PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specifi 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 suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Fitting and adjusting the wheel guard
The wheel guard is a protective device to prevent injury
should the depressed center wheel shatter during
operation. Ensure that the guard is properly fi tted and
fastened before commencing grinding operation.
5. Inspect the depressed center wheel before use, do not
use chipped, cracked or otherwise defective products.
6. Always hold the body handle and side handle of the
power tool fi rmly. Otherwise the counterforce produced
may result in inaccurate and even dangerous operation.
7. Do not use cutting-off wheels for side grinding.
8. Do not use of separate reducing bushings or adapters to
adapt large hole abrasive wheels.
9. The wheel continues to rotate after the tool is switched
off .

Ensure that blotters are used when they are provided
with the bonded abrasive product and when they are
required.
Do not use separate reducing bushings or adaptors to
adapt large hole abrasive wheels.
For tools intended to be fi tted with threaded hole wheel,
ensure that the thread in the wheel is long enough to
accept the spindle length.
Do not use cutting off wheel for side grinding.
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.
