1．Warning & Statements
Note：In order to reduce the hazards of fire, electrical shock
and injury, etc, the statements listed below shall be taken into
consideration upon application of electric tools.
1．Understand your electric tool fully by going through the user
manual carefully together with identifying the application,
limitation and potential risk accordingly.
2．Adopt protective appliances and act by conforming to the
due order strictly.
3．Remove all the regulatory instruments, and form the habit to
check about that prior to application of electric tools.

avoid slipping, and cut the hair to the proper length.
11．Remember to wear protective spectacles. Abundant dust may
come out in the buffing process, thus it’s necessary to wear
dust mask. Glasses in daily use incorporate lens with impact
resistance only, which could by no means meet the safety
requirements.

2．Voltage
Before connecting electric tool to the socket, make sure that
the supply voltage be in accordance with rated voltage. If the
former is greater than latter and the device is powered on by
mistake, it may result in damage of devices and injuries of people.
As for indefinite supply voltage of socket, never try to plug for
use. Besides, the damage of devices may also occur if the supply
voltage falls below rated voltage.
3. Device Application
As one of our products, the device belongs to the hand-held
electric tools.
The device mainly caters for lime surface, including the
interior wall, ceiling, exterior wall, corridor, etc. Remove the
painting lime mud from the wall, and make the surface even or
smooth. It may promote the wall grinding efficiency and quality
by workers.
With various conditions taken into consideration in the
design, the device may run at high or low speed to optimize the
grinding efficiency and realize user-friendly and compact design.

6. Installation & Sandpaper Replacement (See following
picture )
Note: Prior to installation or removing the sandpaper, make
sure to not only switch off the device, but also cut off the power
supply.
——Installation Guide
To ensure the replacement procedures, place the device on
the smooth ground prior to installation. Take the sandpaper from
the toolbox, and then fix it onto the disk (see Fig .2). The back of
the sandpaper (Item 1) will automatically glue with the
disk/adhesive disk (Item 2), making both connection and
conduction available.
In order to promote the grinding efficiency, it is necessary to
change the sandpaper after the device has been operational for a
certain period. Firstly, switch off the device and disconnect the

9
socket. Then, remove the previous sandpaper entirely from the
disk, so as to lay new sandpaper neatly as well as facilitate future
replacement. At last, fix new sandpaper in position.
——Sandpaper Overview
Grinding towards the target wall and object is possible with
abrasive grains and sandpaper twisting upon operations. The
sandpaper is classified into various categories according to its
dimensions. It is recommended to select the sandpaper in
accordance with actual size of the disk. The more abrasive grains
included on the sandpaper, the better flatness and parallelism can
be achieved via grinding, while the grinding efficiency will fall
accordingly and vice versa. Therefore, the sandpaper (Ф225mm)
is recommended upon actual needs.
:
Warning ：Prior to the sandpaper replacement or
installation, do read safety precautions and installation guide
carefully.
7．Installation & viscid disc Replacement (See following
picture)
If the viscid disc is damaged in the work, a new viscid disc can be
purchased from our company for replacement.
——Installation Guide

10
