used for appropriate conditions will reduce personal inju-
ries.
f 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 en-
ergising power tools that have the switch on invites acci-
dents.
f Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a ro-
tating part of the power tool may result in personal injury.
f Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f Dress properly. Do not wear loose clothing or jewel-
lery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
f If devices are provided for the connection of dust ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can re-
duce dust-related hazards.
Power tool use and care
f
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.
f 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.
f 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 preventive safety measures reduce the risk of
starting the power tool accidentally.
f 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.
f Maintain power tools. Check for misalignment or bind-
ing 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 maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
f Use the power tool, accessories and tool bits etc. in ac-
cordance 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.
Service
f
Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Safety Warnings for Circular Saws
Cutting procedures
f
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.
f Do not reach underneath the workpiece. The guard can-
not protect you from the blade below the workpiece.
f Adjust the cutting depth to the thickness of the work-
piece. Less than a full tooth of the blade teeth should be
visible below the workpiece.
f Never hold piece being cut in your hands or across your
leg. Secure the workpiece to a stable platform. It is im-
portant to support the work properly to minimize body ex-
posure, blade binding, or loss of control.
f Hold the power tool by the insulated gripping surfaces
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.
f Always use blades with correct size and shape (dia-
mond versus round) of arbour holes. Blades that do not
match the mounting hardware of the saw will run eccentri-
cally, causing loss of control.
f 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 opera-
tion.
f 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 oper-
ating procedures or conditions and can be avoided by tak-
ing proper precautions as given below.
f Maintain a firm grip with both hands on the saw and po-
sition 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 back-
wards, but kickback forces can be controlled by the opera-
tor, if proper precautions are taken.
f When blade is binding, or when interrupting a cut for
any reason, release the trigger and hold the saw mo-
tionless in the material until the blade comes to a com-
plete stop. Never attempt to remove the saw from the
work or pull the saw backward while the blade is in mo-
