Additional Safety Warnings - Hitachi C 6U2 Handling Instructions Manual

English
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 C6U2 and C6BU2, the saw blades range
should be from 165 mm to 162 mm.
For models C7U2 and C7BU2, the saw blades range
should be from 190 mm to 185 mm.
16. Disconnect the plug from the receptacle before carrying
out any adjustment, servicing or maintenance.
17. For models C6BU2 and C7BU2, be careful of brake
kickback.
C6BU2 and C7BU2 models 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 C6BU2 and
C7BU2 models employ electric brakes. Be informed,
however, that this phenomenon is not a machine trouble.
19. For models C6BU2 and C7BU2, 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.2)
25. It is very hazardous to allow wing nut to remain loosened.
Always thoroughly clamp it. (Fig. 4)
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 C6BU2
type and C7BU2 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.
