7a. To start the engine using the electric
starter:
Insert the ignition key into the igni-
tion. While turning the key to Start (S
position, max 5 seconds) very slowly
move the choke lever from cold to run
position.
Note: To prolong starter life, use
short starting cycles (5 seconds maxi-
mum). Then wait one minute before
attempting to start again.
To start the engine manually: 5b.
To re-start a warm engine, move the
Choke to halfway closed. Insert the
ignition key into the Ignition and turn
the Key to Run (I position). Grasp
the starter handle, and pull slowly
until resistance is felt. While holding
the handle, allow the starter rope to
rewind slowly. Then, pull the starter
handle with a rapid, full arm stroke.
Once again while holding the handle,
allow the rope to rewind slowly. Re-
peat as necessary, until the engine
starts.
Allow the Engine to run for sev-6.
eral seconds. Then, if the Choke is
closed, open it (move to the run posi-
tion).
Note: Moving the Choke too fast could kill
the engine.
IMPORTANT: Allow the engine to run 7.
at no load for ve minutes after each
start-up so that the engine can stabi-
lize.
Close the pilot valve after the engine 8.
has started, by laying the pin down.
This allows the compressor to build
up pressure.
When the Gas Engine (A4) is started 9.
and running, the Air Pump (A2) starts
compressing air into the Air Tank
(A18) for storage.
When maximum tank pressure is 10.
reached, the compressor automati-
cally disengages, and the engine
RPM drops down to idle speed. The
engine remains at idle until Air Tank
pressure falls to a preset level. The
Gas Engine will then accelerate and
air pressure once again begins to
build up in the Air Tank.
To turn off the engine, turn the key off 11.
(0 position). Close the fuel valve.
Drain the moisture from the tank 12.
