angle of the cutting disc to the workpiece while cutting. Cut only in a straight line. Failure to follow the above recommendations
increases the risk of jamming the cutting disc in the workpiece, which can cause the tool to bounce towards the operator, break
the disc or fall apart.
When cutting, guide the grinder towards the rotation of the disc (VIII).
When working with the grinder, do not exert too much pressure on the workpiece and do not make sudden movements in order
not to cause jamming or cracking and tearing of the abrasive disc.
Do not overload the tool, the temperature of the external surface must never exceed 60°C.
After fi nishing work, turn off the grinder, remove the battery and inspect it.
Caution! The disc may be still spinning for some time after turning the grinder off . Wait for the disc to cool down before starting the
inspection. During operation, both the disc and the material to be processed can become heated to high temperatures.
Remember! When operating with an angle grinder:
Always use an eye guard.
Do not use abrasive discs with a maximum permissible circumferential speed of less than 80 m/s.
Do not use abrasive discs with a maximum permissible rotational speed of less than the grinder's rotational speed.
ASSEMBLY OF THE ACCESSORIES OF THE STRAIGHT GRINDER
CAUTION! All operations mentioned in this chapter must be carried out with the power supply disconnected – the battery must
be disconnected from the tool!
Installation of tooling in the tool chuck (II)
It may be necessary to loosen the fi xing nut before inserting a tool into the chuck. To do this, hold the spindle with one spanner
and unscrew the nut with the other. The nut should not be completely taken off the chuck.
Place the shank of the tool in the chuck. There must be a gap of no more than 8 mm between the working part of the tool and the
chuck. Moreover, make sure that at least half of the tool shank is inside the chuck.
Remove the tooling by by loosening the fi xing nut.
Warning! The tooling might be hot immediately after fi nishing work. Allow it to cool down itself before removing.
STRAIGHT GRINDER OPERATION
Starting and stopping the grinder
Before starting the grinder, hold it with both hands on the handles or isolated housing elements and make sure that the tool does
not come into contact with any objects. The direction of rotation of the spindle is indicated by an arrow on the tool housing near
the tool chuck.
Start the tool by pressing and holding the back of the on/off button and then sliding it forward (III). The on/off switch can be locked
in the front position which can be helpful during prolonged work.
When the tool is started up, hold it in this position for about 30 seconds, watching for any suspicious noises, excessive noise or
excessive vibration.
If no signs of malfunction are found, the tool should be switched off by releasing pressure on the switch or, if it was locked, by
pressing the back of the switch button. The button retracts automatically, but the tool can still move for some time after the switch
is released.
The tool can be put away only after the inserted tool has come to a complete standstill.
Speed control (IV)
Speed control is only possible when the supply battery is connected.
Press the button and the lights next to the gear number are illuminated one after another. The higher the number of gears, the
higher the speed. Once the highest speed is reached, the next press of the button will shift to the lowest speed gear. Lower gears
have lights illuminated in green and higher gears have lights illuminated in red.
USING THE STRAIGHT GRINDER
Basic precautions must be taken when using grinding stones. Before each use, the grinding stones should be visually inspected
for damage and deformation. It is forbidden to use grinding stones in which any damage has been found. Grinding stones should
not be thrown, struck or violently applied to the workpiece. This can cause the grinding stone to disintegrate, resulting in serious
injury.
The shank of the tooling must not protrude more than 8 mm from the chuck.
Use accessories according to their intended use. For example, do not grind with discs designed for cutting, do not use drill bits
for side milling.
Before fi tting the tooling, set the correct operating speed for the type of equipment. After installation, allow the too to reach its full
