CAUTION
The following instructions should only
be used in emergency situations when
the fuel tank has run dry. Failure to fol-
low the starting instructions below may
damage the starter motor.
1. Loosen the fuel primer pump knob by
rotating it counter-clockwise.
2. If equipped with a return fuel
blending valve, turn the valve to the
PRIME (closed) position.
3. Operate the priming pump by moving
the knob in and out for 150 seconds.
During this time the pumping
resistance will increase, but the full
time is required to fully prime the fuel
system.
CAUTION
Operate priming pump at a maxi-
mum rate of 30 strokes per mi-
nute to prevent damage to pump.
4. Check for leakage at the fuel
filtercap. Tighten if necessary.
WARNING
Check the fuel filter for signs of
leakage. DO NOT smoke or al-
low an open flame in close prox-
imity. Failure to do so could ignite
a fire or cause an explosion
which could result in serious in-
jury to you and/or bystanders.
Failure to comply may result in
death, personal injury, equipment
or property damage.
5. Start the engine and allow it to idle
for several minutes. Note that it could
take up to 15 seconds of cranking for
the engine to start. If the starter is
engaged for longer than 20 seconds
without starting, additional priming
pump actuation may be necessary.
CAUTION
If the engine is cranked exces-
sively Starter Protection will be
triggered and starter engage-
ment will be restricted for 10 mi-
nutes.
NOTE
Allowing the engine to idle for
several minutes with the fuel
blending valve in the prime posti-
tion assists in purging air from
the fuel system.
6. Check the system for leakage while
idling. Then turn the engine off and
check the system again for leakage.
7. If the engine does not start within this
time, repeat steps two and three until
the engine starts. If the engine still
does not start, allow the starter to
cool down for at least 5 minutes
before repeating the procedure.
