5.
Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
6.
Use the specified surface of the wheel to per-
form the grinding.
7.
Do not leave the tool running. Operate the tool
only when hand-held.
8.
Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
9.
Do not touch accessories immediately after
operation; it may be extremely hot and could
burn your skin.
10. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
11.
Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
12. Use only flanges specified for this tool.
13. For tools intended to be fitted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
14. Check that the workpiece is properly
supported.
15. Pay attention that the wheel continues to
rotate after the tool is switched off.
16. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure opera-
tor safety.
17. Do not use the tool on any materials contain-
ing asbestos.
18. When use cut-off wheel, always work with
the dust collecting wheel guard if required by
domestic regulation.
19. Cutting discs must not be subjected to any
lateral pressure.
20. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
21. Before operation, make sure that there is no
buried object such as electric pipe, water pipe or
gas pipe in the workpiece. Otherwise, it may cause
an electric shock, electrical leakage or gas leak.
22. If a blotter is attached to the wheel, do not
remove it. The diameter of the blotter must be
larger than the lock nut, outer flange, and inner
flange.
23. Before installing a grinding wheel, always
check that the blotter part does not have any
abnormalities such as chips or cracks.
24. Tighten the lock nut properly. Overtightening
the wheel can cause breakage and insufficient
tightening can cause fluttering.
