1. If the power cable is damaged or cut
through while working, do not touch
the cable, and pull the power plug out
immediately. Never use the machine with
a damaged cable.
2. Wear protective glasses and hearing
protection. Dust is generated while
working that can be detrimental to
health, inflammable or explosive. Suitable
protective measure are required.
3. For example: Some types of dust are
considered to be carcinogenic. Use
suitable dust vacuuming and wear a dust
protection mask.
4. Light metal dust can burn or explode.
Always keep the workplace clean since
mixed materials are especially dangerous.
5. Wear protective gloves and sturdy shoes.
When necessary, also wear protective
clothing.
6. Connect machines that are used outdoors
by means of a fault current circuit breaker
(FI) with a maximum triggering current of
30 mA. Use only an extension cable that is

9. Take hold of the electric tool only by
the insulated handle when the cutting
tool could come in contact with hidden
wiring or its own power cable. Contact
with voltage carrying wiring can place the
metal parts of the machine also under
voltage and lead to an electrical shock.
10. Never stand on the machine. Serious
injury could occur if the tool is tipped or if
the cutting tool is accidentally started.
11. Use cutting discs whose allowable speed
is at least as high as the no load speed
of the machine. Check the cutting disc
before use.
12. Keep your body positioned to either side
of but not in line with the cutting disc. In
case of a burst disc, your body is better
protected from possible fragments.
13. The cutting disc must be flawlessly
mounted and be able to rotate freely.
Make a test run of at least one minute
without load. Do not use damaged, out of
round or vibrating cutting discs. Always
correctly adjust the depth stop. When

the cutting disc can cut into the surface
underneath the base plate.
14. During operation, the cutting disc cover
must be attached and the protective
pendulum hood must be functioning
properly.
15. Do not work with magnesium or materials
containing asbestos.
16. Protect the cutting disc from impacts,
shocks and grease.
17. Apply the machine to the work piece only
when it is switched on.
18. Keep your hands away from the rotating
cutting disc.
19. When cutting metal, sparks are
generated. Take care that no persons are
endangered. Because of the danger of
fire, no combustible materials should be
located in the vicinity (spark flying zone).
20. Blocking of the cutting disc leads to a
jerking reaction of the machine. In this
case, switch off the machine immediately.
21. Do not ram the cutting disc with force into
the work piece or apply too much pressure
when using the machine. Avoid especially
the catching of the cutting disc when
working on corners, sharp edges, etc.
When the cutting disc is damaged due to
misuse, it may develop cracks that could
lead to bursting without warning.
22. Avoid overloading the motor especially
when working with large work pieces.
When cutting, apply only light pressure to
the handle.
23. Observe the dimensions of the cutting
disc. The hole diameter must fit on the
tool spindle or the adapter without play.
24. Do not apply sideways pressure to the
cutting disc.
25. Observe the instructions of the
manufacturer for the mounting and usage
of the cutting disc.
26. Actuate the spindle locking only when the
cutting disc is at a standstill.

The machine should not be blocked by overload.
If the machine is operated with too much force, it will
not only reduce the power of the machine, but also
shorten the service life of the slices.
During cutting, the slices become very hot; they are not
touchable until they are cooled down.
Choose the appropriate slice according to the
workpiece.
Cutting depth
The cutting depth has been adjusted when the
machine leaves the factory. Generally speaking, if a
new 355 mm slice is used, it should not exceed the
lower plane of the base when cutting. If the chip has
been heavily worn, reduce the depth scale to balance
the gap.
When using new slices, it is necessary to adjust the
depth scale back to the original position at the time of
leaving the factory.
Correctly adjust the depth scale so that the
slice can not exceed the bottom plane of the
base when cutting the workpiece.
Adjust the cutting depth
Be sure to pull out the plug before doing any
repairs to the machine.
Use the attached wrench to loosen the cutting depth
adjusting bolt (14). Push the handle to adjust the arm
(16) to the desired position.
Turn the adjusting bolt (14) clockwise or
counterclockwise until the bolt head contacts the arm
housing.
Slowly raise the arm (16) and tighten the adjusting bolt
(14).
