Safe Handling Of Gasoline:
To avoid personal injury or property damage use extreme care in
handling gasoline. Gasoline is extremely flammable and the vapors
are explosive. Serious personal injury can occur when gasoline is
spilled on yourself or your clothes which can ignite. Wash your skin
and change clothes immediately.
a. Use only an approved gasoline container.
b. Never fill containers inside a vehicle or on a truck or trailer bed
with a plastic liner. Always place containers on the ground away
from your vehicle before filling.
c. When practical, Remove gas-powered equipment from the truck
or trailer and refuel it on the ground. If this is not possible, then
refuel such equipment on a trailer with a portable container,
rather than from a gasoline dispenser nozzle.
d. Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do not
use a nozzle lock-open device.
e Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
f. Never fuel machine indoors because flammable vapors will
accumulate in the area.
g. Never remove gas cap or add fuel while the engine is hot or
running. Allow engine to cool at least two minutes before refuel-
ing.
h. Never over fill fuel tank. Fill tank to no more than ½ inch below
bottom of filler neck to provide for fuel expansion.
i. Replace gasoline cap and tighten securely.
j. If gasoline is spilled, wipe it off the engine and equipment. Move
unit to another area. Wait 5 minutes before starting the engine.
k. To reduce fire hazard, keep mower free of grass, leaves, or
other debris build-up. Clean up oil or fuel spillage and remove
any fuel soaked debris.
l. Never store the machine or fuel container near an open flame,
spark or pilot light as on a water heater, space heater, furnace,
clothes dryer or other gas appliances.

Adjust the side shields as shown in Figure 7, as you
adjust the depth stake. Be certain spark plug wire is
disconnected and grounded against the engine.
1. When using the tiller for the first time, use the
second adjustment hole from the top (1" of tilling
depth). See Figure 7.
2. When breaking up sod and for shallow cultivation,
use the setting which gives 1" of tilling depth
(second hole from the top). Place the side shields
in their lowest position. For further depth, raise the
depth stake and side shields and make one or two
more passes over the area.
3. When tilling loose soil, depth stake may be raised
to its highest position (use bottom adjustment
hole) to give the deepest tilling depth. Raise the
side shields to their highest position.
4. To transport tiller, lower the depth stake (use top
adjustment hole).
To adjust the depth stake, remove the clevis pin and
hairpin clip. See Figure 7. Move the depth stake to the
desired setting and secure with the clevis pin and
hairpin clip.
