Turn decompression lever (3) clockwise to 12 o’clock position (position B).
Engage crank handle (4) in gear housing (5).
With both hands, turn crank handle (4) clockwise with increasing speed.
When decompression lever (3) reaches C position, the highest possible speed must be ob-
tained. Engine will start and go to maximum operating speed. Extra fuel device button (2)
will return to normal position by itself.
Adjust throttle control hand lever (1) to desired speed.
If engine does not start on initial attempt, allow engine rotation to
stop completely before engaging crank handle.
b. Bonding and Grounding Procedures
DEATH or serious injury may result if proper bonding and grounding
procedures are not followed prior to operating the equipment.
NOTE
Bonding is the process that equalizes the charge on two unlike objects such
as an aircraft and a refueling nozzle. It is done in order to prevent arcing,
in the presence of flammable vapors, as the two objects are joined.
(1) Extend the grounding cable (1) from the nozzle so it can be inserted into the vehicle/aircraft
receptacle (if present). Otherwise attach the grounding clip to a bare metal surface of the
receiving vehicle/aircraft. Bond before the dust cap or gas tank cap is removed to prevent
a spark occurring when fuel vapor is present. For the same reason, do not disconnect the
bond until refueling is complete and the gas tank cap and nozzle dust cap are replaced.

Immediate shutdown of the engine without a 5-minute idle time may
cause damage to the engine. Do so only when made necessary by
emergency conditions.
Slowly move throttle control hand lever toward STOP position to idle speed. Allow engine
to idle for 5 minutes to allow engine operating temperature to stabilize.
Drain water from water/separator before venting air from unit. Leave vent valve open during
shutdown.
Move throttle control hand lever to extreme right STOP position.
