Care And Maintenance - Hilti TE 6-A36 Operating Instructions Manual

7.2.1 Working at low temperatures
NOTE
The hammering mechanism works only when the power
tool has reached a minimum operating temperature.
Bring the drill bit briefly into contact with the base material
while allowing the power tool to run under no load until the
minimum operating temperature is reached. If necessary,
en
repeat this procedure until the hammering mechanism
begins to operate.
7.2.2 Forward / reverse
NOTE
The forward / reverse switch is used to select the direction
of rotation of the drive spindle. An interlock prevents
switching while the motor is running. The control switch
is locked when the forward / reverse switch is in the
middle position.
For forward rotation, push the forward / reverse switch
on the side of the power tool toward the chuck in the
direction of the arrow.
For reverse rotation, push the forward / reverse switch on
the side of the power tool toward the grip in the direction
of the arrow.
Bring the forward / reverse switch into the desired posi-
tion.
7.2.3 Drilling without hammering 10
1. Set the forward / reverse switch to the "forward"
position before beginning drilling.
2. Turn the function selector switch until it engages in
the "Drilling without hammering" position. Do not
operate the function selector switch while the motor
is running.
3. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
4. Fit the battery.
5. Position the power tool and drill bit at the point
where the hole is to be drilled.
6. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).

8 Care and maintenance

CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional start-
ing.
8.1 Care of insert tools
Clean off dirt and dust deposits adhering to the insert
tools and protect them from corrosion by wiping the
insert tools from time to time with an oil-soaked rag.
Check that the connection end of the insert tool is clean
and lightly greased. Clean it and grease it if necessary.

7. Press the control switch fully to continue drilling with
full power.
8. Adjust the pressure applied to the power tool ac-
cording to the material you are working on. This will
ensure the optimum rate of drilling progress.
7.2.4 Hammer drilling 11
1. Set the forward / reverse switch to the "forward"
position before beginning drilling.
2. Turn the function selector switch until it engages in
the "Hammer drilling" position. Do not operate the
function selector switch while the motor is running.
3. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
4. Fit the battery.
5. Position the power tool and drill bit at the point
where the hole is to be drilled.
6. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
7. Press the control switch fully to continue drilling with
full power.
8. Adjust the pressure applied to the power tool ac-
cording to the material you are working on. This will
ensure the optimum rate of drilling progress.
9. Reduce drilling speed shortly before breaking
through in order to avoid spalling.
7.2.5 Reading the charge status LED display on
Li‑ion batteries 12
NOTE
The charge status cannot be indicated while the power
tool is in operation. LED 1 blinks when the battery is
fully discharged or when it is too hot (temperature above
80°C). The battery must then be inserted in the charger.
If all 4 LEDs blink, this indicates that the power tool has
been overloaded or has overheated.
The Li-ion battery features a charge status LED display.
The charge status is indicated by the LEDs on the battery
during charging (please refer to the operating instructions
for the charger). When the battery is not in use, pressing
one of the battery release buttons or inserting the battery
into the power tool causes the battery charge status to
be displayed by the four LEDs for three seconds.
See section: 2.10 Li‑ion battery charge status
8.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use clean-
ing agents which contain silicone.
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
