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
▶ 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.
▶ 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.
