General Power Tool Safety
Warnings

WARNING Read all safety warnings and all

instructions. Failure to follow the warnings and

instructions may result in electric shock, fire 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

atmospheres, such as in the presence of
flammable 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. Unmodified plugs and matching outlets will

reduce risk of electric shock.

Machine screw 4 mm - 8 mm (5/32" - 5/16")

Standard bolt 5 mm - 14 mm (3/16" - 9/16")

High tensile bolt 5 mm - 12 mm (3/16" - 1/2")

BL1820B

surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of

electric shock if your body is earthed or grounded.

6. Do not expose power tools to rain or wet
conditions. 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 influence of drugs, alcohol or
medication. A moment of inattention while

operating power tools may result in serious
personal injury.

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 finger 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.

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.

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.

the risk of starting the power tool accidentally.

20. Store idle power tools out of the reach of

children 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.

Hold the tool firmly and place the point of the driver bit in
the screw head. Apply forward pressure to the tool to the
extent that the bit will not slip off the screw and turn the
tool on to start operation.

NOTE:

• Use the proper bit for the head of the screw/bolt

that you wish to use.

• When fastening screw M8 or smaller, carefully

adjust pressure on the switch trigger so that the
screw is not damaged.

• Hold the tool pointed straight at the screw.

• If you tighten the screw for a time longer than

shown in the figures, the screw or the point of the
driver bit may be overstressed, stripped, damaged,
etc. Before starting your job, always perform a test
operation to determine the proper fastening time
for your screw.

• If you use a spare battery to continue the operation,

rest the tool at least 15 min.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.

1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.

2. Driver bit or socket bit
Failure to use the correct size driver bit or socket
bit will cause a reduction in the fastening torque.

3. Bolt

• Even though the torque coefficient and the

class of bolt are the same, the proper
fastening torque will differ according to the
diameter of bolt.

• Even though the diameters of bolts are the

same, the proper fastening torque will differ
according to the torque coefficient, the class of
bolt and the bolt length.

4. The manner of holding the tool or the material of
driving position to be fastened will affect the
torque.

5. Operating the tool at low speed will cause a
reduction in the fastening torque.
