(ROPS) Roll Over Protective Structures

►

►►

► ROLLOVER PROTECTIVE STRUCTURES (ROPS)

TYM Tractors are equipped with a frame for the protection of operators.
In the case of cab tractors the frame is incorporated 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 bases and bolts or other fasteners.

DANGER

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.

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

Take care when lowering the upper section of the ROPS frame and take extreme care while

driving the tractor 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 circumstances only and must not be lowered for general use.

Use of the tractor with the ROPS lowered can cause fatal injuries.

As the ROPS frame or cab together with the seat belt was designed to meet certain standards,
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 certification 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.

►

►►

► 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 provide the original protection. After an accident, check for damages
to the 1.ROPS.2.Seat 3.seat belt & seat mountings. Before you operate a Tractor, replace all damaged

parts.

►

►►

► 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 backwards. Always pull from the Tractor drawbar. Be careful
when driving through door opening or under low overhead objects. Make sure
there is sufficient overhead clearance for the ROPS fatal injuries

If the ROPS is removed or replaced, make certain that the proper hardware is
used to replace the ROPS and the recommended torque values are applied to
the attaching bolts

Always wear your seat belt if the tractor is equipped with ROPS

■ From the table above we learn about the safety features of the PTO. When the monitor on the dash

panel is blinking it indicates to the operator that the PTO is in the on position but temporarily not
rotating either because the clutch pedal is pressed or the implement is lifted off the ground or both.
The PTO will start rotating instantaneously when either the clutch pedal is released and/or the
implement is lowered to the ground.

■■■■

The operator must use this blinking signal to clear the area around the tractor off

The operator must use this blinking signal to clear the area around the tractor off

bystanders/onlookers as the rotating blades of certain implements can accidentally cause injuries to
the persons standing near the tractor.

■

■■

■ The stopping of the PTO when the implement is lifted off the ground with the position control

prevents the damage to the implement or the PTO shaft.

1.When the PTO control switch is in manual position the PTO does
not stop rotating even if the clutch pedal is pressed. If working on
hard soils,pavements with a rotary implement the PTO ON/OFF
switch must be put to the OFF position to stop the PTO from rotating ,
If this is not done the rotating blades of the implement will push on
the hard ground below and in turn push the tractor toward causing
accident which can lead to serious injuries or death.

2. Extra precaution must be taken to clear the area of bystanders/onlookers when using PTO driven

implements. The rotating blades of the implements can cause serious injuries on contact. The
warning that is indicated by the blinking PTO monitor is to make the operator aware that the
PTO is in on position and will instantly start rotating if the clutch pedal is released or implement
is lowered or both.

3.In no case the specified rotating speeds indicated by the implement manufacturer be crossed
as the same can lead to serious damage to the tractor/equipment and can lead to serious injuries
to persons around.

Only engage the starter for a period of not more than 10 seconds.

If Engine does not start, rest the starter for about 20 seconds and try again for a
maximum of 10 seconds.If the engine does not start after repeated attempts,
refer to the fault tracing guide.

Especially in cold weather, always allow the tractor to idle for a while to warm
up & build up sufficient oil pressure to ensure normal operating temperature for
longer engine life.

Important

►

►►

► STOPPING THE ENGINE

-After light work let the engine idle for a while and turn the key off.

After long or heavy work allow the engine to idle for 5- 10 minutes and turn the
key off.

Important

Important

►

►►

► WARMING UP

When starting the engine allow it to warm up to operating temperature by allowing it to idle 5-10
minutes to ensure full lubrication and operating temperature.
Failure to do so can shorten engine life substantially.

►

►►

► WARMING UP IN COLD WEATHER

Cold weather will change the viscosity of the oil, resulting in a reduced oil pumping capacity, which
can cause damage to the engine if it is not warmed up correctly.It also causes problems with the
hydraulic system and the synchromesh in the transmission.

Correct times for warming up are:

Temperature Time for warming up

Above 50°F

5~10 min.

50°F~ 32°F

10~20 min.

32°F~14°F

20~30 min.

14°F~-4°F

30~40 min.

Below –4°F

Over 40 min.

Important

Ensure the handbrake (Foot brake) is on during the warming period.

Failure to warm up correctly can result in problems.

When the engine is warm push down the clutch and engage the main and auxiliary gear levers to the
required position.
Push down on the brake pedals and release the handbrake.
Increase the engine revolutions and let out the clutch smoothly.

Only change gears with main gear lever while moving and ensure that this is done with fully use of
the clutch.

►

►►

► STORING ENGINE IN OPERABLE CONDITION FOR 3 MONTHS OR MORE

When the engine is not operated during storage of three months or more, internal engine parts can rust
and lose oil film. As a result, the engine can seize when it is started after storage.
To prevent such a rust, the engine must be operated periodically during storage.

Do not ”ride” the clutch to control speed, use a lower gear.
Do not travel with your foot on the clutch pedal.

Caution

Always connect the brake pedals when traveling on the road.
Never tow anything except with the drawbar.
Do not tow loads which are too large for the tractor’s capacity to brake effectively
especially in hilly terrain.
Take special care when towing large or wide implements.
Do not carry passengers.
At all times observe local legislation and road rules.

Danger

►

►►

► TIGHT TURNS IN THE FIELD

Disconnect the latch connecting left and right brake pedals
to allow the use of individual pedals.
To make a tight turn use both the steering wheel and the
brake pedal at the same time.

For a left turns use the left pedal and a right turn the right pedal.

Perform tight turns only at a slow safe speed.
Doing so at a high speed can cause rollovers and very serious injury or death.

Caution

►

►►

► NORMAL BRAKING AND PARKING

Let the engine come back to idle and at the same time push in the
clutch and brake simultaneously.
When the tractor has come to a halt, lower any implement to the
ground, and put the main gear in neutral.
Apply the park brake, stop the engine, and remove the key.

Always apply the park brake when parking.
Failure to do so can cause accidents and damage.
As an extra precaution when parking on a slope, chock the rear wheels.

Caution

Illustration

►

►►

► DRIVING DOWNHILL

Use the engine’s ability to brake when traveling downhill.
Never rely on the brakes only and never travel downhill with the gears in neutral.

When operating in hilly terrain the risk of the rollover is increased substantially,
please drive with extra care.

When towing trailers in hilly terrain ensure that they are equipped with brakes, use a
lower gear to get maximum engine braking and do not change gears on a down hill
run

►

►►

► OPERATION OF THE DIFF LOCK

While the diff lock is a very useful feature, care should be taken in its use as misuse can lead to

►

►►

► UPHILL STARTS ON A STEEP SLOPE

With the pedals connected together push down on the brake
pedals and push down the clutch.
Set all gear levers to low and the throttle to medium engine speed.
Release the clutch and as it engages release the brake pedals.
Adjust the throttle to the required speed.

Warning

dangerous situations.

The diff lock would only be used in situations where traction is lost on one of the rear wheels.

Use low engine revolutions when using the diff lock.
If the diff lock does not release after removing the foot from the pedal use the left

and right brake pedals in turn to release it.
Do not try to engage or use the diff lock on tight turns as serious damage can result.

►

►►

► CHECK DURING DRIVING

Constantly monitor the warning lights on the dash and if any
comes on stop the tractor to determine the cause.
If the oil pressure light comes on check the oil level first of all.
If the oil level is OK ask a qualified dealer to check the
reason for the light coming on.
If the alternator warning light comes on check all
connections and ensure that the fan belt is not broken.
If all connections and the fan belt are intact consult your
dealer to determine the cause of the problem.

Warning

►

►►

► FUEL GAUGE.

To avoid excessive condensation in the fuel tank refill at the end of each
day’s work and ensure during the day that it does not drop to a low level
where the fuel system will require bleeding to expel air in the system after
refilling the tank.

►

►►

► ENGINE COOLING WATER.

If the gauge indicates that the engine is running hot, stop the tractor and
check the coolant in the radiator.

►

►►

►

►►

► CHECKING HOSES AND LINES

The fuel lines, radiator hoses, hydraulic and rubber hoses are consumables, which deteriorate
by age and use.
Check them regularly and replace if faulty.

Damaged fuel lines leak and cause fires.
Damaged radiator hoses can cause hot water burns and in severe cases seize the

engine.

Caution

►

►►

► CHECKING THE WIRING HARNESS AND FUSES

Loose wires make inferior connections and damaged wires can cause short circuits, fires burnt wiring
or reduce efficiency of components.
Replace or repair any faulty wiring or insulation.
If a fuse burns out again after it has been replaced, do not replace it with wire or a high capacity fuse,
find the cause and rectify it or get an auto electrician to do so.
Where insulation is chafed or peeled off, recover the area with a good quality insulation tape. Where
wiring comes out of it’s fitting replace it correctly with the standard fitting.

important

Incorrect wiring or fuses can cause fires to both the tractor and surrounding area so

get the dealer to check it annually.
Likewise fuel pipes and wiring age with use.
Ask your dealer to check it at least once every 2 years and replace as required

►

►►

► REPLACING FUSES

The circuit has 8 blade type fuses in its wiring circuit
(See diagram on page 83 and 84)
When a fuse has blown replace it with one of the same value.
Using a large capacity fuse or wire burn out the wiring system.
Use fuse tongs to replace fuses

►

►►

► MAIN FUSES

The wiring harness is equipped with 3 main fuses who’s
function is to preserve the wiring.
However when a main fuse blows the entire circuit is dead.
Always check the reason & rectify before replacing the
fuse of the same value.
To indicate that the fuse is blown it will be discolored.

important

Always check the reason for a blown fuse otherwise the new fuse is also likely to
blow.
NEVER EVER USE WIRE in place of correct grade fuse.

►

►►

► SERVICE PRIOR TO DAILY AND SHORT TERMS STORAGE.

FUEL SAVING TIPS

To save fuel & oil in your tractor, following things should always be kept in mind.

A) Air cleaning system

1) Clean the air cleaner regularly so that dust does not settle down.

2) For every 50 hours & everyday in sandy/dusty conditions.

(a) Clean the air cleaner filter element with compressed air.
(b) If the rubber ring is cut or expanded then change it with an appropriate one.

Fix the rubber at the proper location & check for leakages if any.

(c) If air is leaking through the hose connection, check & rectify other leakages, too.

Note: If air cleaning system is not properly maintained, it will lead to early wear of piston rings

& sleeves. This will lead to problems like loss of engine power,, excessive oil consumption
fuel consumption.

B) Engine

1) put the engine oil on load after the engine is heated & the water temperature gauge indicates
the needle to be in the green zone.

2) If excessive black smoke is visible, then the paper element of air cleaner, Fuel injection

Pump or nozzles should be checked.

Pump or nozzles should be checked.

3) Do not run the engine without load for more than 2 minutes. It is better to stop the engine

rather than run it idle. This will help in saving of fuel.

C) Clutch & Brakes.

1) Do not reduce the power of the power of the engine by depressing the clutch halfway. Instead
use low gear.

2) If the Tractor has to be stopped for a long period, it is advisable to bring the transmission in
neutral position & release the clutch pedal.

3) Do not over ride the clutch & brake pedals.

4) While coming down from a slope, reduce the engine throttle & use low gear. Do not depend

only on the brakes for stoppage.

D) Fuel system

1) Always use filtered diesel for the fuel system

2) At the end of the day’s working, it is preferable to fill the diesel tank so that it may prevent

condensation.

3) Change the filter, if the system gets choked. Do not change both the filters at the same time.

If the above directives are not adhered to, the fuel injection pump & injection nozzle will lose
its life early. Also, it will lead to excessive black smoke & excessive diesel consumption.

E) Lubrication system

1) Always use recommended grade of oil.

2) Everyday before starting the engine, check the oil level with a dipstick & refill between the
minimum & maximum level.

3) Charge the engine oil, Replace filter & “O” ring, as & when required.

F) Cooling system

1) Check the fan belt tension regularly. Adjust, If required.

2) Check the coolant level in the radiator fins always clean.

3)Replace the radiator cap with a genuine cap only, if required.

4) Do not remove the thermostat but replace with a new one, if required.

5) Do not change the radiator water often.

Note:

1) Always stop any fuel or oil leakages.

2) Carry out the regular maintenance failure to do so might increase the fuel consumption by 25%.

3) Carry out the torque of cylinder head bolt & adjustment of valve clearance regularly. Consult
your dealer for this.

4) Check the tire pressure & inflate, as recommended.

5) Always buy genuine spares from the authorized Dealer/Distributor.
