Operation
Step 4: Connecting Electrical Loads
Using Extension Cords
Use only grounded extension cords marked for outdoor
use rated for your loads. Follow cord safety instructions.
WARNING!
Damaged or overloaded extension
cords could overheat, arc, and burn resulting in
death or serious injury.
NOTICE
For generator output required see
Generator
Capacity.
Connect electrical loads in off position then turn
on for operation.
230 Volt AC, 15 Amp Receptacles
Use receptacles to operate 230 Volt AC, single–phase,
50 Hz electrical loads requiring up to 2,500 watts (2.5 kW)
at 10.9 Amps of current. Use cord sets that are rated for
230 Volt AC loads at 15 Amps (or greater).
Generator Capacity
To make sure your generator can supply enough running
watts and starting watts for the items you will power at the
same time, follow these simple steps:
1. Select the items you will power at the same time. See
following list for typical wattages.
* Typical wattages listed are approximate only. Check tool
or appliance for actual wattage.
** Per Briggs & Stratton 628K, Starting Watts represents
the momentary electrical current the generator can
provide to start electric motors. Starting Watts does
not represent the power required to continuously run
electrical loads. Starting Watts is the maximum current
that can momentarily be supplied when starting a motor,
multiplied by the generator’s rated voltage.
2. Total the running watts. This is the amount of power
your generator must produce to keep your items
running. See following example:
Example
Total running watts
= 2355
Highest Starting Watts
= 2000
Total generator watts required
= 4355
3. Estimate the Starting Watts you will need. Because
not all motors start at the same time, total Starting
Watts can be estimated by adding only the item with
the highest additional Starting Watts requirements to
the total running watts from step 2.
Power Management
To manage generator power, sequentially add loads as
follows:
1. With nothing connected to generator, start the engine
outdoors.
2. Plug in and turn on the first load, preferably the largest
load you have.
3. Permit the generator output to stabilize (engine runs
smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeat steps 4 and 5 for each additional load.
Never add more loads than the generator capacity. Take
special care to consider surge loads in generator capacity.
Step 5: Generator Shutdown
1. Turn off and unplug all electrical loads from generator
panel receptacles. Never stop engine with electrical
devices plugged in and turned on.
2. Let engine run at no-load for one minute to stabilize
internal temperatures of engine and generator.
3. Push engine switch to OFF (0) position.
4. Move fuel valve to OFF (0) position.
