Output voltage should be checked periodically to
ensure continued proper operation of the generating
plant and appliances, it can be checked with a portable
meter. Frequency can be checked by using an electric
clock with a sweep second hand.
Timed against a wrist watch or a stop watch the
clock should be correct within +/- 2 seconds per
minute. All speed setting adjustments should be done
by a qualified technician.
GENERATOR CARE
The generator head is a two pole, 3600 RPM, 60
Hz, brushless, revolving field and synchronous type
with two sealed radial roller bearings.
Proper care and maintenance are necessary to
ensure a long trouble free life.
Exercising The Generator - The generator
should be operated every four weeks. Warm the
unit up by starting the engine and letting it run for 10 to
15 minutes. This will dry out any moisture that has
accumulated in the windings. If left, this moisture can
cause corrosion in the winding. Frequent operation of
the engine generator will also ensure that the set is
operating properly should it be needed in an
emergency.
Generator Maintenance - The generator head is
brushless and maintenance free. Any major generator
service including the installation or replacement of
parts should be performed only by a qualified electrical
service technician. USE ONLY FACTORY
APPROVED REPAIR PARTS.
A. Bearing - The bearings used in this generators
are a heavy duty, sealed roller bearing. They require
no maintenance or lubrication.
B. Receptacles - Quality receptacles have been
utilized. If a receptacle should become cracked or
otherwise damaged, replace it. Using cracked or
damaged receptacles can be both dangerous to the
operator and destructive to the equipment.
WARNING, Stand-by Operation
If your generator is to be used as a standby
electric power source in case of utility failure, it must
be installed by a registered and licensed electrician
and in compliance with all applicable state and local
electrical codes. Also, local Fire Departments must be
consulted concerning proper and safe handling
procedures for gasoline. NEVER connect any
generator to any existing electrical system without an
isolating, UL approved transfer switch, installed by a
licensed electrician.
