Warming Up; Warm-Up Transmission Oil At Low Ambient Temperatures; Jump Starting - Kubota B2301-1 Operator's Manual

14 OPERATING THE ENGINE

WARMING UP

To avoid personal injury or death:
A Be sure to set the parking brake during warm-
up.
A 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.
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.
BWarm-up Transmission Oil at Low
Ambient Temperatures
Hydraulic oil serves as transmission fluid. In cold weather,
the oil will be cold, which will increase oil 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 table below:
Ambient temperature
Above 0 C (32 F)
0 to -10 C (32 to 14 F)
-10 to -20 C (14 to -4 F)
Below -20 C (-4 F)
A Do not operate the tractor under full load condition until
it is sufficiently warmed up.
Warm-up time requirement
At least 5 minutes
5 to 10 minutes
10 to 15 minutes
More than 15 minutes

JUMP STARTING

To avoid personal injury or death:
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 the other end of the negative
(-) jumper cable to the negative (-) terminal of
the tractor battery.
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 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. Wear 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 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)
(1) Dead battery
(2) Jumper cables
(3) Helper battery
A This machine has a 12volt negative (-) ground starting
system.
