Note: Recommended oil to use in the future is 10W-30,with
a minimum classification of SF/SG), a dded to the unit until
the oil level registers between high (H) and low (L) on the
dipstick.
Note: Do not overfill. Overfilling with oil may result in
engine smoking, hard starting or spark plug fouling.
Replace and tighten the fill cap/dipstick firmly.
Checkingthe OilBefore EachUse
NOTE: Be sure to check the engine on a level surface with the
engine stopped.
1. Remove the oil filler cap/dipstick and wipe the dipstick

3. Remove the oil filler cap/dipstick. If the level is low, slowly
add oil (10W-30, with a minimum classification of SF/SG)
until oil level registers between high (H) and low (L).
Note: Do not overfill. Overfilling with oil may result in
engine smoking, hard starting or spark plug fouling.
4. Replace and tighten cap/dipstick firmly before starting
engine.

Transmissi0n/Gear Oil
The transmission was filled with gear oil at the factory. However,
you should check the gear oil level at this time to make certain it
is correct,
NOTE: Do not operate the tiller if the gear oil level is low. Doing
so will result in severe damage to the transmission components.
1. With the tiller on level ground, pull the Depth Regulator
Lever back and then all the way up until the lowest notch in
the lever is engaged. See Fig. 3-5.
