Checking Oil

WARNING: To prevent extensive engine wear and damage to the unit, always maintain the proper oil level in the crankcase. Never operate the unit with the oil level below the bottom of the dipstick.

•Stop engine and allow oil to drain into the crankcase.

•Lay the cultivator back in a horizontal position on a flat level surface with the upper handle touching the ground.

•Keep dirt and debris out of the engine. Clean the area around the oil fill plug/dipstick before removing it.

•Remove the oil fill plug/dipstick and wipe off oil. Reinsert it all the way back in.

•Remove the oil fill plug/dipstick and check oil level. Oil should be up to the top of the dipstick.

Refer to Figure 3.

•If the level is low, add a small amount of oil to the oil fill hole and recheck. Repeat until the oil level reaches the top of the dipstick. See Figure 8.
