POTENTIAL CAUSE
SOLUTION
Engine runs erratically
or does not hold steady
speed.
1. Engine is not warm enough.
1. Disconnect all electrical cords and appliances from
generator and switch all AC circuit breakers OFF. Re-
start generator and allow to run for at least 2 minutes
after choke lever has been moved to the OFF position
before reconnecting electrical loads.
2. Choke lever is in the ON
position and engine is already
warm or hot.
2. Move the choke lever to the OFF position.
3. Fuel is stale or contaminated.
3. Drain fuel and refill with fresh fuel.
4. Air filter is dirty or blocked.
4. Check air filter element and clean if necessary.
5. Electrical load cycling on and
off.
5. Engine speed may vary slightly when electrical load
changes; this is normal operation. No fault.
6. If above possible causes
are checked and eliminated,
generator may be faulty.
6. Take generator to an authorized Westinghouse
service dealer.
The engine emits a
metallic “pinging” sound.
1. This sound my be heard
occasionally when the
generator is operating under
heavy load.
1. This is normal operation. No fault.
2. If this sound is heard
frequently when the generator
is operating under normal
load:(a) the fuel may be
unsuitable or contaminated,
or (b) the spark plug may be
unsuitable or fouled.
2. (a) Drain fuel and refill with fresh fuel of the correct
type from a known source. (b) Replace spark plug with
a new one of the correct type.
3. If above possible causes
are checked and eliminated,
generator may be faulty.
3. Take generator to an authorized Westinghouse
service dealer.
RCD safety switch turns
itself
OFF
(if equipped).
1. Electrical fault in connected
cord(s) or device(s).
1. Disconnect all electrical cords and devices from
generator and switch all 240-Volt AC circuit breakers
OFF. Reset RCD safety switch to ON position.
Reconnect and test run 240-Volt AC loads individually.
Any faulty cord or device that trips the RCD safety
switch again must not be used further until checked
and approved by a licensed electrician.
2. If above possible cause is
checked and eliminated,
generator may be faulty.
2. Take generator to an authorized Westinghouse
service dealer.
Main 240V-AC circuit
breaker turns itself off.
1. Electrical overload or short
circuit in connected cord(s) or
device(s).
1. Disconnect all electrical cords and devices from
generator and switch all 240-Volt AC circuit breakers
OFF. Check RCD safety switch is in ON position (if
equipped). Reconnect and test run 240-Volt AC loads
individually. Any single cord or device that trips the
main circuit breaker again is either faulty or too great
a load for the generator. Any faulty electrical device
must not be used further until checked and approved
by a licensed electrician. Check running and starting
power demands of total connected electrical load
versus generator’s rating.
2. If above possible cause is
checked and eliminated,
generator may be faulty.
2. Take generator to an authorized Westinghouse
service dealer.
