diately for the cause. Vibration is gener-
ally a warning of trouble.
6. Stop the engine, disconnect the spark
plug wire and prevent it from touching the
spark plug, whenever you leavethe oper-
ating position, before unclogging the tines,
or when making any repairs, adjustments
or inspections.
7. Take all possible precautions when
leaving the machine unattended. Stopthe
engine. Disconnectthe spark plug wire
and move it away from the spark plug. Be

odorless, colorless, and tasteless.
12. Keepchildren and pets away.
13. Never operatethe tiller under engine
powerif the wheels are in the Freewheel
position. In the Freewheel position, the
wheels will not hold the tiller back and the
revolving tines could propel the tiller
rapidly, possibly causing loss of control.
Always engage the wheels with the wheel
drive pins in the Wheel Drive position
before starting the engine or engaging the
tines/wheels with the Forward Clutch Bail
(all models) or the ReverseClutch control
(Models 634F/634B only).

if the tines shouldstrike extremely hard
packedsoil, frozenground,or buried
obstacleslike large stones, roots, or
stumps.If in doubt aboutthe tilling con-
ditions, always use the following
operatingprecautionsto assistyou in
maintainingcontrolof the tiller:
a. Walk behindand to one side of the
tiller, using one handon the han-
dlebars. Relax your arm, but use a
secure hand grip.
b. Use shallower depth regulatorset-
tings, workinggradually deeper
with each pass.
c. Use slower engine speeds.
d. Clear the tilling area of all large
stones, rootsand otherdebris.
e. Avoid using downwardpressureon
the handlebars.If need be, use
slight upwardpressureto keepthe
tines from diggingtoo deeply.
f. Beforecontactinghard packedsoil
at the end of a row, reduceengine
speed and lift the handlebarsto
raise the tines out of the soil.
g. In an emergency,stopthe tines and
wheels by releasingwhichever
clutchcontrolis engaged. Do not
attempt to restrain the tiller.
15. Do not overload the tiller's capacity by
attempting to till too deeply at too fast a
rate.
16. Never operate the tiller at high trans-
port speeds on hard or slippery surfaces.
Look behind and use care when backing
up.
17. Do not operate the tiller on a slope
that is too steep for safety. When on
slopes, slow down and make sure you

the governor controls the maximum safe
operating speed to protect the engine and
all moving parts from damagecaused by
overspeed. Authorized service shall be
sought if a problem exists.
24. Do not touch engine parts which may
be hot from operation. Let parts cool down
sufficiently.
