1. Low-pressure oil common fault check and eliminate (1) there is no fuel tank or fuel too little. Check the amount of fuel in the fuel tank, add less. (2) oil pump into the small end of the filter is blocked by dirt, so that poor fuel supply. Clean oil pump into the oil side of the small filter, damaged should be replaced. (3) pump into the oil valve is pad or stuck, resulting in lax seal. Remove the oil pump, remove the oil pump inlet and outlet valves, check whether the pad or stuck, and check the sealing surface is flat, if necessary, repair the sealing surface or into the oil valve.
