OPERATING THE ENGINE 14
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 the "NEUTRAL"
positions and to place PTO clutch lever in
"OFF" position during warm-up.
For five 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.
B
Warm-up Transmission Oil at Low
Ambient Temperatures
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 table below:
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.
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. Ensure the vent caps are securely in place. (if
equipped)
5. Cover vent holes with damp rags. Do not allow the rag
to touch the battery terminals.
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. Remove and discard the damp rags.
