For 5 minutes after engine start-up, allow the engine to
warm up without applying any load; this is to allow oil to
reach every engine part. If load should be applied to
the engine without this warm-up period, trouble such as
seizure, breakage or premature wear may develop.
1. Warm-up and transmission fluid at
low temperature range
Hydraulic oil serves as transmission fluid. In cold
weather, the oil may be cold with increased viscosity.
This can cause delayed oil circulation or abnormally
low hydraulic pressure for some time after engine start-
up. This in turn can result in trouble in the hydraulic
system.
To prevent the above, observe the following
instructions:
Warm up the engine at about 50% of rated rpm
according to the following table:
Ambient temperature
Warm-up time requirement
Higher than 0
℃
(32
℉
)
Approx. 5 minutes
0 to -10
℃
(32 to 14
℉
)
10 to 20 minutes
-10 to -20
℃
(14 to -4
℉
)
20 to 30 minutes
Below -20
℃
(-4
℉
)
More than 30 minutes
IMPORTANT :
• Do not operate the tractor under full load
condition until it is sufficiently warmed up.
JUMP STARTING
WARNING
To avoid personal injury or death:
• Battery gases can explode. Keep cigarettes,
sparks, and flames away from battery.
• If the tractor battery is frozen, do not jump start
engine.
• Do not connect the other end of the negative (-)
jumper cable to the negative (-) terminal of the
tractor battery.
• When taking out the dead battery, putting in the
battery or fixing the battery, do not allow the
positive (+) terminal of the battery to touch
other parts.
When jump starting the engine, follow the instructions
below to safely start the engine.
1. Bring the helper vehicle with a battery of the same
voltage as the disabled tractor within easy cable
reach.
IMPORTANT :
• The vehicles must not touch.
2. Engage the parking brakes of both vehicles and put
the shift levers in neutral. Shut both engines off.
3. Wear eye protection and rubber gloves.
4. Attach the red clamp to the positive (red, (+) or
positive) terminal of the dead battery and clamp the
other end of the same cable to the positive (red, (+)
or positive) terminal of the helper battery.
5. Clamp the other cable to the negative (black, (-) or
negative) terminal of the helper battery.
6. Clamp the other end to the engine block or frame of
the disabled tractor as far from the dead battery as
possible.
7. Start the helper vehicle and let its engine run for a
few moments. Start the disabled tractor.
8. Disconnect the jumper cables in the exact reverse
order of attachment (steps 6, 5 and 4).
Connect cables in numerical order.
Disconnect in reverse order after use.
(1) Dead battery
(2) Jumper cables
(3) Helper battery
IMPORTANT :
• This tractor has a 12 volt negative (-) ground
starting system.
• Use only the same voltage for jump starting.
• Use of a higher voltage source on tractor's
electrical system could result in severe
damage to tractor's electrical system.
Use only matching voltage source when
“Jump starting” a low or dead battery
condition.
• Do not operate the tractor with the battery
cable disconnected from the battery.
• Do not operate the tractor without the
battery mounted.
• Do not operate the tractor with the battery
dead. Charge the battery fully before
operating the tractor.
Otherwise, the tractor might malfunction.
