Safety

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.
Ŷ
Maintain power tools. Check for misalignment or
binding 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.
Ŷ
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
Ŷ
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 power tool for operations
different from those intended could result in a
hazardous situation.
BATTERY TOOL USE AND CARE
Ŷ
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.
Ŷ
Use power tools only with specifically designated
battery packs.
Use of any other battery packs may
create a risk of injury and fire.
Ŷ
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 terminals together may cause
burns or a fire.
Ŷ
Under abusive conditions, liquid may be ejected
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 irritation or
burns.
SERVICE
Ŷ
Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
CIRCULAR SAW SAFETY WARNINGS
CUTTING PROCEDURES
Ŷ
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.
Ŷ
Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the workpiece.
Ŷ
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.
Ŷ
Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable platform.
It is important to support the work properly to minimize
body exposure, blade binding, or loss of control.
Ŷ
Hold power tool by insulated gripping surfaces only
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.
Ŷ
When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
Ŷ
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.
Ŷ
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 operation.
KICKBACK CAUSES AND RELATED WARNINGS:
Ŷ
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;
Ŷ
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;
Ŷ
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
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
Ŷ
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 kickback forces can be
controlled by the operator, if proper precautions are
taken.
Ŷ
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.
Ŷ
When restarting a saw in the workpiece, centre 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.
Ŷ
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.
Ŷ
Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
Ŷ
Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If blade
