DC Operation
The DC receptacle may be used for charging 12 volt automotive-type batteries only.
It is not designed to operate DC motors or transformers. Output voltage is 15-30V.
DC output will vary according to the position of the Smart-throttle switch.
1. Connect the charging cable to the DC receptacle of the generator and then to the
battery terminals.
n Batteries give off explosive gases; keep spark, flames, cigarettes, and other
sources of ignition away.
n Provide adequate ventilation when charging.
n Batteries contains sulfuric acid (electrolyte). Contact with skin or eyes may cause
severe burns. Wear protective clothing and a face shield.
n If contact is made with skin, flush with water immediately.
n If contact is made in eyes, flush with water immediately for at least 15 minutes
and contact a physician.
n Battery contents are poisonous — If swallowed, drink large quantities of water or
milk and follow with milk of magnesia or vegetable oil and call a physician.
n KEEP OUT OF REACH OF CHILDREN.
n Do not start an automobile engine with the generator still connected to the
battery. The generator can be damaged.
n Connect the positive battery terminal to the positive charging cord. Do not
reverse the charging cables, or serious damage to the generator and/or battery
may occur.
n To prevent the possibility of creating a spark near the battery, connect the
charging cable first to the generator then to the battery. After charging,
disconnect the cable first at the battery.
n Before connecting charging cables to a battery that is installed in a vehicle,
disconnect the vehicle’s ground battery cable. Reconnect the vehicle's ground
battery cable after the charging cables are removed. This procedure will prevent
the possibility of a short circuit and sparks if accidental contact is made between
a battery terminal and the vehicle's frame or body.
The DC output is to be used to charge batteries only. Serious damage to the stator
windings can occur if connected to a DC motor or transformer.
n The DC receptacle may be used while the AC power is in use.
n The DC receptacle is protected from an overload with a fuse. If the DC circuit is
overloaded, the 5 amp fuse will blow and power to the DC receptacle will cease.
The red light on the DC panel will illuminate. The fuse is located to the left of the
receptacle and is accessed by snapping open the access door. Replace the fuse
with one of the same capacity. Using a higher rated fuse may cause damage to
the generator alternator.

2. Start the engine
n The DC receptacle may be used while the AC power is in use.
n An overloaded DC circuit will trip the DC circuit fuse. The fuse must be replaced
before the DC receptacle is operative.
n Replace the fuse with one of the same size and rating (5A).
n Exceeding the current rating may lead to alternator damage.
