Need help?Do you have a question about the Hotsy 797SS and is the answer not in the manual?
This document provides an operator's manual for Hotsy pressure washers, specifically models 797SS, 797SS-208, 897SS, and 897SS-208. It includes operating instructions, parts manuals, and important safety information.
The Hotsy pressure washers are designed for cleaning tasks, utilizing high-pressure water and, in some models, heated water. They are equipped with a pump to generate high-pressure water flow, a burner to heat the water (for hot water models), and various components for detergent application and control. The devices are intended for professional use, and proper operation and maintenance are crucial for safety and longevity.
The pressure washer features a pump that delivers a specific GPM to the high-pressure nozzle, which develops pressure. A relief valve provides secondary pressure release in the unlikely event of an unloader valve failure. The spray gun controls the application of water and detergent onto the cleaning surface, including a safety latch. A detergent injector allows for siphoning and mixing detergents. The wand must be connected to the spray gun. A high-pressure hose connects one end to the pump's high-pressure discharge nipple and the other to the spray gun. An unloader valve is a safety device that, when the spray gun closes, prevents over-pressurization.
The manual details the unpacking process, including the tools required for assembly (10" adjustable wrench and Teflon tape). It provides instructions for connecting the pressure hose, trigger gun, and wand, emphasizing the use of Teflon tape or thread sealant to prevent leakage.
Operation instructions cover getting started, including important safety, warning, and advertisement messages in English, French, and Spanish. It highlights the importance of proper installation in an enclosed area, adequate ventilation, and correct electrical connections. Specific instructions are given for burner startup, including turning on the burner switch, adjusting the air band, and observing the flame. Venting is crucial, especially for fuel-fired models, to ensure proper combustion and prevent the accumulation of carbon monoxide.
The manual outlines a comprehensive maintenance schedule to ensure the longevity and safe operation of the pressure washer.
Pump Lubrication: Lubricate the pump using 30W non-detergent oil. Check the oil level using the sight glass and drain/refill after the first 25 hours of operation, then every 3 months or 300 hours, whichever comes first.
Relief Valve: The relief valve is factory set and sealed. Tampering with it can cause injury or damage and voids the warranty. It should be inspected annually for any obstructions.
Unloader Valve: The unloader valve is factory set and sealed and is a non-adjustable part. Tampering with it can cause injury or damage and voids the warranty.
Burner Fuel Filter: Drain any accumulated water and clean or replace the element as needed.
A detailed troubleshooting guide is provided for common issues such as the pump motor not running, no water spray, low pressure, poor or no detergent flow, burner not igniting, and burner smokes or has an obnoxious odor. Each problem lists possible causes and corrective actions. For example, if the pump motor does not run, possible causes include a tripped GFCI, no voltage, or a tripped pump motor reset button. Corrective actions include resetting the GFCI, testing power supply, and pushing the reset button.
The manual also includes exploded views and parts lists for various assemblies, including the left side, right side, control panel, burner, fuel tank, float tank, pump, coil outlet, detergent valve, hose/spray gun/wand, and HM pump. Wiring diagrams for the 700 series are also provided.
