General Power Tool Safety Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and instruc-
tions may result in electric shock, re and/or serious
injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.

3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical safety
4. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodied plugs and matching outlets will
reduce risk of electric shock.
5. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet con-ditions. Water entering a power tool will increase
the risk of electric shock.
7. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
8. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
9. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of an GFCI
reduces the risk of electric shock.
Personal safety
10. Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the inuence of drugs, alcohol or medication. A moment of inattention while operating
power tools may result in serious personal injury.

(23-5/8" x 2-15/16" x 4-9/16")
11. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
12. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your nger on the switch or energising power tools
that have the switch on invites accidents.
13. Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
15. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
16. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
Power tool use and care
17. Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
18. Do not use the power tool if the switch does
not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
19. Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
20. Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
21. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
23.
Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
Battery tool use and care
24. Recharge only with the charger specied by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of re
when used with another battery pack.
25. Use power tools only with specically desig-nated battery packs. Use of any other battery
packs may create a risk of injury and re.
26. 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 termi-
nals together may cause burns or a re.
27.
Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact acci-
dentally occurs, ush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
Service
28. Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
29. Follow instruction for lubricating and changing accessories.
30.
Keep handles dry, clean and free from oil and grease.
CORDLESS SCREWDRIVER
SAFETY WARNINGS
1. Hold power tool by insulated gripping surfaces, when performing an operation where
the fastener may contact hidden wiring.
