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. 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, however, if precautions are
taken, kickback forces can be controlled by the operator.
b) When the blade is binding, or when interrupting a cut for any reason, release the
trigger and hold the saw motionless in the workpiece 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. Investigate and take corrective action to
eliminate the cause of blade binding.
c) When restarting a saw within an incomplete cut, centre the saw blade in the kerf and
check that the saw teeth are not engaged into the material (a binding saw blade may
‘propel upwards’ or kickback from the workpiece as the tool is restarted).
d) A large workpiece should be supported close to the line of the cut, and at the edge
of the panel, to prevent sagging. This will minimise the risk of blade pinching and
kickback.
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 making a ‘plunge cut’ into existing walls or other blind areas.
The protruding blade may cut objects causing 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.

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
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
