OPERATION
STOPPING THE ENGINE
• Disconnect all electrical loads and let engine run at
no-load for about five minutes to stablize internal tom-
peratures of engine and generator.
• Tum off the engine by moving the Run/Stop switch to
STOP position.
OPERATING AUTOMATIC IDLE CONTROL
An Automatic Idle Control system provides greatly im-
proved fuel economy by operating the unit at itsnormal high
govemed speed only when electrical loads are plugged in
and tumed ON. The system consists of (a) an Idle Control
Circuit Board, (b) a Sensing Transformer, (c) an Electro-
magnet, and (d) an Idle Control Switch located on the
control panel (Fig. 8).

FIG. 8
Engine-generator runs at high governed speed with Idle
Control Switch ON only when an electrical load is con-
nected to the generator and turned on. When the electrical
load isdisconnected, an Electromagnet is energized to pull
the engine throttle control against itsidle stop. Engine then
runs at reduced (idle) speed.
The Electromagnet cannot be energized with Idle Control
Switch OFF, since its power circuit is open. Engine runs
at high govemed speed (about 3600 rpm) whether load(s)
are connected or not.
ADJUSTING AND SETTING IDLE CONTROL
You will need a volt-ohmmeter to adjust the idle control.
You can set and adjust the Idle Control on the Deluxe
Generator as follows:
Presetting Idle Control: Refer to the Idle Control Assem-
bly when you make the initial adjustment oi the idle Control.
• With the unit running and warmed up, tum the idle
control bolt clockwise (faster speed), or counterclock-
wise (slower speed) until the engine speed is between
25 and 35 Hz. (1500 - 2100 rpm). See Fig. 9.
• Lock the Idle Control Jam nut against the idle control
bracket, while the engine is still running at a range of
25 to 35 Hz.

Carburetor "Microadjusting": Once the idle control has
been preset, you can use the carburetor's idle screw to
make further =microadjustments" to the speed of the an-
gine-generator idle control.
• Turn the carburetor's idle screw clockwise (faster
_4Oezed ) until the engine speed is between 38 and 40
(2280 - 2400 rpm).
NOTE: Engine speeds of less than 38 Hz. could cause the
engine to stall if you apply sudden block loads.
BA'I-rERY SAFETY
A
WARNING: STORAGE BAI"rERIES GIVE OFF EX-
PLOSIVE HYDROGEN GAS WHILE CHARGING.
AN EXPLOSWE MIXTURE WILL REMAIN AROUND
BATTERY FOR A LONG 11MEAFTER IT HAS BEEN
CHARGED. THE SUGHTESTSPARK CAN IGNITE
GAS AND CAUSE AN EXPLOSION. SUCH AN EX-
PLOSION CAN SHATTER BATTERY AND CAUSE
BLINDNESS OR OTHER SERIOUS INJURY.
WARNING: DO NOT PERMIT SMOKING, OPEN
FLAME, SPARKS OR ANY OTHER SOURCE OF
HEAT AROUND A BAI"rERY. DO NOT USE A
UGHTER OR OTHER FLAME FOR CHECKING
BATfERY FLUID LEVELS. WEAR PROTECTIVE
GOGGLES, RUBBER APRON AND RUBBER
GLOVES WHEN WORKING AROUND A BATrERY.
BATTERY ELECTROLYTE FLUID IS AN EX-
TREMELY CAUSTIC SULFURIC ACID SOLUTION
THAT CAN CAUSE SEVERE BURNS. DO NOT
PERMIT FLUID CONTACT WITH EYES, SKIN,
CLOTHING, ETC. IF SPILL OCCURS, FLUSH
AREA WITH CLEAR WATER IMMEDIATELY.
