PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms

to the power requirements specified on the product

nameplate.

2. Power switch

Ensure that the power switch is in the OFF position.

If the plug is connected to a receptacle while the

power switch is in the ON position, the power tool

will start operating immediately, which could cause

a serious accident.

3. Extension cord

When the work area is removed from the power

source, use an extension cord of sufficient thickness

and rated capacity. The extension cord should be

kept as short as practicable.

4. Prepare a wooden workbench (Fig. 1)

Since the saw blade will extend beyond the lower

surface of the lumber, place the lumber on a

workbench when cutting. If a square block is utilized

as a workbench, select level ground to ensure it

is properly stabilized. An unstable workbench will

result in hazardous operation.

5. When using the side handle (Fig. 2)

Securely attach the side handle to the base with

the two flat head screws (M6 × 16) when using the

side handle.

CAUTION

To avoid possible accident, always ensure that the

portion of lumber remaining after cutting is securely

anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE

1. Adjusting the cutting depth

As shown in Fig. 3, hold the handle with one hand

while loosening the knob with the other.

The cutting depth can be adjusted by moving the

base to the desired position. In such manner adjust

the cutting depth and then securely retighten the

knob.

2. Adjusting the riving knife

Loosen the hexagonal - socket bolt used to clamp

the riving knife, adjust the riving knife so that the

distance between the riving knife and the rim of

the blade is not more than 3 mm, and the rim of

the blade does not extend more than 3 mm beyond

the lowest edge of the riving knife (Fig. 4) and

securely retighten the bolt.

3. Adjusting the angle of inclination

As shown in Fig. 5 (A), Fig. 5 (B) by loosening the

wing-nut on the incline gauge and the wing-bolt on

the base, the saw blade may be inclined to a

maximum angle of 45° in relation to the base. After

having completed the adjustment, reconfirm that

the wing-nut and the wing-bolt are firmly tightened.

4. Regulating the guide (Fig. 6)

The cutting position can be regulated by moving

the guide to the left or right after loosening its

wingbolt. The guide may be mounted on either the

right or left side of the tool.

5. Adjusting the guide piece

On the circular saw, it is possible to make fine

adjustment of the fixing position of the guide piece,

where the saw blade and the premarked line are

to be aligned.

When the saw is shipped from the factory, the

linear portion of a front scale on the guide piece

is aligned with the central position of the saw blade

(Fig. 7).

Loosen the fixed M4 screw on the guide piece,

should the fixing position be wrong, and make

necessary adjustment of the position.

6. Using the dust collector

To use the vacuum cleaner to gather up saw dust,

attach the suction hose to the dust collector which

is attached to the main unit by M4 and M5 screws.

When attaching the dust collector always be sure

to change the lever to the short type at this same

time (Fig. 13).

CAUTION

Continuing to use the lever that was attached to

the main unit prior to shipping from the factory will

cause it to bind on the dust collector and will

interfere with the lower guard operation.

CUTTING PROCEDURES

1. Place the base on the material, then align the

premarked line and the sawblade with the guide

piece front scale section at the front of the base

(Fig. 7).

When the base is not slanted, use the large cutout

as the guide (Fig. 7, Fig. 8 (A)).

If the base is slanted (45 degrees), use the small

front scale as the guide (Fig. 7, Fig. 8 (B)).

2. Ensure that the switch is turned to the ON position

before the saw blade comes in contact with the

lumber. The switch is turned ON when the trigger

is squeezed; and OFF when the trigger is released.

3. Moving the saw straight at a constant speed will

produce optimum cutting.

CAUTIONS

Prior to cutting operation, make sure the material you

are going to cut. If the material to be cut is expected to

generate harmful / toxic dusts, make sure the dust bag or

appropriate dust extraction system is connected with

dust outlet tightly.

Wear the dust mask additionally, if available.

A coating of PFTE is applied to the bases of the C9BU2

type. Be careful not to press too hard on the unit body

since this tends to place a heavy load on the motor.

Using a gentle pressure will make the piece slide easier

and allow cutting with less force. Trying to cut wood that

is covered with hard particle material such as sand or

metal chips tends to easily scratch damage the surface

coating so use caution.

䡬 Before starting to saw, ensure that the saw blade

has reached full speed revolution.

䡬 Should the saw blade be stopped or made an

abnormal noise during operation, turn off the switch

immediately.

䡬 Always take care in preventing the power cord from

coming near the revolving saw blade.

䡬 Using the circular saw with the saw blade facing

upwards or sideways is very hazardous. Such

uncommon applications should be avoided.
