeding right, adjust the valve by turning it towards the off position to slow the vibrator down, allowing the
pot to rattle more.
ABRASIVE NOT FLOWING CORRECTLY - Assuming proper Installation, air pressure, and abrasive.
Check media quality. Your machine is made to run with clean, high quality abrasive or media. Dirt will get muddy and clay
will harden.
NOTHING IS COMING OUT OF THE NOZZLE
The blast nozzle may become clogged with debris or blast media. If this occurs, put the machine in the blowdown
position, then remove the nozzle and inspect for a rock or other foreign material.
PINCH VALVE NOT OPENING OR CLOSING
1. Put the machine in the blowdown position.
2. Does the pressure gauge on the bottom left side of the control box read 80?
3. Are all ttings tightly secured to the deadman and the back of the box?
4. Is air bleeding out of the deadman?
IF YES
1. Unscrew the green hose from the control box.
2. Depress the deadman and verify air is coming out of the green hose.
If air is coming out of green hose:
1. Remove control box front panel and follow instructions for cleaning the control box valve.
2. Check that the O-Rings on the piston are not torn. If torn, order a repair kit. This part number is located on control box
back panel.
IF YES
1. Remove red hose from deadman to verify if air is coming out of it.
2. If no air is coming out, unscrew the red hose from control box and verify air coming out of it.
3. Remedy: Air line needs to be blown out to clean debris in line, and check to see if seat disk is worn.
