OPERATION
WARNING
!!!!!
After operating the tractor or en-
gine, never touch the muffler or
the heat shield until it has suffi-
cient time to cool.
To avoid the damage to the turbo
charger of this engine:
Do not accelerate quickly right

mended before getting into the
work and also before the engine
stop.
!!!!!
CAUTION
WARMING UP
After starting your tractors engine al-
low a five minute warm up before ap-
plying any load to the tractor. This will
allow time for oil to reach every part of
the engine. If a load is applied to the
tractor before it has time to warm up
then serious damage can occur like,
premature wear, breakage, or seizure.
To avoid personal injury:
During warm up of the engine be
sure that the parking brake is set.
!!!!!
CAUTION
Remove the key whenever you
leave the tractor. It prevents un-
authorized operators from start-
ing the tractor.
IMPORTANT
Hydraulic oil serves as transmission
fluid. In cold weather, the oil may be
cold with increased viscosity. This can
cause delayed oil circulation or abnor-
mally 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:
