WARMING UP
Hydraulic oil serves as transmis-
sion fluid. In cold weather, the oil
may be cold with increased viscos-
ity. This can cause delayed oil cir-
culation or abnormally low hydrau-
lic pressure for some time after en-
gine start-up. This in turn can re-
sult in trouble in the hydraulic sys-
tem. To prevent the above, ob-
serve the following instructions:
Warm up the engine at about 50 %
of rated rpm according to the table
below:
WARM-UP AND TRANSMISSION OIL IN
THE LOW TEMPERATURE RANGE
After starting your tractor's engine al-
low five minute warm up before ap-
plying any load to the tractor. This
will allow time for oil to reach ev-
ery part of the engine. If a load is ap-
plied to the tractor before it has time
to warm up, serious damage, such
as can occur premature wear, break-
age, or seizure.
CAUTION
During warm up of the engine,
be sure that the parking brake
is set.
During warm up of the engine,
make sure that all shift levers
are in the neutral position.
IMPORTANT
Do not operate the tractor un-
der full load condition until it
is sufciently warmed up.
