MAINTENANCE
WARNING!
Failure to observe the following before performing any maintenance could
cause serious injury or death from the sudden release of compressed air:
· Depressurize the blast machine.
· Disconnect power supply.
· Lockout and tag out 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.
To ensure a long and efficient operational life of the Deadman Handle, it is
highly recommended that the following procedures be followed:
1. Periodically(after 5-6 months of moderato use or after 10-15 hours of
heavy industrial use) replace all hose adaptors that are for abrasive flow
use only.
2. Periodically replace sealing block in deadman handle to maintain proper
shut-off.
3. Replace abrasive hose when it begins to soften or leaks media or air
around the hose or handle area.
4. Replace the nozzle when it wears to the next larger size.
5. Adjustment of sealing block may be required after nozzle change.
