the tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch
on invites accidents.
d) Remove any adjusting key or wrench before turn-
ing the power tool on. A wrench or a key left at-
tached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
Dress properly. Do not wear loose clothing or
f)
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
g) 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.
2.1.4 Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) 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 opera-
tions different from those intended could result in a
hazardous situation.
2.1.5 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.

2.2 Safety instructions for all saws
2.2.1 Cutting procedures
a)
DANGER
Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or
motor housing. If both hands are holding the saw,
they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the work-
piece.
c) Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
d) Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable plat-
form. It is important to support the work properly to
minimize body exposure, blade binding, or loss of
control.
e) Hold the power tool by insulated gripping sur-
faces only, when performing an operation where
the cutting tool may contact hidden wiring or its
own cord. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
f) When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw
will run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and
safety of operation.
2.2.2 Further safety instructions for all saws
Kickback causes and related warnings
kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator;
when the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;
if the blade becomes twisted or misaligned in the cut, the
teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the
kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade, but
not in line with the blade. Kickback could cause the
saw to jump backwards, but kickback forces can be
controlled by the operator, if proper precautions are
taken.
