Care And Maintenance - Hilti TE 1 Original Operating Instructions

7.1.2 Fitting the insert tool 4
1. Disconnect the supply cord plug from the power
outlet.
2. Check that the connection end of the insert tool is
clean and lightly greased. Clean it and grease it if
necessary.
3. Check that the sealing lip of the dust shield is clean
and in good condition. Clean the dust shield if ne-
cessary or replace it if the sealing lip is found to be
damaged (please refer to the "Care and mainten-
ance" section).
4. Push the insert tool into the chuck and rotate it while
applying slight pressure until it engages in the guide
grooves.
5. Push the insert tool further into the chuck until it is
heard to engage.
6. Check that the insert tool has engaged correctly by
pulling it.
7.1.3 Removing the insert tool 5
1. Disconnect the supply cord plug from the power
outlet.
2. Open the chuck by pulling back the chuck release
sleeve.
3. Pull the insert tool out of the chuck.
7.2 Operation
CAUTION
Working on the material may cause it to splinter. Wear
eye protection and protective gloves. Wear breathing
protection if no dust removal system is used. Splin-
tering material presents a risk of injury to the eyes and
body.

8 Care and maintenance

CAUTION
Disconnect the mains plug from the power outlet.
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.
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.
CAUTION
The work generates noise. Wear ear protectors. Expos-
ure to noise can cause hearing loss.
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,
repeat this procedure until the hammering mechanism
begins to operate.
7.2.2 Hammer drilling
1. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
2. Plug the supply cord into the power outlet.
3. Position the power tool and drill bit at the point
where the hole is to be drilled.
4. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
5. Press the control switch fully to continue drilling with
full power.
6. Do not apply excessive pressure. This will not in-
crease the power tool's hammering performance.
Lower pressure extends the life of the insert tool.
7. Reduce drilling speed shortly before breaking
through in order to avoid spalling.
7.2.3 Forward / reverse 6
CAUTION
Do not operate the forward / reverse switch while the
motor is running.
Move the forward/reverse switch to the "Forward" or
"Reverse" position.
Never operate the power tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Do not permit foreign objects to enter the
interior of the power tool. Clean the outside of the power
tool at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect the
electrical safety of the power tool.
8.3 Cleaning or replacing the dust shield
Clean the dust shield on the chuck with a dry, clean
cloth at regular intervals. Clean the sealing lip by wiping it
carefully and then grease it again lightly with Hilti grease.
It is essential that the dust shield is replaced if the sealing
lip is found to be damaged. Pull the chuck sleeve back,
hold it securely in this position and remove the dust
shield. Clean the area of the chuck in contact with dust
