When ordering parts from your Authorized Case Dealer and in
all contacts or correspondence with your dealer relative to the
tractor always specify the Serial, Model and Engine Numbers of
your tractor.
The Tractor Model and Serial Numbers are stamped on the
number plate located on the instrument panel, Figure 6. The En-
gine, Model, Serial and Engine Specification Numbers are stamped
on a plate fastened to the right or upper front side of the engine,

FUEL CONDITIONER
The following "Fuel Conditioner’ recommendations are made for
areas troubled with gum and varnish in the fuel:
1. Obtain "Case Lubra-Gas Conditioner" and use it as follows:
A, Add it to the fuel in the main storage container in pro-
portions specified on the label,
B. Add a small quantity to the tractor fuel tank daily.
С. Use the "Conditioner' periodically, or when any symptoms
develop in the engine that indicate gum and varnish deposits
in the Fuel System,
NOTE
Refer to the instructions furnished with
the "Conditioner" as to the amount that
should be used.

Selection of Lubricating Oil
It is extremely important that you select and use in your Case
Tractor Engine a detergent type, high quality, SD or CC API Service
Classification Oil for model 220, 222, 224 and 444.
Use SE or SE/CC API Service Classification Oil for model
446. Do not use Service DS oil. Do not mix brands nor grades
of oil.

REGULAR OIL CHANGE
Drain and refill the crankcase at least every 25 hours of opera-
tion. (50 hours for model 446)
If possible, run engine just prior to changing oil--the oil will
flow more freely and carry away a greater amount of contaminan
when hot. ©
If the engine service is severe-(frequent stopping and s g,
high or low operating temperature)-the crankcase should be ©

warm up a col draulic system is to position the High-
Low Range Shift Lever in neutral and place the Travel
Control Lever in Forward or Reverse to circulate the
oil through the hydraulic motor.
-15-
4, HIGH - LOW RANGE SHIFT LEVER - When shifting into Low or
High Range, make certain the lever is located past the neutral
locking pin, Likewise, when shifting to neutral, the lever must
be locked to the pin, Gear damage can result if the tractor is
operated while the shift lever is not fully engaged beyond the
locking pin,
‚5. TRAVEL "CUSHION" CONTROL LEVER - This single lever pro-
vides effortless and smooth "finger-tip Cushion Control’ of speed
and travel direction, Move the lever forwardas desired to obtain
either full speed ahead or to "creep" through heavy grass or
deep snow, For reverse, simply move the lever rearward,
Thus the tractor ground travel speed may be regulated in-
dependently of engine RPM. Depress the lever slightly when
moving to either direction for smoother motion and control,
NO TE The travel control lever quadrant has an anti over-run
detent on each side of the neutral detent, See figure 14.
Put the lever in these positions when a very slow speed
is desired or when operating on an incline to prevent the
tractor from over-riding the oil flow, and running free.

The travel control lever can be used in lieu of the brake

the speed control lever will be automatically returned to
neutral, Again, keep in mind that the travel lever can
be moved into forward or reverse while your foot is
still on the brake,
7. HEADLIGHTS - The headlights are turned on when the ignition
key is turned to the "Light" position after the engine is started.
Do not operate the headlights unless the engine is running ©
the Generator Warning Light is off.
Figure 15.

8. AMMETER - 446 only - When the engine is started and running
the ammeter will gradually fall back as the battery becomes
charged. If a no charge or discharge rate is indicated with a
freshly started engine or when operating with the lights on
and engine above half throttle, stop the engine immediately
and have the cause corrected.
9. GENERATOR WARNING LIGHT - 220 thru 444 - The Warning
Light goes on when the key switch is turned on and should go
off when the engine starts, If the warning light does not go off
when the engine is running, it is an indication that the battery
is discharging and the generator is not supplying current.
STOP THE ENGINE AND CHECK FOR THE CAUSE.
NOTE ı: the Warning Light flickers when the engine is at low
idle, the battery, generator or regulator may not necessarily
require servicing, However, if the Warning Light remains
on when engine speed is increased, stop the engine im-
mediately and have the cause corrected.

RUN-IN PROCEDURE
Your new tractor should be subjected to a run-in period before
it is operated at full load. Drive the tractor for approximately an
hour to get the feel of operation. Actuatethe travel control through

PRE-STARTING CHECK LIST
Before starting your new Case Tractor for the first time and be-
fore each operating period thereafter, check the following.
1. MAKE SURE EVERYONE RESPONSIBLE FOR THE TRACTOR'S
OPERATION AND MAINTENANCE UNDERSTANDS THE IMPOR-
TANCE OF CLEAN FUEL, OILS, CONTAINERS AND FUNNELS.

AIR CLEANER
Remove and clean element after each 25 hours or weekly.
Install new element every 500 hours or yearly or when loss of
power is noticeable.
Tap element lightly on a flat surface to cause the loose dirt to
fall off. Handle the element with care to avoid damage.
Replace the element with a new one if dirt does not drop off
easily or if it is damaged. When replacing the element, be sure it
fits snugly around the inside edge of the air cleaner base. Then
replace the cover and tighten the wing nut finger tight.
An optional precleaner, Case part number K0237421, is available
and will extend the life of the air cleaner element.

CARBURETOR ADJUSTMENTS Model 446
The carburetor has a main fuel (high speed) adjustment and a
idle fuel adjustment. The main adjustment affects operation under
heavy load conditions. Idle adjustment affects operation under
light or no load conditions. Under normal circumstances, factory
carburetor adjustments should not be disturbed. If the adjustments
have been disturbed, turn needles off their seats, 7/8 to 1-1/8
turns to permit starting. Then, readjust them for smooth Operation.
Forcing the needle against its seat
will damage it. The needle does
IMPORTANT not completely shut off fuel when
turned fully in.
Before final adjustment, allow the engine to warm up. Make
the idle adjustment under no load. Open the main jet until the
engine runs smooth under acceleration with no load. Slightly
more fuel may be needed (open about 1/4 turn further) when sudden
load is applied.
Set the throttle stop screw (located on carburetor throttle
lever) with no load connected and while running at a low speed
setting. Turn the screw to give approximately 1 /32 inch clearance
between the screw and pin.
If the engine develops a "hunting" condition (alternate in e
and decrease of engine speed), try correcting by opening th ino
adjusting needle a little more. Do not open more than
beyond the maximum point of power,

NOTE
It is possible that under unusual conditions, "colder" type spark plug
may be required. Consult your Authorized Case Dealer regarding
the proper type spark plug to use for your particular condition.
The spark plug plays a very important part in the power, fuel
economy and general performance of your engine, The outside of
the plug should be cleaned frequently to prevent shorting of the plug.
The spark plug should be removed, checked, cleaned and gapped
at the end of every 100 hours of operation.

Place front wheels in a straight ahead position,
2. Make sure the front tire pressures are equal,
3. The front tires should show a mold part-line which coincides
with the centerline of the tire, If the centerline of the tire is
not readily visible then the wheel can be raised off the ground,
Spun and marked at the approximate centerline location,
