Additional Safety Warnings:

1. 

When using depressed centre grinding wheels, 

be sure to use only fiberglass-reinforced 

wheels.

2. 

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.

3. 

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.

4. 

Make sure the wheel is not contacting the 

workpiece before the switch is turned on.

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. 

Observe the instructions of the manufacturer 

for correct mounting and use of wheels. 

Handle and store wheels with care.

10. 

Do not use separate reducing bushings or 

adaptors to adapt large hole abrasive wheels.

11. 

Use only flanges specified for this tool.

12. 

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.

13. 

Check that the workpiece is properly 

supported.

14. 

Pay attention that the wheel continues to 

rotate after the tool is switched off.

15. 

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.

16. 

Do not use the tool on any materials contain-

ing asbestos.

17. 

Do not use cloth work gloves during operation.

 

Fibers from cloth gloves may enter the tool, which 

causes tool breakage.

SAVE THESE INSTRUCTIONS.

WARNING:

 

DO NOT let comfort or familiarity

strict adherence to safety rules for the subject 

product. MISUSE or failure to follow the safety 

rules stated in this instruction manual may cause
