Section 4: Maintenance and Troubleshooting
Daily Walk-Around Inspection
Perform a walk-around inspection of the unit every day
before starting the unit. Look for conditions that could
hinder performance or safety, such as (but not limited to)
damaged or missing parts and hardware, and loose or
broken electrical connections.
General Maintenance
Poorly maintained equipment can become a safety
hazard. In order for the equipment to operate safely and
properly over a long period of time, periodic maintenance
and occasional repairs are necessary.
DO NOT
perform
routine service unless all electrical components are OFF.
Regular maintenance will improve performance and
extend engine/equipment life. Generac Mobile Products,
LLC recommends all maintenance work be performed by
an Generac Mobile Products Authorized Dealer (ASD).
Preparing for Service
Before servicing the unit, always follow the instructions
listed below.
1.
Verify unit power switch is OFF.
2.
Disconnect power.
3.
Disconnect water supply.
4.
Attach a DO NOT USE sign to the control panel.
This will notify everyone that the unit is being
serviced and will reduce the chance of someone
inadvertently trying to start the unit.
Inspecting the Unit

If the unit is stored outside, check for water inside
the cabinet and control panel cover before each
use. If wet, dry the unit thoroughly before starting.
•
Inspect condition of electrical cords.
DO NOT
use
the unit if insulation is cut or worn through.
Cleaning the Unit
Always clean the unit after each use to remove dust,
grease, mud or spilled fuel or oil. fter each use, clean the
unit if dust, grease, or dirt. Use soft, clean rags to wipe
the cabinet exterior and control panel. Low-pressure
compressed air (less than 40 PSI [276 kPa]) can also be
used to remove dust and debris from control panel.

Do not use a high pressure hose or power
washer to clean control panel or cabinet. Water could
damage the electronic components.
