 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 pow-
er tool for operations different from those intend-
ed could result in a hazardous situation.
Battery tool use and care
 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.
 Use power tools only with specifically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fire.
 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 fire.
 Under abusive conditions, liquid may be eject-
ed 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 irrita-
tion or burns.
Service
 Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the pow-
er tool is maintained.

Safety Warnings for Circular Saws

Cutting procedures
 DANGER: Keep hands away from the cutting
area and the saw blade.
 Do not reach underneath the workpiece. The
guard cannot protect you from the blade below
the workpiece.
 Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the
blade teeth should be visible below the work-
piece.
 Never hold piece being cut in your hands or
across your leg. Secure the workpiece to a sta-
ble platform. It is important to support the work
properly to minimize body exposure, blade bind-
ing, or loss of control.
 Hold the power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting tool may contact hidden wir-
ing. Contact with a "live" wire will also make ex-
posed metal parts of the power tool "live" and
could give the operator an electric shock.

 When ripping, always use a rip fence or
straight edge guide. This improves the accura-
cy of cut and reduces the chance of blade bind-
ing.
 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.
 Never use damaged or incorrect blade wash-
ers or bolt. The blade washers and bolt were
specially designed for your saw, for optimum
performance and safety of operation.
 Kickback causes and related warnings
– Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an un-
controlled 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 to-
ward 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 in-
correct operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
 Maintain a firm grip on the saw and position
your arms to allow you to resist kickback
force. Always stay to the side of the saw blade,
never putting the saw blade in line with your
body. The saw can jump backwards in the event
of kickback, but the operator can control kick-
back force if proper precautions are taken.
 When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the
blade comes to a complete stop. Never at-
tempt to remove the saw from the work or pull
the saw backward while the blade is in motion
or kickback may occur. Investigate and take
corrective actions to eliminate the cause of blade
binding.
 When restarting a saw in the workpiece, cen-
tre the saw blade in the kerf and check that
saw teeth are not engaged into the material. If
saw blade is binding, it may walk up or kickback
from the workpiece as the saw is restarted.
 Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the
line of cut and near the edge of the panel.
