8. PRECAUTIONS IN SALES PROMOTION

8-1. Safety Instructions

In the interest of promoting the safest and most efficient use of the Models DS 12DVF3 and DS 9DVF3 Cordless

Driver Drills 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 Plate and Name Plate attached to each tool.

A. Handling Instructions

Salespersons must be thoroughly familiar with the contents of the Handling Instructions in order to give pertinent

advice to the customer. In particular, they must have a thorough understanding of the precautions for use of the

cordless tools which are different from those of ordinary electric power tools.

(1) Before use, ensure that the unit is fully charged.

New units are not fully charged. Even if the units were fully charged at the factory, long periods of inactivity,

such as during shipping, cause the storage battery to lose its charge. Customers must be instructed to fully

charge the unit prior to use.

(2) When charging storage batteries, use only the exclusive Model UC 18YG Charger provided with the tool.

Because of the designed rapid-charging feature (about 30 minutes), use of other battery chargers is

hazardous.

(3) Connect the Charger to an AC power outlet only.

Use of any other power source (DC outlet, fuel powered generator, etc.) will cause the Charger to overheat

and burn out.

(4) Do not use any voltage increasing equipment (transformer etc.) between the power source and the Charger.

If the Charger is used with voltage higher than that indicated on the unit, it will not function properly.

(5) Conduct battery charging at an ambient temperature range of 10 ûC --- 40 ûC (50 ûF --- 104 ûF).

Special temperature sensitive devices are employed in the Charger to permit rapid charging. Ensure that

customers are instructed to use the Charger at the indicated ambient temperature range. At temperature

under 10 ûC (50 ûF) the thermostat will not function properly, and the storage battery may be overcharged.

At temperature over 40 ûC (104 ûF), the storage battery cannot be sufficiently charged. The optimum

temperature range is 20 ûC --- 25 ûC (68 ûF --- 77 ûF).

(6) The battery charger should not be used continuously.

At high ambient temperature, if over three storage batteries are charged in succession, the temperature of the

coils on the transformer will rise and there is a chance that the temperature fuse inserted in the interior of the

transformer will inadvertently melt. After charging one battery, please wait about 15 minutes before charging

the next battery.

--- 11 ---

(7) Do not insert foreign objects into the air vents on the Charger

The Charger case is equipped with air vents to protect the internal electronic components from overheating.

Caution the customer not to allow foreign materials, such as metallic or flammable objects, to be dropped or

inserted into the air vents. This could cause electrical shock, fire, or other serious hazards.

(8) Do not attempt to disassemble the Storage Battery or the Charger.

Special devices, such as a thermostat, are built into the storage battery and charger to permit rapid charging.

Incorrect parts replacement and/or wiring will cause malfunctions which could result in fire or other hazards.

Instruct the customer to bring these units to an authorized service center in the event repair or replacement is

necessary.

(9) Disposal of the Storage Batteries (Types EB 1214S and EB 914S)

Ensure that all customers understand that Types EB 1214S and EB 914S Storage Batteries should be

returned to the Hitachi power tool sales outlet or the authorized service center when they are no longer

capable of being recharged or repaired. If thrown into a fire, the batteries may explode, or, if discarded

indiscriminately, leakage of the cadmium compound contained in the battery may cause environmental

pollution.

B. Caution Plate

8-2. Inherent Drawbacks of Cordless Driver Drills Requiring Particular Attention During Sales Promotion

The cordless driver drill offers many advantages; it can be used in places where no power source is available, the

absence of a cord allows easy use, etc. However, any cordless tool has certain inherent drawbacks.

Salespersons must be thoroughly familiar with these drawbacks in order to properly advise the customer in the

most efficient use of the tool.

A. Suggestions and precautions for the efficient use of the tool

(1) Use the Cordless Driver Drill for comparatively light work.

Because they are battery driven, the output of the motor in cordless driver drills is rather low in comparison

with conventional electric power tools. Accordingly, they are not suitable for continuous drilling of many holes

in succession, or for drilling into particularly hard materials which creates a heavy load. Salespersons should

recommend conventional electric power tools for such heavy work.

(2) Drilling of large diameter holes should be conducted at low speed.

Instruct the customer that drilling of large diameter holes or other work which requires particularly strong

torque should be done at low speed. Because there is less torque at high speed, attempting such work at high

speed will not improve working efficiency.

(3) Do not insert a foreign object into body vent holes.

The body of this tool has vent holes for improving the cooling efficiency. As a fan is built into the motor, a

foreign object inserted through a vent hole may cause a failure. Please instruct customers to never insert a

foreign object into the vent hole.

(4) Avoid "Locking" of the motor.

Locking of the motor will cause an overload current that could result in burning of the motor and/or rapid

deterioration of the battery. Salespersons should advise the customer to immediately release the switch and

stop operation if the motor becomes locked. (A jammed drill bit can be disengaged from the workpiece

material by setting the switch to reverse rotation, or by manually turning the main body of the tool.)

(5) Variation in amount of work possible per charge

Although the nominal chargeable capacity of the storage batteries used with the Models DS 12DVF3 and

DS 9DVF3 are 1.4 Ah, the actual capacity may vary within 10% of that value depending on the ambient

temperature during use and charging, and the number of times the batteries have been recharged. It should

be noted that other factors which may have a bearing on the amount of work possible per charge are the

working conditions (ambient temperature, type and moisture content of the workpiece, sharpness of the drill

bit, etc.) and the operational skill of the user.

(6) Precautions in the use of HSS Drill Bits

For example, although the Model DS 12DVF3 is designed for drilling capacities of 25 mm (1") in wood, and

15 mm (19/32") in aluminum, and 12 mm (15/32") in mild steel, this capability is not as efficient as

conventional electric power tools. In particular, when drilling through aluminum material with a 15 mm (19/32")

drill bit, the drill tends to become locked when the drill bit penetrates through the material. For this reason, the

customer should be cautioned to reduce the thrust on the main body of the drill when drilling completely

through the material to avoid locking the tool. Repeated locking of the drill causes excessive current flow from

the batteries which not only decreases the amount of work possible per charge, but could also result in

burning of the motor.

--- 13 ---

B. Suggestions and precautions for the efficient use of the charger and storage batteries

If the Types EB 1214S, EB 1220BL and EB 914S Storage Batteries are exposed to direct sunlight for an extended

period or if the tool has just been operated for a long time, charging may not be possible if the temperature of a

battery is above 40 ûC (104 ûF). In such a case, the customer should be advised to place the battery in a shaded

area with a good airflow, and allows sufficient cooling before recharging. This phenomenon is common to all

existing batteries and chargers which employ temperature sensitive overcharge protection devices. The cooling

time required before recharging can be accomplished varies from a few minutes to about 30 minutes, depending

on the load, duration of use, and ambient temperature.

9. REFERENCE MATERIALS

Speed Control Mechanism

Spindle rotation speed of the Models DS 12DVF3 and DS 9DVF3 can be controlled by simply varying the amount

by which the trigger switch is depressed. The relationship between the amount the trigger switch is depressed (in

millimeters) and the rotation speed is illustrated in Fig. 4.

NOTE: The gradient and values illustrated in Fig. 4 are intended for reference only, and will vary slightly

due to differences in the discharge condition of the battery, the ambient temperature, and

individual speed-control element accuracy.
