1.
Clean and grease the shank of the bit. Special grease can be obtained as
accessory
2.
Insert the SDS-plus drill bit.
3.
Make the following settings
hammer drilling
forward rotation
4.
Apply the machine to the working material when switched off, then switch the
machine on, activate the pneumatic hammer mechanism with short pressure of the
machine against the material, and continue to work applying light pressure.
Exerting greater pressure does not increase the machine’s effectiveness!
When hammer-drilling overhead, use the dust cap (accessory).
Take the drill out of the hole from time to time to remove dust.
Switch to percussion-drilling for concrete, hard bricks and tiles, stone, hard cement,
and marble (but not when drilling the surface of marble).
For tiles, paving-stones, soft bricks and tiles, soft cement, breeze-block and plaster,
switch to normal drilling.
Use percussion carbide tipped masonry drill-bits.
When drilling a hard, smooth surface (e.g. tiles), cover the point to be drilled with
adhesive tape in order to prevent the drill bit tip from skidding.
1.
Fit the mounting shaft into the
drill-hammer chuck as described above.
2.
If the mounting shaft has an adjustable
metal ring (i.e. if included in the set), the
longitudinal play of the SDS-plus mounting
can be compensated for. To do this, turn
the metal ring of the mounting shaft
anti-clockwise as far as it will go.
Drill chucks with 1/2” x 20 UNF mounting
threads can be screwed onto the mounting
shaft. Screwdriver bits can be inserted directly into of the mounting shaft.
When using the adaptors always turn the hammer function off.
*Not included in standard equipment, available as an accessory.
If the carbon brushes cut-out or the hammer capacity declines please contact your
authorized Milwaukee service station. This will ensure long service life as well as
constant readiness for working of the machine.
The location of your nearest service station is shown in our “Service adresses” leaflet
attached to each product.
The ventilation slots of the machine must be kept clear at all times.
Use only Milwaukee accessories and spare parts. Should components need to be
exchanged which have not been described, please contact one of our Milwaukee
service agents (see our list of guarantee/service addresses).
If needed, an exploded view of the tool can be ordered. Please state the ten–digit
No. as well as the machine type printed on the label and order the drawing at your
local service agents or directly at: Atlas Copco Electric Tools GmbH, Postfach 320,
D–71361 Winnenden.
