Additional Safety Warnings: 

17. 

When using depressed centre grinding wheels, 
be sure to use only fiberglass-reinforced wheels. 

18. 

NEVER USE Stone Cup type wheels with this 
grinder.

 This grinder is not designed for these 

types of wheels and the use of such a product may 
result in serious personal injury. 

19. 

Be careful not to damage the spindle, the 
flange (especially the installing surface) or the 
lock nut. Damage to these parts could result in 
wheel breakage. 

20. 

Make sure the wheel is not contacting the 
workpiece before the switch is turned on. 

21. 

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. 

22. 

Use the specified surface of the wheel to 
perform the grinding. 

23. 

Do not leave the tool running. Operate the tool 
only when hand-held. 

24. 

Do not touch the workpiece immediately after 
operation; it may be extremely hot and could 
burn your skin. 

25. 

Observe the instructions of the manufacturer 
for correct mounting and use of wheels. 
Handle and store wheels with care. 

26. 

Do not use separate reducing bushings or 
adaptors to adapt large hole abrasive wheels. 

27. 

Use only flanges specified for this tool. 

28. 

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. 

29. 

Check that the workpiece is properly supported. 

30. 

Pay attention that the wheel continues to 
rotate after the tool is switched off. 

31. 

If working place is extremely hot and humid, 
or badly polluted by conductive dust, use a 
short-circuit breaker (30 mA) to assure 
operator safety. 

32. 

Do not use the tool on any materials 
containing asbestos. 

33. 

When use cut-off wheel, always work with the 
dust collecting wheel guard required by 
domestic regulation. 

34. 

Cutting discs must not be subjected to any 
lateral pressure. 

SAVE THESE INSTRUCTIONS.
