20 Gallon Pressure Abrasive Blaster
4. Squeeze the On/Off control valve of the deadman valve to relieve pressure in the tank (1).
NOTE:
The tank (1) is depressurized when the pressure gauge (15) reads 0.
5. Remove the tank filler cap (12) and empty the abrasive media into a suitable container to
collect the abrasive.
CAUTION! Take care when emptying the tank of abrasives not to damage the pressure gauge or water
separator filter.
NOTE:
To prevent abrasive from being blown out of the container, cover part of the container with a board or cloth
to limit the amount of dust scattered.
CAUTION! Wear protective head gear such as goggles and a face protector as well as breathing protection to
avoid breathing in the dust created when emptying the abrasive tank.
MAINTENANCE
NOTE:
Disconnect the air source and discharge any residual air pressure in the air line before performing
any maintenance.
1. The ceramic nozzle (37) will wear away over time, causing the internal diameter to widen and disperse the
media over a larger area, reducing the tool’s efficiency. The compressor will also need to work harder to
maintain the pressure. Check the ceramic nozzle at regular intervals and replace as appropriate.
2. Always check for cracks and leaks in the deadman valve, hose, and tank. These problems must be fixed
immediately due to the dangers involved with air under pressure.
3. Check for damaged parts. Before using any tool, any part that appears to be damaged should be carefully
checked to determine that it would operate properly and perform its intended functions. Check for
alignment and binding of moving parts, for broken parts or mounting fixtures, or for any other condition
that may affect proper operation.
NOTE:
Internal components of the unit will wear out after repeated exposure to the blasting process. When
the unit’s performance declines, have the unit serviced by a qualified technician.
4. Use only identical replacement parts or accessories intended for use with this tool when servicing. Replace
damaged parts immediately.
5. Keep the tool clean. Wipe the tool with a clean cloth and periodically blow out all areas with compressed
air. If compressed air is not available, use a brush to remove dust from areas. Do not use harsh chemicals
or solvents to clean the tool. These chemicals could seriously damage the housing.
6. The tank filler cap (12) is removable, make sure to clean and remove abrasives from the O-ring rubber
seal (11).
CAUTION! Make sure that the tank has been depressurized before attempting to remove the tank
filler cap (12).
7. After each use of the unit, perform the routine maintenance to your air compressor according to the
compressor manufacturer’s instruction manual.
8. If repairs are required, bring your tool to Princess Auto Ltd.
PLUGGED CONDITIONS
All blasting systems are prone to plugging or wear because of the abrasive material used. The blast nozzle may
become plugged from moist media. Try dislodging the media with a drill bit held in your hand. You will need to
discard the moist media.
The abrasive media contents of the tank (1) may be stirred to loosen the media as well.
