Factory Direct Tractors
Running-in
3. Running-in
3-1
How the tractor is handled in the first 100 hours of
its working life has a big impact on how long it lasts
and its performance during its ‘life’. In order to get
the best out of your tractor and prolong its service
life, it is essential to follow the procedure outlined
below for a new tractor (new or overhauled engine).
The run-in period is the first 100 hours.
3.1 Engine run-in without load
Caution:
If the engine will not start, do not grind it over with
the key for more than 15 seconds at a time or the
starter motor could be damaged.
1.
Please read Safety Precautions and Safety
First in this Operation Manual before carefully
starting the engine.
To start the engine:
Before starting, know how to stop the engine, see
3.1. After carrying out the daily safety and service
checks, sit firmly in the seat. Adjust the seat to
a position in which you can fully operate all the
tractor controls and secure your seat belt. Ensure
the gear levers are in neutral position and the
PTO is disengaged. Move the hand throttle to the
medium position and push the clutch pedal firmly
to engage the safety switch. Ensure the fuel cut off
button is pushed right in and turn the ignition key
clockwise or right to the normal start position. The
tractor will start. Release the key and it will return
to the ‘ignition on’ position.
2. After starting, let the engine run at medium or
low speed, until the engine temperature reaches
50
o
C. Ensure the oil pressure gauge is indicating
normal. Avoid running the engine at high speeds
right after starting. While the engine is warming
up, check for any water, oil or air leakage and
that all instruments and indicators are working
normally.
3. Once warmed to operating temperature, run the
engine for 5 minute at maximum speed, keeping
an eye on the engine’s instruments to monitor
its working status. Then vary the engine rpm
cycling between medium to low speed. Run the
engine without load for a minimum of 20 to 30
minutes.
3.1 Stopping the engine
1.
Drive the tractor to a safe flat location.
2.
Disengage the PTO, gear and range levers and
apply the park brake.
3.
Lower the implement / loader to the ground, and
close the throttle to reduce engine speed.
4. Turn the ignition off.
5.
Pull the red fuel cut off button and hold it out till
the engine stops
6.
Push the button back in, remove the ignition key
and release your seat belt.
3.2 Tractor –No Load
1. Drive the tractor into a safe open ‘test’ area
with enough room to carry out the following
manoeuvres.
2. At varying slow to medium speeds, run the
tractor in every forward and reverse gear for half
an hour respectively. Run third and forth gear in
medium or low range. Use the steering from lock
to lock without holding on full lock. Manoeuvre
at medium and low speeds, applying LH brake
and RH brake in sync with the steering. With the
brakes interlocked, try emergency braking when
the tractor is running in gears 11 and 12 with
limited throttle. Engage the front wheel drive if
the tractor is a four-wheel drive model. Never
operate in four-wheel drive on hard surfaces.
While running in the transmission system, the
P.T.O. should be “disengaged”.
3. Engage the P.T.O., and operate the hydraulic
linkage system repeatedly to ensure all the
linkage joints are working smoothly together.
