• Always use saw blades of the correct diameter and with the correct mounting hole
(e.g. diamond-shaped or round). Circular blades that do not match the mounting
saw's adaptor will run unevenly, causing you to lose control of the tool.
• Never use damaged or incorrect washers or screws to secure the saw blade.
Included in box washers and bolts have been designed for your saw to ensure
optimal performance and maximum safety.
Kickback - causes and corresponding safety rules:
- Kickback is a sudden reaction, due to a caught, jammed or poorly guided saw
blade, that causes the saw to jump out of the workpiece in an uncontrolled manner
towards the operator.
- When the saw blade catches, binds or becomes stuck in a workpiece, the force of
the motor throws the saw towards the operator.
- If the saw blade twists, for example due to poor guiding of the saw, the rear teeth
of the saw blade may catch on the wood and cause it to be thrown out of the cut
and jump towards the operator.
Kickback is the result of improper or un-experienced operation of the saw. This can
be prevented by taking the precautions described below.
• Hold the circular saw with both hands, positioning the arms so that you can absorb
the rebound force. Stay to the side of the saw blade, i.e. never stand in line with it.
In the event of a kickback, the saw may spring back, but the operator of the saw
can absorb the force of the kickback if appropriate precautions are taken.
• If the saw blade gets jammed or stops working, switch the saw off and wait for the
saw blade to stop revolutions, without removing the saw blade from the workpiece.
Never try to lift or move the saw in the opposite direction from the workpiece until
the saw blade has stops moving, otherwise kickback may occur. Then identify and
remove the reason of jamming of saw blade.
• If you want to restart the saw without removing it from the workpiece, center the
saw blade in the cut and make sure that the cutting teeth are not caught in the
workpiece. If the saw blade gets/remains caught in the workpiece, it may spring
out of the workpiece, causing a kickback when the saw is restarted.
• Larger boards should be supported, minimizing the risk of kickback of a jammed
saw blade. Larger plates may bend under their own weight. The boards must be
supported on both sides, preferably near the kerf and at the edges.
• Do not use a dull or damaged circular saw blade. Circular saw blades with blunt or
poorly positioned teeth cause increased friction, making the blade jammed and
cause risk of kicback.
• Before starting work, tighten depth and angle setting elements. Uncontrolled and
unplanned change of settings of saw may jam blade and cause kickback.
• Be careful especially when cutting though some walls and areas that you cannot see
from the other side. If the saw blade gets immersed into a partially hidden object, it
can jam and cause a kickback.
Bottom guard/cover operation
• Before each use of the saw, make sure that the lower guard closes smoothly. Do
not turn on the saw unless the lower guard is moving freely and closes immediate
ly. Never lock or tie the bottom guard in the open position. If circural saw falls to
the floor, the bottom guard may bend. Open the guard with the return lever and
make sure that the guard moves freely and that it does not touch the saw blade or
other parts of the saw at any angle and depth of cut settings.
• Check the operation of the spring of the lower guard. Have the saw serviced if the
bottom guard and/or spring are not working properly. Damaged parts, sticky
deposits, or a build-up of chips may delay the operation of the lower cover.
