STOPPING
1. Disconnect all loads to generator.
2. Move engine on-off switch to the O position.
ENGINE CARE
Refer to your Tecumseh Owner’s Manual for
proper care and maintenance.
CAUTION NEVER change oil on a hot
engine, the hot oil could cause severe burns.
GENERATOR CARE
The generator head is a two pole, 3600 RPM, 60
Hz, brushless, revolving field and synchronous type
with one sealed radial roller bearing. The rotor of the
generator head is directly connected to the engine
crank shaft and the stator is rigidly coupled to the
engine casting via the generator head casting.
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. Obtain all factory parts
from Customer Service at 1-800-270-0810.
A. Bearing - The bearing used in these generators
is a heavy duty sealed ball 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.
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.
