Rough Grinding; Care And Maintenance - Hilti DAG700-P Manual De Instrucciones

NOTE
Special discs should be used for working on non-
ferrous metals (e.g. aluminium).
NOTE
The cutting disc may overheat and suffer damage
en
when cutting very hard mineral materials with a high
hard pebble content. A trail of sparks right round the
circumference of the cutting disc is a sure indication
of this. In this case, the cutting operation should be
interrupted and the cutting disc allowed to cool by
running the power tool under no load for a short time.

7. Care and maintenance

CAUTION
Disconnect the mains plug from the power outlet.
7.1 Care of the power tool
DANGER
Under extreme conditions, when used for working
on metal, conductive dust may accumulate inside
the tool. This may have an adverse effect on the
tool's protective insulation. Under such conditions,
the tool should be plugged into a ground fault
circuit interrupter (GFCI) and use of a stationary
dust removal system and frequent cleaning of the
tool's cooling air slots is recommended.
The outer casing of the power tool is made from
impact-resistant plastic. Sections of the grip are made
from a synthetic rubber material.
Never operate the power tool when the ventilation
slots are blocked. Clean the ventilation slots carefully
using a dry brush. Do not permit foreign objects to
enter the interior of the power tool. Clean the outside
of the power tool at regular intervals with a slightly
damp cloth. Do not use a spray, steam pressure
cleaning equipment or running water for cleaning.
This may negatively affect the electrical safety of the

NOTE
A decrease in the rate of cutting progress may be an
indication of blunt/dull segments. The segments can
be resharpened by making a few cuts in an abrasive
material (Hilti sharpening plate or sand-lime block).

6.3 Rough grinding

CAUTION
Never use cutting discs for grinding.
When rough grinding, maximum efficiency is
achieved when the power tool is held with the disc
at an angle of 30° to the work surface. Excessive
pressure applied while grinding will damage the
power tool, increase disc wear and reduce grinding
efficiency.
power tool. Always keep the grip surfaces of the
power tool free from oil and grease. Do not use
cleaning agents which contain silicone.
7.2 Maintenance
WARNING
Do not operate the power tool if parts are damaged,
if the electronic control unit is defective or when the
controls do not function faultlessly. Have the power
tool repaired by Hilti Service.
WARNING
Repairs to the electrical section of the power tool
may be carried out only by trained electrical spe-
cialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly.
7.3 Checking the power tool after care and
maintenance
After carrying out care and maintenance work on
the power tool, check that all protective and safety
devices are fitted and that they function faultlessly.
