Assembly
Avoid unintentional starting of the ma-
chine. During assembly and for all work on
the machine, the power plug must not be
connected to the mains supply.
Note: To ensure safe handling, the rests of the
base plate 9 must be placed on a suitable sup-
porting surface (e. g., workbench, level floor,
etc.).
Changing the Tool
(see figure A)
Before any work on the power tool itself,
pull the mains plug.
Use only cutting discs that have an equal or
higher maximal allowable speed than the no-
load speed of your power tool.
Use only cutting discs that correspond to the
characteristic data given in these operating in-
structions and are checked according to
EN 12413 and marked appropriately.
Removing the Cutting Disc
– Place the machine in the working position.
(see "Releasing the Machine (Working Posi-
tion)", page 10)
– For machines with retracting blade guard:
Tilt the retracting blade guard 10 upward to
the stop.
For machines without retracting blade
guard: Unscrew the cover lid 23.
– Turn the hexagon socket screw 21 with the
box-end wrench 8 (size 15 mm) provided and
at the same time press the spindle lock 11
until it engages.

Installing the Cutting Disc
If required, clean all parts to be mounted before
installing.

spindle 18 in such a manner that its lable
faces away from the tool arm.

and the hexagon socket screw 21. Press the
spindle lock 11 until it engages and tighten
the hexagon socket screw. (Tightening
torque approx. 18–20 Nm)

guard: Screw the cover lid 23 on again.
Operation
Transport Safety-lock
Before any work on the power tool itself,
pull the mains plug.
The transport safety-lock 6 enables easier han-
dling of the power tool when transporting to var-
ious working locations.
Releasing the Machine (Working Position)
– Push the tool arm downward somewhat by
the handle 1 to releave the load on the trans-
port safety-lock 6.
– Pull the transport safety-lock 6 completely
outward.
– Guide the tool arm slowly upward.
Note: When working, pay attention that the
transport safety-lock is not pushed inwards.
Otherwise, the tool arm cannot be lowered to
the requested depth.
Securing the Machine (Transport Position)
– Lower the tool arm until the transport safety-
lock 6 can be pushed completely inward.
