§ MBU burner well, frame, fuel nipple and power connector, control panel, fuel lines, fuel cap and gasket.
§ Power converter external damage, serviceability of connectors, power cord, and controls.

LUBRICATION SERVICE INTERVALS
There are no lubrication requirements for the MBU and its associated equipment.
Proper cleaning of the MBU and components is an integral part of maintenance. It will help prevent possible
problems in the future, so make it a habit to clean the MBU and its components whenever necessary. The burner
can be cleaned with a rag or brush. The burner well must be kept clean at all times. Use a damp rag for this task.
Also pay particular attention to the air vents on the regulator and float valve assemblies. These should be kept
clean with a brush. Clean all connectors, including those on the power cables with a dry brush. Wipe battery pack
and power converter housing with a damp rag to remove dust and stains
