To change the oil on your Craftsman 625, begin by placing the lawnmower on a surface that you do not mind spilling oil onto in the case of spilling some.
First of all, you should remove any fuel which is already in the engine. The easiest way to do this is to simply allow the fuel to run out while you are using your lawnmower. For safety purposes you should disconnect the spark plugs. The oil drain plug for the Craftsman 625 series lawnmower is located on the bottom of the mower, just above the blade. Tip the mower back. The plug is round and threaded with a square head. Using the square head of a ratchet extension, twist the plug counter clockwise and remove. The oil will start draining out so place a container underneath it to collect the old oil. Once it has drained, replace the plug and tighten clockwise until snug. Replace with new lawnmower oil or SAE-30 weight oil. Many people forget how important it is that basic maintenance should be performed on a lawnmower at regular intervals. To keep the engine running in top condition, you need to change your lawn mower oil fairly often. It’s not a difficult process and only takes a few minutes to complete. Check with the manual how often you will need to change the oil and it will usually vary from between 25-50 hours of use. If you have recently bought a lawn mower, the oil needs to be changed after the first five to eight hours of use. This is to get rid of any metal shavings or debris that might have been left in your machine during manufacturing and assembly.
Never tip your machine with the carburettor or spark plug down. The oil will saturate the air filter and cause hard starts or cause the mower not to start at all. If you do accidentally contaminate the air filter, it will need to be replaced. Drain the oil through the dipstick tube into a container. Allow sufficient time for all oil to drain. Dispose of the drained oil properly.
