is provided with the following:
If this condition (low oil pressure) should occur, please refer
to the engine troubleshooting table in this manual.
Welder Protection System
In the event of an overload, this welder/generator is equipped
with a welder protection system. If an overload is detected
while operating the welder/generator, the welder protection
system will shut down the engine.
Open Delta Excitation System
The SDW-225SS generator is equipped with the state of the
art "
Open-Delta
consist of an electrically independent winding wound among
stationary windings of the AC output section.
There are four connections of the open delta A, B, C and D.
During steady state loads, the power from the voltage
regulator is supplied from the parallel connections of A to B,
A to D, and C to D. These three phases of the voltage input
to the voltage regulator are then rectified and are the
excitation current for the exciter section.
When a heavy load, such as a motor starting or a short
circuit occurs, the automatic voltage regulator (AVR)
switches the configuration of the open delta to the series
connection of B to C. This has the effect of adding the
voltages of each phase to provide higher excitation to the
exciter section and thus better voltage response during the
application of heavy loads.
The connections of the AVR to the AC output windings are
for sensing only. No power is required from these windings.
The open-delta design provides virtually unlimited excitation
current, offering maximum motor starting capabilities. The
excitation does not have a "

The SDW-225SS is powered by a 4-cycle KUBOTA
engine. This engine is designed to meet every performance
requirement for generator. Refer to Table 1 for engine
specifications.

Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence (see Figure 5). DO NOT
torque the wheel lug nuts all the way down. Tighten each
lug nut in 3 separate passes as defined by Table 5.
3. After first road use, re-torque all lug nuts in sequence.
Check all wheel lug nuts periodically.

Towing Safety Precautions
CAUTIONCAUTION
CAUTION
CAUTIONCAUTION
Check with your local county or state towing safety
regulations before towing your generator.
To reduce the possibility of an accident while transporting
the generator on public roads, always make sure the trailer
(Figure 7) that supports the generator and the towing vehicle
are in good operating condition and both units are
mechanically sound.
The following list of suggestions should be used when towing
your generator:
■
Make sure the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating" (GVWR).
■
ALWAYS inspect the hitch and coupling for wear. NEVER
tow a trailer with defective hitches, couplings, chains
etc.
■
Check the tire air pressure on both towing vehicle and
trailer. Also check the tire tread wear on both vehicles.
■
ALWAYS make sure the trailer is equipped with a "Safety
Chain".
■
ALWAYS attach trailer’s safety chain to bumper of towing
vehicle.
■
ALWAYS make sure the vehicle and trailer directional,
backup, brake, and trailer lights are connected and
working properly.
■

SDW-225SS — INSTALLATION
Outdoor Installation
Install the generator in a location where it will not be exposed
to rain or sunshine. Make sure that the welder/generator is
on secure level ground so that it cannot slide or shift around.
Also install the generator in a manner so that the exhaust
will not be discharged in the direction of nearby homes.
The installation site must be relatively free from moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and grounding.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear, not
only to the engine parts, but also to the alternator parts.
CAUTICAUTI
CAUTION
CAUTICAUTI
Pay close attention to ventilation when operating the
generator inside tunnels and caves. The engine exhaust
contains noxious elements.
Indoor Installation
Exhaust gases from diesel engines are extremely poisonous.
Whenever an engine is installed indoors the exhaust fumes
must be vented to the outside.
The engine should be installed at least two feet from any
outside wall. Using an exhaust pipe which is too long or too
small can cause excessive back pressure which will cause
the engine to heat excessively and possibly burn the valves.
Eliminate the danger of deadly carbon monoxide gas.
Remember that exhaust fumes from any diesel engine are
very poisonous if discharged in a closed room, but harmless
if allowed to mix with the outside air. If the generator is
installed indoors, you must make provisions for venting the
engine exhaust to the outside of the building.
An electric shock is apt to happen when generators are
used. Pay close attention to handling when operating
generator and always use rubber boots and gloves to
insulate the body from a short circuit.
Connecting the Ground
The generator ground lug and the GFCI ground terminal should
always be used to connect the generator to a suitable ground.
The ground cable should be #8 size wire minimum. See Figure 15.

pole, 20 amp breaker is provided for the G.F.C.I. receptacle.
Make sure to switch both circuit breakers to the "OFF"
position prior to starting the engine.
a 2-pole, 25
Extension Cable
When electric power is to be provided to various tools or
loads at some distance from the generator, extension cords
are normally used. Cables should be sized to allow for
distance in length and amperage so that the voltage drop
between the generator and point of use (load) is held to a
minimum. Use the cable selection chart (Table 6) as a guide
for selecting proper cable size.

Lubrication Oil
Fill the engine crankcase with lubricating oil through the filler
hole, but do not overfill. Make sure the generator is level.
With the dipstick inserted all the way, but without being
screwED into the filler hole, verify that the oil level is
maintained between the two notches (Figure 16) on the
dipstick. See Table 3 for proper selection of engine oil.
Fuel
Fill the fuel tank with clean and fresh diesel fuel. Do not fill
the tank beyond capacity.
Pay attention to the fuel tank capacity when replenishing
fuel. Refer to the fuel tank capacity listed on page 11
Specification Table 1.
The fuel tank cap must be closed tightly after fillin
fuel in a safety container. If the container does not have a
spout, use a funnel.
Never fill the fuel tank while the engine is running or in
the dark. Diesel fuel spillage on a hot engine can cause
a fire or explosion. If diesel fuel spillage occurs, wipe
up the spilled diesel fuel completely to prevent fire
hazards.

Battery
This unit is of negative ground. DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. Battery life will be shortened, if the fluid level is not
properly maintained. Add only distilled water when
replenishment is necessary.
The battery is sufficiently charged if the specific gravity of
the battery fluid is 1.28 (at 68° F). If the specific gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunctions, always
keep the terminals firmly tightened. Coating the terminals
with a thin film of grease will help to inhibit corrosion.
The battery gradually deteriorates over time. The actual life
span will vary according to operating conditions, but generally
a battery two years or older should be replaced.

dle Control Switch
The generator is provided with an automatic idle control device
for noise suppression and reduced fuel consumption. The
automatic idle control automatically engages under a no-load
condition. With the automatic idle control switched to "ON", the
engine revolutions will automatically drop to about 2600 rpm
(low-speed operation) within 3 seconds after the load stops.
When the operation is resumed, the engine speed is automatically
increased to about 3600 rpm (high speed operation) as soon as
the load is connected.
Fuel Gauge
The fuel gauge is located on top of the generator's enclosure
and allows easy monitoring of the fuel level.
GFCI Receptacle
Before connecting a load to the generator's GFCI receptacle,
push
the "Test Button" on the front of receptacle before
connecting the load, to confirm that the receptacle is
functioning correctly.
