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:
A Do not operate the tractor under full load condition until
it is sufficiently warmed up.
1. After slowing the engine to idle, turn the
key to "OFF".
2. Remove the key.
1. After slowing the engine to idle, wait 3
to 5 minutes for turbo to slow down
then turn the key to "OFF".
2. Remove the key.
Ambient temperature Warm-up time requirement
Above 0 C (32 F) At least 5 minutes
0 to -10 C (32 to 14 F) 5 to 10 minutes
-10 to -20 C (14 to -4 F) 10 to 15 minutes
Below -20 C (-4 F) More than 15 minutes
