• Be sure to set all shift levers to the neutral
positions and to place the PTO-clutch-lever
in the off position during warm-up of the
engine.
For 5 minutes after the engine start-up, warm up the
engine without applying any load. The purpose is to
allow oil to reach every engine-part.
If the load should be applied to the engine without
preceding warm-up period, trouble such as seizure,
breakage, or premature wear may develop.
1. Warm-up of the engine and
transmission oil in the low
temperature range
IMPORTANT :
• Do not operate the tractor under full load
condition until it is sufficiently warmed up.
Hydraulic oil serves as transmission fluid. In cold
weather, the hydraulic oil may be cold with increased
viscosity. The hydraulic oil with increased viscosity
can cause delayed oil circulation or abnormally low
hydraulic pressure for some time after engine start-
up. Delayed oil circulation or abnormally low hydraulic
pressure in turn can result in premature wear in the
hydraulic system or malfunctions such as resistance
in the speed-control-pedal and difficulty engaging the
range-gear-shift-lever. To prevent the premature wear
in the hydraulic system or malfunctions of controls,
check the following instructions.
Warm up the engine at about 50% of rated rpm
according to the following table.
Ambient temperature Warm-up time requirement
Above 0 ℃ At least 5 minutes
-10 ℃ to 0 ℃ 5 minutes to 10 minutes
-20 ℃ to -10 ℃ 10 minutes to 15 minutes
Below -20 ℃ More than 15 minutes
JUMP STARTING THE ENGINE
Follow the instructions of jump starting of the engine to
safely start the engine.
WARNING
To avoid serious injury or death:
• Battery gases can explode. Keep cigarettes,
sparks, and flames away from the battery.
• If the tractor battery is frozen, do not jump start
the engine.
• Do not connect other end of negative (-) jumper
cable to negative (-) terminal of the tractor
battery.
• Do not allow the positive (+) terminal of the
battery to touch other parts.
• To prevent short circuit, before connecting
jumper cables, make sure to remove the metal-
battery-holder.
(1) Battery holder
IMPORTANT :
• The tractor equips a 12 volt negative (-) ground
starting system.
• Use only the same voltage for jump starting.
• Use of a higher voltage source on the electrical
system of tractor could result in severe damage
to the electrical system of tractor.
Use only matching voltage source when jump
starting in a low battery condition or a dead
battery condition.
• Since the metal-battery-holder can crack, do not
tighten it too much.
Connect cables in numerical order.
Disconnect in reverse order after use.
(1) Dead battery
(2) Jumper cables
(3) Right bolt
(4) Helper battery
