1. PRODUCT NAME

Hitachi Table Saw, Model C 10RA2

2. MARKETING OBJECTIVE

The Model C 10RA2 was developed to upgrade and replace the current Model C 10RA. The key features of the Model C 10RA2 are as follows: (1) Smooth-sliding fence mounted on rails at the front and the rear of the table (2) One-touch fence setting, thanks to a quick lock fence system (3) More stable guide of a workpiece with the 3-inch-heigh fence (C 10RA: 2-inch height) The basic structure of the product is the same as that of the Model C 10RA.

3. APPLICA TIONS

Rip-sawing and cross-cutting of ordinary wood, hardwood, plywood, composite wood materials, plastics and similar materials.

7. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Model C 10RA2 Table Saw 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 Instruction Manual, and fully understands the meaning of the precautions listed on the various caution plates attached to each machine.

7-1. Instruction Manual

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 electric tool cannot be completely eliminated. Accordingly, general precautions and suggestions for the use of electric power tools, and specific precautions and suggestions for the use of the table saw are listed in the Instruction Manual to enhance the safe and efficient use of the tool by the customer. Salespersons must be thoroughly familiar with the contents of the Instruction Manual to be able to offer appropriate guidance to the customer during sales promotion.

7-2. Precautions on the Name Plate

Each Model C 10RA2 is furnished with a Name Plate that lists the following precautions:

CAUTION

• For Safe operation, see Instruction Manual.

• Always wear eye protection.

• Do not use saw blade rated below 6000 rpm.

• Use guards with saw blade.

••••••••••••••••••••••••••••••••••••

1 2 3 4

(1) Instruct the customer to read the Instruction Manual thoroughly prior to attempting to operate the machine. (2) As cutting chips or sawdust flying into the eyes of the operator could result in loss of sight, it is absolutely

necessary to caution the customer to wear protective glasses whenever operating the machine.

(3) Instruct the customer never to use a saw blade with a rated maximum rotation speed of less than 6,000 /min.

If a saw blade with a rated maximum rotation speed of less than 6,000 /min is used, there is a danger that one or more of the blade tips could fly off unexpectedly and cause serious injury to the operator or anyone else in the immediate area.

(4) Instruct the customer to confirm without fail that all saw blade guards and other safety devices furnished with

the machine are properly mounted before attempting to operate the machine.

7-3. Warning Label (A)

WARNING

For Your Own Safety Read Instruction

Manual Before Operating Table Saw

1. Wear eye protection.

2. Use saw blade guard and spreader for every operation for which it can be used, including all through sawing.

3. Keep hands out of the line of saw blade.

4. Use a push stick when required.

5. Pay particular attention to instructions on reducing risk of kickback.

6. Do not perform any operation freehand.

7. Never reach around or over saw blade.

This is mounted on the right side of the body shell. Please instruct users to strictly observe the contents of 1 to 7 in the warning label shown at left. (Warning Label (A) is not provided on some areas' models.)

N392456

--- 6 ---

(1) Be sure to wear the protective glasses. (2) Advise the user to use the saw blade guard and spreader when using the table saw. The saw blade guard

prevents the operator from touching the saw blade and the dislodging of workpieces. This should be

employed to ensure safety. (3) Take care to keep the hands away from the saw blade. (4) Explain the procedure for making and using the push stick (optional accessory) to the user. Details are

contained in the Instruction Manual (refer to page 17, 8. Work Helpers). Advise the user to use the push stick

when cutting a narrow workpiece vertically. (5) If the workpiece dislodges, it may injure the operator.

Follow the dislodging preventive measures in the Instruction Manual. Advise the user to check that the

dislodging preventive claw (anti-kickback pawls) works correctly and the claw (anti-kickback pawls) edge is

sharp enough to bite into the workpiece before starting operation. (6) Use both hands during cutting work. For cross cutting, hold the workpiece and miter gauge securely.

For vertical cutting, hold the workpiece and press it onto the rip fence surface securely by hand. These

precautions are fundamental to cutting work. (7) Never get too close to the saw blade and be especially careful about the exposed rotating teeth.

7-4. Warning Label (B)

WARNING

For Your Own Safety Read Instruction

Manual Before Operating Table Saw

1. Never operate the power tool if the saw blade guard does not function smoothly.

2. Never remove guard (including saw blade guard spreader) from the tool body when you operate it (except dado cutting.)

3. Always confirm that the rotary and saw blade directions are the same.

4. The saw blade tilt lock handle must be locked during all cutting operations.

5. Never operate to pull the workpiece back with the saw blade turning.

N392464

This is mounted on the right side of the body shell. Please instruct users to strictly observe the contents of 1 to 5 in the warning label shown at left.

(1) The saw blade guard is designed to protect the operator from coming into contact with the saw blade during

operation of the tool. (2) The saw blade guard and spreader are for safe operation. Do not operate the machine without the saw blade

guard and spreader (except for dado cutting). (3) When mounting the saw blade, check that the saw blade's direction of rotation matches the machine's

direction of rotation. (4) Be sure to lock the tilt lock handle to prevent tilting of the saw blade during operation. (5) If the wood is pulled toward the operator during cutting, it may be repelled by the saw blade (kickback). Never

pull the wood toward the operator during cutting.

7-5. Package

The table saw Model C 10RA2 is divided into the main body and the saw blade guard sections before packing and shipping. Therefore, buyers of this machine are required to perform some light assembly. Instruct customers to carefully read the assembly procedure in the Instruction Manual.

7-7. Related Laws and Regulations

The Model C 10RA2 has passed the C-UL standard. Therefore, the operator's safety is assured if it is operated according to the Instruction Manual. The most important thing is to familialize the user with the machine, so advise the user on correct operation and thus ensure the user's safety. Misoperation will cause a serious accident. Please be very careful in advising the user.
