Eccentricity and rotational movement mode (rough grinding and polishing)
Eccentricity and rotational movement mode is a combination of rotation movement and eccentricity movement. The
selection of this mode can realize rapid rough grinding and polishing.
Put the rotary switch (1.1) at the place with the dot direction arrow.
Eccentric motion (finely grinding)
Gear grinding speed is slow, but can effectively remove scratches.
The rotary switch (1.1) placed it clearly pointing to the position of arrows.
Selection and installation of the grinding pad
According to the difference of material surface's quality that needs to be treated, there are three grinding pads with different
hardness to choose
Hard: Surface in coarsely grinding and edge in grinding
Soft: used for plat surface and curved surface in coarsely grinding and fine grinding
Super soft: used for the finely grinding and forming parts, curved surface, and corners, can not be used for edge in grinding.
Quick installation system of the grinding pad:
-With the help of screwdriver to unscrew 4 screws, (2.2) take the grinding pad off
-Place the new grinding pad aligning with corresponding holes with the help of screwdriver to tighten 4 screws (2.2.).
Installation of the Grinding Materials
Sandpaper and wool pad can be conveniently and quickly installed on the substrate of the grinding pad. Through the design
application of nylon buckle, sandpaper can conveniently pull in the grinding pad.
And sandpaper can be conveniently taken off after use.
Dust Absorption
The grinder shall be regularly connected to the vacuum cleaner.
Connect the vacuum cleaner suction pipe to vacuum interface which is located on the back of grinder (1.5).
If necessary, remove dust collecting bin (3.1). Unscrew the locking screw (3.2), with your two hands holding the dust
collecting bin; slowly pull back and then it can be removed.

Auxiliary Handle
Auxiliary handle (Annex 4.1) can be installed on the left or right side of the gear box according to users' habit.

Starting Operation

In the process of grinding, ensure the work pieces are fixed solidly. In order to ensure the safety in the process of operation,
hold the motor (1.3), and the end of the gear box (1.6) or auxiliary handle (Annex 4.1) with your hands.
During grinding, do not artificially apply excessive pressure to the grinder. If the pressure is moderate, it has achieved the best
results of grinding. Sanding effect mainly depends on the correct choice of the grinding materials.
Table A and B display the recommended settings when grinding or polishing in different materials.
Metals in Grinding
For security reasons, pay attention to the following preventive measures on the process of metal grinding:
Install a residual current circuit breaker in advance.
•
Make sure the grinder is connected with a suitable precipitator.
