2.1GENERATOR CONTROL PANEL
The following features are mounted on the generator control panel (Figure 2.1):
◆2.1.1 FUEL PRIMER
Before starting a cold engine (if it has not been start- ed in more than two weeks), you must press this switch for approximately ten seconds to bring fuel from the tank to the fuel pump. This rocker type switch springs back into its original position when you release it.

◆2.1.4 LINE BREAKERS
Protects generator’s AC output circiut against overload, i.e., prevents unit from exceeding wattage/amperage capacity. This unit has two
