Please note before start-up
When in operation, the machine should be held
securely with both hands on the grips provided.
Always ensure that you work from a secure
stance.
1. The electric supply must comply with the
data printed on the machine’s rating plate.
2. Do not exert undue pressure on the machine.
This will not increase its performance. Just
position the bit and guide it.
Read the enclosed general safety rules.
Lubrication of chuck
The chuck is not incorporated in the lubricating
system of the machine. The drill bit connection
end must be cleaned regularly and lubricated.
Regularly with a small amount of Hilti grease.
Note: The use of TE-C chisels is not recom-
mended.
Operating:
Fig. 1: Insertion of drill bit
Turn chuck to the left (symbol ( )). Insert the
shank of the drill bit into the drill chuck. While
pushing in the bit rotate it until it moves farther
into the chuck. Turn chuck to the right and lock
drill bit in place (symbol ( )).
Fig. 2: Rotary hammer drilling
Rotary hammer drilling in concrete, masonry
and natural stone. Press the red lockbutton on
the switching lever. Turn the switching lever to
the “rotary hammer drilling” position (symbol
) until the lockbutton engages.
Fig. 3: Drilling without hammering action
Press the red lockbutton on the switching lever.
Turn the switching lever to the “rotary drilling”
position (symbol
) until the lockbutton
engages. In this position, the insert tool simply
rotates with no hammering action.
Fig. 4: Chisel adjustment
Press the red lockbutton on the switching lever.
Turn the switching lever to the “chisel adjust-
ment” position (symbol
) until the lockbut-
ton engages.
Fig. 5: Chiselling function
Secure the chisel in the desired position and
select the chiselling function. Press the red
lockbutton on the switching lever. Turn the
switching lever to the “chiselling” position
(symbol
) until the lockbutton engages.
Fig. 6: Changing the chuck
Turn chuck to the left (symbol ( )). Pull the
sleeve forward and completely remove chuck.
When attaching chuck, pull the sleeve forward
and hold it there. Slide chuck onto guide tube
as far as it will go. Release sleeve. Turn chuck
until steel balls snap into place.
Note:
When a quick-release chuck is used, the
hammering action is not transmitted to the
insert tool (drilling without hammering action).
However, for smoother running with less vibra-
tion it is recommended that the “drilling without
hammering action” position (fig. 3) is selected.
Fig. 7: Side handle / depth gauge
The side handle can be pivoted and clamped in
any desired position. Release the side handle
by turning the grip counter clockwise, set the
desired drilling depth with the depth gauge and
then lock the side handle in position by turning
the grip in a clockwise direction.
