Prime
WARNING
The fuel pump high-pressure fuel lines and fuel rail
contain very high-pressure fuel. Never loosen any
fittings while the engine is running. Personal injury
and property damage can result.
To prime the engine use the OEM installed priming
device. Typically, a priming pump is installed at or near
the pre-filter. See the OEM's instructions for the number
of strokes (hand primer) or the cycle time (electric priming
pump) needed to prime the low pressure system.
NOTE: It is not necessary to vent air from the high
pressure system before starting the engine.
NOTE: To prevent damage to the hand pump priming
seals, clean the fuel pump head and priming pump with
Quick Dry Spray Cleaner, Part Number 3824510, or
equivalent, and compressed air prior to priming the fuel
system.
Operate the engine and check for leaks.
Lubricating Oil and Filters
Drain
WARNING
Some state and federal agencies have determined
that used engine oil can be carcinogenic and cause
reproductive toxicity. Avoid inhalation of vapors,
ingestion, and prolonged contact with used engine
oil. If not reused, dispose of in accordance with local
environmental regulations.
WARNING
To reduce the possibility of personal injury, avoid
direct contact of hot oil with your skin.
Change the lubricating oil and filter(s) at the specified oil
change interval. See the Maintenance Schedule to find
the correct change interval for your application.
NOTE: For most engines, use a container that can hold at
least 20 liters [21 qt] of lubricating oil. Some engines can
be equipped with an increased capacity oil pan requiring a
container that will hold 28 liters [30 qt] of lubricating oil.
Operate the engine until the water temperature reaches
60°C [140°F].
Shut off the engine.
Remove the oil drain plug. Drain the oil immediately to be
sure all the oil and suspended contaminants are removed
from the engine.
