OBJ_BUCH-1961-003.book Page 23 Wednesday, November 27, 2013 3:12 PM
When operating the machine with power from mobile genera-
tors that do not have sufficient reserve capacity or are not
equipped with suitable voltage control with starting current
amplification, loss of performance or untypical behavior can
occur upon switching on.
Please observe the suitability of the power generator being
used, particularly with regard to the mains voltage and fre-
quency.
Switching On and Off
PWS 1000.. (see figure A)
To start the power tool, push the On/Off switch 3 forwards.
To switch off the machine, release the On/Off switch 3.
PWS 1300.. (see figure B)
To start the power tool, press the On/Off switch 3 forward
and then down.
To lock the On/Off switch 3, press the On/Off switch 3 down
at the front until it latches.
To switch off the power tool, release the On/Off switch 3 or,
if it is locked, briefly push down the back of the On/Off switch
3 and then release it.
To save energy, only switch the power tool on when using it.
 Check grinding tools before using. The grinding tool
must be mounted properly and be able to move freely.
Carry out a test run for at least one minute with no load.
Do not use damaged, out-of-centre or vibrating grind-
ing tools. Damaged grinding tools can burst and cause in-
juries.
Speed preselection (PWS 1000-125 CE/PWS 1300-125 CE)
The required speed can be preselected with the thumbwheel 4 (also while running).
The data in the following table are recommended values.
Material Application
Metal Removing paint
Wood, metal Brushing, rust removal

Metal Rough grinding
Masonry, stone Cutting

Working Advice

 Exercise caution when cutting slots in structural walls;
see Section "Information on Structures".
 Clamp the workpiece if it does not remain stationary
due to its own weight.
 Do not strain the machine so heavily that it comes to a
standstill.
Bosch Power Tools
Kickback stop (PWS 1000-125 CE/PWS 1300-125 CE)
Restarting Protection (PWS 1000-125 CE/
PWS 1300-125 CE)
The restarting protection feature prevents uncontrolled re-
starting of the machine after an interruption in the power sup-
ply.
To restart the operation, switch the On/Off switch 3 to the
Off position and start the machine again.
Reduced starting current (PWS 1000-125 CE/
PWS 1300-125 CE)
The electronic reduced starting current limits the power con-
sumption when switching the tool on and enables operation
from a 13 ampere fuse.
Note: When the machine runs with full speed after switching
on, the reduced starting current, the restarting protection
and the kickback stop features have failed. The power tool
must promptly be sent to an after-sales service agent for
maintenance; addresses, see Section „After-sales Service
and Application Service".
Constant Electronic Control (PWS 1000-125 CE/
PWS 1300-125 CE)
Constant electronic control holds the speed constant at no-
load and under load, and ensures uniform working perfor-
mance.
Accessory
Sanding disc
Cup brush, sanding disc
Grinding disc
Grinding disc
Cutting disc and cutting guide
(Cutting masonry/stone is permitted only with use
of the cutting guide)
 After heavily straining the power tool, continue to run
it at no-load for several minutes to cool down the acces-
sory.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
 Do not use the power tool with a cut-off stand.
Rough Grinding
 Never use a cutting disc for roughing.
English | 23
In case of a sudden drop in speed, e.g.,
caused by a jammed disc while cutting, the
power supply to the motor is electronically
interrupted.
To restart the operation, switch the
On/Off switch 3 to the Off position and start
the machine again.
