1. PRODUCT NAME

Hitachi Cordless Planer, Model P 20DA [82 mm (3-1/4")]

2. MARKETING OBJECTIVE

Portable cordless planers are in strong demand for light-duty work applications such as finish planing of

furnishings or timbering and planing for dimensional adjustment. Recently, there is further demand for a planer

with simple blade-height adjustment and improved operability. To satisfy such demands, the Model P 20DA was

developed as the first cordless planer in the popular 82 mm-class planers.

Although the cordless planers are below the AC-powered planers in some areas of performance such as power

and continuous run time, they have great merits in operability and handling because they require no AC power

source and have no trailing cord. The Model P 20DA is the industry's first cordless planer, so please hurry to

promote sales before other manufacturers' products enter the market.

3. APPLICATIONS

Planing of various wooden planks and panels.

6. PRECAUTIONS IN SALES PROMOTION

6-1. Safety Instructions

In the interest of promoting the safest and most efficient use of the Model P 20DA Cordless Planer 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, causes 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 0 C --- 40 C (32 F --- 104 F).

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 temperatures

under 0 C (32 F), the thermistor and thermostat do not function properly, and the storage battery may be

overcharged. At temperatures over 40 C (104 F), the storage battery cannot be sufficiently charged. The

optimum temperature range is 20 C --- 25 C (68 F --- 77 F).

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

At high ambient temperature, if more than 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. Othewise, it could cause electrical shock, fire, or other serious hazards.

--- 7 ---

CAUTION

For safe operation, see instruction manual.

Charge HITACHI rechargeable batteries type EB 7, EB 9, EB 12 and

EB 14 series. Other types of batteries may burst causing personal

injury and damage. Charge between 32 and 104 F. Indoor

use only. Replace defective cord immediately.

---

WARNING

---

To reduce the risk of injury,

user must read and understand instruction manual.

---

AVERTISSEMENT

---

Afin de réduire le risque

de lier et bien comprendre le mode d'empiol.

(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 that repair or

replacement is necessary.

(8) Disposal of the Type EB 12B Storage Battery

Ensure that all customers understand that Type EB 12B Storage Batteries should be turned in to any Hitachi

Power Tool sales outlet or 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 Plates

(1) The following caution is listed on the Name Plate attached to the main body of planer. Be particularly careful

to ensure that the customer understands the necessity of locking the switch prior to blade replacement,

cleaning, inspection or carring of the planer when not in use.

For Canada

(2) The following cautions are listed on the Name Plate attached to Model UC 14YF or UC 14YF2 Charger.

6-2. Inherent Drawbacks of the Cordless Planer Requiring Particular Attention During Sales Promotion

(1) Working performance per single charge for the first time:

The working performance per single charge for the first time may be low because the load current value is

high owing to the new and still inflexible components of the planer such as the belt. Two or three cycles of

planing and recharging the battery are required until the Model P 20DA can provide the specified performance.

Until then, adjust the cutting depth to about 0.3 mm (1/128") and perform cutting slowly while avoiding heavy-

duty cutting.

(2) Variations in working performance per single charge:

Capacity of the battery varies by 10% depending on the ambient temperature and the cycles of charging/

discharging, and also the working conditions such as ambient temperature of the planer, type and moisture

content of the wood, sharpness of the blade and the working method. Therefore, the working performance

data per single charge should be regarded as reference values.

(3) Avoid cutting of 0.5 mm (1/64") or more depth:

Avoid cutting of 0.5 mm (1/64") or more depth even though the cutting depth adjustment knob can be turned to

the position of 0.5 mm (1/64") or more. Otherwise, the planer becomes overloaded, which can cause burning

of the motor and damage of the battery.

(4) Safety switch lock mechanism

The Model P 20DA has a safety switch lock mechanism on the side of the handle. Although the position and

the shape of the safety switch lock lever are ergonomically designed for safe and easy handling in lock/off-

lock, users who are accustomed to AC-powered planers may be conscious of a little inconvenience. However,

be sure to instruct the users not to interfere with the safety switch lock lever operation by means of a piece of

wood. Refer to "Switch Operation" on the page 7 of the Handling Instructions for handling the safety switch

lock lever.

--- 9 ---

7. MAINTENANCE GUIDE

As suggestions for the use and general maintenance of the planer are covered in the Handling Instructions, only

special suggestions relative to planer blade adjustment, disassembly, reassembly and repair are described here.

Thorough attention in handling should be exercised at all times to carefully maintain the flatness and alignment

between the front and rear surfaces of the bases, and to avoid possible injury when installing, adjusting or

handling the planer blades. In addition, ensure without fail that the battery is removed from the main body prior to

carrying out maintenance, cleaning, blade replacement, etc. The [Bold] numbers in the descriptions below and

the circled numbers in the following figures correspond to the item numbers in the Parts List and exploded

assembly diagram.
