‘Traction’ which means pulling.
A Tractor is required to pull or haul an equip-
ment, implement or trolley which are coupled
to the Tractor body through suitable linkage.

as it has a power outlet source which is also
called Power Take or PTO shaft.
In this book the operating, maintenance and
storage instructions for all models of TYM
Diesel Tractors has been complied.
This material has been prepared in detail to

ferential in the front axle where the power is
divided into right and left and to the respec-
tive nal cases.
In the nal cases, the transmitted revolution
is reduced by the level gears to drive the front
wheel. The 4WD mechanism with level gears
provides wider steering and greater durability.

SAFETY PRECAUTIONS
Roll Over Protective Structures
(ROPS)
TYM Tractors are equipped with a frame for
the protection of operators.
In the case of cab tractors the frame is incor-
porated in the cab structure.
The objective of the frame or cab structure is
to protect the operator in the event of a roll
over and they are designed to support
the entire weight of the tractor in that event.
Each TYM ROPS frame or cab structure is
designed and has been tested to meet industry
and or Government standards.
Included in these tests were all mounting bas-
es and bolts or other fasteners.
On some models the ROPS frame has a
fold down feature, which can be used to
enter low buildings etc Take care when
lowering
the upper section of the ROPS frame and
take extreme care while driving the trac-
tor with the ROPS frame lowered.
Do not wear the seat belt with the ROPS
lowered and please remember that the
fold down facility is for special circum-
stances
only and must not be lowered for general
use.
Use of the tractor with the ROPS low-
ered can cause fatal injuries.
As the ROPS frame or cab together with the
seat belt was designed to meet certain stan-
dards, they must be maintained in good
order and condition. To achieve this objective,
both the structure and the seat belt should be
inspected on a regular basis (every
time the tractor is serviced)
In the event that the seat belt is damaged or
frayed, it should be replaced and in the event
that the ROPS frame or any part of the
mounting structure is damaged or cracked,
the faulty component must be replaced with a
new unit. Such a unit must meet all of
the test criteria of the original unit .Fitment of
an inferior item or items affects the certica-
tion of the entire ROPS structure and
the effectiveness of the structure in the event
of an accident. Drilling or welding of the
ROPS structure is forbidden.
(ROPS) Roll Over Protective Structures
• For ROPS frames to be effective
and protect the operator, the seat
belt provided must be worn in order
to keep operators within the ROPS
protected area in the event of a roll
over. Failure to use the seat belt can
still cause serious injury or death.

- 11
SAFETY PRECAUTIONS
Damage of the ROPS
If the tractor has rolled over or the ROPS has
damaged (such as striking an overhead object
during transport), It must be replaced to pro-
vide the original protection. After an accident,
check for damages to the 1.ROPS.2.Seat
3.seat belt & seat mountings. Before you op-
erate a Tractor, replace all damaged parts.
Before operating a Tractor it is important to
adjust the seat to the most comfortable posi-
tion & check whether it is properly locked in
its position. Figure 1 identies the seat tted
to your Tractor.
(Cabin type) (Roll-bar type)
•DO NOT WELD, DRILL OR-
STRAIGHTEN THE ROPS
• Never attach chains, ropes to the
ROPS for pulling purposes; this
will cause the Tractor to tip back-
wards. Always pull from the Tractor
drawbar. Be careful when driving
through door opening or under low
overhead objects. Make sure there is
sufcient overhead clearance for the
ROPS fatal injuries
• Always wear your seat belt if the
tractor is equipped with ROPS
• If the ROPS is removed or replaced,
make certain that the proper hard-
ware is used to replace the ROPS
and the recommended torque values
are applied to the attaching bolts
• Do not use solvents to clean the seat.
Use warm water with a little deter-
gent added.

SIGNAL WORDS.
A signal word―DANGER, WARNING OR
CAUTION―is used with safety alert sym-
bol. DANGER identies the most serious
hazards. Safety signs with signal Word ―

SAFETY PRECAUTIONS
USE OF ROPS AND SEAT BELT
The Roll Over Protective Structure(ROPS)
has been certied to industry and/or govern-
ment standards. Any damage or alternation to
the ROPS, mounting hard-ware, or seat belt
voids the certication and will reduce or elim-
inate protection for the operator in the event
of a roll-over. The ROPS, mounting hard-
ware, and seat belt should be checked after
the rst 100 hours of Tractor and every 500
hours thereafter for any evidence of damage,
wear or cracks. In the event of damage or al-
teration, the ROPS must be replaced prior to
further operation of the Tractor.
The seat belt must be worn during machine
operation when the machine is equipped with
a certied ROPS.
Failure to do so will reduce or eliminate pro-
tection for the operator in the event of a roll
over.
PRECAUTION TO AVOID TIP-
PING
Do not drive where the Tractor could
slip or tip.
Stay alert for holes and rocks in the ter-
rain, and other hidden hazards.
Slow down before you make a sharp
turn.
Driving forward out of a ditch or mired

Stop the engine and remove the key
KEEP RIDERS OFF TRACTOR
Do not allow riders on the Tractor.
Riders on Tractor are subject to injury such as
being stuck by
foreign objects and being thrown off of the
Tractor
HANDLE FUEL SAFELY-AVOID
FIRES

Wear close tting clothing. Stop the engine
and be sure PTO drive is stopped before mak-
ing adjustments, connections, or cleaning out
PTO driven equipment.
ALWAYS USE SAFETY LIGHTS
AND DEVICES
Use of hazard warning lights and turn signals
are recommended
when towing equipment on public roads un-
less prohibited by state
or local regulations.

installed.
Replace worn or broken parts. Replace dam-
age/missing decals.
Remove any buildup of grease or oil from the
Tractor.

making adjustments on electrical systems or
welding on Tractor
AVOID HIGH-PRESSURE FLUIDS
Escaping uid under pressure can penetrate
the skin causing serious injury. Keep hands
and body away from pinholes and nozzles,
which eject uids under high pressure. If
ANY uid is injected into the skin. Consult
your doctor immediately.
PREVENT BATTERY EXPLOSIONS

SAFETY PRECAUTIONS
PREVENT ACID BURNS
Sulfuric acid in battery electrolyte is poison-
ous. It is strong enough to burn skin, cause
holes
in clothing and cause blindness if found entry
into eyes.
For adequate safety always;
1.Fill batteries in a well-ventilated area.
2.Wear eye protection and acid proof hand
gloves
3.Avoid breathing direct fumes when electro-
lyte is added.
4.Do not add water to electrolyte as it may
splash off causing severe burns.
If you spill acid on yourself;
1.Flush your skin with water.
2.Flush your eyes with water for10~15min-
utes. Get medical attention immediately.
SERVICE TRACTOR SAFELY
Do not wear a necktie, scarf or loose cloth-
ing when you work near
moving parts. If these items were to get
caught, severe injury could result.
Remove rings and other jeweler to prevent
electrical shorts and entanglement in mov-
ing parts.

- 19
SAFETY PRECAUTIONS
WORK IN VENTILATED AREA
Do not start the Tractor in an enclosed build-
ing unless the doors &
windows are open for proper ventilation, as
tractor fumes can cause
sickness or death. If it is necessary to run an
engine in an enclosed area
remove the exhaust fumes by connecting ex-
haust pipe extension.
TRACTOR RUNAWAY
1. The tractor can start even if the trans-
mission is engaged position causing
Tractor to runaway and serious injury
to the people
standing nearby the tractor.
2. For additional safety keep the pull to
stop knob (fuel shut off control) in ful-
ly pulled out position.
Transmission in neutral position, Foot
brake engaged and PTO lever in disen-
gaged position while attending to Safe-
ty Starter
Switch or any other work on Tractor.
SAFETY STARTER SWITCH
1. Brake operated safety switch is pro-
vided on all Tractors which allow the
starting system to become operation-
al only when the Brake pedal is fully
pressed.
2. Do not By-pass this safety starter
switch or work on it. Only Authorized
Dealers are recommended to work on
safety starter switch.
3. On some models Safety Starter switch
is provided on transmission High-low
