Additional handle SOFTGRIP

The additional handle (17) can be screwed from the left or right gear-

box (5) side or from the top gearbox (5) part. Thanks to the special de-

sign vibrations are reduced by the additional handle (17).

Grinding or cutting wheel fixing

Attention! Prior to handling the accessories, the power 

supply cable has always to be disconnected from the power 

source socket!

Mounting with the standard clamping nut

Clean the bottom flange (11) and the clamping nut (13) as well as the 

clamping surfaces of the grinding or cutting wheel. Place the bottom 

flange (11) (by the recess out) on the spindle (7). Place the grinding or 

cutting wheel (12). The bottom flange recess (11) must be inserted pre-

cisely into the grinding wheel or the cutting wheel hole. Then put the 

clamping nut (13) on the spindle (7) so that when fixing the grinding 

wheel, the clamping nut recess (15) must be faced towards the wheel 

and when fixing the cutting wheel, the clamping nut recess (15) must 

be directed from the wheel!
Depress the lock spindle pin (3).

Attention! Use the lock spindle pin (3) only if the spindle is 

at rest and the grinder is de‑energized.

Swivel the wheel /spindle, until the lock spindle pin (3) is engaged. 

Tighten the clamping nut (13) firmly, using the wrench (16).

Attention! Prior to starting the grinder, verify that the 

wheel does not rotate freely between the bottom 

flange (11) and the clamping nut (13).

Mounting with quick‑clamping nut

The quick-clamping nut must be tightened or loosened by hand only 

(never use any additional tool!). Mounting of the grinding or cutting 

wheel is the same like for the grinder without the quick-clamping nut, 

with the sole difference, that after spindle locking the quick-clamping 

nut (14) may be tightened by hand only.

Attention! Do not tighten the quick‑clamping nut without 

the wheel not to damage its mechanism!

Attention! Prior to starting the grinder, verify that the 

wheel does not rotate freely between the bottom 

flange (11) and the clamping nut (14).

Putting into operation

Check whether the data on the rating plate match with the real power 

supply voltage. The tool intended for 230 V~ may be also connected to 

220/240 V~. Check whether the plug type corresponds to the socket 

type.

Switching on

Push the switch (1) forwards, thus switching the machine on. If you de-

press the front switch button part (1), the switch will be arrested in the 

ON position.

Switching off

By releasing the switch button (1), the switch will be returned to the 

initial position and the machine will be switched off. If the switch (1) 

is arrested in the ON position, then by moderate depressing the rear 

switch button part (1), the switch will be released and returned to the 

initial position, i.e. the machine will be switched off.

Motor electronics

Starting current limitation

Electronically controlled continual running secures device acceleration 

without back thrust. Due to starting current limitation in the device, 

16 A protection is suffi cient.

Switching off during back thrust

During sudden drop of revolutions, for example blocking in dividing cut, 

the current input in motor stops. For re-starting, the device must be first 

switched off and again switched on.

Protection against re‑starting

Prevent uncontrolled starting of the device after current supply cut off. 

For re-starting, the device must be fi rst switched off and again switched 

on.

Grinding and cutting discs

Check that the label on the disc shows the permissible peripheral speed 

or permissible revolution speed.
If the permissible revolution speed is given on the disc, it must not be 

lower than the highest no-load speed of the grinder.
Discs with a permissible peripheral speed of 80 m/s and higher may be 

used.
Test new cutting discs by letting them run for about one minute with 

no load.
Unbalanced or vibrating discs should not be used and should be dis-

carded.
Protect grinding discs from shock, impact and lubricants.
If the grinding and cutting wheels are worn down to the mark on the 

wheel guard (see the arrow sign), they should be replaced with new 

ones. This maintains the optimum grinding and cutting performance 

of the machine (peripheral speed of the grinding and cutting wheels).

Maintenance and service

Attention! Risk of el. shock. Prior to start any operation, 

pull the plug out of the socket!

Vent holes (2) of the motor guard may not be covered.
Cable replacement must be carried out by a specialized service station 

authorized correspondingly.

After ca 200 hours of operation the following activities and works 

have to be carried out:

Check of brush length. The brushes shorter than 5 mm have to be re-

placed for new ones.
The grinder will be stopped automatically if the brushes are worn. The 

grinder is sent to the service station for maintenance.
Grease replacement in gearbox and bearings.

Attention! With respect to protection from el. shock and 

preservation of the class of protection, all maintenance 

and service operations requesting jig saw case removal 

must be performed by the authorized service centre only!

Storage

Packed appliance may be stored in dry, unheated storage place with 

temperature not lower than -5 °C.
Unpacked appliance should be stored only in dry storage place with 

temperature not lower than +5 °C with exclusion of all sudden temper-

ature changes.

Environmental protection

Power tools, accessories and packaging should be sorted for environ-

mental-friendly recy.

Only for EU countries:

Do not dispose of power tools into household waste!
According to the European Directive 2002/96/EC on waste electrical and 

electronic equipment and its incorporation into national law, power 

tools that are no longer suitable for must be separately collected and 

sent for recovery in an environmental-friendly manner.
