Keep cutting tools sharp and clean. Properly main-
u
tained 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
u
accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
Keep handles and grasping surfaces dry, clean and
u
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
Battery tool use and care
Recharge only with the charger specified by the manu-
u
facturer. A charger that is suitable for one type of bat-
tery pack may create a risk of fire when used with another
battery pack.
Use power tools only with specifically designated bat-
u
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
u
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 terminals together may cause burns
or a fire.
Under abusive conditions, liquid may be ejected from
u
the battery; avoid contact. If contact accidentally oc-
curs, flush with water. If liquid contacts eyes, addi-
tionally seek medical help. Liquid ejected from the bat-
tery may cause irritation or burns.
Do not use a battery pack or tool that is damaged or
u
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
of injury.
Do not expose a battery pack or tool to fire or excess-
u
ive temperature. Exposure to fire or temperature above
130°C may cause explosion.
Follow all charging instructions and do not charge the
u
battery pack or tool outside the temperature range
specified in the instructions. Charging improperly or at
temperatures outside the specified range may damage
the battery and increase the risk of fire.
Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Never service damaged battery packs. Service of bat-
u
tery packs should only be performed by the manufacturer
or authorized service providers.

Cutting procedures
DANGER: Keep hands away from cutting area and
u
the blade. If both hands are holding the saw, they cannot
be cut by the blade.
Do not reach underneath the workpiece. The guard
u
cannot protect you from the blade below the workpiece.
Adjust the cutting depth to the thickness of the work-
u
piece. Less than a full tooth of the blade teeth should be
visible below the workpiece.
Never hold the workpiece in your hands or across your
u
leg while cutting. Secure the workpiece to a stable
platform. It is important to support the work properly to
minimise body exposure, blade binding, or loss of con-
trol.
Hold the power tool by insulated gripping surfaces,
u
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
u
guide. This improves the accuracy of cut and reduces the
chance of blade binding.
Always use blades with correct size and shape (dia-
u
mond versus round) of arbour holes. Blades that do not
match the mounting hardware of the saw will run off-
centre, causing loss of control.
Never use damaged or incorrect blade washers or
u
bolt. The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of op-
eration.
Kickback causes and related warnings
- kickback is a sudden reaction to a pinched, jammed or mis-
aligned saw blade, causing an uncontrolled saw to lift up and
out of the workpiece toward the operator;
- when the blade is pinched or jammed 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 sur-
face 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 operat-
ing 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
u
to resist kickback forces. Position your body to either
side of the blade, but not in line with the blade. Kick-
back could cause the saw to jump backwards, but kick-
back forces can be controlled by the operator, if proper
precautions are taken.
When blade is binding, or when interrupting a cut for
u
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
