Warming Up; Warm-Up And Transmission Oil In The Low Temperature Range; Jump Starting - Kubota BX25DLB Operator's Manual

26 OPERATING THE ENGINE

WARMING UP

To avoid personal injury:
A Be sure to set the parking brake during warm-
up.
A Be sure to set all shift levers to "NEUTRAL"
positions and to place PTO lever in "OFF"
position during warm-up.
For 5 minutes after engine start-up, allow 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.
BWarm-up and Transmission Oil in the 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 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 above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:
Ambient temperature
Above 0 (32 )
-10 to 0 (14 to 32 )
-20 to -10 (-4 to 14 )
Below -20 (-4 )
A Do not operate the tractor under full load condition until
it is sufficiently warmed up.

JUMP STARTING

To avoid personal injury:
A Battery gases can explode. Keep cigarettes,
sparks, and flames away from battery.
A If tractor battery is frozen, do not jump start
engine.
A Do not connect other end of negative (-) jumper
cable to negative (-) terminal of tractor battery.
A When carrying on the following steps 4 and 11,
do not allow the positive (+) terminal of the
battery to touch other parts.
Warm-up time requirement
At least 5 minutes
5 to 10 minutes
10 to 15 minutes
More than 15 minutes
When jump starting engine, follow the instructions below
to safely start the engine.
1. Bring helper vehicle with a battery of the same voltage
as disabled tractor within easy cable reach. "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. Put on safety goggles and rubber gloves.
4. Take the dead battery out and put it on the step.
5. Ensure the vent caps are securely in place. (if
equipped)
6. 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.
7. Clamp the other cable to the negative (black, (-) or
neg.) terminal of the helper battery.
8. Clamp the other end to the engine block or frame of
the disabled tractor as far from the dead battery as
possible.
9. Start the helper vehicle and let its engine run for a few
moments. Start the disabled tractor.
10. Disconnect the jumper cables in the exact reverse
order of attachment. (Steps 8, 7 and 6).
11. Put the battery back and fix it.
(1) Dead battery
(2) Jumper cables
(3) Engine block or frame
(4) Helper battery
A This machine has a 12volt negative (-) ground starting
system.
A Use only same voltage for jump starting.
A Use of a higher voltage source on tractors electrical
system could result in severe damage to tractors
electrical system.
Use only matching voltage source when "Jump
starting" a low or dead battery condition.
