! NOTICE
Air Flow Valve (B) adjusts how much air pushes
the abrasive through the Blast Hose (K). Less air
flow = more abrasive. More air flow = less
abrasive.
3.5.3
If necessary adjust Air Flow Valve (B) to
achieve the proper balance of abrasive and air. If
there is too much abrasive open valve more, if not
enough close the valve slightly. If the abrasive is
pulsating between thick and thin, you may need to
slightly close the Abrasive Flow Valve (D).

Sandcarving
3.6.1
Turn on cabinet power switch located above
the right cabinet access door; the dust collector and
lights should both begin operating.
3.6.2
Use (provided) rubber gloves before blasting.
(18mil or thicker rubber or latex safety gloves can
be purchased from a local hardware store.).
3.6.3
Place item to be etched inside cabinet. Hold
Blast Hose (K) in hand (like a pencil).
3.6.4
By pressing on the Foot Pedal (F), the
air/abrasive flow starts; by letting off the Foot
Pedal, the air/abrasive flow stops.
3.6.5
Depress Foot Pedal (F), holding Blast Hose
(K) 3

away from item, use slow sweeping
motions across image area to be etched.
! NOTICE
Always depressurize the pressure pot when you are
done blasting for the day. It is not necessary to do
this if you are intermittently blasting through out the
course of the day but should always be done when
you are done blasting for an extended period of
time. Instructions for depressurizing the pot are
covered below.
3.7
Depressurizing the Pressure Pot and
recycling the abrasive.
! NOTICE
Always use the following procedure when you are
finished blasting or you run out of abrasive.
! WARNING
NEVER attempt to open the pressure pot closure
cap using the Pressure Pot Closure Lever (L). This
could cause a sudden UNSAFE release of
compressed air. The pressure pot opens
automatically when the pot is depressurized.
3.7.1
After you are done blasting, or you run out of
abrasive during blasting, keep the dust collector
turned on and then turn off the Air Inlet Valve (C).
Then depress the foot pedal until the pot is
depressurized. When all the air pressure is
exhausted the pot closure cap will automatically
open and the abrasive that has collected in the
bottom of the cabinet will flow back into the pot.
You can get additional abrasive to fall back into the
pot by tapping on the outside of the cabinet just
above the pot. The pot is now filled again and is
ready for the next time you blast.
! NOTICE
If for some reason, the pot closure cap does not
open the pot after the Air Pressure Regulator Gauge
(H) has reached zero, you can open the closure
manually by pulling the Pressure Pot Closure Lever
(L) towards you. NOTE: for safety reasons this
should never be done unless the Air Pressure
Regulator Gauge (H) reads zero and the main air
supply is disconnected.
! WARNING
Never leave the pot pressurized over night. If valve
( C ) is left on and the air compressor supply shuts
off at night the pot will depressurize and
automatically open. When the air compressor
comes back on the next day, air will run through the
opened pot and abrasive and dust will blow out
through the arm holes of the cabinet creating a
hazardous condition of dust in the air.
