1.34. DEPRESSURIZE VESSEL BEFORE PERFORMING MAINTENANCE.

Do Not remove, repair, or replace any item on this equipment while it is pressurized. Do Not
attempt to perform maintenance or load abrasive while this equipment is pressurized or is even
capable of being pressurized. This means the inlet ball valve should be closed and the air supply
should be shut off or disconnected. Anytime the manual blowdown valve is closed it should be
assumed that the abrasive blast vessel is pressurized.

An abrasive blaster is a Pressurized Vessel. The compressed air inside a pressurized vessel
contains a dangerously high level of energy which can propel objects and cause serious injury
or death. Depressurize vessel before performing any maintenance. See Section 6.2.

1.35. ALWAYS USE REMOTE CONTROLS.

Do  Not  sell,  rent,  or  operate  abrasive  blasters  without  remote  controls.  OSHA  regulations
require  remote  controls  on  all  abrasive  blasters.  All  abrasive  blasters  must  be  equipped  with
automatic (deadman) type remote controls (either pneumatic or electric). Failure to use remote
controls  can  cause serious  injury or death  to  the operator(s) or other personnel  in  the blasting
area. Reference OSHA 29 CFR 1910.244(b).

1.36. NEVER USE BLEEDER TYPE DEADMAN VALVES.

Do Not use bleeder type deadman valves on any Schmidt® abrasive blaster. The use of A-BEC,
Clemco, or a similar bleeder type deadman valve can, without warning, cause unintentional
start-up which can result in serious personal injury. A particle of dirt from the air hose can plug
the bleed hole in the deadman valve and cause the blast outlet to turn on.

1.37.

CHECK FOR DAMAGED PARTS.

Do Not use

this equipment with damaged components. Periodically check all valves, hoses,

fittings, pipe, and pipe fittings (internal and external) to confirm that they are in good condition.
Repair or replace any component that shows any sign of wear, leakage, or any other damage.
See Section 8.0.

Damaged components can fail during operation and result in serious injury or death to operating
personnel.

1.38.

ALWAYS USE SAFETY PINS ON HOSE COUPLING CONNECTIONS.

Do Not use

this equipment without hose coupling safety pins in place and hose whip checks

installed on all air and blast hoses. All blast hose couplings and air hose couplings have pin
holes that must be safety pinned to protect against accidental disconnections. Accidental hose
disconnection can cause serious injury or death. See Sections 5.14 and 8.7.

1.39.

ALWAYS USE CORRECT REPLACEMENT PARTS AND ACCESSORIES.

Do Not use replacement parts or accessories that are not rated for pressures equal to or higher

than the abrasive blaster’s operating pressure. Improper hoses and/or fittings used on, or
connected to the abrasive blaster can rupture and cause serious injury or death.

Do Not use replacement parts that are not Schmidt® original factory replacement parts. Non-
original parts may not fit properly and can cause equipment damage and/or failure which can
result in serious injury to operating personnel. Consult Axxiom Manufacturing, Inc. See Section
9.0 and Section 12.2.12.

Use of replacement components that are not Schmidt® original factory replacement parts may
result in equipment failure which can result in serious injury to operating personnel.
