Additional safety warnings specific for abrasive cutting-off operations:
▶
Do not "jam" the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive
depth of cut.
Overstressing the wheel increases the loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or wheel breakage.
▶
Do not position your body in line with and behind the rotating wheel.
When the wheel, at the point of
operation, is moving away from your body, the possible kickback may propel the spinning wheel and the
power tool directly at you.
▶
When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur.
Investigate
and take corrective action to eliminate the cause of wheel binding.
▶
Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully
re-enter the cut.
The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
▶
Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece
near the line of cut and near the edge of the workpiece on both sides of the wheel.
▶
Use extra caution when making a "pocket cut" into existing walls or other blind areas.
The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
2.1.3 Additional safety instructions
Personal safety
▶
Use the tool only when it is in technically faultless condition.
▶
Never tamper with or modify the tool in any way.
▶
Always hold the power tool with both hands on the grips provided. Keep the grips clean and dry.
▶
Avoid touching 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.
▶
Take breaks between working 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.
▶
Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking
through. Pieces of debris could drop out and / or fall down and injure other persons.
▶
Slits cut in load-bearing walls of buildings or other structures may influence the statics of the structure,
especially when steel reinforcing bars or load-bearing components are cut through. Consult the
responsible structural engineer, architect or person in charge of the building project before beginning the
work.
▶
Before beginning the work, check the hazard classification of the dust that will be produced. Use an
industrial vacuum cleaner with an officially approved protection classification in compliance with locally
applicable dust protection regulations.
▶
Use a dust removal system and suitable vacuum cleaner whenever possible. Dust from materials, such
as paint containing lead, some wood species, concrete/masonry/stone containing silica, and minerals as
well as metal, may be harmful.
▶
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 may cause allergic reactions and/or
respiratory or other diseases to the operator or bystanders. Certain kinds of dust are classified as
carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning
(chromate, wood preservative). Material containing asbestos may be handled only by specialists.
▶
To reduce the risk of injury, use only genuine
Hilti
accessories and accessory tools.
▶
Observe the 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 may give you an electric shock if you damage an electric cable
accidentally.
▶
Do not touch the supply cord or extension cord if damaged while working. Disconnect the supply cord
plug from the power outlet. Check the tool’s supply cord at regular intervals and have it replaced by
Hilti
Service if damage is found. Check extension cords at regular intervals and replace them if found to be
damaged.
