Protective casing
Always use protective casing 1 when ap-
plying cutting and grinding discs. Opera-
tion of the aforementioned accessories
without protective casing 1 is strictly
forbidden. Protective casing 1 should always face
the operator with its closed part.
Mounting / dismounting the protective casing (see
fig. 2)
• With a screwdriver (not supplied with the power tool)
release screw 11 and install protective casing 1 onto
the spindle neck, watching that mounting lug 10 comes
into the longitudinal groove of the spindle neck (see
fig. 2).
• Turn protective casing 1 into the required position
and tighten screw 11 with a screwdriver (not supplied
with the power tool)�
• When dismounting protective casing 1 repeat the
aforementioned operations in reverse order�
Mounting / replacement of accessories
After mounting accessories of any kind,
make a trial run before commencing op-
eration - start the power tool and let it
work in idle mode for not less than 30
seconds. The operation of accessories with radial
or axial run-out and causing increased vibration of
the power tool is strictly forbidden.
Wearing protective gloves is recom-
mended for mounting / replacing acces-
sories.
Mounting of cutting / grinding disc (see fig. 3)
• Install flange 13 onto spindle 12 (see fig. 3).
• Install one of the aforementioned accessories onto
spindle 12�
• Press and hold spindle lock 3�
• Screw clamping nut 15 onto spindle 12 and tig h ten it
with flange wrench 9� Attention: at mounting any ac-
cessories over 4 mm thick clamping nut 15 should
be turned over (see fig. 3).
• Release spindle lock 3�
Replacing the cutting / grinding disc (see fig. 3-4)
• Press and hold spindle lock 3�
• Release clamping nut 15 with flange wrench 9 (see
fig. 4).
• Replace the accessory�
• Screw clamping nut 15 onto spindle 12 and tighten it
with flange wrench 9� Attention: at mounting any ac-
cessories over 4 mm thick clamping nut 15 should
be turned over (see fig. 3).

on the power tool operation
Cutting (see fig. 5.1)
• Install cutting disc as described below�
• Start the power tool, wait until the engine gains its
maximum speed and only after that, smoothly bring
cutting disc to the surface processed�
• Do not apply excessive pressure to the power tool,
as it will not bring better results but it will overload the
engine and wear out cutting disc faster�
• Move the power tool along the cutting line with mod-
erate feed, not distorting and not making vibrating and
bursting movements�
• Cutting should be implemented in the direction
shown on fig. 5.1. When cutting in the reverse direc-
tion the danger of uncontrolled throwing of the power
tool out to the side of the operator, which can lead to
serious injuries appears�
Grinding (see fig. 5.2)
Grinding is applied for the rough and quick grinding of
metals, the processing of welding seams, etc� Select
the type of grinding disc depending on the work, which
you are going to implement�
• Install grinding disc as described above�
• Start the power tool, wait until the engine gains its
maximum speed and only after that smoothly bring
grinding disc to the surface processed�
• Holding the power tool at an angle of 10° to 15° relating
to the surface processed (see fig. 5.2) is recommended.
If this angle is less than recommended, it will make con-
trolling the power tool more difficult. If this angle is more
than recommended, the processing quality will decrease
and grooves will be left on the billet surface�
• Make alternate-reciprocal movements applying
moderate pressure to the power tool� Excessive pres-
sure will not bring better results but it will overload the
engine and create the danger of destruction of grinding
disc, which can cause severe injuries�
Power tool maintenance /
preventive measures
Before carrying out any works on the power tool it
must be disconnected from the mains�
Cleaning of the power tool
An indispensable condition for a safe long-term exploi-
tation of the power tool is to keep it clean� During the
