Cleaning the drill bit connection end:
The chuck is not included in the machine’s
lubrification system. The drill bit connect-
ion end should therefore be cleaned at
regular intervals and sprayed sparingly
with Hilti lubricant spray, which is available
as an accessory.
Electronic switch:
The TE5A’s electronic switch is equipped
with a temperature sensor designed to
protect the switch from overheating. The
temperature sensor can become activ-
ated within the switch’s speed regulation
range (from the switch-on point up to just
below maximum speed). When the sensor
is activated the motor runs with a constant
low speed or, when a load is applied, may
stop completely (the machine behaves in
a similar way when the battery is almost
fully discharged).
The temperature sensor can be deactiv-
ated by depressing the switch completely
(full speed). The TE5A will then run again
normally.
Operation:
Fig. 1: Inserting the TE-C drill bit
Turn the chuck locking sleeve towards the
( )
symbol and insert the drill bit, turning
it until the drive grooves engage and it can
be pushed in fully. Lock the chuck by turn-
ing the locking sleeve towards the
()
symbol.
Fig. 2: Hammer drilling/rotary drilling
Hammer drilling
in concrete, masonry
and natural stone: With the machine run-
ning slowly (switch depressed only slight-
ly), move the selection lever to the ham-
mer drilling position (hammer symbol).
Rotary drilling
in wood and steel: With
the machine running slowly ( switch de-
pressed only slightly), move the selection
lever to the rotary drilling position (drill bit
symbol). When the lever is in this position,
only the rotary action is transmitted to the
drill bit.
Fig. 3: Left-hand rotation
The direction of rotation can be reserved
by operating the reserving switch. The
reversing switch must not be operated
while the machine is running – damage to
the mechanism could otherwise result.
Fig. 4: 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.
Fig. 5: Changing the chuck
Pull the sleeve forwards to remove the
chuck as a complete unit. When refitting
the chuck, pull the sleeve forwards and
hold it in position. Slide the chuck onto the
guide as far as it will go and release the
sleeve. Rotate the chuck until the sleeve
snaps back into position.
Note: When the key-type chuck or quick-
release chuck is fitted, the hammering
action cuts out automatically (rotary drilling
only). To insert a drill bit with a cylindrical
connection end, open the key-type chuck
to the required diameter, insert the drill bit
as far as it will go and tighten the chuck
using the key.
Fig. 6: Interface for dust removal mo-
dule
All TE5A battery-powered rotary
hammers can be equipped with the
TE5-DRS dust removal module, which
can be attached to the battery-pow-
ered rotary hammer quickly and with-
out the use of tools.
The cover on the
base of the
TE5A
(at the motor endcap)
must be opened before attaching the
dust removal module!
