3.7.7 If the nozzle was removed, thoroughly inspect

the nozzle holder threads for wear before installing the

nozzle washer and attaching the nozzle.

3.8 Shutdown

3.8.1 When finished blasting, and after cleanup is

completed, remove the respirator outside the respirator-

use area and where the air is safe to breathe.

3.8.2 Depressurize the blast machine.

3.8.3 Close the compressed-air supply valve at the

compressor.

3.8.4 Drain receiver tank, filters, and water collecting

devices, and bleed the compressed-air supply hose.

3.8.5 Shutdown the compressor.

3.8.6 Cover the machine when not in use. Refer to

Section 7.1 for optional covers.

4.0 PREVENTIVE MAINTENANCE

NOTE: These preventive maintenance instructions

pertain to the blast machine. Read the owners manuals

for all blast accessories, for their inspection and

maintenance schedules.

4.1 Daily Inspection

4.1.1 With the air off, before blasting, inspect the

following:

 Make sure that couplings are secure and lock pins

and safety cables are in place.

 For machines with manual controls, make sure the

nozzle supporting fixture is secure.

4.1.2 During blasting, inspect the following:

 Inspect all couplings and coupling gaskets for leaks.

 Check the blast machine for leaks. If leaks are found

around the pop-up valve, inspection door, or pipe

fittings at the bottom of the cone, stop blasting

immediately and repair or replace worn parts.

CAUTION

If leaks are allowed to continue, abrasive

erosion could cause extensive or irreparable

damage to the blast machine.

 Check all external piping, control hoses, and valves

for leaks. If leaks are found, stop blasting and repair.

 Inspect blast hose, couplings, and nozzle holders for

leaks. At the first sign of a leak, stop blasting and

inspect all items for wear. Replace worn parts.

WARNING

Leaks around couplings and nozzle holders

indicate worn or loose-fitting parts. Nozzle

holders and couplings that do not fit tightly on

hose, and nozzles that do not fit tightly in

nozzle holders could disconnect while under

pressure. Impact from nozzles, couplings,

hoses, or abrasive, and parts disconnected while

under pressure could cause severe injury.

4.2 Weekly Inspection

4.2.1 With the air off, before blasting, inspect the

following:

 Inspect the blast hose for wear; squeeze the hose

every three to four feet, look for soft spots. Soft

spots mean the hose is worn. Replace the blast

hose before the tube wears as far as the fabric plies.

WARNING

Worn blast hose could suddenly burst.

Couplings and nozzle holders may not

adequately grip worn hose, causing them to

blow off under pressure. Compressed air and

abrasive escaping from a burst hose, or

disconnected coupling or nozzle holder, could

cause severe injury.

 Remove the nozzle for inspection. Replace if the

diameter is worn 1/16 or more, or if the liner is

cracked.

 Make sure the nozzle washer is in place and not

worn.

WARNING

The threads on the nozzle and nozzle holder

must be inspected each time the nozzle is

secured to the holder. A loose fitting nozzle

may eject under pressure and could cause

severe injury. Check the threads for wear, and

make sure the nozzle holder securely holds the

nozzle. The nozzle washer must also be

inspected for wear. When nozzle washers are

worn, abrasive could erode nozzle threads.

 When an optional air filter is used, inspect the filter

element, and clean the bowl.
