Possible Applications - Hilti UH 700 Mode D'emploi

6. Remove the chuck key.

7.2.3 Possible applications

CAUTION
In accordance with the applications for which it is de-
signed, the power tool produces a high torque. Always
use the side handle and hold the power tool with both
hands. The user must be prepared for sudden sticking
and stalling of the insert tool.
CAUTION
If stalling occurs, switch off the motor immediately. The
power tool may suffer damage if stalled for longer than
2-3 seconds.
CAUTION
Do not operate the function selector switch while the
motor is running.
NOTE
The forward / reverse switch must be set to the "forward"
position.
7.2.3.1 Hammer drilling 8
1. Turn the function selector switch to the "Hammer
drilling" position until it engages. It may be necessary
to turn the drive spindle slightly.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
4. Position the power tool and drill bit at the point
where the hole is to be drilled.
NOTE We recommend use of the dust shield for
overhead drilling. This will help to reduce the amount
of dust entering the chuck.
5. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
6. Press the control switch fully to continue working at
full power.
NOTE With this hammer drill, drilling performance
depends on the amount of pressure applied to it.
7. To avoid material breaking away at the rear surface
when drilling through-holes, reduce drilling speed
and pressure shortly before breaking through.
7.2.3.2 Dust removal (TE DRS‑S) 9
The DRS dust removal system is attached to the side
handle / depth gauge. Drilling dust and fragments can
then be removed by a vacuum cleaner. For further infor-
mation on operation and use of the dust removal system,
please refer to the separate operating instructions for the
TE DRS‑S.
7.2.3.3 Rotary drilling, 1st and 2nd gear 10
1. Turn the function selector switch to the 1st or 2nd
gear rotary drilling position until it engages. It may
be necessary to turn the drive spindle slightly.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
4. Position the power tool and drill bit at the point
where the hole is to be drilled.
5. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
6. Press the control switch fully to continue working at
full power.
7. 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.
7.2.3.4 Mixing
1. Turn the function selector switch to the 1st gear
rotary drilling position until it engages. It may be
necessary to turn the drive spindle slightly.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
4. Position the mixing paddle in the container holding
the substance to be mixed.
5. To begin mixing, press the control switch slowly.
6. Press the control switch fully to continue working at
full power.
7. Guide the mixing paddle carefully in order to avoid
splashing and spillage.
7.2.3.5 Screwdriving
NOTE
Set the forward / reverse switch to suit the screwdriving
operation to be carried out.
1. Turn the function selector switch to the 1st or 2nd
gear rotary drilling position until it engages. It may
be necessary to turn the drive spindle slightly.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
4. Press the control switch slowly until the screw grips
and is guided by the material into which it is being
driven.
5. Continue pressing the control switch, applying
power appropriate to the material you are working
on.
6. Reduce speed toward the end of the screwdriving
operation in order to avoid damage.
7.2.4 Control switch with electronic speed control
The speed of the power tool can be varied continuously
up to maximum speed by slowly increasing pressure on
the control switch.
7.2.5 Lockbutton for sustained operation
The lockbutton for sustained operation is used to lock
the control switch in the "on" position. The motor then
runs constantly at full speed.
7.2.5.1 Switching on in sustained operating
mode 11
1. Press the control switch and hold it in this position.
2. Press the lockbutton and hold it in this position.
3. Release the control switch.
