Problem
Cause
Solution
Engine starts and shuts off right away.
If equipped, when CO Shield® shutoffs
occur due to accumulating carbon
monoxide (CO) and if the red LED light
blinks on the panel.
Move generator to an open, outdoor area. Point
exhaust away from people and buildings. Move
to fresh air and get medical help if sick, dizzy, or
weak.
Make sure there are no objects creating
obstructions within 5 feet of the generator.
Obstructions in the vicinity of the generator
may trap carbon monoxide emissions near the
generator and cause the engine to shutoff.
If the generator’s exhaust is facing into the
wind, the exhaust may be blown back into
the generator’s operating area, creating an
accumulation of CO emissions and triggering an
engine shutoff. To avoid an engine shutoff, turn
the generator 45° in either direction to allow
the exhaust emissions to blow away from the
generator. If engine shutoff events continue,
readjust and align the exhaust with the wind
direction to blow away from the generator.
If equipped, when CO Shield® shutoffs
occur due to system fault and if the
yellow LED light blinks on the panel.
Start by confirming yellow LED light blinks when/
if generator shuts off. If CO Shield® continues to
sense the fault and shuts off, contact technical
support.
