Frequently Asked Questions - 855 Hotsy
How do I start the Hotsy 855 pressure washer?
Ensure fuel and oil are at proper levels. Turn the fuel valve ON, set the choke to CLOSED, move throttle to FAST, and pull the recoil starter. Once warm, open choke. Always follow safety guidelines from the manual.
What type of oil should I use for the pump and engine?
For the engine, use SAE 10W-30 (Honda recommended). For the triplex pump, use non-detergent SAE 30 or 10W-30 oil. Change pump oil after first 50 hours, then every 500 hours.
How do I clean clogged nozzles?
Turn off the unit and disconnect the spray gun. Use the supplied nozzle cleaning tool or a thin wire to remove debris from the nozzle orifice. Never use a metal object that may damage the nozzle.
Why is the pressure low or fluctuating?
Common causes: air in the system (purge by squeezing trigger without nozzle), clogged inlet filter, worn nozzle, or inlet water flow less than 4 GPM. Check water supply and nozzle condition.
How should I store the pressure washer during winter?
Drain all water from the pump and hoses. Run RV antifreeze through the pump to prevent freezing. Store in a dry, above-freezing location. Also stabilize fuel or drain the carburetor.
What safety precautions should I take when using the Hotsy 855?
Always wear eye and ear protection. Never point the spray at people or pets. Use a GFCI outlet for electric models (this is gas). Keep children away. Read the entire manual before operation.
Can I use bleach or other chemicals?
Yes, the built-in soap injector allows using approved detergents. Never use bleach or other harsh chemicals unless specified, as they can damage the pump and seals. Use only pressure washer safe soaps.
Where can I purchase replacement parts?
Original Hotsy parts are available through authorized dealers or online. Common spares: nozzles, spray tip, hose, pump oil, air filter, and spark plugs. Use genuine parts for warranty and performance.
How often should I change the pump oil?
Change pump oil after the first 50 hours, then every 500 hours or annually, whichever comes first. Use SAE 30 non-detergent oil. Overfilling can cause damage; check sight glass.
What is the warranty on the Hotsy 855?
Hotsy offers a limited 1-year commercial warranty on the unit. The engine and pump may have separate warranties (e.g., Honda 3-year). Retain your purchase receipt for warranty claims.
