d) Store idle power tools out of the reach of
children and do not allow persons unfamil-
iar with the power tool or these instruc-
tions to operate the power tool. Power tools
are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalign-
ment or binding of moving parts, breakage
of parts and any other condition that may
affect the power tool's operation. If dam-
aged, have the power tool repaired before
use. Many accidents are caused by poorly main-
tained power tools.
f) Keep cutting tools sharp and clean. Prop-
erly maintained 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 instruc-
tions, taking into account the working con-
ditions and the work to be performed. Use
of the power tool for operations different from
those intended could result in a hazardous situ-
ation.
5) Service
a) Have your power tool serviced by a quali-
fied repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
Machine-specific
Safety Warnings
DANGER: Keep hands away from cutting area
and the blade. Keep your second hand on aux-
iliary handle, or motor housing. If both hands
are holding the saw, they cannot be cut by the
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 workpiece.
Never hold the workpiece being cut in your
hands or across your leg. Secure the work-
piece to a stable platform. It is important to sup-
port the work properly to minimize body exposure,
blade binding, or loss of control.
Hold the power tool only by the insulated
gripping surfaces when performing an opera-
tion where the cutting tool may contact hid-
den wiring or its own power cord. Contact with
a "live" wire will also make exposed metal parts of
the power tool "live" and shock the operator.

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 (diamond versus round) of arbour
holes. Blades that do not match the mounting hard-
ware 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 spe-
cially designed for your saw, for optimum
performance and safety of operation.
Causes and operator prevention of kickback:
– Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an uncon-
trolled 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 incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given
below.
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 kick-
back forces can be controlled by the operator, 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
attempt 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.
