Bosch 0 601 7D1 600 Original Instructions Manual page 33

Hand guard
Always fit the hand guard (26) when working with the
u
rubber sanding pad (27) or with the cup brush/conical
brush/diamond annular cutter.
Attach the hand guard (26) to the auxiliary handle (8)/(9).
Standard auxiliary handle/low-vibration auxiliary handle
Screw the auxiliary handle (8)/(9) on the right or left of the
machine head depending on the working method.
Do not operate your power tool without the auxiliary
u
handle (8)/(9).
Do not continue to use the power tool if the auxiliary
u
handle (8)/(9) is damaged. Do not make any altera-
tions to the auxiliary handle (8)/(9).
The low-vibration auxiliary handle (9)
reduces vibration, enabling the tool to
be used safely and more comfortably.
Fitting the Abrasive Tools
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Clean the grinding spindle (25) and all the parts to be fitted.
Lock the grinding spindle with the spindle lock button (2)
before clamping and releasing the abrasive tools.
Do not press the spindle lock button while the grind-
u
ing spindle is moving. The power tool may become dam-
aged if you do this.
Grinding/cutting disc
Pay attention to the dimensions of the abrasive tools. The
diameter of the hole must match that of the mounting flange.
Do not use an adapter or reducer.
When using diamond cutting discs, make sure that the direc-
tion of rotation arrow on the diamond cutting disc corres-
ponds to the direction of rotation of the machine (see direc-
tion of rotation arrow on the housing).
See the graphics page for fitting instructions.
Note: When assembling bonded grinding or cutting discs us-
ing the supplied mounting flange (14) and the clamping
nut (21) or quick-clamping nut (22), the use of intermediate
layers is not necessary.
To secure the grinding/cutting disc, place the mounting
flange with O-ring (14) on the grinding spindle (25) and
screw on the clamping nut (21). Ensure the alignment of the
clamping nut (21) depending on the grinding/cutting disc
used (see figures in the front part of the operating manual),
and tighten them with the two-pin spanner (see " Quick-
clamping nut ", page 33).
Note for GWS 17-125 SB and GWS 17-125 PSB: Assembly
of the mounting flange (14) does not apply, as this is already
securely preassembled.
To remove the sanding or cutting disc, an increased loosen-
ing torque is required for the clamping nut (21).
When using the quick-clamping nut (22) (see " Quick-clamp-
Bosch Power Tools
ing nut ", page 33), no increased loosening
torque is required.
After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
A plastic part (O-ring) is fitted around
the centring collar in the mounting
flange (14). If the O-ring is missing
or damaged, the mounting flange
(14) must be replaced before opera-
tion can resume.
Note for GWS 17-125 SB and GWS 17-125 PSB: An O-ring
is fitted. If this O-ring is missing or damaged or the mounting
flange can be released completely from the spindle, the
mounting flange must be replaced by a customer service
centre authorised by Bosch.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (22) in-
stead of the clamping nut (21).
The quick-clamping nut (22) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (22) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (22) is not facing the grinding disc;
the arrow must be pointing towards the index mark (35).
Press the spindle lock button (2) to
(35)
lock the grinding spindle. To tighten
the quick-clamping nut, turn the grind-
ing disc firmly clockwise.
If the quick-clamping nut has been at-
tached correctly and is not damaged,
you can loosen it by hand by turning
the knurled ring anticlockwise. If the
quick-clamping nut is stuck, do not
attempt to loosen it with pliers – al-
ways use the two-pin spanner. Posi-
tion the two‑pin spanner as shown in
the figure.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
