Operation - Hilti SFC 22 A Manual De Instrucciones

Pull the battery out of the locked position (working posi-
tion) and move it into the first latching position (transport

Observe national and international transport regulations
when shipping batteries (transportation by road, rail, sea
or air).

6 Operation

CAUTION
The tool may get hot during use. Wear protective gloves.
CAUTION
When drilling and screwdriving, the grip of the tool
may be deflected laterally (the tool tends to pivot
about its own axis).
CAUTION
To avoid injuries caused by the insert tool, wear
protective gloves when changing insert tools.
DANGER
Set the forward / reverse switch to the middle position
or remove the battery from the power tool.
6.1 Setting forward or reverse rotation 5
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. Push the forward / reverse switch to
the right (power tool held in working direction) to select
forward rotation. Push the forward / reverse switch to
the left (power tool held in working direction) to select
reverse rotation.
6.2 Speed selection using the 2-speed gear
selector switch 6
WARNING
Large and heavy insert tools must only be operated
in first gear. There is otherwise a risk that the tool will be
damaged when it is switched off or, under unfavorable
conditions, the chuck might be detached.
NOTE
The mechanical 2-speed gear selector switch can be
used to set the speed range required. Speed with a fully-
charged battery. SFC 14‑A: 1st gear: 0‑500 /min., 2nd
gear: 0‑1700 /min. SFC 22‑A: 1st gear: 0‑600 /min., 2nd
gear: 0‑1800 /min.

5.5 Belt hook 4
CAUTION
Check that the belt hook is fitted securely before
beginning work.
The belt hook allows the power tool to be attached to a
belt worn by the operator. The belt hook can also be fitted
to the other side of the power tool for use by left-handed
persons.
1. Remove the battery from the power tool.
2. Fit the mounting plate into the guides provided.
3. Secure the belt hook with the two screws.
6.3 Switching on / off
Speed of rotation can be controlled smoothly up to max-
imum speed by pressing the control switch slowly.
6.4 Fitting the drill bit
1. Check that the connection end of the drill bit is
clean. Clean the connection end if necessary.
2. Insert the drill bit in the keyless chuck and then
turn the chuck firmly by hand until several clicks are
heard.
3. Check that the drill bit is held securely.
6.5 Removing the drill bit
1. Open the keyless chuck.
2. Pull the insert tool out of the chuck.
6.6 Drilling
CAUTION
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 operate the power tool.
1. Turn the torque and operating mode setting ring to
the drilling symbol.
2. Move the forward / reverse switch to the "Forward"
position.
6.7 Screwdriving
6.7.1 Fitting the bit holder / bit
1. Open the keyless chuck.
2. Insert the bit adapter in the keyless chuck and then
turn the chuck firmly by hand until tight.
3. Check that the bit adapter is held securely (check
by pulling).
4. Fit the bit in the bit holder.
6.7.2 Screwdriving
1. Select the torque function on the setting ring for
torque and drilling.
