Maintaining your Blast Pot
CONTROL BOX MAINTENANCE
The control box has its own pressure regulator. This is already set properly from the factory, and should not be tampered
with. If it gets changed, make sure to readjust it to 90 PSI.
CONTROL BOX VALVE (LOCATED NEAR IN CONTROL BOX)
It is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly.
To service the control box valve (located in the control box), follow these steps:
1. Depressurize the machine.
2. Label each endcap left or right.
3. Remove the 2 (two) screws and set endcaps aside.
4. Remove piston.
5. Lightly lubricate piston with supplied grease or install new piston.
6. Install or replace any damaged gaskets or O-rings.
7. Re-install both endcaps.
PRESSURE REGULATOR
You should occasionally lubricate the threads on this knob with a lubricant such as lithium grease.
FILTER REGULATOR
You will find the filter regulator on the left side of control box. The filtered moisture and debris will collect at the bottom
where it is vented through the screw. Leave the screw cracked open so it can let the moisture out continuously.
CONSUMPTION CHART
No damage to the machine will occur by leaving water and media inside of it. However, due to the organics in the media, a
foul smell can occur when left stagnant for longer than 24 hours. For this reason, when the machine will not be in use for
an extended period of time, it is recommended that you remove water and media from machine either by blasting it out or
by removing the bottom flange, air inlet jet, and gasket, and allow it to drain.
Blast pots do not need to be completely filled to operate. If maximum blast time is not needed, fill blast pot according to
required blast time.
