APPLICATIONS
䡬
Removal of casting fin and finishing of various types
of steel, bronze and aluminum materials and castings.
䡬 Grinding of welded sections or sections cut by
means of a cutting torch.
䡬 Grinding of synthetic resins, slate, brick, marble, etc.
䡬 Cutting of synthetic concrete, stone, brick, marble
and similar materials.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified 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 sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Fitting and adjusting the wheel guard (Fig. 1)
The wheel guard is a protective device to prevent
injury should the depressed center wheel shatter
during operation. Ensure that the guard is properly
fitted 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 effectiveness. Ensure that
the setting screw is thoroughly tightened after
adjusting the wheel guard.
5. Ensure that the depressed center wheel to be utilized
is the correct type and free of cracks or surface
defects. Also ensure that the depressed center wheel
is properly mounted and the wheel nut is securely
tightened. Refer to the section on “ASSEMBLING
AND DISASSEMBLING THE DEPRESSED CENTER
WHEEL”.
6. Conducting a trial run
Ensure that the abrasive products is correctly
mounted and tightened before use and run the tool
at no-load for 30 seconds in a safe position, stop
immediately if there is considerable vibration or if
other defects are detected.
If this condition occurs, check the machine to
determine the cause.
7. Confirm the spindle lock mechanism
Confirm that the spindle lock is disengaged by
pushing push button two or three times before
switching the power tool on (See Fig. 1).
8. Fixing the side handle
Screw the side handle into the gear cover.
PRACTICAL GRINDER APPLICATION
1. Pressure
To prolong the life of the machine and ensure a
first class finish, 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 sufficient for effective grinding.
Too much pressure will result in reduced rotational
speed, inferior surface finish, and overloading which
could reduce the life of the machine.

– Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become
necessary to clear dust, first disconnect the tool
from the mains supply (use non metallic objects)
and avoid damaging internal parts;
– Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves,
helmet and apron should be worn;
– Pay attention to the wheel that continues to rotate
after the tool is switched off.
