WARMING UP
Be sure to warm up the engine, not only in winter, but
also in warmer seasons. An insufficiently warmed-up
engine can shorten its service life.
a Warm-up in the Low Temperature Range
In cold weather, the engine oil may be cold with
increased viscosity. This can delay oil circulation or
abnormally low oil pressure for some time after
engine start-up. This can result trouble in the
lubrication circuit or damage to the engine moving
parts.
To prevent the above problems, perform the
following instructions:
Warm up the engine at rated revolution with no load.
Ambient temperature
Above 0ºC (32ºF)
0ºC (32ºF) to –10ºC (14ºF)
Below –10ºC (14ºF)

WARNING
WARNING:
To avoid personal injury:
¡ Before the generator can be
connected to a building's electrical
system, a licensed electrician must
install an isolation (transfer) switch
in the building's main fuse box. The
switch is the connection point for
generator power and allows
selection of generator or main line
power to the building. This will
prevent the generator from
charging the main power line
(backfeeding) when the main
power supply has failed or has
been turned off for line repair.
Backfeeding can electrocute or
injure line maintenance personnel.
Also, generator and building
electrical system damage can
occur when normal operating
power returns if unit is used
without an isolation switch.
1. Avoid connecting the generator to commercial
power outlet.
2. Avoid connecting the generator in parallel with
any other generator.
