MANUAL - SANDBLASTERS - U100-U103 Revised 2006-02
PREPARATION
IMPORTANT: OPERATOR SHOULD WEAR PROTECTIVE CLOTHING
Note: Item numbers given below refer to the parts listing on page 4.
1. On removal of sandblaster from carton, check for any transportation damage and make sure all parts
and accessories are included.
2. Make sure the Air Shut Off Valve (Item 8) is closed.
3. Make sure the Sand Flow Control Valve Item 11) is closed (handle in horizontal position).
4. Make sure the Nozzle End Shut Off Valve at the end of the Blast Hose is closed.
5 The choice of nozzle size is limited by the CFM air capacity of the compressor. For fast cutting or
cleaning, the nozzle should be no larger than necessary to permit the compressor to maintain 80
pounds of pressure when blowing continuously. Thus, 1/8” nozzles are supplied as standard parts for
the ½” sand hoses. This hose can be used for sand, steel grit and shot. See the previous page for
nozzle specifications.
6. All sand should be dry and uniformly graded to about #30 screen size for use with 1/8”, 3/32’ or 7/64”
nozzles. With larger nozzles, coarser grade grit, shot or beads may be used.
7. TO FILL THE SANDBLASTER – Make sure the Sand Flow Control Valve (Item 11) is closed, then:
a) Remove Filler Valve (Item 4) to make filling easier
b) Fill the tank from the top, making sure the abrasive is dry and running freely
c) Connect the air hose to the Air Shut Off Valve (Item 8)
d) Replace the Filler Valve and hold in place while you open the air valve and allow the tank to fully pres-
surize (about 20-30 seconds). The air pressure will then hold the Valve in place.
OPERATING INSTRUCTIONS
1. WHEN YOU ARE READY TO SAND BLAST: Open the Nozzle End Shut Off Valve at end of the Blast
Hose, then gradually open the Sand Flow Control Valve (Item 11). The valve first passes air only, then
increasing amounts of sand. When you have enough sand for the desired cutting effect, operate with the
Nozzle End Shut Off Valve if one is supplied. This valve is not for mixing and should be used either wide
open or closed. NOTE: You can tell when a good operating level has been reached by the cutting effect of
the abrasive when it hits the surface and by the “feeling” of the abrasive rebound force.
2. TO RELIEVE PRESSURE IN THE TANK: To refill or change nozzles etc, shut off the Air Shut Off Valve
(Item 8). Open the Pressure Relief Valve (10-251F) by inserting a finger into the ring and pulling down-
ward. IMPORTANT: It is recommended that the pressure be relieved whenever the unit is not being used
because air held in the tank under pressure can cause moisture condensation which can clog the sand
control valve. If the valve does get clogged, open the square-headed Drain Plug (Item 13) or the Filler
Valve and agitate the abrasive with a rod or wire.
3. TO EMPTY THE SANDBLASTER: Relieve the pressure as above, remove the Filler Valve (Item 4) and
open the Sand Control Valve (Item 11). Then remove the square-headed Drain Plug (Item 13) from the
bottom of the tank to drain the abrasive. NOTE: With the Filler Valve removed, abrasive may be vacu-
umed out through the top of the tank.

OPERATING INSTRUCTIONS (continued)
4. OPERATING TIPS:
a) Always operate with hose and control “wide open”. Adjustment for suitable abrasive flow should be
made independently using the Sand Flow Control Valve (Item 11).
b) Make sure you match the right combination of abrasive type and mesh size, nozzle size and air pres-
sure to the particular job at hand.
c) Nozzles should be changed whenever they wear sufficiently to lose their cutting power at lower than
80 PSI. Your efforts become inefficient after the nozzle orifice has worn to more than 11/2 times its
original diameter.
d) Use Tungsten Carbide nozzles for long, continuous operations.
e) If the unit has a Moisture Filter, check and drain it periodically by opening the valve at the bottom while
it is under pressure.
f) Repair the cause of any air leakage as soon as possible to avoid serious damage.
f) If an abrasive clog forms in the bottom of the tank, the Anti-clogging Valve (Item 17) may be used as
follows to remove the blockage:
• Open the Nozzle End Sut Off Valve and hold it open if necessary
• Make sure the Sand Flow Control is open
• Open the Air Shut Off Valve
• Open and close the Anti-clogging Valve repeatedly to send a series of air “pulses” down through the
tank. If the blockage remains, remove the Drain Plug (Item 13) and use a wire or rod to open the pas-
sage. For normal operation, leave the Anti-clogging Valve open.
5. REPLACEMENT OF HEAVY-WEAR PARTS: Keep a supply of quickly wearing consumable parts such
as ceramic nozzles, seal blocks, nozzle holder washers, plastic hood lenses etc on hand. Purchase
ahead of time if necessary.
6. NOZZLE SPECIFICATIONS: Sand and air consumption and the area cleaned depend on the type of
abrasive, air pressure, nozzle size and the condition of the surface to be cleaned.

a) The pressure vessels are manufactured to ASME standards.
b) All models come with a ½” ID Sand Hose.
c) Nozzle sizes range from 3/32” to 5/16”
d) Heavy steel grit or shot can be used with the ½” Sand Hose using 5/32” to ¼” nozzles.
e) For larger nozzles (3/16”, 5/16”) a ¾” ID Sand Hose is recommended.

MANUAL - SANDBLASTERS - U100-U103 Revised 2006-02
SEAL BLOCK ADJUSTMENT:
1. Proper adjustment is important to ensure efficent operation and prevent excessive wear of the Seal
Block.To accomodate size variations in the manufacturing of ceramic nozzles, elongated adjustment holes
are provided for seating the Seal Block. Fix the Seal Block in place by tightening the Seal Block Nut so
that the end surface of the Nozzle is in close contact with the Seal Block when the Control Lever is in the
closed position. There should be no gap between the two surfaces. Air leakage will be minimal but some
noise from escaping air is normal.
2. Each Seal Block can be used four times by changing the surface used. To change the surface, loosen
the lock nut and rotate the block to a new surface.
3. When a new nozzle is installed, the Seal Block must be readjusted to fit tightly against the new nozzle.
SAFETY SHUT OFF CONTROL - U5000F
1. OPERATION: To open the Control, squeeze the lever quickly. To close, release the lever quickly. To
avoid exposing the Seal Block to abrasive, do not open or close the Control slowly. Use the U5000F as
a working control only. When the job is finished, close the Sand Flow Control Valve (Item 11) and the Air
Shut Off Valve (Item 8), then release the air pressure by opening the Pressure Relief Valve by inserting a
finger into the ring and pulling downward.
2. REPLACEMENT:
a) Remove the Handle Tube from the Retainer Nut by turning the nut counter-clockwise.
b) Make sure the end of the hose is cut flat and square.
c) Apply grease to the outside of the hose for approximately 21/2” from the end.
d) Insert the hose into the Handle Tube making sure it is pushed firmly into the tube approximately 21/2”.
e) Secure the hose using the six screws provided.
f) Hold the Retainer Nut using a bench vise or vise grips and attach the Handle Tube by turning it clock-
wise with a pipe wrench. Make sure the Tube is firm and tight.The Seal Block is pre-adjusted at the fac-
tory to the Ceramic Nozzle supplied. If necessary, adjust the Seal Block as above to fit your nozzle and
minimize air leakage.
