AIR VALVE KNOB: The adjustable air valve knob lets you pre-set and maintain optimum cleaning force every time.

TRIGGER AIR VALVE: The squeeze-trigger air valve operates through a full range of pressures up to 250 psi. This lets you instantly match the cleaning force to the task.

THE HYDRO-AIR uses appro- ximately 3 cu. ft. of air per minute, varying of course with air pressure uses, and less than 3 gallons of water per minute with 70lb. water pressure.

AIR CONNECTION: Standard pipe thread. 3/8" air hose.

WATER CONNECTION: Standard hose thread. For best results use water pipe and " air line. Connect the Hydro-Air washer with 5/8" water hose and 3/8" air host, for best results.

S-31 SIPHONING ATTACHMENT: With the siphoning unit connected in place of the water line, detergents, degreasers, paint strippers, etc. are entrained in the air stream and will penetrate directly to the surface being treated without prior treatment. Rinsing is quickly accomplished by reconnecting the water line, and the job is finished in only two steps.

TO INSTALL: Connect air inlet to air hose with standard " pipe thread coupling or with a quick coupler, use " hose to assure the proper volume of air to the washer, connect water inlet to standard water hose of good quality with standard hose type coupler.

TO OPERATE: Air valve trigger controls air volume, open water adjustment (tube) with at least two complete turns of tube, for a fine mist close water adjustment to desired spray, the evffective force for removing heavy soil is at a distance of 3 feet or less from the surface to be cleaned.

TO SERVICE: Clean the air jet "A" of your Hydro-Air washer periodically, to do this remove both the number 1. large nut and number 2. nozzle tube, and clean out small air outlet through air jet with a piece of wire and reverse compressed air through the jet.
