OPERATING PROCEDURES (Continued)
The following step restores electrical stop capability to the control panel.
m. After engine is running, lower the manual start control (9) fully by alternately turning the lower and upper manual
start control knobs (8 and 10).
Serious personal injury could result from contact with rotating parts such as the engine or
starter coupling components. Keep body well clear of coupling while rotating. Do not allow
loose clothing near engine where it may be caught on rotating parts. Handle coupling guard
by sides when raising and keep fingers well clear of coupling.
Equipment damage may occur if the fuel transfer pump is allowed to run dry. When the fuel
transfer pump primes and moves pumpage, the outlet hose will expand. If the hose remains
flat, the fuel transfer pump has not primed and is running dry.
Verify that pump outlet hose pressurizes (hose expands). If hose has not pressurized after two minutes of operation, shut
down system and determine why pump has not primed.
Serious eye and skin injury could occur from venting of fuel when filter vessel manual vent
valve is open. Wear suitable protective clothing and eye protection.
At the liquid fuel filter-separator, depress and latch open the manual vent valve.
The fuel transfer pump may be damaged if allowed to run dry. Any air in the system which
reaches the fuel transfer pump will cause the pump to run dry. The fuel transfer pump will
pump air and regain suction if the air in the pump can be removed within a few minutes.
However, a large volume of air may cause the pump to run dry too long and seize. The large
volume of air initially in the filter vessel must be vented completely by filling the liquid fuel
filter-separator as slowly as possible while venting to allow all the air to escape.
Crack open the liquid fuel filter-separator inlet valve. Allow fuel to slowly fill filter vessel, forcing air out the manual
10. Close the manual vent valve at first appearance of fuel.
11. Open the liquid fuel filter-separator inlet and outlet valves fully. Allow fuel to recirculate 15 - 20 minutes.
