GA-4.5R/GA-4.5RA   — CONTROLS AND INDICATORS

Figure 2A.  Generator Controls and Components

1

.

Lifting Bail Eye –

  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
eye in down position when not in use.

2

.

AC-Voltmeter –

  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

OFF

 and consult your authorized 

MQ

 service dealer.

3

.

Idle Control Switch –

 This unit is provided with an

automatic idle control 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 2600 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.

4

.

Operation Switch –

  Place this 

rocker

 switch in the "

RUN

"

position (up) for normal operation. To turn-off the generator
place this switch in the "

STOP

" position (down).

5

.

GFCI Duplex Receptacle –

  NEMA 5-20R receptacle will

provide 120V, 20 amps. The position of the full power switch
does not effect the voltage output at the receptacle. The
GA-4.5RA has two GFCI receptacles.

6

.

120 VAC  Receptacle  –

  NEMA L5-20R twist-lock

receptacle will provide 120V, 20 amps  when the full power
switch is placed in either the 120 or 240 volt position.

7

.

120 VAC Receptacle  –

  NEMA L5-30R twist-lock

receptacle will provide 120V when the full power switch is
placed in either the 120 or 240 volt position.

8

.

240 VAC  Receptacle  –

  NEMA L14-20R twist-lock

receptacle will provide 240V when the full power switch is
placed in the 240/120 volt position (down). When the full
power switch is placed in the 120 volt position (up), 120V
will be available.

9

.

Main Circuit Breaker –

 2-pole circuit breaker (240V/18.75

amps or 120V/30.8 amps) protects the generator from short
circuiting or overloading. When starting the generator

always

 have the circuit breaker placed in the "

OFF

"

position.

10

. Frame Ground –

  This ground connection point should

be connect to a good earth ground (ground rod).
