Switching On And Off - FISCHER FSS 18 V 600 Manual De Instrucciones

6.2 Setting the direction of rotation, engaging the
transporting safety device (switch-on lock)
Do not actuate the rotation selector switch
or engage the transportation lock (2) unless
EN
the motor has stopped completely.
R = Right rotation set (insert screws)
L = Left rotation set (remove screws)
0 = Central position: transportation lock
setting (switch-on lock)

6.3 Switching on and off

Switching on: Press the trigger switch (3).
Switching off: Release the trigger switch (3).
6.4 Speed / Tightening torque
The speed and tightening torque are
connected directly. The lower the speed,
the lower the tightening torque.
The speed and tightening torque can be
adjusted steplessly by pressing the trigger
(3) firmly or lightly, thus adapting to working
conditions.
You can use the setting wheel (5) on the
FSS 18V 400 BL to adjust the rotational
speed and tightening torque (12 stages).
Recommendation: Determine the correct
setting by carrying out trial screwdriving.
6.5 Changing screwdriving bits
Inserting screwdriving bit: Fit the tool on the
square attachment (1) until the limit stop.
Removing screwdriving bit: Pull the tool from
the square attachment (1).
The screwdriving bit used must match
the screw.
Damaged screwdriving bits must not
be used.

7. Use
Mount the machine on the screw, ensuring it is
aligned straight.
The screwdriving process has two elements:
Inserting the screw and tightening the screw
with the percussion mechanism.
The tightening torque depends on the impact
duration.
T a
(Nm)
With an impact duration of approx. 5 seconds,
the maximum tightening torque has been
reached.
The torque curve depends on the type of
application:
With a hard screwdriving application
(screwcouplings in hard material such as
metal), maximum tightening torque is already
reached after a short impact duration (a).
With a soft screwdriving application
(screwcouplings in soft material such as
wood), a longer impact duration (b) is required.
Recommendation: Determine the correct
impact duration by carrying out trial
screwdriving.
Caution! With small screws, maximum torque
can be reached even below an impact duration
of 0.5 seconds.
- This is why the duration of the screwdriving
process must be monitored exactly.
- Adjust the tightening torque by pressing
firmly or lightly on the trigger (3), ensuring
that the screw is not damaged or that the
screw head does not tear off.
