ECOSpeed Engine
The unit is equipped with an ECOSpeed engine that runs
at variable speeds depending on the applied operational
load. Operating temperature remains constant regardless
of engine speed or applied loads.
• The engine runs at low speed when the LED lights
are operating and the 240VAC/30A main breaker is
OFF. Lower speed conserves fuel, reduces emissions and sound output, and extends total run time.
• The engine runs at high speed when the LED lights
are turned on and the 240VAC/30A main breaker is
ON. Higher speed maximizes export of clean 60 Hz
power to the convenience outlets.
Refer to Operation for more information.
(G) 240VAC/30A receptacle
Customer convenience receptacle for use in connecting
auxiliary equipment such as fans, pumps, or drills.
(H) 240VAC/30A main breaker
• Enables high speed engine operation for 60 Hz
export power.
• Circuit protection for 30A twist lock outlet; circuit
feed for 20A outlet breaker.
(J) Automatic Load Sense switch
Automatic Load Sense works in tandem with the
ECOSpeed™ engine to adjust engine operating speed
according to lighting and export power requirements. The
240VAC/30A main breaker (H) must be ON to enable
Automatic Load Sense.
• Turning Automatic Load Sense switch ON
enables Automatic Load Sense—the default
setting for normal export power operation.
• Turning Automatic Load Sense switch OFF
disables Automatic Load Sense and allows the
engine to run at high speed when the 240VAC/30A
main breaker (H) is ON. Use this setting when
connecting equipment that requires a higher
starting amperage, such as air conditioners, air
compressors, or submersible pumps.

PowerZone–DLA
The PowerZone–DLA is an auto start controller that
monitors the unit and indicates operational status and
fault conditions. The controller can be programmed to
automatically start or stop based on time schedule, fault
condition, or load demand.
The controller constantly monitors vital generator and
engine functions for a number of preprogrammed alarm
and fault conditions. When a fault condition occurs, the
engine will be shut down automatically and the LCD
window will show the fault that caused the shutdown. The
fault condition must be corrected to resume operation.
This controller records a history of unit performance,
which may be viewed at any time, and will not be lost
when the controller is powered down.

• Warnings are non-critical alarm conditions and do
not affect the operation of the generator system.
They serve to draw the operator’s attention to an
undesirable condition. By default, warning alarms
are self-resetting when the fault condition is
removed.
• Electrical trips stop the generator in a controlled
manner. On initiation of the electrical trip condition,
the controller de-energizes all the outputs, including the lights, to remove the load from the generator. Once this occurs, the controller starts the
cooling timer and allows the engine to cool off-load
before shutting down the engine.
• Shutdown alarms stop the generator immediately.
On initiation of the shutdown condition, the controller de-energizes all the outputs, including the lights,
to remove the load from the generator. Once this
occurs, the controller shuts the generator set down
immediately to prevent further damage.

performance decreases about 1% for every 10 ºF (5.6
ºC) increase in ambient air temperature over 72 ºF (22
ºC).
Wet Stacking
The ECOSpeed engine in this unit eliminates the adverse
effects of “wet stacking” caused by prolonged operation
of a cold, lightly-loaded diesel engine. These include:
• fuel dilution
• sooting with heavy, black exhaust
• moisture accumulation
Engine temperature and speed are continuously managed to avoid developing a wet stack condition.

Trailer Wheel Bearings
The trailer axles are equipped with a Zerk grease fitting
to allow lubrication of the wheel bearings without the
need to disassemble the axle hub. Use only a high
quality grease made specifically for lubrication of wheel
bearings, such as Valvoline
Proceed as follows to lubricate the wheel bearings:
1. See Figure 4-2. Remove the small rubber plug (A)
from the metal end cap (B).
®
W615 or equivalent.
After First
Operation
The minimum recommended lubrication is every 12
months or 12,000 mi (19,312 km). More frequent
lubrication may be required under extremely dusty or
damp operating conditions.
Every six months, or depending on usage, inspect for
play in each bearing by jacking up the trailer, then trying
to rock the wheel. If further assistance is required, contact Generac Mobile Products Technical Service at 1800-926-9768.
Before Each
Use
Semi-Annually
Figure 4-2. Wheel Bearing Cross Section
2. Attach a standard grease gun fitting to the Zerk
grease fitting (C).
3. Pump grease into the Zerk fitting until fresh grease
is visible around the nozzle of the grease gun.
4. Wipe any excess grease from the axle hub with a
clean cloth and install the rubber plug.
Jack Maintenance
Inspect each jack foot before each use for damage and
remove any mud or debris. The jacks must be clean and
in good operating condition to properly support the unit.
