UNDER NO CIRCUMSTANCES SHOULD YOU ATTEMPT TO
SERVICE THESE UNITS YOURSELF. Only your dealer
is authorized to repair or replace units on the
hydrostatic drive under the terms of the
warranty. You cannot start the engine by towing
the tractor, attempts to do so will damage the
hydrostatic motor. To tow the tractor, place the
High-Range Selector in neutral. Refer to "Towing
Tractor". Never attempt to effect a high speed
coast by putting the speed ratio control lever in
neutral or by depressing the Foot-N-Inch
pedal. Never coast the tractor with the engine
shut- off. Change the filters at the specified
inter- val. The 10 hour and 100 hour changes are
extremely important and must not be over- looked.
A variety of optional equipment is avail- able.
Refer to "Oplionol Equipment". Operating and
maintenance instruction on these items is inc
luded in the ir.structions for operating or
maintaining the tractor. Disregard in-
structions for equipment not on your tractor.
These are a few facts that you should know about
your hydrostatic drive tractor. The hydrostatic
drive will require mini- mum service if
recommended operating and maintenance procedures
are followed. Should you have difficulties with
the unit consult your International Harvester
dealer.

WORK SAFELY FOLLOW THESE RULES
TO i s symbo I i s u sed to col I your attention
to in sfruc ti on s con cernin g your personal
safety. Be sure to observe and fol low these in
struction s.
BEFORE STARTING
Bet ore starting engine make sure helpers or
observer s stand clear of equipment. Operate the
engine only in well ventilated areas. Release
park brake completely.
A Careful operator i s the besf insurance again
st on occident.
Know the controls and what they do. When fueling
an engine, keep any type of open flame away. Do
Not Smoke ! Wait for the engine to cool before
refueling it. Check brake s and clutch for
correct ad- justment s. Reduce tipping hazards by
spreading wheels as far as your work program per-
mits. Check coolant and engine oil levels, and
perform any other necessary services, be- fore
starting the engine. Clean dirt, trash, and
grease f rom oper- ator's platform, pedals,
steps, and steering wheel. Be sure muffle r and
exhaust pipe exten- sions are in place so exhaust
gases are dis- charged above operator. Alway s
earry a Charged fire extin- guisher and a first
aid kit. Avoid loose-fitting clothing, which
could catch on moving parts.
DURING OPERATION
Power take- off master shield must always be in
place on the tractor.
Use the drawbar in lowest position when hitching
to a heavy load, such as manure spareade rs,
loaded two- wheel trailers, and heavy wagons.
Pull only f rom drawbar never hitch to axle
housing.
Shift transmission to neutral and set park brake
before dismounting to hitch equipment.
Keep safety shields in place when using power
take- off.
Disengage PTO and shut off the engine before
adjusting or unc logging power driven machinery.
Mounting assist handles and steps are provided
for your safety. Use them when getting on or off
the tractor.
Only the operator should ride on the trac- tor.
He should sit on seat or stand on the platform.
Put all controls in neutral bef ore start- ing
the engine. Be sure power take- off lever is in
the OFF or disengaged position before start-
ing engine.
Keep others, especially children, from riding
on steps, fenders, or drawbar, and away from
tractor and equipment.

WORKSAFEY-FOLLOWTHEERULES
DURIHG OPERATION - Continued
TRANSPORTING
Reduce speed when traveling on rough roads. Avoid
heavily-traveled roads when moving equipment, if
at all possible. Use warning devices (i. e. ,
flags, S.M.V. emblem, lights, etc. ) which are
approved for use by your local government
agencies, when moving equipment on public
roads. Keep these devices clean and in good work-
ing condition. Be sure hitches and/or drawbars
are properly stabilized before towing
equipment. When moving on public roads, or f rom
field to field, lock brake pedals together for
simultaneous operation when making a stop. Be
courteous, have consideration for other traffic
using the road.
Reduce speed before making a turn.
Always keep the tractor in gear when going down
steep hills.
Avoid ... sudden starts, excessive speed, and
sudden stops ... when operat- ing on hillside,
rough ground, and most off- the- road operations.
Carefully supervise inexperienced oper- ators.
Stop the engine before leaving the tractor.
TRACTORSWITHCABS
AFTER OPERATING
Be sure cab doors are securely latched, either
closed or open, when operating the tractor.
Wait for tractor to STOP before dis-
mounting. Lower equipment to ground before leav-
ing tractor. Shut off engine and remove ignition
key. Lock the park brake so tractor will not roll.
Always use the seat belts, if they are furnished
with the unit. However, do not install seat belts
if the tractor has no pro- tective frame.
Adjust rear view mirrors Ior maximum vision.
To remove the radiator cap when the en- gine is
hot, turn the cap to the pressure re- lease point
- let pressure and steam es- cape - then remove
it.
Lock the cab doors, if locks are fur- nished,
when leaving the tractor.

AIR CONDITIONER CONDENSER This unit, located at
the top rear of the cab, is equipped with a
vertical f inned core assembly which is
self-cleaning in opera- tion. In operation turn
air conditioner off momentarily and accumulated
chaff, etc. on lower face of condenser fins will
be jarred loose by vibration of the tractor. When
air conditioner is again turned on it will
operate at increased cooling eff)ciency.
Periodically as required, the condenser fins may
be blown clean with air or flushed with water to
fully renew cooling efficiency.

Be sure sight glass is clean.
If the sight glass is cloudy, with many bubbles,
