GENErAL POwEr TOOL SAFETY wArNINGS
read all safety warnings and instructions Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
Save all warningS and inStructionS
for future reference
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) wOrk ArEA SAFETY
a) keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flam-
mable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.
2) ELEcTrIcAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets
will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power
tool. keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
e) when operating a power tool outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device
(rcD) protected supply. Use of an RCD reduces the risk of electric shock.
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 influence of drugs, alcohol
or medication. A moment of inattention while operating power tools may result in serious per-
sonal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position before connect-
ing to power source and/or battery pack, picking up or carrying the tool. Carrying power
tools with your finger on the switch or energising 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 extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce dust-
related hazards.
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
cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool
before making any adjustments, changing accessories, or storing power tools. Such pre-
ventive 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 dan-
gerous in the hands of untrained users.
e) 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.
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
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.
5) SErvIcE
a) Have your power tool serviced by a qualified repair person using only identical replace-
ment parts. This will ensure that the safety of the power tool is maintained.
ADDITIONAL SPEcIFIc SAFETY rULES
Safety Instructions for All Saws
a) 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.
b) Do not reach underneath the workpiece. The guard cannot protect you from the blade below the
workpiece.
c) 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.
d) 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.
e) Hold power 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 power tool "live" and shock the operator.
f) when ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g) Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades
that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
h) 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.
cAUSES AND OPErATOr PrEvENTION OF kIckbAck:
•
•
•
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:
a) 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.
b) 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 kick-
back may occur. Investigate and take corrective actions to eliminate the cause of blade binding.
c) 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.
d) Support large panels to minimize 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.
e) Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kickback.
f) 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.
g) Use extra caution when making a "plunge cut" into existing walls or other blind areas. The pro-
truding blade may cut objects that can cause kickback.
LOwEr GUArD SAFETY INSTrUcTIONS
a) 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 and does not touch the blade or any other part, in all
angles and depths of cut.
b) check the operation of the lower guard spring. If the guard and the spring are not operating
properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
c) Lower guard should be retracted manually only for special cuts such as "plunge cuts" and
"compound cuts." raise lower guard by retracting handle and as soon as blade enters the
material, the lower guard must be released. For all other sawing, the lower guard should operate
automatically.
d) Always observe that the lower guard is covering the blade before placing saw down on bench
423MAG
or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in
its path. Be aware of the time it takes for the blade to stop after switch is released.

ExTENSION cOrD
An extension cord must have adequate wire size (AwG or American wire Gauge) for safety.
The smaller the gauge number of the wire, the greater the capacity of the cable, that is 16 gauge

has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in
loss of power and overheating. When using more than one extension to make up the total length, be
sure each individual extension contains at least the minimum wire size. The following table shows
the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the
next heavier gauge. The smaller the gauge number, the heavier the cord.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment,
such as those dust masks that are specially designed to filter out microscopic particles.

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.
