HIGH ALTITUDE OPERATION

At high altitude, the carburettor air / petrol mixture is very rich,
causing a drop in engine performance and an increase in fuel
consumption.
When using the generator at an altitude of over 1 800 metres above
sea level, a smaller diameter jet needs to be fitted to the carburettor
and the pilot screw adjusted. This must be carried out by your
Honda dealer.
In spite of a proper adjustment to the fuel feed system, engine
power will still decrease by 3.5 % for every 300 metre increase in
altitude.
GENERATING SET USE
Your Honda generator is a reliable piece of equipment, developed
to ensure your safety. It can help you carry out work more easily and
bring improvements to your leisure time, but there is also a risk of
electrocution if you do not follow strictly the instructions for use
given in this chapter.
The generator produces
enough electric power to cause
a serious shock or electrocution
if misused. Be sure to ground
the generator [1] when the
connected appliance is
grounded.
To ground the terminal of the
generator, use a cooper wire
with same or larger diameter
than the cord of the connected
appliance.
Use extension cord set with
ground conductor when connecting an appliance with ground
conductor.
To identify the Ground pin in the plug, see "Receptacle"
Connect a RCBO (Residual current circuit breaker with overload
protection) of 30 mA ground fault detection and cut-off of less than
0.4 seconds at more than 30 A of out put current, if you are using
two or more appliance.
Follow the instructions provided by each RCBO manufacturer
before use.

• Improper connections to a building's electrical system can
allow current from the generator to backfeed into the utility
lines. Such backfeed may electrocute utility company
workers or others who contact the lines during a power
outage, and the generator may explode, burn, or cause fires
when utility power is restored.
Consult the utility company or a qualified electrician prior to
making any power connections.
• Do not connect any appliances to the receptacles before
• Do not alter the internal wiring of the generator.
• Do not alter the engine settings: the voltage and frequency
• Only connect appliances in good working order: most

safety of the user. Cables must be inspected regularly; they
should be replaced, and not repaired, in the event of a defect.
