OPERATION
LUBRICATION
Lubricate the air suspension seat at locations shown
using IH 251H EP grease or equivalent NLGI #2 multi-
purpose lithium grease.
ENGINE OPERATING INSTRUCTIONS
The engine operator must assume responsibility of
engine care while engine is being operated.
There are
comparatively few rules which operator must observe to
get best service from a Cummins Diesel.
NEW AND REBUILT ENGINE BREAK-IN
Cummins engines are run-in on dynamometers
before being shipped from the factory and are ready to
be put to work in applications such as emergency fire
trucks.
In other applications, the engine can be put to work, but
the operator has an opportunity to establish conditions
for optimum service life during initial 100 hours or 3000
mi.
(4827 km) of service by:
1.
Operating as much as possible in half to
three-quarter throttle or load range.
2.
Avoiding operation for long periods at engine
idle speeds, or at maximum horsepower levels in excess
of five minutes.
3.
Developing the habit of watching engine
instruments closely during operation and letting up on
throttle if oil temperature reaches 250 deg.
F (121 deg.
C) or coolant temperature exceeds 190 deg.
F (88 deg.
C).
4.
Operating with a power requirement that allows
acceleration to governed speed when conditions require
more power.
5.
Checking oil level at each 300 mi.
(483 km) or
10 hours during the break-in period.
