If your engine recoil starter rope is hard to pull, it may be due to “pressure lock” of the pump. Pressure lock is caused by:
This pressure can prevent the engine from moving and the engine recoil starter rope from being pulled, acting like the engine is locked up.
If the recoil cannot be easily pulled, possibly due to pressure lock, then squeeze the spray gun trigger to relieve built up pressure on the pump and engine. Failure to release the pressure built up in the high-pressure hose may lead to the engine continuing to behave as if it is seized or locked up. Once you have relieved the pressure, try to start the engine again.

No, only use the cold-water hose bib or spigot on your house with the pressure washer. Cold water helps to cool the pump. Hot water can damage a cold-water pressure washer pump.
