Assembly
Mounting the Protective Devices

Before any work on the machine itself, pull the
mains plug.
Note: After breakage of the grinding disc during
operation or damage to the holding fixtures on the
protection guard/power tool, the machine must
promptly be sent to an after-sales service agent for
maintenance.
Protection Guard for Grinding
Release the clamping lever 7 . Place the protection
guard 5 with the encoding key 6 engaging into the
groove on the spindle collar until the shoulder of
the protection guard is seated against the flange of
the power tool, and turn the protection guard 5 to
the requested position. Lock the clamping lever 7 .
 Adjust the protection guard 5 in such a man-
ner that sparking is prevented in the direction
of the operator.
The tightening tension of the clamp from the pro-
tection guard 5 can be changed by loosening or
tightening the adjustment screw 8 . Ensure that the
protection guard 5 is tightly seated and check reg-
ularly.
Note: The encoding keys on the protection guard
5 ensure that only a protection guard that fits the
machine type can be mounted.
Protection Guard for Cutting
 For cutting with bonded abrasives, always use
the protection guard for cutting 9.
 Provide for sufficient dust extraction when
cutting stone.
The protection guard for cutting 9 is mounted in
the same manner as the protection guard for grind-
ing 5 .
Vibration-dampening Auxiliary Handle
 Operate your machine only with the auxiliary
handle 3.
Screw the auxiliary handle 3 on the right or left of
the machine head depending on the working meth-
od.
The vibration-dampening auxiliary handle reduces
the vibrations, making operation more comfortable
and secure.
 Do not make any alterations to the auxiliary
handle.
Do not continue to use an auxiliary handle if it is
damaged.
Hand Guard
 For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 14.
The hand guard 14 is fastened with the auxiliary
handle 3 .
Mounting the Grinding Tools
 Before any work on the machine itself, pull the
mains plug.
 Do not touch grinding and cutting discs before
they have cooled down. The discs can become
very hot while working.
Note for BAG 230-1 CLBB: It is recommended to
use the quick-clamping nut 13 . When using clamp-
ing nut 12 , an increased expenditure of force must
be taken into account when loosening the clamp-
ing nut.
Clean the grinder spindle
4 and all parts to be
mounted.
For clamping and loosening the grinding tools,
lock the grinder spindle with the spindle lock but-
ton 1 .
 Actuate the spindle lock button only when the
grinder spindle is at a standstill. Otherwise, the
machine may become damaged.
Quick-clamping Nut
With the quick-clamping nut 13 , grinding tools can
be mounted without additional tools.
 Use only a flawless, undamaged quick-clamp-
ing nut 13.
When screwing on, pay attention that the side of
the quick-clamping nut 13 with printing does not
face the grinding disc; the arrow must point to
the index mark 22.
Lock the grinder spindle
with the spindle lock but-
ton 1 . To tighten the
quick-clamping nut, firm-
ly turn the grinding disc
in clockwise direction.
A properly attached, un-
damaged quick-clamp-
ing nut can be loosened
by hand when turning
the knurled ring in anti-
clockwise direction.
Never loosen a tight
quick-clamping nut with
pliers. Always use the
two-pin spanner. Insert
the two-pin spanner as
shown in the illustration.
