3) Personal safety
a. Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are tired or under the in
fl uence of drugs,
alcohol or medication. A moment of inattention while oper-
ating power tools may result in serious personal injury.
b. Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for appropri-
ate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the off
position before plugging in. Carrying power tools with your
fi nger on the switch or plugging in power tools that have
the switch on invites accidents.
d. Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
e. Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f. Dress properly. Do not wear loose clothing or jewellery.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes jewellery or long hair can be caught
in moving parts.
g. If devices are provided for the connection of dust extrac-
tion and collection facilities, ensure these are connected
and properly used. Use of these devices can reduce dust
related hazards.
h. Use clamps or a vice to hold work. It’s safer than using
your hand and it frees both hands to operate tool.
4) Power tool use and care
a. Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the job
better and safer at the rate for which it was designed.
b. Do not use the power tool if the switch does not turn it
on and off. Any power tool that can not be controlled with
the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source before mak-
ing any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d. Store idle power tools out of the reach of children 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.
e. Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other condi-
tion that may affect the power tools operation. If damaged,
have the power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f. Keep cutting tools sharp and clean. Properly 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 instructions and in the manner
intended for the particular type of power tool, taking into
account the working conditions and the work to be per-
formed. Use of the power tool for operations different from
intended could result in hazardous situation.
5) Service
a. Have your power tool serviced by a quali fi ed repair per-
son using only identical replacement parts. This will insure
that the safety of the power tool is maintained.
SAFETY RULES FOR CIRCULAR SAWS
DANGER
• Keep hands away from cutting area and the blade;
keep your second hand on front handle (if both hands
are holding the saw, they can not 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 piece being cut in your hands or
across your leg
(it is important to support the work prop-
erly to minimize body exposure, blade binding, or loss of
control)
• Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord
(contact with a
“live” wire will also make exposed metal parts of the tool
“live” and shock the operator)
• When ripping always use a rip fence or straight
edge guide (this improves the accuracy of cut and re-
duces the chance for blade binding)
• Always use blades with correct size and shape
of arbor holes (diamond or round) (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 bolts (the blade washers and bolt were specially de-
signed for your saw, for optimum performance and safety
of operation)
KICKBACK-CAUSES
• 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 towards operator
KICKBACK - OPERATOR PREVENTION
Kickback is the result of tool misuse and/or incorrect op-
erating procedures or conditions and can be avoided by
taking proper precautions as given below
• Maintain a fi rm grip with both hands on the saw
and position your arms to resist kickback forces; po-
sition 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)
• 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 backwards while the blade is
in motion or kickback may occur
(investigate and take
corrective actions to eliminate the cause of blade binding;
avoid cutting nails or screws)
• 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)
