UNLESS YOU ARE KNOWLEDGEABLE ABOUT THE REPAIR OF HIGH PRESSURE EQUIPMENT, DO NOT ATTEMPT TO REPAIR AN AIRLESS SPRAYER YOURSELF. ALWAYS FOLLOW ALL SAFETY PRECAUTIONS. THE H.E.R.O. SERVICE VIDEO TAPE (1-620-VHS OR 1-

620-BETA) WILL PROVIDE COMPLETE SERVICE TRAINING. SEE YOUR H.E.R.O. DISTRIBUTOR TO PURCHASE A COPY.

PRESSURE TEST

To verify the operation of an airless sprayer, use of pressure gauge is required. A pressure gauge (min. 3000 psi) installed at the gun, using a new .021 tip, and not less than 50 feet of H.E.R.O. airless spray hose is needed. If you do not have access to these items, your local H.E.R.O. authorized service center will be able to perform this test. Your model 1100NC is manufactured to perform at;

2650 psi -- Static pressure, with lock ring (ref# 73) on pressure control valve (ref# 70). 1950 psi -- Pressure drop, when gun trigger is squeezed.

2250 psi -- Spraying pressure, after recovery time.

If your unit is unable to perform to the above pressure levels consult the troubleshooting guide for the required repair procedure.
