The arms' clamping force must be calculated in such a way that the saw can still be easily
be guided on the tube.
 Connect to the electrical power (230 V/50 Hz alternating current). Fuse protection: 16 A ti-
melag or appropriate circuit breaker.
The tube may contain unknown materials or objects. Make sure that the tube con-
tains no solids, gases or liquids!
3.4 Operation
Do not remove the protective cover! Before using, always check for correct operation!
Keep hands away from the saw blade and the sawing area! Keep hands on the control
handles! If both hands are gripping the saw, they cannot be caught in the saw blade!
 Turn the drive motor on with the switch (7) and set it to continuous operation.
 After pulling out the latching bolt (3), use the feed lever (4) to slowly move the saw blade
with the drive into the tube.
After a corresponding downward movement, the latching bolt engages on its own and locks
the saw in this position.
When guiding the saw, beware of the power cable! Replace damaged cables immedia-
tely!
 Now use the carrying handle (6) and guide handles (5) to guide the entire orbital circular
saw quickly but sensitively away from the operator (direction of arrow) and around the tube.
With correct handling and settings, after moving around the tube circumference, the orbital
circular saw will come to a stop at the same point where the sawing process began, and the
tube portion is completely separated. A cutting path of no more than 3 mm is normal.
If the saw blade binds, turn the drive motor off immediately!
 Turn the drive motor off at the switch (7).
Do not use lateral counter-pressure to brake the saw blade as it runs down!
 After the saw blade has stopped, unplug the electricity, pull the latching bolt (3) out, and use
the feed lever to lift the saw blade from the tube in rest position.
The latching bolt locks the saw, and by turning the hand wheel (1), it can be released and re-
moved from the tube.
When releasing the orbital circular saw, always hold it by the handle!
3.5 Changing saw blades
Always use perfectly sharpened saw blades that are suitable for the application. Saw
blades that are cracked or have changed shape are hazardous and must not be used!
Pull the electrical plug from the socket.

Open the safety flaps in the protective housing.

Press the lock button (1).

Twist off the fastening screw (2) in the centre of the saw

blade.
Replace the saw blade.

Attention! The equalization socket must be positioned! Attention! Observe the drive
motor's direction or rotation!
 Turn the fastening screw (2) tight again.
