Add up rated watts of all lights, tool, appliance and motor
loads you are powering at one time. This total should
NOT be greater than (a) generator’s rated wattage
capacity, or (b) circuit breaker rating of the receptacle
supplying power. See “Don’t Overload the Generator” on
Page 8.

	STOPPING THE ENGINE
•	Disconnect all electrical loads
•	Run engine at no-load for about five minutes,
• Turn off the engine by moving the On/Off Switch to the
	“OFF” position. See engine manual.		• Connect battery charge cable clamp with red handle

	CHARGING A BATTERY		“Stopping the Engine” on Page 7).
			NOTE: Use an automotive hydrometer to test battery
Your generator has the capability of recharging a dis-			state of charge and condition. Follow the hydrometer
charged 12-volt automotive or utility style storage			manufacturer’s instructions carefully. Generally, a bat-
battery. Do not use the unit to charge any 6-volt batter-			tery is considered to be at 100% state of charge when
