Cut-Off Machine Safety Warnings - Hilti DCH 150­SL Manual De Usario

▶ Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking
into account the working conditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a hazardous situation.
Service
▶ Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.

Cut-off machine safety warnings

▶ The guard provided with the tool must be securely attached to the power tool and positioned for
maximum safety, so the least amount of wheel is exposed towards the operator. Position yourself
and bystanders away from the plane of the rotating wheel. The guard helps to protect operator from
broken wheel fragments and accidental contact with wheel.
▶ Use only bonded reinforced or diamond cut-off wheels for your power tool. Just because an
accessory can be attached to your power tool, it does not assure safe operation.
▶ 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 break and fly apart.
▶ Wheels must be used only for recommended applications. For example: do not grind with the side
of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
▶ 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.
▶ Do not use worn down reinforced wheels from larger power tools. Wheels intended for a larger
power tool are not suitable for the higher speed of a smaller tool and may burst.
▶ 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.
▶ 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.
▶ 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.
▶ Wear personal protective equipment. Depending on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and shop 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.
▶ 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 wheel may fly away and cause
injury beyond immediate area of operation.
▶ Hold the power tool by insulated gripping surfaces only, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could give the operator an electric
shock.
▶ Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning wheel.
▶ Never lay the power tool down until the accessory has come to a complete stop. The spinning
wheel may grab the surface and pull the power tool out of your control.
▶ 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.
▶ 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.
▶ Do not operate the power tool near flammable materials. Sparks could ignite these materials.
▶ Do not use accessories that require liquid coolants. Using water or other liquid coolants may result
in electrocution or shock.
