Working With The Power Tool; Rough Grinding; Care And Maintenance - Hilti DCG 230-DB Manual De Instrucciones

1. Disconnect the supply cord plug from the power
outlet.
2. Release the locking lever by pulling it back.
3. Pivot the grip to the left or right as far as it will go.
4. Secure the grip in position by closing the locking
lever.
NOTE The power tool cannot be switched on as
long as the grip is not locked in one of the three
possible positions.

7.4 Working with the power tool

NOTE
Apply only moderate pressure.
NOTE
The direction in which the cut is made is important. The
disc must always cut in counter-rotating mode. Failure
to observe this point presents a risk of the cutting disc
being forced uncontrollably out of the kerf.
NOTE
Special discs should be used for working on non-ferrous
metals (e.g. aluminium).

8 Care and maintenance

CAUTION
Disconnect the mains plug from the power outlet.
8.1 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 (RCD)
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
NOTE
When the power tool is used in conjunction with the DC-
EX hood and a suitable vacuum cleaner, the volume of
dust emitted can be greatly reduced.
NOTE
The cutting disc may overheat and suffer damage when
cutting very hard mineral materials with a high hard
pebble content. A trail of sparks right round the circum-
ference 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.
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).

7.5 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.
electrical safety of the power tool. Always keep the grip
surfaces of the power tool free from oil and grease. Do
not use cleaning agents which contain silicone.
8.2 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 specialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly.
8.3 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.
