Frequently Asked Questions - CM61235 Simpson
What type of oil should I use in the Simpson CM61235 engine?
Use SAE 10W-30 engine oil for general conditions. For warmer climates, SAE 30 is acceptable. Always check the oil level before each use.
How do I start the pressure washer?
Ensure fuel and oil are full. Turn the fuel valve ON, set the choke to CLOSE, squeeze the trigger gun to release pressure, then pull the starter rope firmly. Once warm, open the choke.
Why is my pressure washer not building pressure?
Possible causes: air in the system (squeeze trigger to purge), clogged nozzle (clean with a pin), low water supply, or worn pump packing. Check inlet filter and hose for kinks.
How often should I change the pump oil?
Change the pump oil after the first 50 hours of use, then every 100 hours or annually. Use SAE 30 non-detergent oil or pump oil specifically for pressure washers.
Can I use bleach or other chemicals in the soap nozzle?
Only use pressure washer-safe detergents. Bleach and harsh chemicals can damage the pump and seals. Rinse the soap system with fresh water after each use.
What size extension cord can I use for the electric start (if applicable)?
The CM61235 is typically recoil start only. For electric start models, use a 12-gauge or heavier cord no longer than 50 feet to avoid voltage drop.
How do I store the pressure washer for winter?
Remove all water from the pump by running it briefly without water inlet connected. Add pump saver/antifreeze, drain fuel, change oil, and store in a dry place above freezing.
The engine runs but the water pressure is low. What should I check?
Check the inlet water supply (≥ 1 gallon per minute), ensure hose is not kinked, clean the inlet filter, and inspect the nozzle for debris. Also verify the unloader valve is not stuck.
Where can I find replacement parts for my Simpson pressure washer?
Authorized Simpson dealers and online retailers carry parts. You can find pump repair kits, hoses, trigger guns, and nozzles. Use the model number CM61235 for correct fit.
What does the thermal relief valve do?
It automatically opens to discharge hot water when the pump reaches a critical temperature during bypass mode, preventing damage to pump seals.
