B. To Drain the TransmissionGear Oil:
DANGER
Gasoline is highly flammable
and its vaporsexplosive. Fol-
low these safety practices to
prevent injury or property
damage from fire orexplosion.
• Allow the engine and
muffler to cool before
draining the tiller's gasoline
tank.
• Do not allow open flames,
sparks, matches or smoking
in the area.
• Wipe away spills and push
tiller away from spilled fuel.
• Use only an approved fuel
container and store it safely
out of the reach of children.
• Do not store gasoline where
its vapors could reach an
open flame or spark, or
where ignition sources are
present (such as hot water
and space heaters, furnaces,
clothes dryers, stoves,
electric motors, etc.)
The transmission gearoil does not need
to bechanged unless it has beencontam-
inated with dirt, sand or metal particles.
1. Drain gasoline from the fuel tank or
run the engineuntil the fuel tank is empty.
See"DANGER"statement above.
2. Draintheoil from the engine.
3. Removethe four screws (B, Figure 5-2)
and washersfrom the transmission cover
and remove the cover and gasket,
4. Removethe left-side wheel.
5. Tilttheleft-side wheel shaft intoa
drain panand allow the gear oil to drain
through the top of the transmission,
6. After draining oil, reinstall the wheel,
install a newgasket (do not reuse old
gasket) and screw on transmission cover.
7. Refill transmission using GL-4 gearoil
(SAE85W-140 or SAE140).
8. Refill the engine with motor oil and
replenish the fuel tank with gasoline.

TINES
Thetines wear with useand they should
be inspected at the beginning of each
tilling seasonand after every30 operating
hours, The tines can be replaced individ-
ually or as a complete set, Referto the
Parts List Section of this manualfor tine
identification information.
WARNING
This is a CRT (counter-rotating
tine) tiller and its tines must
be mounted in the direction
shown in Figure 5-3. If
mounted with curves in the
opposite direction, tiller will
dig poorly and be more likely
to runbackward.
Failure to comply could result
in personal injury or property
damage.
NOTE:You must first remove thetiller
hood before removing either asingle tine
holder or individual tines, Removethe
two screws at the front of the hood and
the two screws atthe rear of the hood
and lift off the hood, Besure to replace
the hood securely after changinga tine or
tine holders.
A. Tine Inspection:
With use, thetines will becomeshorter,
narrower and pointed, Badly worn tines
will result in a loss of tilling depth and
reduced effectiveness in general,and
specifically when chopping up and
turning under organic matter,
B. Removingand Installing
Tine Assemblies
1. Usea 9/16" socket,6" extension, a
ratchet, and a 9/16"box end wrench to
loosen the nut (A, Figure 5-3) and screw
(B) that secure the tine holder to the tine
shaft.
2. Usea rubber mallet to tap thetine
holder loose. Slidetine assembly off,
3. RepeatSteps1 and 2 aboveto remove
the other tine assembly.
4. Installing the tine assembly is simply
the reverseof its removal, First be sure
to remove any rust, uneven spots or burrs
from the tine shaft using fine sandpaper,
Then grease the tine shaft before rein-
stalling the tine assemblies, Be sure all
the cutting edges faceso they will enter
the soil first when the tiller is moving
forward- this means the cutting edge on
the top of each tine faces toward the
operator position, Tighten hardware.
C. Removingand Installing
Individual Tines
1. Usetwo9/16" box end wrenches to
remove the two screws (C, Figure5-3)
and nuts (D) that securethe tine to its
tine holder,
NOTE:If the nuts are rusted, apply pene-
trating oil, then loosen the hardware.
2. When installing individual tines, do so
in the reverseorder from which they were
removed, Thetwo sets of inboardtines
are installed so one set faces toward the
transmission and the other faces away
from it, The single outboardtine set
faces toward the transmission housing.
Also besure the cutting edge at the top
of eachtine faces toward the operator
position. (SeeFigure5-3.)
