What to do if my Simoniz 039-8583-4 Pressure Washer has no pressure or low pressure?

If your Simoniz Pressure Washer has no or low pressure, consider the following: * Ensure the required tip nozzle is attached. * Make sure the water supply faucet is turned on fully. * Check that the water supply pressure is adequate and there are no kinks or blockages in the hose; ensure the faucet is fully on and that the water from the supply line is a minimum of 30psi, 4GPM. * Clean the water filter. * Replace any worn o-rings at the connection point. * Squeeze the trigger to release air in the pump while the machine is running. * Set RPM (Throttle lever) to MAX (not applicable to SKU#199- 1010-8 2600psi pressure washer).
