2.11 Adding Abrasive Media
The system has been shipped without the abrasive
media in the pot. Turn the dust collector on, place
unopened 50lb bag of 150 grit aluminum oxide
abrasive into the cabinet. Slit the center of the bag
open. Close the side door and empty the bag using
the front armhole access. After the dust has cleared
remove the bag from the cabinet.
! NOTICE
The abrasive media will break down over time
causing more dust in the cabinet and slower
blasting. New abrasive should never be added to old
abrasive. Instructions for removing worn abrasive
and adding new abrasive are covered in the
Operation Manual. DO NOT over fill the pot with
more than 50 lbs of abrasive; this may prevent the
pot closure cap from sealing.
2.12 Air Compressor Requirements
NOTE: Customer Supplied and used only
for the Cabinet.
The following or similar items are recommended
for moderate cabinet use. www.grainger.com or
call 800 225 5994

Tank Capacity (Gal): 20
2. Water Trap
3. Air hose
2.13 Dedicated Air Compressor Set-up
! NOTICE
DO NOT connect air to the cabinet until you are
instructed to do so in the operation manual. Follow
all procedures found in compressor manufacturers
literature.
2.13.1 It is highly recommended that you install a
water trap to the compressor. Moisture getting into
the abrasive can cause the pressure pot to clog and
prevent the flow of abrasive. If you are using a
water trap, install it to the output connection on the
compressor. This connection is generally after the
air pressure regulator.
2.13.2 Connect air hose to water trap.
2.13.3 The end of the air hose should have a quick
disconnect coupling that will connect to the fitting
(N) on the pressure pot.
2.13.4 Turn on the compressor and let it fully charge
with air but DO NOT connect the air hose to the
cabinet yet.
2.13.5 Air compressors generally have an output
regulator and two air pressure gauges. One gauge is
to indicate the pressure in the tank and the other is
the output pressure the customer sets. Set the
output pressure regulator to 90 psi.

Locate the Operation Manual to continue.

SAFETY INFORMATION
DO NOT attempt to operate this equipment until you have read and understand the
potential hazards associated with operating this equipment and are able to follow all
safety and operating procedures found in the safety manual and this operation manual.
Potential hazardous situations are identified whenever you see the following alert:
! WARNING
3.0 OPERATING INSTRUCTIONS
! NOTICE
10/4/2010 (9:19 AM)
2034 - 3 - Operation v4.05
When a ball valve handle is parallel to the valve or
pluming, the valve is wide open. When a ball valve
handle is perpendicular to the valve, it is completely
closed.
OPEN CLOSED
3.1 Pressure Pot Settings: The Pressure Pot
has two adjustment ball valves that can regulate the
abrasive/air flow mixture. The standard settings for
the pressure pot should be made as follows:
3.1.1 Set Abrasive Flow Valve (D) at approximate
half way open or approximately 45° angle.
Abrasive
45º Air Flow 45º
Set Air Flow Valve (B) approximately half way
open or at 45° angle. Adjustments will need to be
made as wear occurs to Blast Hose (K) and Blast
Nozzle (T).
! NOTICE
Abrasive Flow Valve (D) usually does not require
adjustments from the 45 degree position unless
there are drastic pressure changes, or larger nozzle
orifices are used.
3.2 Connecting Air to Cabinet
3.2.1 Before connecting the air hose from the
compressor to the pot, make sure the Air Inlet Valve
(C) is in the “OFF” position (horizontal) and the air
compressor has been set up according to
instructions found in the Rayzist setup guide.
3.2.2 Connect the compressor air hose to the Air
Inlet Valve Quick Disconnect Plug (N) but DO
NOT turn the air inlet valve (C) to the on position
yet.

10/4/2010 (9:19 AM)
2034 - 3 - Operation v4.05
! NOTICE
The pressure pot is equipped with a safety relief
valve (U). If the pressure from the air regulator (A)
rises above 100 psi the relief valve (U) will pop
open and release air. Since your incoming air is to
be adjusted to 80-90 psi this should never happen.
This is a safety device and should never be used to
drain air from the pressure pot. Draining air from
the pot using this valve will cause abrasive to enter
and damage the regulator.
! NOTICE
The air pressure regulator (A) sets the blasting
pressure, which can be seen in gauge (H) only after
the pressure pot has been pressurized. It is factory
set at 30 psi.
3.3 Pressurizing the Pressure Pot
The pressure pot opening is located inside the
cabinet below the metal grate. The pressure pot
closure cap is attached to a linkage, which is
movable from the pressure pot closure lever (L) on
the left side of the cabinet. The purpose of the lever
and linkage is to lift the pressure pot closure cap
upward to contact the pressure pot rubber seal
located at the top of the pot. While holding the cap
in the up position with lever (L) the air is turned on,
this fills the pot, and presses the cap securely
against the pressure pot rubber seal, sealing the pot
and pressure inside. When the cap is in the down
position there is a gap between the cap and the seal,
which allows the abrasive from blasting to re-enter
the pot.
! WARNING
Ensure that the Blast Hose (K) is in the cabinet at
all times when the pressure pot is under pressure.
3.3.1 Locate the Pressure Pot Closure Lever (L) and
move it back and forth rapidly several times to
shake off any abrasive that may be sitting on top of
the closure cap.
3.3.2 Now push the lever away from you to lift the
pressure pot closure cap against the rubber seal.
While holding the lever firmly in this forward
position, open the Air Inlet Valve (C). Count 3
seconds and then release the Pressure Pot Closure
Lever (L). The pot should be closed and
pressurizing at this point. The Air Pressure
Regulator Gauge (H) should rise to the factory pre-
set blasting pressure of 30 psi.
3.3.3 NOTE: If you hear air escaping inside the
cabinet, turn off lever (C) and try again. If for some
reason you cannot get the pressure pot closure cap
to seal, call Rayzist and ask for technical help.
3.4 Adjusting Blasting Pressure.
3.4.1 After pressurizing the pot the pressure
regulator gauge (H) should read about 30 psi. If the
gauge has a different reading make an adjustment as
follows: Unlock the Air Pressure Regulator Knob
(A) by pulling upwards. Twist clockwise to
increase blast pressure or counter clockwise to
decrease blast pressure. Set regulator to desired
pressure, and then press down to lock the knob.
3.5 Adjusting Abrasive and Air flow
3.5.1 Turn on the dust collector and lights and check
the plastic dust bag on the dust collector to make
sure it is collapsing; this indicates it is properly
installed and has sealed the dust collector opening.
! NOTICE
When first stepping on the Foot Pedal (F), you may
experience a thick burst of abrasive media from the
blasting tip, which should smooth out to a constant
flow of abrasive and air. This occurs when Abrasive
Flow Valve (D) is open too far. When starting to
blast you should hold the blasting tip away from the
item you are blasting until abrasive media is
flowing smoothly.
3.5.2 Put on the rubber blasting gloves and hold the
Blast Hose (K) and have the tip pointing
downwards towards the grate about 6" to 8" away.
Step on the foot pedal and watch the flow of
abrasive as described above.

10/4/2010 (9:19 AM)
2034 - 3 - Operation v4.05
! 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).
3.6 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"- 4"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.
