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 1100MD is manufactured to perform at;
2650 psi
2250 psi
If your unit is unable to perform to the above pressure levels consult the troubleshooting guide for the required repair procedure.
