OPERATION

OTE:

N

If the engine fails to start after 5 seconds, 

release the engine control switch. Let the 

generator rest for 15 seconds and then 

repeat step 5. If the cranking speed drops 

after each unsuccessful attempt, the 

battery may not be adequately charged; 

manually start the generator as instructed 

in Manually Starting a Generator on page 

21.

OTE:

The electric start generator is equipped 

with a battery charging feature. Once 

the engine is running, a small charge is 

supplied to the battery via the battery 

cables and will slowly recharge the battery. 

1.  As the engine starts and stabilizes, gradually move 

the choke lever back to the OFF position.

2.  Connect electrical cords or devices into the 240-

Volt AC and/or 12-Volt DC outlets, as required. 

Switch the 240-Volt AC Main Circuit Breaker to 

the ON position and then switch the 240-Volt AC 

Circuit Breakers for Outlets A and B (if equipped) 

to the ON position; allow a few seconds between 

switching on Outlets A and B so that the generator 

can stabilize.

Normal Operation

During normal operation, use the following steps to 

stop the generator:

1.  Switch the 240-Volt AC Circuit Breakers for Outlets 

A and B (if equipped) to the OFF position and 

then switch the 240-Volt AC Main Circuit Breaker 

to the OFF position. Unplug any electrical cords 

or devices from the 240-Volt AC and 12-Volt DC 

receptacles on the control panel.

2.  Allow the generator to run unloaded for at least 

one minute to cool and stabilize the engine and 

alternator temperatures.

3.  Push the engine control switch to the OFF 

position.

4.  Turn the fuel shutoff valve to the OFF position.

During an Emergency

If there is an emergency and the generator must be 

stopped quickly, push the engine control switch to the 

OFF position immediately.

All models within this range of Westinghouse 

generators are portable, air-cooled, petrol-engine 

driven, self-contained units designed for independent 

supply of electrical power. They are ideal for 

applications requiring an occasional backup power 

supply in the event of mains power failure such as 

home or small business standby duty. They are 

equally well suited for remote or on-site applications 

such as camping, caravanning and mobile field 

service/trade duty that have an intermittent 

requirement for electrical power.

Other applications requiring an independent electrical 

power supply on a constant 24/7 or frequently 

recurring multi-hour basis are better served by 

industrial, water-cooled, diesel-engine driven 

generators. Typically these are larger and heavier 

stationary units that cannot be manhandled and may 

require some installation work including connection by 

a licensed electrician.

aMBiEnt ConDitions

The generator is designed to operate within the 

following range of ambient conditions:

• 

Temperature:  -5 to +40°C

• 

Altitude: 

Up to 1,000 m

Where possible, the generator should be operated in 

the shade to prevent additional heat load due to solar 

radiation.

The engine’s power output will decrease by 

approximately 3.5% for each 300 m increase in 

altitude above sea level. This is normal for spark-

ignition engines and is attributable to the decrease in 

atmospheric pressure (and thus the available air for 

combustion) as altitude increases.

The generator can only be used to power 240-Volt AC, 

50 Hz, single phase or 12-Volt DC electrical devices. 

240-Volt AC Loads

240-Volt AC devices can be connected either directly 

or via electrical extension cords into the 240-Volt AC 

outlet(s) on the generator’s control panel. Lift up the 

spring-loaded weather resistant cover on each outlet 

for access to connect the electrical device or cord.

240-Volt AC devices may be fitted with either a three-

pin 15 Ampere (typically abbreviated “15 Amp” or “15 

A”) plug or a three-pin 10 Ampere (“10 Amp” or “10 A”) 

plug as shown in Figure 23. Certain double-insulated 

devices may be fitted with a two-pin 10 A plug that 

doesn’t have an earth pin (which is the longer, vertical 

pin).
