TRACTOR
BREAK-IN
PROCEDURE
Never operate
a new engine
immediately
under
full load. Break it in carefully
as shown in the tablebelow.
5. Leave the throttle
in the slow
position
but
push the choke in all the way; then turn the ig-
nition
key to the start position
and slowly pull
the choke out to the position
which will cause
the engine
to start and continue
running.
If
the engine
falters
after
putting
tractor
into
motion,
pull the choke
out part way until the
engine
runs smoothly,
then
gradually
push
the choke back in as the engine warms.
OPERATING
IN COLD WEATHER
(682 and 782 Tractors)
While operating
tractors
equipped
with a 17 HP 2
cylinder
engine,
at light loads and usually
in low
temperature
conditions,
it is possible
to foul out a
spark plug. This will result in gasoline
entering
the
crankcase
by way
of the
piston
ri ngs
on the
cylinder
which
is not firing.
Some symptoms
are:
1. Oil level will rise due to gasoline
in crankcase.
2. Air filter becomes
oil and fuel soaked.
3. Engine leaks oil.
4. Mis-firing.
This condition
does not necessarily
mean that the
carburetor,
piston rings, ignition
coil-wires-points,
or gaskets
are defective.
Correction:
1. Replace
both spark plugs.
2. Check air filter element,
replace
if needed.
3. Change oil.
4. Adjust carburetor
if needed.
5. Service spark plugs regularly
when using trac-
tor under light duty or low temperature
condi-
tions.
COLD WEATHER
STARTING
Engine
starting
is possible
in cold weather
pro-
viding the correct
weight
of engine oil is used, the
battery
is fully charged,
and the proper
starting
procedure
is followed.
The
best procedure
for
starting
at temperatures
near or below freezing
is
as follows:
1. Pull the choke
all the way out into the full
choke position.
2. Move the throttle
lever just off "FAST"
posi-
tion.
3. Press the brake pedal all the way down and be
sure the power
take-off
switch
is in the off
position.
The safety
interlocks
will
prevent
starting
unless this is done.
4. Move the key switch
into the start position
and hold until the engine
starts; however,
do
not
operate
the
starter
for
more
than
30
seconds
at anyone
time.
As soon
as the
engine
starts,
slowly
push the choke
in part
way.
DRIVING THE TRACTOR
1. Depress the standard
brake pedal, release the
brake lock,
and let the pedal
up. Move the
throttle
lever to the position
where the engine
operates
best for the load to be handled.
2. Start
the tractor
in motion
by moving
the
speed control
lever slowly forward'or
rearward
to desired speed.
~ CAUTION
During
operation
do
not
run
the
engine
in confined
area
such
as
storage
building
any longer
than is
necessary.
Immediately
move
the
tractor
outside
into the air.
&
CAUTION
Avoid
sudden
starts,
excessivespeed,
sudden
stops.
Keep vehicle
in gear when going down hills.
NOTE:
In cold
weather
the starting
motor
maydisengage
prematurely.
This
is caused
by theengine
firing once but failing to continue
running.
If this happens
several times,
the engine
will be
flooded
and
it will
be necessary
to
start
as
described
in step 5.
NOTE: When using power take-off operated
equip-ment,
best performance
is achieved with the throt-
tle lever in the "FAST"
position.
