Long-term switching on / off

Switching on:

In order to switch on the power tool move locking

button 8 forward and while holding it in this position,

push on / off switch 7 (see fig. 9.1). On / off switch 7

is will be lock in "On" position and no need to hold it

while working�

Switching off:

Push and release on / off switch 7 (see fig. 9.2).

Design features of the power tool

Vibration-dampening additional handle

Vibration-dampening additional handle 6 reduces the

negative influence of vibration on body work, making

work safer and more comfortable�

Speed selector thumbwheel

Using speed selector thumbwheel 3, you may select

the required spindle speed (also during operation)�

The required speed is dependent on the material and

can be determined with practical trials�

When operating your power tool at a low speed for a

long time, it has to be cooled down for 3 minutes� To

do it, set a maximum speed and leave your power tool

to run idle�

Soft start

Soft start (limiting system of starting current) enables

smooth start of power tools - the disc is being run up

gradually with no jerks and kickbacks; no jump-like

load is imposed on the motor upon switching�

Recommendations on the power tool op-

eration

• You can hold the power tool in two ways:

• hold by the rear handle and for the vibration-

dampening additional handle 6 (see fig. 10);

• hold by the rear handle and housing of reducer 4

(see fig. 11.1). While holding the power tool with

this method, hold the housing of reducer 4 firmly

and pinch your fingers as shown in figure 11.1.

Attention: it is strictly forbidden to hold the

housing of reducer 4 using the method shown in

figure 11.2, this can cause serious injuries.

• It is strongly recommended to use liquid polishing

compounds� Never use abrasive or grinding com-

pounds� Abrasive components may damage coated

surfaces�

• Run the power tool idle for one minute before the

operation�

The manufacturer reserves the possibility to introduce changes.

• Regularly apply the polishing compound on the sur-

face during polishing�

• When applying the polishing compound on the pol-

ishing accessory leave approximately one forth of the

working surface uncovered by the compound�

• The quality of polishing depends on proper selection

of the rotation speed, which is mainly determined by

the material being processed�

• High speed is set when high quality of polishing is

not required�

• Use low speed to deliver the best quality of polishing

and to achieve high finish of the surface.

• If the part being processed is heated up, stop opera-

tion and let it cool down to avoid deformation�

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� Regularly

flush the power tool with compressed air thought the

ventilation slots 2�
