
Wear suitable clothing. Do not wear loose-fitting clothing or gloves as these can get caught in
moving parts. Loose-fitting clothing, jewellery and long hair can get caught in moving parts.

If dust extraction and dust collection equipment is provided, this should be connected and used
correctly. The use of such devices can reduce the risk of dust-related hazards.

Secure the workpiece with a clamp, vice or clips. This is safer than using your hands, and means
you have both hands free to operate the tool.
Important safety instructions for circular saws
DANGER

Keep your hands away from the cutting area and blade. Hold your other hand on the extra handle
or motor casing. If you hold the tool with both hands, they cannot come into contact with blade.

Do not put your hand under the workpiece. The guard does not protect you from the blade under
the workpiece.

Adjust the cutting depth to the thickness of the workpiece. Slightly less than a full tooth on the
blade should be visible below the workpiece.

Never hold the object that is being cut in your hands or across your legs. Secure the workpiece on
a stable surface. It is important to support the workpiece properly so that body contact is
minimised, the blade does not jam, and you do not lose control.

Hold the power tool by the insulated grips when working in areas where the tool may come into
contact with concealed electrical cables or its own power cord. In the event of contact with a live
cable, the metal parts of the tool will also become conductive and the user will receive an electric
shock.

Always use a fence or guide to obtain a straight cut when sawing. This makes the cut more precise
and reduces the risk of the blade jamming.

Always use blades with the correct size and shape of centre hole (rhomboidal or round). Blades
that do not fit properly on the tool will run eccentrically, which will reduce performance.

Never use damaged or incorrect washers or screws for the blade. Blade washers and screws are
specially designed for the tool to ensure optimum functionality and maximum safety.
Causes of kickback and ways to prevent it

Kickback can suddenly occur if the blade gets stuck, jams or is incorrectly adjusted. The saw kicks
back up from the workpiece towards the user.

If the blade jams, or gets caught in a cut that is squeezed together, it will lock and the power of the
motor can cause the saw to kickback towards the user.

If the blade is twisted, or comes out of alignment in the cut, the teeth on the back edge of the blade
can cut into the surface of the workpiece, so that the blade jerks out of the cut and kicks back
towards the user.
Kickback occurs during incorrect use of the tool and/or incorrect working methods or conditions, but can
be prevented by taking the following measures.
1.
Hold the tool firmly with both hands and hold your arms in a position that prevents kickback. Stand
to the side of the blade, not in line with it. Kickback can cause the tool to jerk backwards, but the
user can control this by taking the appropriate measures.
2. If the blade jams, or the sawing action is interrupted for any reason, release the power switch and
hold the saw still in the material until the blade has completely stopped. Never attempt to remove
the saw from the workpiece, or pull the saw back, while the blade is still moving
– otherwise
kickback can occur. Check and rectify the reason for the blade jamming.
3. Before restarting the saw in the workpiece, centre the blade in the cut and check that the teeth are
not gripping the material. If the saw blade jams it can slip or jump backwards from the workpiece
when the saw is restarted.
4. Support large boards to minimise the risk of kickback or the blade jamming. Large boards often sag
under their own weight. Supports must be placed under the board on both sides, close to the
cutting line and close to the edge of the board.
5. Do not use blunt or damaged blades. Poorly sharpened or incorrectly adjusted blades produce
narrow saw cuts, which generate excessive friction and cause the blade to jam or kick back.
6. The locking devices for the depth and angle of the blade must be tightened and secured before you
start sawing. If the blade is adjusted during the sawing there is a risk of the blade jamming or
kicking back.
7. Take extra care when plunge cutting in walls or other similar areas where you cannot see what lies
behind. The protruding blade may strike objects that can cause kickback.
