 Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
 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.
Battery tool use and care
 Recharge only with the charger specified by the manu-
facturer. A charger that is suitable for one type of battery
pack may create a risk of fire when used with another bat-
tery pack.
 Use power tools only with specifically designated bat-
tery 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 oth-
er 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 terminals together may cause burns or a fire.
 Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally oc-
curs, flush with water. If liquid contacts eyes, addition-
ally seek medical help. Liquid ejected from the battery
may cause irritation or burns.
Service
 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
 DANGER: Keep hands away from the cutting area and
the saw blade.
 Do not reach underneath the workpiece. The guard can-
not protect you from the blade below the workpiece.
 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.
 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.
 Hold the power tool by insulated gripping surfaces on-
ly, when performing an operation where the cutting
tool may contact hidden wiring. Contact with a "live" wire
will also make exposed 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 accuracy of cut and reduces the
chance of blade binding.
 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.

 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.
 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.
 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 kickback
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 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-
tion or kickback may occur. Investigate and take correc-
tive actions to eliminate the cause of blade binding.
 When restarting a saw in the workpiece, centre the saw
blade in the kerf and check that saw teeth are not en-
gaged into the material. If saw blade is binding, it may
walk up or kickback from the workpiece as the saw is re-
started.
 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 pan-
el on both sides, near the line of cut and near the edge of
the panel.
 Do not use dull or damaged blades. Unsharpened or im-
properly set blades produce narrow kerf causing excessive
friction, blade binding and kickback.
 Blade depth and bevel adjusting locking levers must be
tight and secure before making cut. If blade adjustment
shifts while cutting, it may cause binding and kickback.
 Use extra caution when sawing into existing walls or
other blind areas. The protruding blade may cut objects
that can cause kickback.
Lower guard function
 Check lower guard for proper closing before each use.
Do not operate the saw if lower guard does not move
freely and close instantly. Never clamp or tie the lower
guard into the open position. If saw is accidentally
dropped, lower guard may be bent. Raise the lower guard
with the retracting handle and make sure it moves freely
