STEP 6: CHECK TRANSMISSION
OIL LEVEL
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.
IMPORTANT: Do not operate the tiller if the
gear oil level is low. Doing so will result in
severe damage to the transmission com-
ponents.
1. With the tiller on level ground, pull the
Depth Regulator Lever (FF, Fig. 2-10) back
and then all the way up until the lowest
notch in the lever is engaged.
2. Remove the oil fill plug (GG, Fig. 2-11)
from the transmission housing cover and
locate the main drive shaft situated inside
the housing.
3. The gear oil level is correct if the gear oil
is approximately halfway up the side of the
main drive shaft.
4. If the oil level is low, add gear oil by re-
ferring to A. To Check the Transmission
Gear Oil Level in Section 5.
STEP 7: ADD MOTOR OIL
The tiller is shipped without oil in the en-
gine.
IMPORTANT: Do not start the engine with-
out first adding motor oil. Severe engine
damage will result if the engine is run with-
out oil.
1. Refer to the separate Engine Owner’s
Manual for engine oil specifications and
capacities.
2. With the tiller on level ground, move the
Depth Regulator Lever (FF, Fig. 2-10) up or
down until the engine is level.
3. Add motor oil as described in the En-
gine Owner’s Manual.
4. Move the Depth Regulator Lever all the
way down until the highest notch is en-
gaged. This places the tines in the “travel”
position, which allows the tiller to be
moved without the tines touching the
ground.
STEP 8: CHECK HARDWARE
Check all nuts and screws for tightness.
STEP 9: CHECK AIR PRESSURE IN
TIRES (units with pneumatic tires)
Check the air pressure with a tire gauge.
Deflate or inflate the tires equally to be-
tween 15 PSI and 20 PSI (pounds per
square inch). Be sure that both tires are in-
flated equally or the unit will pull to one
side.
