6. To prolong the life of the machine and ensure a
fi
rst
class
fi
nish, it is important that the machine should not
be overloaded by applying too much pressure. In most
applications, the weight of the machine alone is su
ffi
cient
for e
ff
ective grinding. Too much pressure will result in
reduced rotational speed, inferior surface
fi
nish, and
overloading which could reduce the life of the machine.
7. The wheel continues to rotate after the tool is switched
o
ff
.
After switching o
ff
the machine, do not put it down until the
depressed center wheel has come to a complete stop.
Apart from avoiding serious accidents, this precaution
will reduce the amount of dust and swarf sucked into the
machine.
8. When the machine is not use, the power source should
be disconnected.
9. Be sure to switch OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident
before the depressed center wheel is assembling and
disassembling.
10. RCD
The use of a residual current device with a rated residual
current of 30 mA or less at all times is recommended.

APPLICATIONS
○
Removal of casting
fi
n and
fi
nishing of various types of
steel, bronze and aluminum materials and castings.
○
Grinding of welded sections or sections cut by means of
a cutting torch.
○
Grinding of brick, marble, etc.
○
Cutting and scribing of concrete, stone, tile, (use the
diamond wheel)
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms to the
power requirements speci
fi
ed on the product nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If the
plug is connected to a receptacle while the power switch
is in the ON position, the power tool will start operating
immediately, which could cause a serious accident.
3. Extension cord
When the work area is removed from the power source,
use an extension cord of su
ffi
cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Con
fi
rming condition of the environment
Con
fi
rm that the work site is placed under appropriate
conditions conforming to prescribed precautions.
When grinding a thin steel plate, depending upon the
state of the workbench, a loud noise will be created due
to resounding noise from the steel plate being ground. To
eliminate unwanted noise in this instance, place a rubber
mat beneath the material to be ground.
5. Mounting the wheel guard
The wheel guard is a protective device to prevent injury
should the depressed center wheel be shattered during
operation. Ensure that the wheel guard is properly
fi
tted
and fastened before commencing grinding operation.
By slightly loosening the setting screw, the wheel guard
can be turned and set at any desired angle for maximum
operational e
ff
ectiveness. Ensure that the setting screw
is thoroughtly tightended after adjusting the wheel guard.
6. Con
fi
rming and mounting the depressed center
wheel.
Thoroughly check that a speci
fi
ed depressed center
wheel is free of cracks and splits is mounted.
Con
fi
rm that the depressed center wheel is mounted
under the speci
fi
ed condition and is
fi
rmly clamped.
For details, refer to the item “Assembling and
Disassembling the depressed center wheel.”
7. Apply a trial run
To start grinding work without checking for possible
cracks and splits in the depressed center wheel is very
dangerous. Prior to start of grinding, direct the grinder
in a direction where no one is present, and apply a trial
run without fail to con
fi
rm that the grinder displays no
abnormalities.
Duration of the trial run is as follows:
When depressed center wheels is replaced
............................................... 3 minutes or more
When starting daily work ................1 minute or more
8. Con
fi
rm the spindle lock mochanism.
Con
fi
rm that the spindle lock is disengaged by pushing
the push button two or three times before switching the
power tool on (See
Fig. 2
)
9. Fixing the side handle.
Screw the side handle into the gear cover.
