e) Do not operate the saw if riving knife is bent.

Even a light interference can slow the closing rate of a

guard.

ADDITIONAL SAFETY WARNINGS

1. Use only blade diameter specifi ed on the machine.

2. Do not use any abrasive wheel.

3. Do not use saw blades which are deformed or cracked.

4. Do not use saw blades made of high speed steel.

5. Do not use saw blades which do not comply with the

characteristics specifi ed in these instructions.

6. Do not stop the saw blades by lateral pressure on the

disc.

7. Always keep the saw blades sharp.

8. Ensure that the lower guard moves smoothly and freely.

9. Never use the circular saw with its lower guard fi xed in

the open position.

10. Ensure that the retraction mechanism of the guard

system operates correctly.

11. The saw blades body must be thinner than the riving

knife and the width of cut, or kerf (with teeth set) must be

greater than the thickness of the riving knife.

12. Never operate the circular saw with the saw blade turned

upward or to the side.

13. Ensure that the material is free of foreign matters such as

nails.

14. The riving knife should always be used except when

plunging in the middle of the workpiece.

15. For models C9U2 and C9BU2, the saw blades should be

235 mm.

16. Disconnect the plug from the receptacle before carrying

out any adjustment, servicing or maintenance.

17. For model C9BU2, be careful of brake kickback.

C9BU2 model features an electric brake that functions

when the switch is released. As there is some kickback

when the brake functions, be sure to hold the main body

securely.

18. Sparks can sometimes appear caused by braking

operation when the switch is turned off since

C9BU2 model employs electric brakes. Be informed,

however, that this phenomenon is not a machine trouble.

19. For model C9BU2, when the brake becomes ineff ective,

replace the carbon brushes with new ones.

20. Ensure that the power source to be utilized conforms

to the power requirements specifi ed on the product

nameplate.

21. 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.

22. When the work area is removed from the power source,

use an extension cord of suffi cient thickness and rated

capacity. The extension cord should be kept as short as

practicable.

23. 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.

(Fig.1)

To avoid possible accident, always ensure that the

portion of lumber remaining after cutting is securely

anchored or held in position.

24. Should knob remain loosened, it will create a very

hazardous situation. Always thoroughly clamp it. (Fig.3)

25. It is very hazardous to allow wing bolt to remain loosened.

Always thoroughly clamp it. (Fig.5)

26. 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.

○ Before starting to saw, confi rm that the saw blade

has attained full-speed revolution.

○ Should the saw blade stop or make an abnormal

noise while operating, promptly turn OFF the switch.

○ Always take care in preventing the power cord from

coming near to the revolving saw blade.

○ Using the circular saw with the saw blade facing

upwards or sideways is very hazardous. Such

uncommon applications should be avoided.

○ When cutting materials, always wear protective

glasses.

○ When fi nished with a job, pull out the plug from the

receptacle.

27. After having attached the saw blade, reconfi rm that the

lock lever is fi rmly secured in the prescribed position.
