Emissions Information
For emissions information, see the OEM diesel engine
manual.
Maintenance
Regular maintenance ensures correct machine
performance and extends engine/equipment life.
Generac Mobile recommends that all maintenance work
be performed by a GMASD. Regular maintenance,
replacement, or repair of the emissions control devices
and systems may be performed by any repair shop or
person of the owner’s choosing. To obtain emissions
control warranty service free of charge, the work must be
performed by a GMASD. See the emissions warranty.
Daily Walk Around Inspection
•
Inspect for conditions that could hinder
performance or safety, such as (but not limited to)
proper oil, coolant, DEF and fuel levels, blocked
vents, loose or missing hardware, and improper
electrical connections. When engine is stopped
and completely cool, coolant may be added directly
to the radiator.
•
Oil may also be added directly to the fill tube. See
the OEM engine manual for the proper viscosity
grade of oil, including special operating conditions
such as a change in season or climate. DO NOT
start the unit if the engine oil level is below the add
mark on the dipstick. Normal operating level is in
the cross-hatch pattern between the FULL and
ADD markings on the dipstick. Add oil only if the oil
level is below the ADD mark on the bottom of the
cross-hatch pattern on the dipstick. DO NOT
OVERFILL the crankcase.
•
Inspect the fan belt for signs of cracking, fraying,
and stretching, and verify the belt is properly
seated in the pulley grooves. Replace the belt
according to the manufacturer’s recommendations.
•
Inspect containment basin and properly dispose of
any fluid in containment basin.
•
Verify the condition of the air filter by viewing the
level of the vacuum draw on the filter minder
gauge. Replace the air filter when the yellow center
bar reaches the red section on the gauge (20 in.
H2O).
•
Inspect condition of electrical cords. DO NOT use
the unit if insulation is cut or worn through.
•
Check tire pressure, lug nut torque, and axle oil
bath levels according to manufacturers
recommendations. If unit is going to be stationary
for extended period daily checks of the wheels and
axles are not required. If unit has been stationary
for an extended period and will be transported, a
thorough inspection is necessary to ensure wheels
and axles are in proper working order. Inspect the
wheel bearings for unusual wear. See Trailer
Wheel Bearings .
NOTE: If the engine was run out of fuel, or the fuel tank
was drained, it may be necessary to purge the fuel lines.
See the OEM engine manual supplied with the unit for
more information.
General Maintenance
Poorly maintained equipment can become a safety
hazard. Periodic maintenance and occasional repairs are
necessary in order for the equipment to operate safely
and properly over a long period of time. Never perform
any routine service (such as oil and oil filter changes,
cleaning) unless all electrical components are shut off.
Before servicing the unit, always follow the instructions
listed below.
•
Verify the controller power switch is OFF (O).
•
Verify the battery disconnect switch is OFF (O).
•
Verify the circuit breakers are OFF (O).
•
Activate (push in) the E-Stop switch.
•
Disconnect battery negative (-) cable.
•
Attach a DO NOT USE sign to the control panel.
This signifies that the unit is being serviced and
reduces the chance of someone inadvertently
trying to start the unit.
•
If the unit is connected to a remote start or transfer
switch, verify the remote switch is OFF and tagged
with a DO NOT USE sign.
•
ONLY power wash the unit exterior. Do NOT power
wash any part of the unit interior.
•
Do not wash the engine block or fuel tank with a
power washer or steam cleaner. Water may enter
the cabinet and collect in the generator windings or
other electrical parts, causing damage.
•
Inspect coolant system for leaks.
CAUTION
Equipment Damage. Failure to perform a daily
inspection could result in damage to the unit.
