Hilti SCO 6-A22 Original Operating Instructions page 20

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.
2.2 Additional safety instructions for cut-out tools
▶ Use clamps or another some other practical way to secure and support the workpiece to a stable
platform. Holding the work by your hand or against the body leaves it unstable and may lead to loss of
control.
Personal safety
▶ Use the tool only when it is in perfect working order.
▶ Never tamper with or modify the tool in any way.
▶ Always hold the tool firmly with both hands on the insulated grips provided. Keep the grips clean and
dry.
▶ Do not touch rotating parts – risk of injury!
▶ Wear suitable protective glasses, a hard hat, ear protection, protective gloves and light respiratory
protection while using the power tool.
▶ Do not look directly into the light source (LEDs) of the cut-out tool and do not aim the beam at other
persons' faces. Risk of dazzling or eye damage.
▶ Never touch the clamping nut or collet when the accessory tool gets stuck and stalls.
▶ Take breaks and do physical exercises to improve the blood circulation in your fingers. Exposure to
vibration during long periods of work can lead to disorders of the blood vessels and nervous system in
the fingers, hands and wrists.
▶ The power tool is not intended for use by debilitated persons who have received no special training.
Keep the power tool out of reach of children.
▶ If work involves break-through, always secure the area on the side opposite where the work is carried
out. Pieces of debris could drop out and/or fall down and injure other persons.
▶ Slits cut into load-bearing walls or other structures can influence the statics of the structure, especially
when reinforcing bars or load-bearing components are cut. Consult the responsible structural engineer,
architect or person in charge of the building project before starting work.
▶ Before switching on the tool, check that the collet is fitted and that the clamping nut is tightened.
▶ Use only accessory tools with the correct shank diameter and of a type suitable for the speed of the
power tool.
▶ Check that accessory tools are compatible with the power tool's chuck/drive system and that they are
fitted and secured correctly.
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use
an industrial vacuum cleaner with an officially approved protection class in compliance with the locally
applicable dust protection regulations.
▶ Use a dust removal system and suitable mobile dust extractor whenever possible. Dust from materials
such as lead-based paint, certain types of wood and concrete/masonry/stone containing quartz, minerals
or metal can be harmful to health.
▶ Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust can cause allergic reactions and/or
respiratory or other diseases among operators or bystanders. Certain kinds of dust such as oakwood
and beechwood dust are classified as carcinogenic, especially in conjunction with additives for wood
conditioning (chromate, wood preservative). Only specialists are permitted to handle material containing
asbestos.
▶ To avoid risk of injury, use only genuine Hilti accessories and accessory tools.
▶ Comply with national health and safety requirements.
Electrical safety
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the power tool can become live, presenting a risk of electric shock, if you
accidentally damage an electric cable.
Power tool use and care
▶ Immediately switch off the power tool if the accessory tool jams. The power tool might twist off-line.
▶ Wait until the power tool stops completely before you lay it down.
