Removing the grinding wheels
Turn off the grinder and remove the battery.
Press the spindle lock and loosen the lower mounting fl ange with the wrench for mounting, and then remove the abrasive wheel
from the spindle. Clean the spindle and clamping fl anges of dust and other pollutants arising in the course of work.
Types of abrasive wheels
You can use for grinder all grinding wheels designed for use with angle grinders with a permissible peripheral speed of at least 80
m/s and fi xing and external diameters specifi ed in the technical data table.
If the grinding wheel is equipped with an unthreaded hole, for its mounting you should use the mounting fl anges.
It is also possible to mount the grinding wheels with an outside diameter specifi ed in the technical data table, equipped with a
threaded hole M14. In this case, you should not use the mounting fl anges, and the grinding wheel should be screwed directly
to the spindle, by blocking it with a button, and by tightening the blade fi rmly and securely with a fl at wrench (the grinder is not
equipped with it).
In the case of wheels, which allow for mounting the sandpaper wheel by using Velcro, you should only use the sandpaper wheels,
which are specifi ed in the table of technical data. The wheels should be placed concentrically on the grinding wheel. The edge of
the wheel should not protrude beyond the wheel edge.
It is also possible to use diamond grinding wheels with dimensions specifi ed in the technical data table, intended for cutting and
dry grinding. Installation should be carried out in the same way as for grinding wheels.
For metal treatment it is recommended to use grinding wheels made of materials intended for the processing of a given type of
metal. Refer to the documentation that is attached to the grinding wheel.
For the processing of ceramic materials you can use the grinding wheel or diamond grinding wheels, designed for a dry work.
Wire brushes and sanding wheels are recommend for removing old paint coatings from metal parts.
It is prohibited to modify the mounting hole, spindle or use reduction rings in order to align the mounting hole diameter to the
diameter of spindle. It is prohibited to use grinding wheels with a mounting diameter other than the diameter specifi ed in the tech-
nical data table. It is forbidden to use wheels with the cutting chain or disk saws. because that increases the risk of tool rebound
toward the operator.
Attention! It is forbidden to use other grinding wheels than those, which are approved for use in this manual. Even if they can be
mounted on the grinder spindle. Inappropriate grinding wheels may not withstand the loads generated during the operation of the
angle grinder. Damaged, crumbling grinding wheels create a threat of serious injury or death.
USE OF THE GRINDER
Remove the battery from the power tool socket!
Before working with the tool, you should check whether the enclosure, cover and battery are not damaged.
If there are any visible damages it is prohibited to operate the grinder!
Attach the cover of grinding wheel and the handle.
Never work with the grinder without correctly mounted grinding wheel guard!
Choose the type of grinding wheel, which is appropriate for the type of work, and mount the grinding wheel on the grinder
spindle.
Workpiece should be mounted in an appropriate way, so it does not move during its machining, for example, by clamps or clips.
The wheel of grinder spins at high speed and improper mounting of the workpiece can cause its uncontrolled movement during
operation, which increases the risk of injury.
In the case of cutting you should support the cut material on both sides of the cut line, but in such a way, that during cutting it would
not cause the grinding wheel jam. Supports should be positioned near the edges of cut material, and near the cut line.
Wear eye protection, hearing protectors and working gloves.
Check, whether the switch is in the "off - 0" position. Then connect the battery to the power tool.
Adopt the proper body position, which is needed to maintain balance, and run the grinder by its switch.
The switch has a security lock to prevent accidental starting of the grinder. Move the lock back so it will be at level of the switch
surface, and then will allow to press it. The switch does not have the possibility of blocking in the ON position, you should hold it
all the time during the work.
Proceed to work by applying the proper surface of the grinding wheel to workpiece:
- in the case of grinding wheels for grinding you should grind by the side and/or front surface,
- in the case of fl ap grinding wheels you should grind by the surface side so that the sandpaper leaves would move parallel to
the workpiece,
- in the case of wheels with Velcro, which allow for fi xing the abrasive paper, grinding must be carried out by side surface,
- in the case of wire brushes the treatment should be done by wires endings, not by their side surface,
- in the case of grinding wheels for cutting, you should cut by their front surface, do not grind by the front surface of grinding
wheels, which are designed for cutting.
When grinding with a side surface you should keep the grinder at an angle of no more than 30 degrees with respect to the treated
surface (VII). Move the grinder forward and back by smooth moves.
