Bosch GWS Professional 17-125 SB Manual Original página 31

Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Restart protection
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
To restart the tool, set the on/off switch (3) / (6) to the "off"
position and then switch the power tool on again.
Soft start
The electronic soft start limits the torque when the power
tool is switched on and enables a smooth start-up.
Note: If the power tool runs at full speed immediately after
being switched on, this means that the soft start and restart
protection mechanisms have failed. The power tool must be
sent to the after-sales service immediately; see the "After-
Sales Service and Application Service" section for ad-
dresses.
Constant Electronic control
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
Speed preselection
(GWS 14-125 S / GWS 17-125 S / GWS 17-125 TS / GWS 17-125 S INOX / GWS 17-150 S / GWS 17-125 SB /
GWS 17-125 PS / GWS 17-150 PS / GWS 17-125 PSB)
You can preselect the required speed using the speed preselection thumbwheel (5), even during operation, provided the dust

commended values.

Bosch Power Tools
Kickback control
If there is a sudden kickback in the power tool,
e.g. jamming in a separating cut, the power
supply to the motor will be interrupted elec-
tronically.
To restart the tool, set the on/off switch (3) / (6) to the "off"
position and then switch the power tool on again.
Drop control
(GWS 17-125 SB / GWS 17-125 PSB)
The integrated impact shutdown switches the
power tool off as soon as it hits the floor. To re-
start the tool, set the on/off switch (3) / (6) to

out brake. When the power tool is switched off
or the power supply is interrupted, the abras-
