7. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Model C 10FM Miter 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 power saw 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 compound saw are listed in the Instruction Manual to enhance the safe, 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.

(1) Precautions on the Name Plate

Each Model C 10FM is furnished with a Name Plate that lists the following precautions.

Instruct the customer to thoroughly read the Instruction Manual prior to attempting to operate the machine.

(2) Warning Label (A)

The Warning Label (A) specified by the UL is affixed on the upper righthand portion of the motor housing. Please instruct users to strictly observe the contents in 1 to 9 in the Warning Label (A) shown at left.

--- 5 ---

8. ADJUSTMENT AND OPERATIONAL PRECAUTIONS

8-1. Confirmation of Saw Blade Lower Limit Positioning

The lower limit of the saw blade cutting depth is factory-adjusted

M6 x 20 mm hex. hd. bolt

so that when the saw blade is fully lowered, its cutting edge is 28 mm to 30 mm (1-3/32" to 1-5/32") below the upper surface of the table insert. Lower the saw blade and confirm that it stops at the correct position. If it is necessary to adjust the saw blade lower limit, loosen the 6 mm hex. nut on the M6 x 20 mm hex. hd. bolt, and turn the

6 mm hex. nut

M6 x 20 mm hex. hd. bolt if necessary. (See Fig. 3.)

Fig. 3

[CAUTION] Perform the adjustment carefully to ensure that the saw blade does not cut into the table. Also,

on completion of adjustment, ensure without fail that the 6 mm hex. nut is securely tightened.

8-2. How to Use the Vise Ass'y

(1) The vise ass'y can be mounted on either the left side

base or the right side base, and can be raised or

Knob

Vise assembly

lowered according to the height of the workpiece.

Insert the support of the vise ass'y into the hole

Support

located on either the left side base or the right side base.

Then tighten the 5 mm clamp bolt, as shown in Fig. 4.

Turn the knob to thoroughly clamp the workpiece.

[NOTE] The support has two locking grooves into which

the tip of the 5 mm clamp bolt is designed to fit, to lock the vise ass'y in the desired position.

(2) The vise ass'y can be mounted on either the left side

fence or the right side fence, and can be raised or lowered according to the height of the workpiece. Insert the support of the vise ass'y into the hole

located on either the left side fence or the right side fence.

Then tighten the 5 mm clamp bolt, as shown in Fig. 5.

Turn the knob to thoroughly clamp the workpiece.

[Warning] Always firmly clamp or vise to secure the workpiece to the fence; otherwise the workpiece

might be thrust from the table and cause bodily harm.

8-3. Cutting Operation

(1) Cutting efficiency will be reduced if a dull saw blade is used, if an excessively long extension cord is used, or if

the wire gauge of the extension cord is too small. (For details on extension cords, please refer to the Instruction Manual.) This is particularly important when cutting materials with dimensions which are at or near the maximum capacity for the machine.

(2) The customer should be advised to thoroughly inspect the workpiece to ensure that there are no metallic

objects (nails in particular), sand, or other foreign matter in or on the workpiece. Saw blade contact with such foreign matter will not only shorten the service life of the saw blade, but could cause serious accident. Should the saw blade tips be broken off, the tips may fly toward the operator.

(3) Press cutting

Like Mode C 10FC2, C 10FM can be used for press cutting of workpieces up to 66 mm x 144 mm (2-19/32" x 5-11/16") in a single operation by simply pushing the saw blade section (head) downward. The customer should be cautioned that excessive pressure on the handle will not increase the cutting speed. On the contrary, excessive pressure may result in reduced cutting efficiency (irregular or rough cutting of the workpiece), and could also cause overload and subsequent burnout of the motor. On completion of the cutting operation, turn the switch OFF and wait for the saw blade to come to a complete stop before raising the saw blade section (head) to its original position. Raising the saw blade section (head) while the saw blade is rotating may cause unwanted cutting marks on the workpiece.

Techniques to avoid unwanted cutting marks Uneven and unwanted cutting marks can be avoided throughout the cutting operation by gently and smoothly pressing down on the handle, so that the entire cutting operation is accomplished in a single uninterrupted motion.

(4) Miter cutting

Miter cutting is accomplished by turning the table. (For details, please refer to the Instruction Manual.)

--- 7 ---

(5) Cut surface quality during miter cutting

The quality of the cut surface depends on the type of cutting operation (miter), the type and sharpness of the saw blade, whether the workpiece is cut to the right or left. In miter cutting in particular, cutting is performed across the wood grain, so the condition of the cut surface depends on whether the wood is cut with or against the grain. This is the same as when using electric portable planers. Customers should be advised of these phenomena so that they understand that in cases when the cut surface may not be as smooth as expected or hoped for, it is not caused by the performance of the saw blade or the Model C 10FM. In the cutting examples illustrated in Fig. 6, the cut surfaces on the sides marked are better than those on the sides marked .

[Miter cutting]

Better Better

9. PACKING

The main body of the Model C 10 FM is sandwiched between packing (A) and packing (B) made of styrofoam. This system makes the packaging work easier.

(1) Preparation

Remove the vise ass'y and dust bag from the main unit. Then swivel the table through 45˚ toward the right. Fix the table securely with the miter handle. Push down the head section and insert the locking pin to secure the head section at the lower position.

(2) How to install packing (A)

Put packing (A) in the carton box. Put the main unit in packing (A).

(3) How to install packing (B)

Put packing (B) on the main unit. Put the vise ass'y and the dust bag in the groove of packing (B). Close the lids of the carton box and bind them together.
