Operation - Hilti ST1800 Mode D'emploi

– The operating voltage must remain within +5% and –
15% of the rated voltage at all times.
– Permissible frequency: 50–60 Hz; never above 65 Hz.
– The equipment must be fitted with an automatic volt-
age regulator with starting compensation.

6. Operation

Use clamps or a vice to secure the workpiece.
The workpiece is thus held more securely than
by hand and both hands remain free to oper-
ate the tool.
The screwdriving procedure may
G
cause the material to splinter.
Splintering material may injure the
G
eyes.
Wear eye protection.

6.1 Setting forward / reverse rotation
The forward / reverse selector pushbutton can be used
to select the desired direction of rotation. An interlock
prevents operation of the pushbutton while the motor
is running.
– Pushbutton moved to the right (as seen with tool in
working position) = forwards rotation.
– Pushbutton moved to the left (as seen with tool in
working position) = reverse rotation.
6.2 Torque adjustment
1. Turn the torque adjusting ring to the desired torque
setting (positions 1–18, see section 4.2 for informa-
tion on applications and screw types).
6.3 Switching on / off
1. Plug the supply cord into the electric socket.
2. Press the control switch slowly. The speed of the tool
can thus be varied between 0 and maximum speed.
6.4 Lockbutton for sustained operation
Use of the lockbutton permits sustained operation (motor
running constantly) without need to maintain pressure
on the control switch.
6.4.1 Switching on in sustained operating mode
1. Press the control switch as far as it will go.
2. Press the lockbutton while maintaining pressure on
the control switch and then release the control switch.
6.4.2 Switching off when running in sustained mode
1. Press the control switch. The lockbutton returns to
its original position.

-CAUTION-
Never operate other tools or appliances from the
generator or transformer at the same time. Switching
other tools or appliances off and on can result in sudden
overvoltage or undervoltage which may cause damage
to the tool.
6.5 Fitting the depth gauge
1. Unplug the supply cord from the electric socket.
2. Insert the tip of a screwdriver in the gap between the
tool and the protective sleeve. Pry the protective sleeve
away from the tool by turning the screwdriver.
3. Pull the protective sleeve off toward the front end of
the tool.
4. Push the depth gauge onto the tool from the front.
6.6 Depth gauge adjustment
The depth gauge is used when driving screws with sealing
washers.
Use a depth gauge suitable for the applicable sealing
washer diameter (accessory).
The depth gauge can be adjusted to ensure correct com-
pression of the sealing washer under the head of the
screw.
6.6.1 Adjusting the depth gauge
To decrease compression of sealing washer
1. Turn the depth gauge to the right (II).
To increase compression of sealing washer
1. Turn the depth gauge to the left. Compression of the
screw seal is increased (± 0.25 mm /
stop) (III).
6.7 Removing the depth gauge
1. Pull the depth gauge off the tool toward the front.
6.8 Changing bits
The chuck is equipped with a
size is standardized (DIN 3126/ ISO 1173).
1. Pull the depth gauge off the tool toward the front.
2. Pull the sleeve to the rear and hold it in this position.
3. The bit can then be pulled out or a different bit inserted.
4. Release the sleeve and allow it to return to its origi-
nal position.
5. Refit the depth gauge to the tool.
6.9 Removing a previously driven screw
1. Pull the depth gauge off the tool toward the front.
2. Bring the forward / reverse pushbutton into the "reverse"
position.
3. The tool can now be used to remove the screw.
