STARTING
IMPORTANT: The loaded engine speed is preset. The throttle is
locked in preset position. Do not adjust throttle. Preset position lets
engine run at 3600 RPM under load. The engine must maintain
3600 RPM for generator to create correct voltage. Running engine
at lower speeds will damage generator and powered items.
IMPORTANT: Never start generator with electrical loads con-
nected. Start engine before adding electrical loads.
OPERATION INSTRUCTIONS
1. If the engine is cold, turn 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. En-
gine 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.
6. Auto-Idle system should be turned off when generator is shut
down.
WARNING: Only responsible adults should use
generator. Never let anyone operate generator with-
out proper instructions.
PRESTART
Operate generator on a firm, dry, and clean surface. The surface
must be level. Protect generator from heavy dust, sand, dirt, rain, or
snow. Do not locate generator near standing water and snow. Make
sure area is well-vented.
Note: If oil level is too low, oil alert system will keep engine from
starting (see Oil Alert System in owner's manual, page 8). Make sure
oil level is full before starting. See Engine Oil in owner's manual,
page 8.
Before starting the engine, disconnect all electric loads from
generator.
STOPPING ENGINE
IMPORTANT: The loaded engine speed is preset. The throttle is
locked in preset position. Do not adjust throttle.
Follow the steps below to stop engine.
1. Remove all electrical loads from generator (see Disconnect-
ing Electrical Loads in owner's manual, page 13). Remove
electrical loads one at a time.
2. Let engine run for two or three minutes after removing elec-
trical loads. This lets engine cool slightly.
3. Turn engine switch to the OFF position (see Figure 1 and 2).
4. Turn fuel valve lever off. Do this by moving valve lever fully
to the left (see Figure 3).
