Knowledgebase: Gas Pressure Washer
Do I add oil to the engine of my gas pressure washer before using it the first time?
Yes. Kärcher pressure washers do not ship with engine oil already in the crankcase. Oil must be added to the engine before starting. There may be a small residue of oil from testing the engine but it is not enough to effectively operate the machine. Please refer to your engine owner's manual to find the correct amount and grade of oil required. Also, be sure to use the oil supplied with the pressure washer.

If oil is not added, severe damage will be caused to the engine. The engine can lock up and no longer turn. Therefore, add engine oil before operating the first time!

Please note while you MUST add oil to the engine, you do NOT need to add oil to the pump. Only the engine requires oil before staring your gas pressure washer the first time.
