Operation (Continued)
AUTO-IDLE OPERATION
IMPORTANT: Never start engine with
electrical loads connected. Start engine
before adding electrical loads.
1. If engine is cold, turn the auto-idle
switch OFF.
2. Start engine. Allow engine to warm up
with no load for five minutes.
3. Turn auto-idle switch ON. Engine will
slow to idle speed. Engine idle speed is
preset. Idle speed adjustment should
not be necessary.
4. Operate generator according to
specifications outlined in owner's
manual.
5. Engine will automatically increase to
normal operating speed when you plug
load into any generator outlet.
NOTE: The 250 Volt/50 Amp receptacle is
not connected through the auto-idle
circuit. The auto-idle switch must be
turned off to get full power out of this
receptacle (See Figure 30).
6. The auto-idle system should be turned
OFF when generator is shut down.
ADJUSTING THE IDLE SPEED
IMPORTANT: Adjust the idle speed only:
• If the idle speed becomes too high.
• If the engine idle speed will not
regulate (engine idles and speeds up
again and again).
1. Turn auto-idle switch OFF. Start engine.
Allow engine to warm up with no load
for five minutes.
2. Remove engine linkage cover (Models
5U936D and 3W739D only).
3. Push plunger into solenoid body to
manually engage solenoid and set idle
speed.
4. Loosen the M8 nut that holds the
solenoid mounting bracket to the
generator (Models 5U936D and
3W739D only, See Figure 31). Do not
loosen bolt that holds the solenoid
mounting bracket to the generator on
Model 3LW64A, See Figure 32).
