H.E.R.O. INDUSTRIES
1100C & 1100NC OWNERS MANUAL
Welcome to the world of H.E.R.O. airless paint spraying. We are sure you will enjoy owning and operating
your new H.E.R.O. model 1100NC. With H.E.R.O. airless spray equipment you will avoid the
inconvenience and mess of overspray. You are spraying paint, not air, and the paint is driven to the painting
surface in a clean, fan shaped spray which penetrates all cracks and corners. To attain these results, you must
adjust the pressure as low as possible. We recommend that you become familiar with your H.E.R.O. unit.
Discuss with your dealer the useful accessory items he has to offer - various types of tips, extension poles for
hard to reach areas, extra hose, etc. Use of accessory items is often the difference between a good job and an
excellent one!

INSTRUCTIONS
WARNING
Do not attempt to operate this machine until you have read and understood all safety precautions and
operating instructions. Equipment and chemicals when used improperly can be dangerous.
Your H.E.R.O. airless sprayer has been fully factory tested prior to shipment.
BEFORE STARTING YOUR H.E.R.O. PUMP....
CHECK to ensure that the shipping seal has been removed from under the cap on the hydraulic tank.
Hydraulic tank should be at least 3/4 full of H.E.R.O. LVO hydraulic fluid.
CHECK all fittings and connections in the pump system, hose, and gun to ensure that they are tight.
CHECK to ensure that there is a spray tip in the gun, and that the tip is the correct size for the coating you
are to spray. ( There are various tips available, for each type of coating or configuration. See " Airless Spray
Tip " on page 11 , for proper tip selection.
CHECK to ensure that you have H.E.R.O. strainer bags, H.E.R.O. Wonder Wash, appropriate thinner for
the paint, a waste container, and any other accessories you may require for the job.
CHECK to ensure that you have adequate extension cord size and length if the machine cannot be situated
immediately next to an electric outlet. Distances up to 50 feet require #12/3 wire grounded cord, up to 100
feet require #10/3 wire grounded cord. DO NOT exceed 100 feet of extension cord. If distance is greater,
obtain and install extra length of H.E.R.O. airless spray hose.
READ THIS MANUAL THOROUGHLY.
