1. PRODUCT NAME

Hitachi 18 V Cordless Driver Drill, Model DS 18DVF3

Hitachi 14.4 V Cordless Driver Drill, Model DS 14DVF3

2. MARKETING OBJECTIVE

The new Models DS 18DVF3 and DS 14DVF3 are upgraded versions of the current DSxxDVF2 series cordless

driver drills highly reputed as reasonable professional-use cordless driver drills. These new models are added to

reinforce the excellent cost/performance cordless driver drill series including the Models DS 9DVF3 and

DS 12DVF3 released in advance.

The Model DS 14DVF3 (battery voltage 14.4 V) is higher-performance and more convenient thanks to the

powerful motor increased in size and the angle-adjustable one-touch hook as well as the same operability as the

current Model DS 14DVF2. In addition, the Model DS 14DVF3 is balanced best with the optimally designed

position of center of gravity for various applications.

The Model DS 18DVF3 (battery voltage 18 V) is most powerful in this series. The Model DS 18DVF3 is suitable

for heavy-load works that cannot be accomplished by the Model DS 14DVF3. Although the overall length of the

Model DS 18DVF3 is 10 mm longer than the Model DS 14DVF3 owing to adoption of the new 13-mm chuck, the

overall height is equivalent to the Model DS 14DVF3 thanks to the adoption of the flat battery.

Both the Models DS 18DVF3 and DS 14DVF3 are provided with convenient standard accessories such as spare

batteries, bit set and torchlight.

3. APPLICATIONS

Tightening and loosening wood screw, self-tapping screw and machine screw

Drilling into wood materials, plastic, mild steel and aluminum

4-1. Selling Point Descriptions

4-1-1. Improved overload durability (improved cooling efficiency)

The Model DS 14DVF3 ensures durability in continuous operation thanks to the powerful motor increased in size

and the improved air ducts. The Model DS 18DVF3 is equipped with the larger motor than the Model

DS 14DVF3. (See Fig. 1.)

Fig. 1 Curves of the motor temperature rise

4-1-2. 22-position torque adjustable clutch (Max. clutch torque 5.9 N•m)

The torque can be set finely thanks to the adoption of the 22 clutch positions to improve the operability (see

Table 1).

4-1-3. Soft grip handle

The handle is widely covered with soft-touch elastomer (rubber-like soft resin). It is slip-resistant and securely fits

in the palm of a hand even if the gripping hand sweats.

4-1-4. One-touch hook

(1) The hook can be quickly slid out whenever necessary and slid in when not necessary.

(2) The hook is mountable on either side using a flat-blade screwdriver or a coin.

(3) The angle of the hook is adjustable in five steps.

4-1-5. Flat battery (DS 18DVF3)

The battery is flat enough to stand the Model DS 18DVF3 upright stability. The conventional Hitachi 18 V

batteries are also usable.

8. PRECAUTIONS IN SALES PROMOTION

8-1. Safety Instructions

In the interest of promoting the safest and most efficient use of the Models DS 18DVF3 and DS 14DVF3 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) 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.

(3) 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.

(4) 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).

(5) 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.

(6) 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.

--- 13 ---

(7) 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.

(8) Disposal of the Storage Batteries

Ensure that all customers understand that the 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.

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 Model DS 18DVF3 and

DS 14DVF3 is 1.4 Ah or 2.0 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.

--- 16 ---

(6) Precautions in the use of HSS Drill Bits

For example, although the Model DS 18DVF3 is designed for drilling capacities of 38 mm (1-1/2") in wood, and

13 mm (1/2") in aluminum and mild steel, this capability is not as efficient as conventional electric power tools.

In particular, when drilling through aluminum material with a 13 mm (1/2") 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.

(7) Securely tighten the sleeve of the keyless chuck.

The keyless chuck may slip during operation if the shape of the drill bit shank is cylindrical depending on the

surface conditions, materials, etc. Please instruct the customers to retighten the keyless chuck more securely

if the keyless chuck slips during operation. The holding force of the keyless chuck is increased as the

tightening force of the keyless chuck is increased.

(8) Avoid continuous use.

Although the Models DS 18DVF3 and DS 14DVF3 can bear continuous operation under certain conditions,

operating conditions are different depending on material of workpiece and sharpness of the drill bit in use.

Please instruct the customers to avoid continuous use of the Models DS 18DVF3 and DS 14DVF3 and take a

pause about 15 minutes after a single charge operation as a guide.

--- 17 ---

9. REPAIR GUIDE
