▶ Keep the power tool out of reach of children.
▶ Do not touch rotating parts. Switch the power tool on only after it is in position at the workpiece. Touching
rotating parts, especially rotating accessory tools, can result in injury.
▶ Grinding can produce hazardous grinding dust. Before starting work, check the hazard class of the dust
that will be produced by grinding operations. When working with the power tool, whenever possible use
a dust extractor with an officially approved protection class in compliance with the locally applicable dust
protection regulations.
▶ 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. 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. Use a dust extractor whenever possible. To
achieve a high level of dust collection, use a suitable dust extractor. If necessary, wear a respirator
appropriate for the type of dust generated. Make sure that the workplace is well ventilated. Comply
with national regulations applicable to the materials you will be working with.
▶ Before starting grinding work, carefully remove all protruding parts such as nails, screws, etc.
▶ Grinding can produce flying sparks. Make sure that no-one is endangered.
Power tool use and care
▶ Secure the workpiece. Use clamps or a vice to hold the workpiece in position. The workpiece is thus
held more securely than by hand and both hands remain free to operate the power tool.
▶ Always before starting work, and this also applies after each break, check that the accessory tool is
secure.
Electrical safety
▶ Before beginning work, check the working area (e.g. using a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present. External metal parts on the power tool can become
live, for example if you inadvertently damage electric wiring. This presents a serious risk of electric shock.
▶ Never disconnect the plug from the DPC 20 power conditioner while the DG 150 grinder is in operation
under load.
▶ Check the machine's supply cord at regular intervals and have it replaced by a qualified specialist if
found to be damaged. If the machine's supply cord is damaged it must be replaced with a specially
prepared and approved supply cord available from Hilti Customer Service. Check extension cords at
regular intervals and replace them if found to be damaged. Do not touch the supply cord or extension
cord if it is damaged while working. Disconnect the supply cord plug from the power outlet. Damaged
supply cords or extension cords present a risk of electric shock.
▶ Have dirtied or dusty power tools that are used frequently for working on conductive materials checked
at regular intervals by Hilti Service. Dust (especially dust from conductive materials) or dampness on the
surface of the power tool can, under unfavorable conditions, lead to electric shock.
Personal safety
▶ Make sure that the workplace is well ventilated. It is advisable to wear a filter class P2 dust mask.
▶ The diamond cup wheel, parts of the guard or the power tool (gear head) can become hot in use. To
avoid burns, do not touch these parts unless you are wearing gloves.
