OPERATING YOUR GENERATOR

Before using a generator, a ground wire must be connected to the ground terminal. The Ground terminal is located on the Front Panel. Before using the ground terminal consult a qualified electrician.

Disconnect all devices from the generator.
Open the fuel valve by turning the fuel valve knob from "off" to "on". Make sure the valve is turned all the way, to ensure that the valve has been fully opened for fuel to pass through.
Turn choke to "closed" or OFF position. Leave the choke in the "Open" position if the generator is still warm from recent use, or if the air temperature is higher than 50°F (10°C).
Locate and press primer bulb 15-20 times to move fuel through the lines and into the engine.
Note: This step is only necessary when the engine is cold
1. (HY2800 Electric only, for HY2000 and manual start proceed to 5b) Turn Power switch to "Start" for 5 seconds to start engine. If the engine does not start, the battery may be dead, proceed to step 5b to start the engine. Running the engine charges the battery.
2. Pull Recoil handle until engine starts. Several pulls may be required until engine starts. Do not release the pull cord at the end of a pull, this will damage the recoil assembly. Bring the pull handle back down to the unit by hand.
Once the generator has started, wait at least 30 seconds for it to warm up, and then you may slowly open the choke lever until it is fully open, or OFF.
Connect all of your devices to the generator.
Turn EcoMode switch to "On". This will reduce the output to a level where the generator will only produce enough power for the connected devices. The reduction of extra, unused power saves fuel.

Connections for standby power to a building’s electrical system must be done by a qualified electrician and must comply with all applicable laws and electrical codes. Improper connections may cause serious injuries to electrical worker during power outages. Additionally, the generator may explode or cause fires when the utility power is restored.
