The transmission was filled with gear oil at the factory. However,you should check the gear oil levelto makecertain it is correct.

IMPORTANT:Do not operate the tiller if the gear oil level is low. Doing so will result in severe damageto the transmis- sign components.

1.Put the tiller on levelground. Pullthe DepthRegulator Lever (FF, Fig. 2-10) backand then adjust it up or down to the notch that makesthe tiller level.

2.Removethe oil fill plug (GG,Fig. 2-11) from the transmission housing and look into the oil fill hole. You will see the main drive shaft on oneside of the hole.

3.The gear oil level is correct if the gear oil is approximately halfway up the side of the drive shaft.

4.If the gear oil level is low, add gear oil by referring to "A. To Checkthe Transmis- sion GearOil Level" in Section 5.
