Protection class
The values given are valid for a nominal voltage [U] of 230 V. For different voltages and models for specific countries, these values can vary.
Only for power tools without reduced starting current: Starting cycles generate brief voltage drops. Interference with other equipment/machines may
occur in case of unfavourable mains system conditions. Malfunctions are not to be expected for system impedances below 0.25 ohm.

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 ser-
vice agent for maintenance for addresses, see section "After-
sales Service and Application Service".
Protection Guard for Grinding
Place the protection guard 5 on the spindle collar. Adjust the
position of the protection guard 5 to the requirements of the
operation and lock the protection guard 5 with the locking
screw 6.
 Adjust the protection guard 5 in such a manner that
sparking is prevented in the direction of the operator.
Protection Guard for Cutting
 For cutting with bonded abrasives, always use the pro-
tection guard for cutting 13.

 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 13 is mounted in the same
manner as the protection guard for grinding 5.
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 24 is
mounted in the same manner as the protection guard for
grinding 5.
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 method.
Hand Guard
 For operations with the rubber sanding plate 20 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 18.
The hand guard 18 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.
Clean the grinder spindle 4 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 1.
 Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come damaged.
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 di-
rection-of-rotation arrow on the diamond cutting disc and the
direction of rotation of the machine (see direction-of-rotation
arrow on the machine head) agree.
See graphics page for the mounting sequence.
