INSTALLATION
If possible install the generator in a area that is free of
debris, bystanders, and overhead obstructions. Make sure
the generator is on secure level ground so that it cannot
slide or shift around.
The installation site must be relatively free from moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and
grounding.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
Exhaust gases from gas engines are extremely poisonous.
Whenever an engine is installed indoors the exhaust
fumes must be vented to the outside. The engine should
be installed at least two feet from any outside wall. Using
an exhaust pipe which is too long or too small can cause
excessive back pressure which will cause the engine to
heat excessively and possibly burn the valves.
The generator should always be placed on a flat level
surface when it is running. DO NOT place the generator
on slopes, the possibility exists that the generator could
slide.
Pay close attention to ventilation when
operating the generator inside tunnels
and caves. The engine exhaust contains
noxious elements. Engine exhaust must
be routed to a ventilated area
Electric shock can occur when vibrators
are used. Pay close attention to handling
when operating vibrators and always use
rubber boots and gloves to insulate the
body from a short circuit.
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good eaRTH
ground.
Article 250 (Grounding) of the National Electrical Code
(NEC) provides guide lines for proper grounding and
specifies that the cable ground shall be connected to the
grounding system of the building as close to the point of
cable entry as practical.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generator to earth ground.
a. Copper - 10 AWG (5.3 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
2. When grounding the generator (Figure 3) connect the
ground cable between the lock washer and the nut on
the generator and tighten the nut fully. Connect the
other end of the ground cable to earth ground.
3. NEC article 250-52(c) specifies that the earth ground rod
should be buried a minimum of 8 ft. into the ground.
NOTICE
When connecting the generator to any buildings
electrical system consult with a licensed
electrician.

1. NEMA 5-20R, GFCI
receptacle will provide 120V@ 20 amps.
2. Indicates the number hours the generator
has been in use.
3. Attach a rope or chain to this lifting
eye when lifting of the generator is required. Never
stand underneath the generator while it is being lifted.
Place lifting bail in down position when not in use.
4. Interrupts power when a
ground fault exist.
5. This 2-pole, 15 amp circuit breaker
protects the generator from short circuiting or
overloading. When starting the generator always have
the circuit breaker placed in the "" position.
6. This voltmeter indicates (with a
mark) the rated 60 Hz (single-phase) output voltage.
In addition the voltmeter can also be used as a
diagnostic tool. If the voltmeter indicator (needle) is
below the rated voltage, engine problems may exist
(low/high RPM's).To prevent damage to the generator
or power tools turn the generator and consult your
authorized Multiquip service dealer.
7. The generator is provided with
an automatic idle control device for noise suppression
and reduced fuel consumption.
The automatic idle control automatically engages under
a no-load condition. With the automatic idle control
switched “ON”, the engine revolutions will automatically
drop to about 2500 rpm (low-speed operation) within
3 seconds after the load stops. When the operation is
resumed, the engine speed is automatically increased
to about 3600 rpm (high-speed operation) as soon as
the load is connected.
8. Place switch in the "ON" position
(up) for normal operation. To turn-off the generator,
place the operation switch in the "OFF" position (down)
9. NEMA L14-30R twist-
lock receptacle will provide 240V, 60 Hz @ 13.3 amps,
or 120V@ 26.7 amps (X2) 60 Hz. Depending on the
position of the full power switch.
10. NEMA L5-30R twist-lock
receptacle will provide 120V, 30 amps, 60 Hz.
11. NEMA L5-20R twist-lock
receptacle will provide 120V, 20 amps, 60 Hz.
12. A container filled with activated
charcoal that traps gasoline vapors emitted by the
fuel system.
13. This ground connection point should be
connect to a good earth ground (ground rod).

COMPONENTS (GENERATOR)
14. The generator is provided with a
full power switch. Figure 6 and Figure 7 show simplified
wiring diagrams of the dual voltage system.
When the full power switch is in the 120 volt (up)
position, you can access the full rated power of the
generator at 120 volts from the GFCI duplex receptacle
and the120V twist-lock receptacle, or a combination
of both receptacles as long as the total load does not
exceed the generating set capacity.

When the full power switch is in the 120V position, the
240V twist-lock receptacle cannot be used..
When the switch is in the 240 volt (down) position, you can
access half of the rated power of the generating set at 120
volts from the GFCI duplex receptacle and up to half of the
rated power of the set at 120 volts from 120V twist-lock
receptacle; or full rated power of the set at 240 volts from
the 240V twist-lock receptacle.
