2. Pressing angle
Do not press the whole surface of the grinding stone to
the grinding surface. It is recommended to use the disc
grinder by inclining it in 15-30 degrees as the picture to
do grinding work with circumference of the grinding
stone.
3. Grinding direction
When using a new grinding stone, be certain to grind
while pulling tool backwards (B direction) until the
grinding stone becomes rounded on its edge. Then, the
grinder can be moved to any direction.
This grinding stone (Grinding particle: A, Mesh: #36) is
best for heavy grinding in general steel materials. Also,
it can be used in wide range of other materials. For its
lower mesh, apply the grinding stone to the work
material lightly and grind steadily to create smooth
finishing surface that can be made by the grinding stone
with higher mesh.
4. Caution after use
Switch off to stop the rotation of the grinding stone, and
keep the disc grinder in safe place.
When you keep the disc grinder with the grinding stone
rotated in the place filled with dust and shavings, dust
and shavings can be gotten into the disc grinder.
The grinding stone can be cracked or
grooved by an impact. Please take care
not to impact on the disc grinder. If the
disc grinder is hit against something or
fallen down, you must check the
grinding stone and disc grinder.
5. How to rotate the head of the disc grinder
Remove the plug from plug socket before any operation.
For the above purpose, rotate the head of the disc
grinder in a 90-degree turn instead of rotating the
handle. And then, unscrew four screws and the head.
Do not remove the head from the main body wholly but
rotate to new position. After that, set four screws and
fasten them.

6. How to rotate the handle of the disc grinder
Disconnect the plug from the power
supply before making any maintenance.
1. Change of the grinding stone
Please change the grinding stone with new one when
outer diameter of the grinding stone in 180mm is worn
to
100mm
(For
the
grinding stone in 230mm is
130mm).
2. Screws
Make sure screws in each part are set tightly at regular
intervals. When screws are loose, fasten them tightly.
The loose screw causes the danger situation.
3. Carbon brush
Disposable carbon brush is used in the motor. The
heavily worn carbon brush causes the trouble of the
motor.
When the length of the carbon brush is reached at the
wear tolerance line, change it with new carbon brush.
Also, keep the carbon brush clean to be moved in the
brush holder freely.
