Changing Oil And Oil Filter Before First 250 Hours
4. During the first 20 hours, avoid prolonged periods of
engine idling or sustained maximum load operation. If
engine will idle longer than 5 minutes, stop engine.
5. Before the first 250 hours (maximum), change engine
oil and replace engine oil filter. (See CHANGING
ENGINE OIL AND REPLACING OIL FILTER in
Lubrication and Maintenance/250 Hour/6 Month
Section.) Fill crankcase with the normal seasonal
viscosity grade oil. (See DIESEL ENGINE OIL, in
Fuels, Lubricants, and Coolant Section.)
NOTE: Some increase in oil consumption may be
expected when low viscosity oils are used. Check
oil levels more frequently.
If air temperature is below -10
°
C (14
°
F), use an
engine block heater.

A—Coolant Temperature Gauge
6. Watch coolant temperature gauge (A) closely. If
coolant temperature rises above 112°C (234°F), reduce
load on engine. Unless temperature drops quickly, stop
the engine and determine the cause before resuming
operation.
NOTE: When the coolant temperature gauge reads
approximately 115
°
C (239
°
F), the engine will
shutdown automatically, if equipped with safety
controls.
7. Check poly-vee belt for proper alignment and seating
in pulley grooves.
