- 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 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.
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 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 kick back from the workpiece as the saw is restarted.
d) Support large panels to minimum 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 a
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 that can cause kickback.

Guard function
a) Check the guard for proper closing before each use. Do not operate the saw if the
guard does not move freely and enclose the blade instantly. Never clamp or tie the
guard with the blade exposed. If the saw is accidentally dropped, the guard may be bent.
Check to make sure that guard moves freely and does not touch the blade or any other part,
in all angles and depths of cut.
b) Check the operation and condition of the guard return spring. If the guard and the
spring are not operating properly, they must be serviced before use. The guard may
operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
c) Assure that the base plate of the saw will not shift while performing a "plunge cut".
Blade shifting sideways will cause binding and likely kick back.
d) Always observe that the guard is covering the blade before placing saw down on
bench 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.
Track Plunge 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.
•
Do not allow anyone under the age of 18 years to operate this saw
•
When operating the saw, use safety equipment including safety goggles or shield, ear
protection, dust mask and protective clothing including safety gloves
•
Hand-held power tools may produce vibration. Vibration can cause disease. Gloves may
help to maintain good blood circulation in the fingers. Hand-held tools should not be used
for long periods without a break
•
Always use recommended blades with correct size and shape of arbor holes e.g.
diamond or round. Blades that do not match the mounting hardware of the saw will run
eccentrically, causing loss of control
•
Whenever possible, use a vacuum dust extraction system to control dust/waste
•
Power tools must always be held by the insulated gripping surfaces when performing
an operation, ensuring protection if the cutting tool makes contact with its own cord or
hidden wiring. Contact with a 'live' wire will make exposed metal parts of the power tool
'live' and shock the operator if the insulated gripping surfaces are not used
•
Ensure hands are kept away from the cutting area and blade. Keep one hand on the
auxiliary handle or motor housing. If both hands are holding the tool they cannot be cut
EN
by the blade
•
Do not attempt to cut material thicker than detailed in the Specifications section of this
manual
•
Adjust the cutting depth to the thickness of the workpiece i.e. less than a full tooth of the
blade should be visible below the workpiece
•
Ensure that work is correctly supported. Large panels may sag under their own weight and
bind the saw blade. Supports must be placed under the panel on both sides, close to the
line of cut and near the edge of the panel
•
Ensure all supports and power cables are completely clear of the cutting path
•
Always secure the workpiece to a stable platform, ensuring body exposure is minimised,
avoiding blade binding, or loss of control
•
For accuracy of cut, and to avoid blade binding, always use a rip fence or straight edge

•
Never hold a workpiece in your hand or across your legs whilst cutting
•
Always stand at an angle to the tool when operating
•
Be aware that the blade will project from the underside of the workpiece
•
Do not reach beneath the workpiece where the guard cannot protect you from the blade
•
Note the direction of rotation of the motor and the blade
•
Inspect the workpiece and remove all nails and other embedded objects prior to starting
work
•
Do not apply any sideways or twisting force to the blade whilst cutting
•
If a cut does not extend to the edge of the workpiece, or if the blade binds in the cut, allow
the blade to come to a complete stop and lift the saw out of the workpiece
•
Do not attempt to free a jammed blade before first disconnecting the machine from power
•
Do not move the saw backwards at any time whilst cutting
•
Beware of projected waste. In some situations, waste material may be projected at speed
from the cutting tool. It is the user's responsibility to ensure that other people in the work
area are protected from the possibility of projected waste
•
If you are interrupted when operating the saw, complete the process and switch off before
diverting your attention
•
The blade bolt and washers were specially designed for your saw. For optimum
performance and safety of operation never use damaged or incorrect bolt/blade washers
•
Check the lower guard for proper closing before each use. Do not operate the saw if the
lower guard does not move freely and close instantly. Never clamp or tie the lower guard
into the open position. If the saw is accidentally dropped, the 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
•
Always observe that the lower guard is covering the blade before resting the saw on a
surface after use. An unprotected, coasting blade will cause the saw to move backwards,
cutting whatever is in its path. Be aware of the time it takes for the blade to stop after the
trigger switch is released
•
Periodically check that all nuts, bolts and other fixings have not loosened, tighten where
necessary

Even when the tool is used as prescribed it is not possible to eliminate all residual risk factors.
Kickback Prevention & Operator Safety
When used in the track, this plunge saw includes an integral anti-kickback device to help
prevent the saw lifting up out of the workpiece. The following provides guidance on measures
to prevent kickback occurring:
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
