6. CAPACITY OF GENERATOR

6-1. Selection of Proper Generator

Select the proper generator as follows according to the power consumption, output and the like of the AC

electrical equipment to be used.

(1) When the power consumption of the electrical equipment is known

When the power consumption of the electrical equipment is known, calculate the necessary output of the

generator (VA) according to the formula shown in the table below. When the sum of the calculated "necessary

output of the generator (VA)" is equal to or less than the rated AC output of the generator, the generator can

be used continuously.

Electric power tools

(Commutator motors)

Bulbs, electric heaters, etc.

(Induction motors)

0.8 to 0.95

0.4 to 0.75

Necessary output of the generator (VA)

Power consumption of the

electrical equipment (W)

Power factor

--- 3 ---

Power consumption of an electric circular saw, planer, disk grinder or the like may be higher depending on the

load. In order to deliver the full performance, it is necessary to estimate 1.5 to 2 times greater power

consumption.

(2) When the motor output of the electrical equipment is known

Some electrical equipment is not indicated with the current and the power consumption but the motor output.

In such cases, the generator can be used when the sum of the "necessary output of the generator (VA)"

obtained from the following formula is less than the rated AC output of the generator (VA).

Because a general electrical equipment is not indicated with the power factor, "0.8" is used in the case of an

electric power tool and "0.5" in the case of a general-purpose motor for the above rough calculation.

Generally, the following values are used though efficiency varies depending on the types of motors.

6-2. Starting Current

The current required from starting the above electrical equipment to operating in steady state is larger than the

current or the power required during "operation" of the electrical equipment. This is called "starting current".

There is no problem if no load is applied to an electric power tool equipped with a commutator motor from the

start. However, there may be a case that an electric power tool equipped with an induction motor (especially the

starting current of a split-phase induction motor is about three times larger than the current during operation)

cannot be started.

7. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Models E 43, E 60 and E 71 Generators by all

of our customers, it is very important that at the time of sale the salesperson carefully ensures that the buyer

seriously recognizes the importance of the contents of the Handling Instructions, and fully understands the

meaning of the precautions listed on the Caution Plates attached to each unit.

7-1. Handling Instructions

Although every effort is made in each step of design, manufacture and inspection to provide protection against

safety hazards, the dangers inherent in the use of any generator cannot be completely eliminated. Accordingly,

specific precautions and suggestions for the use of the generator are listed in the Handling Instructions to

enhance the safe and efficient use of the tool by the customer. Salesperson must be thoroughly familiar with the

contents of the Handling Instructions to be able to offer appropriate guidance to the customer during sales

promotion.

7-2. Thorough Instruction to the Customers

(1) HITACHI electronic controlled products should not be used with portable generators.

Irregular generator power could cause these products to fail. Regarding other manufacturer's products, please

contact the manufacturer to see if it is safe to use the electronic controlled products with portable generators.

(3) Each generator has AC receptacles as shown in the table below.

(2) There is no oil in the engine crankcase when the generator is shipped. You must add oil before starting the

engine. Check the oil level before each use with the generator on a level surface and the engine stopped.

Engine oil is a major factor affecting engine performance and

service life. Non-detergent and 2-stroke oils will damage the engine

and are not recommended. Use 4-stroke motor oil that meets or

exceeds the requirements for API service classification SJ or SL.

Always check the API SERVICE label on the oil container to be sure

it includes the letters SJ or SL. SAE 10W-30 is recommended for

general, all-temperature use. Other viscosities shown in the right

graph may be used when the average temperature in your area is

within the indicated range.

Note that each of the above current values means the maximum current for one receptacle.

(4) When using an extension cord between the generator and an electrical equipment, it is necessary to observe

the specifications about the cord thickness (nominal cross sectional area of the core) and the length indicated

on the electrical equipment. If a long and thin extension cord is used, the voltage will be reduced remarkably

and the electrical equipment will be overheated or put out of action. To minimize voltage reduction, it is

necessary to use a short extension cord whose core is as thick as possible.

(5) Before operation, perform inspection according to the Handling Instructions.

8. MAINTENANCE

Periodical maintenance is required for efficient use of the Models E 43, E 60 and E 71 by the customers. Advise

the customers to thoroughly read and understand the maintenance instructions specified in the Handling

Instructions ("MAINTENANCE").
