▶ Do not use accessories not specifically intended and recommended for this power tool by the tool
manufacturer. The fact that an accessory can be attached to your power tool does not necessarily
mean that it can be used in safety.
▶ The rated speed of the accessory must be at least equal to the maximum speed marked on the
power tool. Accessories running faster than their rated speed can disintegrate and fly apart.
▶ The outside diameter and the thickness of the accessory tool must be within the ranges stated for
your power tool. Incorrectly sized accessory tools cannot be adequately guarded or controlled.
▶ Accessory tools with a threaded insert must match the thread of the arbor. Flange-mounted
accessory tools must have a hole diameter matching the mandrel diameter of the flange. Accessory
tools not correctly fixed to the power tool rotate unevenly, vibrate excessively and can cause control of
the tool to be lost.
▶ Do not use damaged accessory tools. Always check accessory tools before use. Check abrasive
wheels for chipping and cracks. Check grinding discs for cracks and heavy wear and tear, and check
wire brushes for loose or broken wires.
▶ If power tool or accessory is dropped, inspect for damage or install an undamaged accessory.
After inspecting and installing an accessory tool, position yourself and bystanders away from the plane
of the rotating tool and run the power tool at maximum no-load speed for one minute. If an accessory
tool has been damaged it will normally break during this test period.
▶ Wear personal protective equipment. Wear a face shield, eye protection or safety goggles, as
appropriate to the application.
▶ As appropriate, wear a dust mask, ear defenders, protective gloves or a workshop apron to keep
off abrasive particles and particles of workpiece material. Make sure your eyes are protected against
the flying debris created by various machining 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.
▶ 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 the immediate area of operation.
▶ Hold the power tool by the insulated gripping surfaces only, when carrying out work in which the
accessory tool can come into contact with concealed wiring. If the accessory tool comes into contact
with a live wire, metal parts of the power tool can also become live, causing the operator to receive an
electric shock.
▶ Never lay the power tool down before the accessory tool has come to a complete stop. If the
rotating accessory tool were allowed to touch the surface on which you are going to place the power
tool, you could lose control of the power tool.
▶ Never start the power tool while carrying it around. Your clothing could be snagged by the rotating
accessory tool, pulling the accessory tool into your body.
▶ Clean the ventilation slots of the power tool at regular intervals. The motor's fan draws dust into the
housing and a build-up of metallic dust can cause electrical hazards.
▶ Do not operate the power tool near flammable materials. Sparks could ignite these materials.
Kickback and the appropriate safety instructions
WARNING! Snagging or jamming brings the rotating accessory tool to an abrupt stop. If this
happens the power tool whips round in the direction opposite to the accessory tool's direction of rotation,
the grinding disc can catch and break out or cause a kickback.
By adopting suitable precautionary measures the operator can control the kickback and reaction forces:
▶ Maintain a firm grip on the power tool and position your body and arms to absorb kickback forces.
▶ Always use the auxiliary handle, if provided, for maximum control over kickback forces or torque
reaction during start-up.
▶ Always keep your hand well clear of the rotating accessory tool. Kickback could cause the accessory
tool to pass across your hand.
▶ Keep your body clear of where the power tool will move if kickback occurs. Kickback will propel the
power tool in the direction opposite to the wheel's direction of rotation at the point of snagging.
▶ Exercise special care when working at corners, sharp edges, etc. Avoid allowing the accessory
tool to bounce off or jam in the workpiece. The rotating accessory tool has a tendency to jam at
corners and sharp edges, or if it bounces off the workpiece. This causes loss of control or kickback.
▶ Do not attach a saw chain, woodcarving blade or toothed saw blade. Such blades create frequent
kickback and loss of control.
