HydraMaster Corporation

PORTABLE PROPANE TANK:

Do not use a portable tank inside of the truck or van.

It is dangerous and illegal in most states.

TRANSPORTATION OF FUEL CONTAINERS:

Transportation in a vehicle of any

vented fuel container that presently has or has ever contained a flammable liquid is

strictly forbidden by HydraMaster Corporation and by federal and state regulation.

The use of some chemicals through your mobile carpet cleaning plant can seriously

damage the internal plumbing, high-pressure pump, chemical pump and heat ex-

changers. These harmful chemicals include concentrated acid (see the pH chart at

the end of this section), solvents (including d-Limonene), and some paint, oil and

grease removers with a high concentration of solvents.

WARNING

CAUTION
