Hitachi C18DSL-LL [4/208] Additional safety warnings
4
English
For all other sawing, the lower guard should operate
automatically.
d) Always observe that the lower guard is covering the
blade before placing saw down on bench or fl oor.
An unprotected, coasting blade will cause the saw to
walk backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to stop after
switch is released.
ADDITIONAL SAFETY WARNINGS
1. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
2. Never disassemble the rechargeable battery and
charger.
3. Never short-circuit the rechargeable battery.
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
4. Do not dispose of the battery in fi re. If the battery is burnt,
it may explode.
5. When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch. Therefore,
whenever the housing becomes hot, give the saw a
break for a while.
6. Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or infl ammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
7. Bring the battery to the shop from which it was purchased
as soon as the post-charging battery life becomes too
short for practical use. Do not dispose of the exhausted
battery.
8. Use only blade diameter specifi ed on the machine.
9. Do not use any abrasive wheel.
10. Do not use saw blades which are deformed or cracked.
11. Do not use saw blades made of high speed steel.
12. Do not use saw blades which do not comply with the
characteristics specifi ed in these instructions.
13. Do not stop the saw blades by lateral pressure on the
disc.
14. Always keep the saw blades sharp.
15. Ensure that the lower guard moves smoothly and freely.
16. Never use the circular saw with its lower guard fi xed in
the open position.
17. Ensure that the retraction mechanism of the guard
system operates correctly.
18. Never operate the circular saw with the saw blade turned
upward or to the side.
19. Ensure that the material is free of foreign matters such as
nails.
20. The saw blades range should be from 165 mm to
150 mm.
21. 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.3)
To avoid possible accident, always ensure that the
portion of lumber remaining after cutting is securely
anchored or held in position.
22. Be careful of brake kickback.
This circular saw 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.
23. Do not fi x and secure the switch lock. Besides, keep
your fi nger off the switch trigger when the circular saw is
being carried around. Otherwise, the main body switch
can be inadvertently turned ON, resulting in unexpected
accidents.
24. 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.
25. Before starting to saw, ensure that the saw blade has
reached full speed revolution.
26. Should the saw blade be stopped or made an abnormal
noise during operation, turn off the switch immediately.
27. Twisting and forcibly pressing the saw during cutting can
result in unreasonable pressure on the motor, so try to go
straight quietly.
28. Avoid cutting operation in a state where the base bottom
is afl oat from the material being cut. Otherwise, the
motor can get locked.
29. Preparing and checking the work environment. Make
sure that the work site meets all the conditions laid forth
in the precautions.
30. Make sure that the battery is installed fi rmly. If it is as all
loose it could come off and cause an accident.
31. When fi nished with a job, pull out the battery from the
main body.
32. After having attached the saw blade, reconfi rm that the
lock lever is fi rmly secured in the prescribed position.
33. If the left-hand bolt is worked using other tools than
the provided box wrench, excessive tightening and
insuffi cient tightening may take place resulting in injury.
34. After adjusting cutting depth, make sure to securely
tighten the butterfl y nut. Failure to do so may result in
injury. (Fig.4)
35. After adjusting the angle of inclination, make sure to
securely tighten the butterfl y nut. Failure to do so may
result in injury. (Fig.5)
36. Values of the inclined gauge provided on the base merely
serve as a rough guideline. For cutting operation at an
inclined posture, use the circular saw after adjusting
the angle between the base and the saw blade with a
protractor, etc.
37. Pull out battery before carrying out any adjustment,
servicing or maintenance.
38. Ensure that the switch is in the OFF position. If the battery
installed to power tool while the switch is in the ON
position, the power tool will start operating immediately,
which could cause a serious accident.
39. If the main body is left as it is with the battery inserted,
there can be a case where the [switch lock] touches
the fl oor and/or wall surface and lights up continuously,
depending on the direction of the body. Be careful,
since continuous lighting can easily make a full-charged
battery go dead.
40. Never attempt to saw with the circular saw held upside
down in a vise. This is extremely dangerous and can
lead to serious accidents (Fig. 11).
41. Keep the light ON during cutting operation only. If
it is lit ON in other cases, the main body switch can
be inadvertently turned ON, resulting in unexpected
accidents.
42. Immediately after the light is turned OFF, the bulb retains
high temperature. Make sure to cool down the light bulb
thoroughly before replacing it so as to prevent burns.
43. When replacing the light bulb, check the shape of base
as well as the rating (12 V, 5 W), and then carry out
perfect mounting. Otherwise, the light bulb can come off
and/or cause overheat.
