Fitting Protective Equipment
u
Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage.
There is risk of injury
from unintentionally pressing the on/off switch.
Note: If the grinding disc breaks during operation or the
holding fixtures on the protective guard/power tool become
damaged, the power tool must be sent to the after-sales ser-
vice immediately; see the "After-Sales Service and Applica-
tion Service" section for addresses.
Protective guard for grinding
Place the protective guard
(8) onto the holder on the
power tool until the coding
cams of the protective
guard are aligned with the
holder. When doing so,
press and hold the unlock-
ing lever
(1) .
Press the protective guard
(8) onto the spindle collar
until the shoulder of the
protective guard is sitting
on the flange of the power
tool and rotate the protect-
ive guard until it audibly
clicks into place.
Adjust the position of the protective guard
(8) to meet the
requirements of the operation. To do this, push the unlock-
ing lever
(1) upward and rotate the protective guard (8) into
the required position.
u
Always position the protective guard (8) such that all
three cams on the unlocking lever (1) engage in the
corresponding openings on the protective guard (8).
u
Adjust the protective guard (8) such that sparking in
the direction of the operator is prevented.
u
The protective guard (8) must only be adjustable
while the unlocking lever (1) is actuated. Otherwise,
the power tool must not be used any more under any
circumstances and must be sent to the after-sales ser-
vice.
Note: The coding cams on the protective guard (8) ensure
that only a protective guard that is suitable for the power
tool can be fitted.
Protective guard for cutting
u
Always use the protective guard for cutting (12) when
cutting bonded abrasives.
u
Provide sufficient dust extraction when cutting stone.
The protective guard for cutting (12) is fitted in the same
way as the protective guard for grinding (8) .
Extraction guard for cutting with a guide block
The extraction guard for cutting with a guide block (22) is fit-
ted in the same way as the protective guard for grinding (8) .
Side handle
u
Do not operate your power tool without the side
handle
(7) .
Screw the side handle (7) on the left or right of the machine
head depending on how your are working.
Low-vibration auxiliary handle
The low-vibration auxiliary
handle reduces vibration,
enabling the tool to be used
safely and more comfort-
ably.
u
Do not make any alterations of any kind to the auxili-
ary handle.
Do not continue to use a damaged auxiliary handle.
Hand guard
u
Always fit the hand guard (16) when working with the
rubber sanding plate (17) or with the cup brush/disc
brush/flap disc.
Attach the hand guard (16) to the side handle (7) .
Fitting the abrasive tools
u
Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage.
There is risk of injury
from unintentionally pressing the on/off switch.
u
Do not touch grinding and cutting discs until they have
cooled down.
The discs can become very hot while work-
ing.
Clean the grinding spindle (15) and all the parts to be fitted.
Lock the grinding spindle with the spindle lock button (3)
before clamping and releasing the abrasive tools.
u
Do not press the spindle lock button while the grind-
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 grinding tools. The
mounting hole diameter must fit the mounting flange without
play. Do not use reducers or adapters.
When using diamond cutting discs, pay attention that the
direction-of-rotation arrow on the diamond cutting disc and
the direction of rotation of the machine (see direction-of-ro-
tation arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the clamping
nut
(11) and tighten with the two-hole spanner.
