keep your forearm parallel to the ground to
reduce the risk of hot oil dripping down your
arm.

this purpose that is large enough to hold the
full amount of oil in your engine.

reach of children.

the skin may cause skin damage. Always
wash oil off immediately with soap and wa-
ter to protect your skin.
