Prepare your snowblower for the oil change. Remove the ignition key. Block the wheels with wood blocks or rocks to prevent movement while being serviced. Place a drain pan below the oil plug to retain used oil.
Drain the oil. Remove the filler cap. Remove the drain plug with the 10mm wrench included in the machine's tool kit. Allow the used oil to drain completely into the drain pan. Replace the drain plug and tighten it securely.
Fill the crankcase with motor oil. Ensure the oil is the amount and weight specified in the owner's manual. Check oil with the dipstick to ensure that it is filled to the proper level. Replace the filler cap and tighten it securely.
Properly dispose of the used motor oil. Place the oil in a sealed container and bring it to your nearest recycling center or service station. Never discard oil in the trash, pour it down the drain or spill it on the ground.
Perform scheduled oil maintenance. Check the oil level after each use. Change the oil after the first 20 hours of operation or once a year before operation, whichever comes first.
