ENGINE OIL REPLENISHMENT SYSTEM
This unit is equipped with an engine oil replenishment system. The system eliminates the need for frequent filling
and checking of the crankcase. The system consists of a oil reservoir tank and an oil level regulator. The regulator
is mounted so the centerline of the sight glass is at the same height as the level of the oil in the crankcase. When
the engine oil level is low, the float will trigger the reservoir tank to send fresh oil to the crankcase. The regulator
delivers only that amount of oil required to maintain a constant oil level in the crankcase. A fine mesh screen in the
regulator provides protection against damage by contaminants and abrasive foreign matter.
The regulator is pre-set to the correct level at the factory and should not require adjustment. See
for more information.
DERATING FOR ALTITUDE
All units are subject to derating for altitude and temperature; this will reduce the available power for operating tools
and accessories connected to the receptacles. Typical reductions in performance are a derate of -3% for every 1000
ft (305 m) above 1200 ft (366 m) above sea level and a derate of -1% per 10°F (-12ºC) increase in ambient air
temperature over 77°F (25°C).
GENERATOR OUTPUT CONNECTIONS
The unit is equipped with lug connections, located inside the customer connection box. The connection box is located
behind the door on the right side of the unit. See
. The lugs provide connection points for attachment of
external loads to the generator.
DANGER
RISK OF ELECTROCUTION. BEFORE ANY CONNECTIONS ARE MADE TO THE
GENERATOR, VERIFY THE MAIN CIRCUIT BREAKER AND THE BATTERY DISCON-
NECT SWITCH ARE OFF (O). POTENTIALLY LETHAL VOLTAGES MAY BE PRESENT
AT THE GENERATOR CONNECTION LUGS.
WARNING
Only a trained and licensed electrician should perform wiring and connections to
unit. Failure to follow proper installation requirements could result in death, serious
injury, and damage to equipment or property. (000155)
Connections to the lugs should be made by running the power cables up through the opening in the bottom of the
box.
DO NOT
make any connections directly to the lugs without routing the cables through the slot. Use a hex-wrench
to tighten the cable connections.
The connection box door is equipped with a safety interlock switch that will trip the main circuit breaker and disable
the voltage regulator if the door is opened while the unit is operating.
DANGER
ELECTROCUTION. DO NOT DISABLE OR MODIFY THE CONNECTION BOX DOOR
SAFETY SWITCH. DOING SO WILL RESULT IN DEATH OR SERIOUS INJURY. (000157)
A ground connection is located next to the lugs. The generator neutral is bonded to ground when it is shipped from
the factory. The bonding plate may need to be removed if the generator is used as a standby power source.
INSTALLATION SHOULD BE IN COMPLIANCE WITH THE NATIONAL ELECTRICAL CODE (NEC), STATE AND
LOCAL REGULATIONS.
