engine-part. If the load should be applied to the engine
without the warm-up period of 5 minutes, 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 oil may be cold with increased viscosity.
The 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 trouble in the hydraulic system. To prevent the
trouble in the hydraulic system, check the following
instructions.
Warm up the engine at about 50% of rated rpm
according to the following table.

JUMP STARTING THE ENGINE
When jump starting the engine, follow the instructions
in this section to safely start the engine.
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
the 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.
IMPORTANT :
• This machine is equipped with 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 the tractor could result in severe
damage to the electrical system of the tractor.
Use only matching voltage source when jump
starting in a low battery condition or a 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 enough before
operating the tractor.
Otherwise the tractor might malfunction.
Connect cables in numerical order.
Disconnect in reverse order after use.
(1) Dead battery
(2) Jumper cables (3) Helper battery
1. Bring the helper vehicle with a battery of the same
voltage as the disabled tractor within easy cable
reach.
IMPORTANT :
• The helper vehicle must not touch the
disabled tractor.
2. Engage the parking brakes of both vehicles and put
the shift levers in the “NEUTRAL” position. Shut
both engines off.
3. Wear an eye protection and rubber gloves.
4. Attach the red clamp to the positive (red, (+) or
pos.) terminal of the dead battery, and clamp the
other end of the same cable to the positive (red, (+)
or pos.) terminal of the helper battery.
5. Clamp the other cable to the negative (black, (-) or
neg.) terminal of the helper battery.
6. Clamp the other end of the cable, which is clamped
to the negative terminal of the helper battery, 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.
