Kickback Prevention and
Operator Safety
- 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
Kickback is the result of saw misuse and/or incorrect operating procedures or conditions
and can be avoided by taking precautions as follows:
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.
Note:
For circular saws with 140 mm or smaller diameter blades, the words “with both
hands” may be omitted.
b. When the 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.
c. When restarting a saw in the workpiece, centre the saw blade in the kerf and
check that the 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 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
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 a cut.
If blade adjustment shifts while cutting, it may cause binding and
kickback.
g. Use extra caution when sawing into existing walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
h. Check the lower guard before each use and do not use if it does not close freely,
ensuring that the blade does not touch any part of the guard or tool in all angles and
depths of cut. Never clamp or tie the lower guard in the open position.
i. Check the operation of the lower guard spring. If the guard and the spring are not
operating correctly, they must be serviced before use. The lower guard may operate
sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
j. The lower guard should be retracted manually only for special cuts such as ‘plunge
cuts’ and ‘compound cuts.’ Raise the lower guard by the retracting handle and as soon
as the blade enters the material, the lower guard must be released. For all other sawing,
the lower guard should operate automatically.
k. Ensure that the lower guard is covering the blade before placing the saw down. An
unprotected, coasting blade will cause the saw to ‘propel backwards’, cutting whatever
is in its path. Be aware of the time it takes for the blade to stop after the switch is
released. Do not use abrasive wheels, doing so will void the warranty.
l. If a circular saw features a riving knife it must be removed before plunge cutting. A
riving knife will interfere with a plunge cut causing kickback. The riving knife must
always be re-fitted after plunge cutting. A circular saw with a permanent, non-
removable riving knife is NOT suitable for plunge cutting.
Circular Saw Safety
WARNING: Before connecting a tool to a power source (mains switch power point
receptacle, outlet, etc.) be sure that the voltage supply is the same as that specified on
the nameplate of the tool. A power source with a voltage greater than that specified for
the tool can result in serious injury to the user, and damage to the tool. If in doubt, do not
plug in the tool. Using a power source with a voltage less than the nameplate rating is
harmful to the motor.
DANGER: Keep hands away from cutting area and the blade. Keep your second hand
on the auxiliary, or motor housing.
If both hands are holding the saw, they cannot be
cut by the blade.
Note: For circular saws with 140 mm or smaller diameter blades, the “keep your second
hand on auxiliary handle, or motor housing” may be omitted.
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.

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
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 personal 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
connecting 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
Power tool use & 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 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 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
WARNING:
When used in Australia or New Zealand, it is recommended that this tool
is ALWAYS supplied via Residual Current Device (RCD) with a rated residual current of
30mA or less.
Service
a) 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
