Starting/Stopping Engine; Connecting Electrical Loads; Operation - Generac Power Systems WHEELHOUSE 1646-3 Owner's Manual

OPERATING THE
GENERATOR
CAUTION
Exceeding generators wattage/amperage capacity can
damage generator and/or electrical devices connected
to it.
• See "Don't Overload Generator".
• Start generator and let engine stabilize before connecting
electrical loads.
• Connect electrical loads in OFF position, then turn ON for

operation.

• Turn electrical loads OFF and disconnect from generator
before stopping generator.
Starting the Engine
Disconnect all electrical loads from the generator. Follow
these start instruction steps in numerical order:
1. Make sure unit is on a level surface.
IMPORTANT: Failure to start and operate unit on a level
surface will cause the unit not to start or shut down during
operation.
2. Make sure the fuel line quick connect is hooked up and
that all four tank hold-downs are firmly tight.
3. Turn the vent knob fully counter-clockwise. See
Figure 2 on page 7.
4. Rotate the fuel valve to the "On" position. See
Figure 3 on page 7.
5. Start the engine according to instructions given in the
engine owner's manual.
WARNING
Rapid retraction of starter cord (kickback) will
pull hand and arm toward engine faster than
you can let go.
Broken bones, fractures, bruises or sprains could
result.
• When starting engine, pull cord slowly until resistance is felt
and then pull rapidly to avoid kickback.
• NEVER start or stop engine with electrical devices plugged in
and turned on.
NOTE: If engine starts after 3 pulls but fails to run, or if
unit shuts down during operation, make sure unit is on a
level surface and check for proper oil level in crankcase.
This unit may be equipped with a low oil protection device.
See engine manual.

WARNING
Running engines produce heat.Temperature of
muffler and nearby areas can reach or exceed
150°F (65°C).
Severe burns can occur on contact.
Combustible debris, such as leaves, grass, brush,
ect. can catch fire.
• DO NOT touch hot surfaces.
• Allow equipment to cool before touching.
• The generator must be at least 5 feet from structures having
combustible walls and/or other combustible materials.
• Keep at least 3 feet of clearance on all sides of generator for
adequate cooling, maintenance and servicing.
• In the State of California a spark arrester is required by law
(Section 4442 of the California Public Resources Code). Other
states may have similar laws. Federal laws apply on federal
lands. If you equip the muffler with a spark arrester, it must be
maintained in effective working order.

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 Hz electrical loads.
• DO NOT connect 240 Volt loads to the 120 Volt
receptacles.
• DO NOT connect 3–phase loads to the generator.
• DO NOT connect 50 Hz loads to the generator.
• DO NOT OVERLOAD THE GENERATOR. See
"Don't Overload Generator".
Stopping the Engine
1. Unplug all electrical loads from generator panel
receptacles. NEVER start or stop engine with electrical
devices plugged in and turned on.
2. Let engine run at no–load for 30 seconds to stabilize
internal temperatures of engine and alternator.
3. Turn engine off according to instructions given in
engine owner's manual.
4. Move fuel valve to "Off" position.
