• Below is a simplified three-phase three-wire formula
to seek voltage drop or cross-sectional area of
the cable from cable length and working current.
Select such a cable length and thickness so that the
voltage drop will remain less than 5%.

D

Selecting Cable

• Select a cable (F) with sufficient diameter by
considering the permissible current on the cable
and the distance from the generator to the load (G).

• If the current flowing to the load exceeds the
permissible current of the cable, resultant
overheating may burn the cable. Similarly, if the
cable is too small in thickness to the length, the
input voltage to the load will fall to cause the load
input power to drop, as a result, the performance of
the machine cannot be displayed.

hours, even after this product has shut off.

• ALWAYS place this product downwind and point the
engine exhaust away from occupied spaces.

If you start to feel sick, dizzy, or weak while using this
product, get to fresh air RIGHT AWAY. See a doctor.
You may have carbon monoxide poisoning.

Oil Recommendations

Engine Oil

We recommend the use of CJ-4 class engine oil or
superior class for best performance. Using poor quality
engine oil may shorten the life of the engine.

Outdoor temperatures determine the proper oil viscosity
for the engine.

Use the chart to select the best viscosity for the outdoor
temperature range expected.

NOTICE When two or more different brands of oil are
mixed, its performance can be deteriorated. When it
is expected to be used for a long period at light load
(less than 20% load), it’s better to replace the oil with
suitable oil.

under this condition. ***

• Both lamps will turn off when regeneration is
completed. Engine speed will return to normal
operation (1,800 rpm).

CAUTION Do not stop engine during enforced
regeneration operation, except for unavoidable
conditions.

• If it is necessary to use a load during manual
regeneration, push the Regeneration switch (D)
again to interrupt the regeneration operation and
then turn on the breaker.

• If the unit is continuously operated without manual
regeneration started, even while the Regeneration
Required lamp is lit, the DPF error lamp (E) will
eventually turn on to stop the engine.

• If the engine stops, restart it and push the
Regeneration switch to start manual regeneration.
Unless it is pressed, the engine will stop one
minute after it starts.

** If the breaker is left on, the unit will not switch

to manual regeneration. Further, if the breaker

Periodic Load Operation

Not for

Reproduction

When a diesel engine driven generator is continuously
operated with less light load than 30% or at no load
for a long time, carbon will be stuck inside the exhaust
pipe, exhaust muffler and engine. Unburned fuel
will also leak sometimes from the turbo wastegate,
connected portion of exhaust pipe, and the outlet
port of muffler. If it is continuously operated under the
conditions, the unburned fuel could ignite.

Moreover, carbon accumulation could cause engine
power drop or overheating, resulting in engine
damage.

Eliminate carbon accumulation by periodically burning
it during operation with a load until the exhaust gas
becomes almost clear.

(For load current, refer to the following table as a
standard value.)

WARNING

Increase the load factor, step by step, paying attention
to the exhaust conditions. Also watch for sparks from
the exhaust pipe that could result in a fire.

Excessive loads and/or underinflation cause tire overloading and, as a result, abnormal tire flexing occurs. This situation
can generate an excessive amount of heat within the tire. Excessive heat may lead to tire failure. It is the air pressure that
enables a tire to support the load, so proper inflation is critical. The proper air pressure may be found on the
certification/VIN label and/or on the Tire Placard. This value should never exceed the maximum cold inflation pressure
stamped on the tire.

1.2. STEPS FOR DETERMINING CORRECT LOAD LIMIT – TOW VEHICLE

1. Locate the statement, “The combined weight of occupants and cargo should never exceed XXX lbs.,” on
your vehicle’s placard.

2. Determine the combined weight of the driver and passengers who will be riding in your vehicle.

3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds.

4. The resulting figure equals the available amount of cargo and luggage capacity. For example, if the “XXX”
amount equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available
cargo and luggage capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.).

5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may n ot
safely exceed the available cargo and luggage capacity calculated in Step # 4.

6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult the
tow vehicle’s manual to determine how this weight transfer reduces the available c argo and luggage
capacity of your vehicle.

1.4. TIRE SAFETY - EVERYTHING RIDES ON IT

The National Traffic Safety Administration (NHTSA) has published a brochure (DOT HS 809 361) that
discusses all aspects of Tire Safety, as required by CFR 575.6. This brochure is reproduced in part below. It
can be obtained and downloaded from NHTSA, free of charge, from the following web site:

http://www.nhtsa.dot.gov/cars/rules/TireSafety/ridesonit/tires_index.html

Studies of tire safety show that maintaining proper tire pressure, observing tire and vehicle load limits (not
carrying more weight in your vehicle than your tires or vehicle can safely handle), avoiding road hazards, and
inspecting tires for cuts, slashes, and other irregularities are the most important things you can do to avoid tire
failure, such as tread separation or blowout and flat tires. These actions, along with other care and
maintenance activities, can also:

Improve vehicle handling
Help protect you and others from avoidable breakdowns and accidents
Improve fuel economy
Increase the life of your tires.

Use this information to make tire safety a regular part of your vehicle maintenance routine. Recognize that the
time you spend is minimal compared with the inconvenience and safety consequences of a flat tire or other tire
failure.

1.5. SAFETY FIRST–BASI C TIRE MAINTENANCE

Properly maintained tires improve the steering, stopping, traction, and load-carrying capability of your vehicle.
Underinflated tires and overloaded vehicles are a major cause of tire failure. Therefore, as mentioned above,
to avoid flat tires and other types of tire failure, you should maintain proper tire pressure, observe tire and
vehicle load limits, avoid road hazards, and regularly inspect your tires.

1.5.1. F

Tire information placards and vehicle certification labels contain information on tires and load limits. These
labels indicate the vehicle manufacturer's information including:

Recommended tire size
Recommended tire inflation pressure
Vehicle capacity weight (VCW–the maximum occupant and cargo weight a vehicle is designed to carry)
Front and rear gross axle weight ratings (GAWR– the maximum weight the axle systems are designed to

Both placards and certification labels are permanently attached to the trailer near the left front.

1.5.2. U

Tire inflation pressure is the level of air in the tire that provides it with load-carrying capacity and affects the
overall performance of the vehicle. The tire inflation pressure is a num ber that indicates the amount of air
pressure– measured in pounds per square inch (psi)–a tire requires to be properly inflated. (You will also find
this number on the vehicle information placard expressed in kilopascals (kpa), which is the metric measure
used internationally.)

Manufacturers of passenger vehicles and light trucks determine this number based on the vehicle's design
load limit, that is, the greatest amount of weight a vehicle can safely carry and the vehicle's tire size. The
proper tire pressure for your vehicle is referred to as the "recommended cold inflation pressure." (As you will
read below, it is difficult to obtain the recommended tire pressure if your tires are n ot cold.)
Because tires are designed to be used on more than one type of vehicle, tire manufacturers list the "maximum
permissible inflation pressure" on the tire sidewall. This number is the greatest amount of air pressure that
should ever be put in the tire under normal driving conditions.

INDING YOUR VEHICLE'S RECOMMENDED TIRE PRESSURE AND LOAD LIMITS

carry).

NDERSTANDING TIRE PRESSURE AND LOAD LIMITS

1.5.3. C

It is important to check your vehicle's tire pressure at least once a month for the following reasons:

For convenience, purchase a tire pressure gauge to keep in your vehicle. Gauges can be purchased at tire
dealerships, auto supply stores, and other retail outlets.
The recommended tire inflation pressure that vehicle manufacturers provide reflects the proper psi when a tire
is cold. The term cold does not relate to the outside temperature. Rather, a cold tire is one that has not been
driven on for at least three hours. When you drive, your tires get warmer, causing the air pressure within them
to increase. Therefore, to get an accurate tire pressure reading, you must measure tire pressure when the tires
are cold or compensate for the extra pressure in warm tires.

49

HECKING TIRE PRESSURE

Most tires may naturally lose air over time.
Tires can lose air suddenly if you drive over a pothole or other object or if you strike the curb when

parking.

With radial tires, it is usually not possible to determine underinflation by visual inspection.

1.5.4. STEPS FOR MAINTAINING PROPER TIRE PRESSURE

Not for

Reproduction

Step 1: Locate the recommended tire pressure on the vehicle's tire information placard, certification

label, or in the owner's manual.
Step 2: Record the tire pressure of all tires.
Step 3: If the tire pressure is too high in any of the tires, slowly release air by gently pressing on the

tire valve stem with the edge of your tire gauge until you get to the correct pressure.
Step 4: If the tire pressure is too low, note the difference between the measured tire pressure and the

correct tire pressure. These "missing" pounds of pressure are what you will need to add.
Step 5: At a service station, add the missing pounds of air pressure to each tire that is underinflated.
Step 6: Check all the tires to make sure they have the same air pressure (except in cases in which the

front and rear tires are supposed to have different amounts of pressure).

If you have been driving your vehicle and think that a tire is underinflated, fill it to the recommended cold
inflation pressure indicated on your vehicle's tire information placard or certification label. While your tire may
still be slightly underinflated due to the extra pounds of pressure in the warm tire, it is safer to drive with air
pressure that is slightly lower than the vehicle manufacturer's recommended cold inflation pressure than to
drive with a significantly underinflated tire. Since this is a temporary fix, don't forget to recheck and adjust the
tire's pressure when you can obtain a cold reading.

1.5.5. T

To maintain tire safety, purchase new tires that are the same size as the vehicle's original tires or another size
recommended by the manufacturer. Look at the tire information placard, the owner's manual, or the sidewall of
the tire you are replacing to find this information. If you have any doubt about the correct size to choose,
consult with the tire dealer.

1.5.6. T

The tire tread provides the gripping action and traction that prevent your vehicle from slipping or sliding,
especially when the road is wet or icy. In general, tires are not safe and should be replaced when the tread is
worn down to 1/16 of an inch. Tires have built-in treadwear indicators that let you know when it is time to
replace your tires. These indicators are raised sections spaced intermittently in the bottom of the tread
grooves. When they appear "even" with the outside of the tread, it is time to replace your tires. Another method
for checking tread depth is to place a penny in the tread with Lincoln's head upside down and facing you. If
you can see the top of Lincoln's head, you are ready for new tires.

1.5.7. T

To avoid vibration or shaking of the vehicle when a tire rotates, the tire must be properly balanced. This
balance is achieved by positioning weights on the wheel to counterbalance heavy spots on the wheel-and-tire
assembly. A wheel alignment adjusts the angles of the wheels so that they are positioned correctly relative to
the vehicle's frame. This adjustment maximizes the life of your tires. These adjustments require special
equipment and should be performed by a qualified technician.

1.5.8. T

The proper repair of a punctured tire requires a plug for the hole and a patch for the area inside the tire that
surrounds the puncture hole. Punctures through the tread can be repaired if they are not too large, but
punctures to the sidewall should not be repaired. Tires must be removed from the rim to be properly inspected
before being plugged and patched.

Not for

Reproduction

Please r efer to the diagram below .

P

The "P" indicates the tire is for passenger vehicles.

Next number

This three-digit number gives the width in millimeters of the tire from sidewall edge to sidewall edge. In
general, the larger the number, the wider the tire.

Next number

This two-digit number, known as the aspect ratio, gives the tire's ratio of height to width. Numbers of 70 or
lower indicate a short sidewall for improved steering response and better overall handling on dry pavement.

R
The "R" stands for radial. Radial ply construction of tires has been the industry standard for the p ast 20 years.

Next number

This two-digit number is the wheel or rim diameter in inches. If you change your wheel size, you will have to
purchase new tires to match the new wheel diameter.

Next number

This two- or three-digit number is the tire's load index. It is a measurement of how much weight each tire can
support. You may find this information in your owner's manual. If not, contact a local tire dealer. Note: You may
not find this information on all tires because it is not required by law.

M+S

The "M+S" or "M/S" indicates that the tire has some mud and snow capability. Most radial tires have these
markings; hence, they have some mud and snow capability.

Speed Rating

The speed rating denotes the speed at which a tire is designed to be driven for extended periods of time. The
ratings range from 99 miles per hour (mph) to 186 mph. These ratings are listed below. Note: You may not find
this information on all tires because it is not required by law.

* For tires with a maximum speed capability over 149 mph, tire manufacturers sometimes use the letters ZR.
For those with a maximum speed capability over 186 mph, tire manufacturers always use the letters ZR.

U.S. DOT Tire Identification Number

This begins with the letters "DOT" and indicates that the tire meets all federal standards. The next two
numbers or letters are the plant code where it was manufactured, and the last four numbers represent the
week and year the tire was built. For example, the numbers 3197 means the 31st week of 1997. The other
numbers are marketing codes used at the manufacturer's discretion. This information is used to contact
consumers if a tire defect requires a recal l.

Tire Ply Composition and Materials Used

The number of plies indicates the number of layers of rubber-coated fabric in the tire. In general, the greater
the number of plies, the more weight a tire can support. Tire manufacturers also must indicate the materials in
the tire, which include steel, nylon, polyester, and others.

Maximum Load Rating

This number indicates the maximum load in kilograms and pounds that can be carried by the tire.

Maximum Permissible Inflation Pressure

This number is the greatest amount of air pressure that should ever be put in the tire under normal driving
conditions.

1.5.9.2. UTQGS Information

Treadwear Number

This number indicates the tire's wear rate. The higher the treadwear number is, the longer it should take for the
tread to wear down. For example, a tire graded 400 should last twice as long as a tire graded 200.

Traction Letter

This letter indicates a tire's ability to stop on wet pavement. A higher graded tire should allow you to stop your
car on wet roads in a shorter distance than a tire with a lower grade. Traction is graded from highest to lowest
as "AA","A", "B", and "C".

Temperature Letter

This letter indicates a tire's resistance to heat. The temperature grade is for a tire that is inflated properly and
not overloaded. Excessi ve speed, underinflation or excessive loading, either separately or in combination, can
cause heat build-up and possible tire failure. From highest to lowest, a tire's resistance to heat is graded as
"A", "B", or "C".

1.5.9.3. Additional Information on Light Truck Tires

Not for

Reproduction

Please refer to the following diagram.

Tires for light trucks have other markings besides those found on the sidewalls of passenger tires.

LT

The "LT" indicates the tire is for light trucks or trailers.

ST

An "ST" is an indication the tire is for trailer use only.

Max. Load Dual kg (lbs) at kPa (psi) Cold

This information indicates the maximum load and tire pressure when the tire is used as a dual, that is,
when four tires are put on each rear axle (a total of six or more tires on the vehicle).

Max. Load Single kg (lbs) at kPa (psi) Cold

This information indicates the maximum load and tire pressure when the tire is used as a single.

Load Range

This information identifies the tire's load-carrying capabilities and its inflation limits.

1.6. TIRE SAFETY TIPS

Preventing Tire Damage

Slow down if you have to go over a pothole or other object in the road.
Do not run over curbs or other foreign objects in the roadway, and try not to strike the curb when

parking.

Tire Safety Checklist

Check tire pressure regularly (at least once a month), including the spare.
Inspect tires for uneven wear patterns on the tread, cracks, foreign objects, or other signs of wear or

trauma.
Remove bits of glass and foreign objects wedged in the tread.
Make sure your tire valves have valve caps.
Check tire pressure before going on a long trip.
Do not overload your vehicle. Check the Tire Information and Loading Placard or User’s Manual for the

maximum recommended load for the vehicle.
