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.
