Connecting Electrical Loads; Operating The Generator; Starting The Engine; Stopping The Engine - Generac Power Systems 4000XL Owner's Manual

OPERATING THE
GENERATOR
CAUTION!
Never start or stop the engine with
electrical loads connected to the unit and with the
connected devices turned ON.

Starting the Engine

Disconnect all electrical loads from the generator. Use the
following start instruction steps by numerical order:
1. Make sure the Idle Control switch is in "Off" position.
2. Turn the fuel valve to the "On" position (Figure 3).
Figure 3 — Fuel Valve in Open Position.
3. Set the Run/Stop switch to "Run" position (Figure 4).

4. Place the choke lever in the "Full" choke position
(Figure 5).

5. Grasp the recoil handle and pull slowly until slight
resistance is felt. Then pull rapidly one time only to
start engine.
• If engine starts, proceed to step 7.
• If engine fails to start, proceed to step 6.
6. Move the choke lever to "Half" choke position, and
pull recoil handle twice.
• If engine fails to start, repeat steps 4 thru 6.
7. Move choke lever to "Run" position. If engine falters,
move choke lever to "Half" choke position until the
engine runs smoothly, and then to "Run" position.
NOTE: If engine still fails to start after 3 pulls, check for
proper oil level in crankcase. This unit is equipped with a
Low Oil Shutdown System. See engine manual.

Connecting Electrical Loads

• Let engine stabilize and warm up for a few minutes after
starting.
• Plug in and turn on the desired 120 and/or 240 Volt AC,
single phase, 60 Hertz electrical loads.
• Do Not connect 240 Volt loads to 120 Volt receptacles.
• Do Not connect 3–phase loads to the generator.
• Do Not connect 50Hz loads to the generator.
• DO NOT OVERLOAD THE GENERATOR. Add up
the rated watts (or amps) of all loads to be connected at
one time. This total should not be greater than the rated
wattage/amperage capacity of the generator. See "Don't
Overload the Generator" on page 11.

Stopping the Engine

• Unplug all electrical loads from generator panel
receptacles. Never start or stop engine with electrical
devices plugged in and turned on.
• Put the Idle Control switch in the "Off" position.
• Let engine run at no–load for 30 seconds to stabilize the
internal temperatures of engine and generator.
• Move Run/Stop switch to "Stop".
• Close the fuel shut–off valve.
