Please note before start-up
1. The electric supply must comply with the
data printed on the machine’s rating plate.
2. This machine is grounded (earthed).
3. Do not exert undue pressure on the machine.
This will not increase its performance. Just
position the bit and guide it into the hole.
Lubrication of chuck
The chuck is not incorporated in the lubricating
system of the machine. The drill bit connection
end, therefore, must be cleaned regularly and
lubricated sparingly with Hilti grease.
Start-up time at low temperatures
Start-up time can be reduced by jolting the drill
bit against the work surface when switching on.
Servicing: Electric tools comply with
respective safety regulations. Servicing
must, therefore, be carried out only by qual-
ified electrical specialists. For your safety,
only use original Hilti spare parts.
Operating:
Fig. 1: Insertion of drill bit
Turn chuck to the left (symbol ( )). Insert drill
bit in any position until resistance is felt. Then
turn it until it moves in farther. Turn chuck to
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
adjustment” position (symbol
) until
the lockbutton 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 and ensure that the forwards /
reverse switch is in the forwards position
(see fig. 6).
Fig. 6: Forwards / reverse switch
Forwards rotation: Move the lever to the left.
Reverse rotation: Move the lever to the right.
Fig. 7: Changing the chuck
Pull forward sleeve and completely remove
chuck. When attaching chuck, pull forward
sleeve and hold it there. Press chuck onto
guide tube as far as it will go. Release
sleeve. Turn chuck until steel balls snap into
place.
Note:
When a key-type chuck or 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 vibration it is rec-
ommended that the “drilling without ham-
mering action” position (fig. 3) is selected.
Fig. 8: Side handle / depth gauge
Unscrew side handle to release depth gauge.
Adjust depth gauge and retighten.
