how do I add oil to pressure pump?
1 answer-

There is a cap marked OIL on top of the crankcase. Remove the cap and add oil as needed. Only use a SAE 30 non-detergent oil. Please view item 22022 for compatible pump oil.

I see this unit comes with 5/16in. x 25ft. Uberflex nonmarking hose. Will a standard 1/4" hose of a different brand work? Will MTM quick connect M22 and M14 couplings work with the unit?
1 answer-
NorthstarExpert7· 5 years ago
The uberflex hose has standard quick connect fittings. A hose of a different brand can be used. An adapter would have to be used to be compatible with a different hose connection.
