nozzles and/or injection pump to avoid damage.

two
open-end wrenches, loosen two fuel line connections at injection
nozzles.
2. Crank engine over with starter motor for 15 second (but do not start engine)
until fuel free from bubbles flows out of loosened connection. Retighten
connection to specifications.
3. Repeat procedure for remaining injection nozzles (if necessary) until all air has
been removed from fuel system.
If engine still will not start, see your authorized servicing dealer or engine distributor.
Do Not Modify Fuel System
IMPORTANT: Modification or alteration of the injection pump, the injection pump
timing, or the fuel injectors in ways not recommended by the manufacturer will
terminate the warranty obligation to the purchaser.
In addition, tampering with fuel system which alters emission-related equipment on
engines may result in fines or other penalties, per EPA regulations or other local
emission laws.
Do not attempt to service injection pump or fuel injectors yourself. Special training and
special tools are required. (See your authorized servicing dealer).
