6. Connecting the sand outlet valve to the deadman valve
(See figure 6).
a. Slide the two hose clamps (23) over each end of the abrasive
hose (24). Press one end of the hose (24) over the hose
barb (49) on the abrasive outlet manifold (22) and the other
end of the hose (24) over the hose barb (49) of the
deadman valve.
NOTE:
Both hose ends should be firmly seated on the hose
barbs.
b. Slide the hose clamps (23) along the hose to each hose barb
at each end of the hose (24) and tighten hose clamps (23) firmly.
NOTE:
They have to resist the force
of 65 to 125 PSI.
7. Fasten the two handlebars (6) to the tank using four
pan screws (8) and four washers (50) and four
hex nuts (9) (See figure 7).
NOTE:
Position the curved ends of the handle bars
(6) at the top of the tank (1).
8. Assembling the axle and wheels (See figure 7).
a. Slide the wheel axle (5) through the holes in the
bottom of the handle bars (5).
b. Place one wheel washer (51), wheel (2), and
then another wheel washer (51) at each end of
the wheel axle (5) and secure with the cotter pins (3).
9. Insert the front foot (4) into the fitting on the
bottom of the tank (1) near the edge. Use the cotter
pin (3) to secure the front foot (4) to the tank (1)
(See figure 7).
10. Before beginning operations, check each connection, double checking to ensure that all of the connections
are tight and properly seated.
OPERATION
LOADING ABRASIVES INTO THE TANK
1. Check your abrasive to be sure that it is dry and won’t clog the steel abrasive shut-off valve (18B), abrasive
outlet manifold (22), abrasive hose (24), or other components.
2. Put on protective clothing and equipment.
3. Turn the brass air supply valve (18) to the OFF (horizontal) position.
4. Turn the brass shut-off valve (18B) to the ON (vertical) position.
5. Watch the pressure gauge (15) and make sure that it reads zero pressure.
6. Remove the filler cap (12) from the top of the tank (1).
7. Insert the funnel (29) and pour the abrasive media into the funnel. Fill the tank to no more than 3/4 full, or
the amount required to complete the task at hand if less sand is required.
NOTE:
If the humidity is 90 to 100%, the water separator filter won’t be able to trap all of the moisture in a
3/4 full tank. It is better to reduce the amount of abrasive and load the tank more frequently making sure to
empty the water separator filter when needed. This will reduce the possibility of clogging the bottom of the
tank or the line.
