e. ALWAYS use undamaged wheel flanges that are of correct diameter for your
selected wheel. Proper wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
f. The outside diameter and the thickness of your accessory must be within the
capacity rating of your power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
g. The arbour size of wheels and flanges must properly fit the spindle of the power
tool. Wheels and flanges with arbour holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate excessively and may
cause loss of control.
h. DO NOT use damaged wheels. Before each use, inspect the wheels for chips
and cracks. If power tool or wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing the wheel, position yourself and
bystanders away from the plane of the rotating wheel and run the power tool at
maximum no load speed for one minute. Damaged wheels will normally break
apart during this test time.
i. Wear personal protective equipment. Depending on application, use face shield,
safety goggles or safety glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stopping small abrasive or
workpiece fragments. The eye protection must be capable of stopping flying debris
generated by various operations. The dust mask or respirator must be capable
of filtrating particles generated by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
j. Keep bystanders a safe distance away from work area. Anyone entering the
work area must wear personal protective equipment. Fragments of workpiece or
of a broken accessory may fly away and cause injury beyond immediate area of
operation.
k. Hold the power tool only by the 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.
l. Position the cord clear of the spinning accessory. If you lose control of the power
tool, the cord may be cut or snagged and your hand or arm may be pulled into the
spinning accessory.
m. NEVER lay the power tool down until the accessory has come to a complete stop.
The spinning accessory may grab the surface and pull the power tool out of your
control.
n. DO NOT run the power tool while carrying it at your side. Accidental contact with
the spinning accessory could snag your clothing, pulling the accessory into your
body.
o. Regularly clean the power tool's air vents. The motor's fan will draw the dust inside
the housing and excessive accumulation of powdered metal may cause electrical
hazards.
p. DO NOT operate the power tool near flammable materials. Sparks could ignite
these materials.
q. This tool may require the use of water or other liquid coolants. It may therefore
ONLY be connected to power supplies that are protected by a RCD device. Test
the function of any RCD regularly. The use of devices utilising water or other liquid
coolants may result in electrocution or shock, if no RCD is present.
WARNING: Slots in structural walls are subject to the Standard DIN 1053 Part 1,
and/or other country-specific regulations. These regulations are to be observed under
all circumstances. Before beginning work, consult the responsible structural engineer,
architect or the construction supervisor.
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.
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.
