I have the John Deer 3800 psi from lowes. The machine is in great running order it just seems to be losing psi as I use it. Also checking the oil in the Honda 13hp motor and in the pump. Do you take the dipstick out and then insert it Not screw it back in to check the oil? The motor has 2 places for oil 1 on each side?

The Honda engine manual for the 3800 p.9 has the instructions for the ENGINE oil check and says to not screw in the dipstick when checking ENGINE oil. The John Deere operators manual for the 3800 has the instructions for checking PUMP oil but does not specify whether to screw the dipstick in or not when checking PUMP oil. The PUMP had oil already from the factory and, assuming the factory used the proper amount of oil, you need to screw in the PUMP dipstick to get a proper reading (otherwise it appears low). The PUMP takes about 12 oz of 30W NON-DETERGENT oil, so you could drain the oil and refill with 12 oz and then check the dipstick to see if the dipstick needs to be screwed in or not (probably my next step). Any manual that doesn't tell you whether to screw in a dipstick or not is DEFICIENT !!
