7. Do not use this equipment in any area that might be considered hazardous or where
flammable gases or liquids are present. Failure to do so may cause an explosion
resulting in serious injury.
AIR COMPRESSOR RECOMMENDATION:
To permit efficient operation of your air compressor, follow these guidelines:
1. Use a smaller size nozzle and air jet to control the demand of air.
2. Do not blast continuously. Stop blasting operation periodically to allow the compressor to cool.
No compressor is designed to constantly run at full RPM. Use 70% of the rated output.
3. Use a minimum 1/2” air hose or metal piping from your air compressor to the blaster. If your
compressor is creating an excessive amount of moisture, we recommend using a water trap or
a moisture separator.
4. The air compressor should be drained at the bottom of the supply tank through a drain valve
and should be blown down daily. It is not unusual to drain three or four gallons of water from
the supply tank on a high humidity day. An additional supply tank will help.
5. Keep dust and media created by blasting away from the air compressor unit. Observe
maximum air pressure requirements for the blaster and either set your compressor to run
within these limits or use a pressure regulator valve to reduce the air pressure to the
appropriate range.
ABRASIVE (MEDIA) USAGE:
1. If moisture is in the media it will eventually damage the blaster tank or plug the system. Keep
the media and compressor air dry to avoid this problem.
2. If media is moist, screen it and dry it before using.
3. Do not leave media in the tank after blasting because it can absorb moisture and impair
blasting performance.
4. Store media in a dry place; keep media off the ground or concrete floors. Put it on a wooden
skid.
5. If the humidity is excessively high, it may not be advisable to blast at that time.
6. Consider using different grades or different types of media to prevent nozzle clogging due to
high moisture content.
7. Do not use sand.
