This cylinder ships empty and must be filled by a qualified propane filling station before use. The built-in gauge is helpful for approximate fuel level, but proper filling should still be performed by trained personnel using approved propane filling procedures.
Before use, have the empty cylinder filled by a qualified propane supplier. Keep the cylinder upright and secure during transport, storage, and operation. Connect only to compatible propane regulators, hoses, adapters, or appliances, then leak-test all connections with approved leak detection solution before use.

Propane is flammable. Always transport and store cylinders upright and secured, use only compatible propane fittings and regulators, and leak-test connections before use. Never store propane cylinders inside living spaces or near ignition sources. If propane odor is detected, shut off propane if safe, ventilate the area, avoid flames/sparks/electrical switches, and have the system inspected before use.
