Hitachi WF 14DSL Handling Instructions Manual page 41

5) Battery tool use and care
a) Recharge only with the charger specified by the
manufacturer.
A charger that is suitable for one type of battery
pack may create a risk of fire when used with
another battery pack.
b) Use power tools only with specifically designated
battery packs.
Use of any other battery packs may create a risk
of injury and fire.
c) When battery pack is not in use, keep it away
from other metal objects like paper clips, coins,
keys, nails, screws, or other small metal objects
that can make a connection from one terminal
to another.
Shorting the battery terminals together may
cause burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause
irritation or burns.
6) Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.
PRECAUTIONS FOR CORDLESS AUTOMATIC
SCREWDRIVER
1. Hold power tool by insulated gripping surfaces,
when performing an operation where the fastener
may contact hidden wiring. Fasteners contacting a
"live" wire may make exposed metal parts of the
power tool "live" and could give the operator an
electric shock.
2. Always charge the battery at a temperature of
0 – 40°C. A temperature of less than 0°C will result
in over charging which is dangerous. The battery
cannot be charged at a temperature higher than
40°C.
The most suitable temperature for charging is that
of 20 – 25°C.
3. Do not use the charger continuously.
When one charging is completed, leave the charger
for about 15 minutes before the next charging of
battery.
4. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
5. Never disassemble the rechargeable battery and
charger.
6. Never short-circuit the rechargeable battery. Short-
circuiting the battery will cause a great electric
current and overheat. It results in burn or damage
to the battery.
7. Do not dispose of the battery in fire.
If the battery is burnt, it may explode.
8. 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.
9. Using an exhausted battery will damage the charger.
10. Do not insert object into the air ventilation slots of
the charger.
Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical
shock hazard or damaged charger.
11. When mounting a bit into the keyless chuck, tighten
the sleeve adequately. If the sleeve is not tight, the
bit may slip or fall out, causing injury.
12. This automatic screwdriver is designed for
tightening and loosening screws. Use it only for
these operation.
13. One-hand operation is extremely dangerous; hold
the unit firmly with both hands when operating.
14. Use original bits specifically for the automatic
screwdriver.
Use no bits other than the original bits specifically
for the automatic screwdriver. Use of any other
bit can result in screws sticking out and screw
feed malfunctioning.
15. After installing the driver bit, pull lightly out the
bit to make sure that it does not come loose. If
the bit is not installed properly, it can come loose
during use, which can be dangerous.
16. Screw in screws with the main unit held straight.
If the driver is slanted relative to the screw, the
screw head can be damaged and the bit worn.
Moreover, the prescribed torque is not transmitted
to the screw, resulting in screws left sticking out.
Place the drive straight against the screw and
screw in.
17. Use the prescribed screws.
Do not use any other screws. They can cause
abnormal work (screws fallen over or sticking out)
and break downs (screw jamming and bit wear).
18. Protect your eyes with protective glasses.
Always wear protective glasses while working.
Drilling scatters plaster powder and tape dust,
which are dangerous if they get into your eyes
19. Watch out for wires and pipes in walls and ceilings.
When working on floors, walls, or ceilings, check
for wires and pipes ahead of time. Work carefully
to avoid shocks and explosions.
20. When the screw feed attachment is removed,
always use the correct driver bit for the screw size.
21. When the screw feed attachment is removed, if
the screwdriver is positioned at an angle against
the tightening screw, the head of the screw may
be damaged or the fixed tightening force will not
transfer to the screw. Always position the
tightening screw and the screwdriver at a straight
angle and then tighten the screw.
22. This product contains a strong permanent magnet
in the motor.
Observe the following precautions regarding
adhering of chips to the tool and the effect of the
permanent magnet on electronic devices.
CAUTION:
Do not place the tool on a workbench or work area
where metal chips are present.
The chips may adhere to the tool, resulting in injury
or malfunction.
