4TNV98 & 4TNE98 Diesel Engine Section 2. Periodic Maintenance 38
CAUTION
New Engine Break-in:
• On the initial engine start-up, allow the engine
to idle for approximately 15 minutes while you
check for proper engine oil pressure, diesel
fuel leaks, engine oil leaks, coolant leaks, and
for proper operation of the indicators and/or
gauges.
• During the first hour of operation, vary the
engine speed and the load on the engine.
Short periods of maximum engine speed and
load are desirable. Avoid prolonged operation
at minimum or maximum engine speeds and
loads for the next four to five hours.
• During the break-in period, carefully observe
the engine oil pressure and engine
temperature.
• During the break-in period, check the engine
oil and coolant levels frequently.
CAUTION
NEVER engage the starter motor while the
engine is running. This may damage the starter
motor pinion and/or ring gear.
CAUTION
It is important to perform daily checks.
Periodic maintenance prevents unexpected
downtime, reduces the number of accidents due
to poor machine performance and helps extend
the life of the engine.
CAUTION
ALWAYS be environmentally responsible.
Follow the guidelines of the EPA or other
governmental agencies for the proper disposal
of hazardous materials such as engine oil,
diesel fuel and engine coolant. Consult the local
authorities or reclamation facility.
NEVER dispose of hazardous materials
irresponsibly by dumping them into a sewer, on
the ground, or into ground water or waterways.
Failure to follow these procedures may
seriously harm the environment.
CAUTION
Protect the air cleaner, turbocharger (if
equipped) and electric components from
damage when you use steam or high-pressure
water to clean the engine.
CAUTION
NEVER overfill the engine with engine oil.
ALWAYS keep the oil level between the upper
and lower lines on the oil cap/dipstick.
