Section 5: Maintenance
WARNING
Before inspecting, cleaning or servicingthe unit, shut off engine, wait for all
parts to come to a completestop, disconnectspark plug wire and move wire away from spark
plug.
Failure to follow these instructions can result in serious personal injury or
propertydamage.
B. To Drain the TransmissionGear Oil:
DANGER
Gasoline is highly flammable
and its vapors explosive. Fol-
low these safety practices to
prevent
injury or property
damage from fire or explosion.
,, 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 gear oil does not need
to be changed unless it has been contam-
inatedwith dirt, sand or metal particles.
1. Drain gasoline from the fuel tank or
run the engine until the fuel tank is empty.
See "DANGER"statement above.
2. Drain the oil from the engine.
3. Removethe four screws (B, Figure5-2)
and washersfrom the transmission cover
and remove the cover and gasket.
4. Removethe left-side wheel.
5. Tilt the left-side wheel shaft into a
drain pan and allow the gear oil to drain
through the top of the transmission.
6. After draining oil, reinstall the wheel,
install a new gasket (do not reuse old
gasket) and screw on transmission cover.
7. Refill transmission using GL-4 gear oil
(SAE85W-140 or SAE 140).
8. Refill the engine with motor oil and
replenishthe fuel tank with gasoline.

TINES
The tines wear with use and they should
be inspected at the beginning of each
tilling season and after every 30 operating
hours. The tines can be replaced individ-
ually or as a complete set. Refer to the
Parts List Section of this manual for 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 run backward.
Failure to comply could result
in personal injury or property
damage.
NOTE:You must first remove the tiller
hood before removing either a single tine
holder or individual tines. Removethe
two screws at the front of the hood and
the two screws at the rear of the hood
and lift off the hood. Be sure to replace
the hood securely after changing a tine or
tine holders.
A. Tine Inspection:
With use, the tines will become shorter,
narrower and pointed. Badly worn tines
will result in a loss of tilling depth and
reducedeffectiveness in general, and
specifically when chopping up and
turning under organic matter.
B. Removingand Installing
Tine Assemblies
1. Use a 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. Use a rubber mallet to tap the tine
holder loose. Slide tine assembly off.
3. RepeatSteps 1 and 2 aboveto remove
the other tine assembly.
4. Installing the tine assembly is simply
the reverse of its removal. First be sure
to remove any rust, unevenspots or burrs
from the tine shaft using fine sandpaper.
Then greasethe tine shaft before rein-
stalling the tine assemblies. Be sure all
the cutting edgesface so they will enter
the soil first when the tiller is moving
forward- this meansthe cutting edge on
the top of each tine faces towardthe
operator position. Tighten hardware.
C. Removingand Installing
IndividualTines
1. Use two 9/16" box end wrenchesto
remove the two screws (C, Figure 5-3)
and nuts (D) that secure the 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 reverse order from which they were
removed. The two sets of inboard tines
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 be sure the cutting edge at the top
of each fine faces toward the operator
position. (See Figure 5-3.)
