1.1 Operating Safety
BACKFEED FROM THE GENERATOR INTO THE PUBLIC POWER
DISTRIBUTION SYSTEM CAN CAUSE SERIOUS INJURY OR
DEATH TO UTILITY WORKERS!
Improper connection of generator to a building's electrical system can
allow electrical current from the generator to backfeed into utility lines.
This may result in electrocution of utility workers, fire, or explosion.
Connections to a building's electrical system must be made by a
qualified electrician and comply with all applicable laws and electrical
codes.
If connected to a building's electrical system the generator must meet
the power, voltage, and frequency requirements of the equipment in
the building. Differences in power, voltage, and frequency
requirements may exist and improper connection may lead to
equipment damage, fire, and personal injury or death.
Familiarity and proper training are required for the safe operation of
equipment. Equipment operated improperly or by untrained personnel
can be dangerous. Read the operating instructions contained in both
this manual and the engine manual and familiarize yourself with the
location and proper use of all controls. Inexperienced operators should
receive instruction from someone familiar with the equipment before
being allowed to operate the machine.
1.1.1 NEVER operate the generator when open containers of fuel, paint, or
other flammable liquids are near.
1.1.2 NEVER operate the generator, or tools attached to the generator, with
wet hands.
1.1.3 NEVER use worn electrical cords. Severe electrical shock and
equipment damage may result.
1.1.4 NEVER run the electrical cords under the generator, or over vibrating
or hot parts.
1.1.5 NEVER enclose or cover the generator when it is in use or when it is
hot.
1.1.6 NEVER overload the generator. The total amperage of the tools and
equipment attached to the generator must not exceed the load rating
of the generator.
1.1.7 NEVER operate the machine in snow, rain, or standing water.
1.1.8 NEVER allow untrained personnel to operate or service the generator.
The generator set should be set up by a trained electrician.
1.1.9 NEVER stand on the machine.
1.1.10 DO NOT stand under the machine while it is being hoisted or moved.

3. Operation
3.1 Information Regarding Operation
The information regarding the operation of the machine included in this
manual is condensed. Refer to the Operator’s Manual for complete
operating instructions. Always read, understand, and follow the
procedures in the Operator’s Manual when operating the machine.
3.2 Determining Power Requirements
This generator is designed to operate single-phase, 60 Hz appliances
running at 120 VAC or 240 VAC. Check the nameplate or label
provided on tools and appliances to make sure their power
requirements match the power output of the generator.
Some appliances and tools require a surge of current when starting.
This means that the amount of power needed to initially start the
equipment is larger than the power required to keep it running. The
generator must be capable of supplying this “surge” current. Other
types of appliances require more power than is actually stated on their
nameplate.
The information in “Approximate Starting Power Requirements” is
offered only as a general guideline to help you in determining power
requirements for different types of equipment. Check with your nearest
Wacker Dealer, or contact the manufacturer or dealer of the tool or
appliance, with questions regarding its power requirements.
CAUTION: If a tool or appliance does not reach full speed within a few
seconds when switched on, turn it off immediately to avoid damage.
Approximate Starting Power Requirements:
• Incandescent lights and appliances such as irons and hot plates, which
use a resistive-type heating element, require the same wattage to start
and run as is stated on their nameplates.
• Fluorescent and mercury lamps require 1.2–2 times their stated
wattage to start.
• Electrical motors and many types of electrical tools often require a
large starting current. The amount of starting current depends on the
type of motor and its use.
• Most electrical tools require 1.2–3 times their stated wattage for
starting.
• Loads such as submersible pumps and air compressors require a very
large force to start. They need as much as 3–5 times the wattage
stated on the nameplate in order to start.

If the wattage is not given for a particular tool or appliance, it can be
calculated by multiplying its voltage and amperage requirements:
Single Phase: VOLTS x AMPS = WATTS
Three Phase: VOLTS x AMPS x 1.732 x 0.8 = WATTS
