Important Safety Note (Non-ASME Requirement)
Flammable Materials Warning: If this pressure tank is used for spraying flammable materials, the operator must not pressurize the tank more than 15 PSI to meet OSHA requirements for non-ASME pressure vessels.
- Max tank pressure: 80 PSI. Do not adjust the safety relief valve. If it vents air, reduce the air inlet regulator setting.
- Do not alter the tank by welding, drilling, or machining.
- Always ground the tank with a 12 ga. wire to a known earth ground to prevent static sparks.
- Relieve tank pressure completely before removing the cover or material fill cap. Shut off air supply and vent pressure using the vent valve on the lid.
