Hi, not sure where to post this, I have a ryobi pressure washer and looking for some imformation on the pump , what sort of maintenence should be done on the pump itself ? It's a chonda motor and has been sitting for a few years so it needed a carby clean and a change of oil. Motor is running good. Can I run the motor without water in the pump or will this destroy the pump. I noticed the pump had a label to use sae. 85w90. Thankyou. [Linked Image]
