▶
The product is not intended for use by debilitated persons who have received no special training. Keep
the product out of reach of children.
▶
Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some
examples are: lead or lead-based paints; brick, concrete and other masonry products, natural stone
and other products containing silicates; certain types of wood, such as oak, beech and chemically
treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and
bystanders by means of the hazard classification of the materials to be worked. Implement the necessary
measures to restrict exposure to a safe level, for example by the use of a dust collection system or by
the wearing of suitable respiratory protection. The general measures for reducing exposure include:
▶
working in an area that is well ventilated,
▶
avoidance of prolonged contact with dust,
▶
directing dust away from the face and body,
▶
wearing protective clothing and washing exposed areas of the skin with water and soap.
▶
The user and the other persons in the vicinity must wear suitable eye protection, a hard hat and ear
protection while the product is in use.
▶
Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed
accessories are secure.
▶
Keep the air vents clear at all times. Risk of burn injuries due to blocked air vents!
▶
Switch the product on only after you have brought it to the working position.
▶
Wait until the product stops completely before you lay it down.
▶
Wear protective gloves when changing the cut-off wheel. Touching the accessory tool can result in cuts
and burns.
▶
If the product detects operation beyond its limits or a discharged battery, there is a possibility that the
tool will no longer be braked by the motor.
Power tool use and care
▶
Grinding discs must be stored and handled carefully in accordance with the manufacturer’s instructions.
▶
Never use the product without the guard.
▶
Secure the workpiece. Use clamps or a bench vise to hold the workpiece in position. The workpiece is
thus held more securely than by hand and both hands remain free to operate the product.
▶
Do not use cut-off wheels for grinding.
▶
Tighten the accessory tool and flange securely. If the accessory tool and flange are not tightened
securely, the accessory tool may work loose from the arbor due to the braking effect of the motor after
switching off.
▶
Do not attach a belt hook to this product.
Electrical safety
▶
Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the product could give you an electric shock or cause an explosion if you
accidentally damage an electric cable or a gas or water pipe.
▶
Dirty or dusty products that have been used frequently for work on conductive materials should be
checked at regular intervals by Hilti Service. Dust (especially dust from conductive materials) or
dampness adhering to the surface of the power tool may, under unfavorable conditions, lead to electric
shock.
Workplace
▶
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.
