MAINTENANCE
WARNING!
Failure to observe the following before performing any maintenance could cause serious
injury or death from the sudden release of compressed air:
 Disconnect power supply.
 Lockout and tagout the compressed air supply.
 Bleed the air supply line to the blast gun.
Immediate replacement of worn components is required. Failure to replace worn components
could expose the operator or bystanders to high speed media and compressed air could
cause death or serious injury.
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.
