Section 4: Maintenance
Daily Walk-Around Inspection
CAUTION
(000306)
Equipment Damage. Failure to perform a daily
inspection could result in damage to the unit.
Perform a walk-around inspection of the unit before each 
use. Look for conditions that could hinder performance or 
safety, such as (but not limited to): 
• Blocked vents
• Loose/missing hardware
• Loose or broken electrical connections
General Maintenance
Poorly maintained equipment can become a safety 
hazard. In order for equipment to operate safely and 
correctly over a long period of time, periodic maintenance 
and occasional repairs are necessary. DO NOT perform 
routine service unless all electrical components are shut 
OFF. 
Regular maintenance will improve performance and 
extend engine/equipment life. Generac Mobile Products, 
LLC recommends all maintenance work be performed by 
a GMP ASD. 
Preparing for Service
Before servicing the unit, follow the instructions below.
1. Verify the main breaker switch and lamp switches 
are OFF.
2. Disconnect shore power from the unit.
3. Disconnected linked units.
4. Attach a “Do Not Start” 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.
Cleaning the Unit
CAUTION
(000325a)
Equipment damage. Never spray water to clean unit.
Do not introduce water into generator widings, 
terminals, or fuel system during the cleaning process.
Doing so will result in equipment damage.
Always clean the unit after each use to remove dust, 
grease, mud, or spilled fuel or oil. 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 the cabinet interior.
This unit contains sensitive electronic components that 
can be damaged by high pressure and heat. 
NOTE: Do not wash with a high pressure hose or power 
washer. Water may enter the cabinet and collect in the 
generator windings or other electrical parts, causing 
damage. 
Inspecting the Unit
•
If the unit is stored outside, check for water inside 
the cabinet 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.
• Verify winch cables are in good condition and 
centered on each pulley. DO NOT use a cable that 
is kinked or starting to unravel.
