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. 

Watch out for flying sparks. Hold the tool so 
that sparks fly away from you and other 
persons or flammable materials. 

24. 

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

25. 

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

26. 

Always be sure that the tool is switched off 
and unplugged or that the battery cartridge is 
removed before carrying out any work on the 
tool. 

27. 

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

28. 

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

29. 

Use only flanges specified for this tool. 

30. 

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. 

31. 

Check that the workpiece is properly 
supported. 

32. 

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

33. 

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. 

34. 

Do not use the tool on any materials 
containing asbestos. 

35. 

Do not use water or grinding lubricant. 

36. 

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. 

37. 

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

38. 

Cutting discs must not be subjected to any 
lateral pressure. 

SAVE THESE INSTRUCTIONS. 

 

WARNING: 

DO NOT let comfort or familiarity with product 
(gained from repeated use) replace strict adherence 
to safety rules for the subject product. MISUSE or 
failure to follow the safety rules stated in this 
instruction manual may cause serious personal 
injury.

battery charger, (2) battery, and (3) product 
using battery. 

2. 

Do not disassemble battery cartridge. 

3. 

If operating time has become excessively 
shorter, stop operating immediately. It may 
result in a risk of overheating, possible burns 
and even an explosion. 

4. 

If electrolyte gets into your eyes, rinse them 
out with clear water and seek medical 
attention right away. It may result in loss of 
your eyesight. 

5. 

Do not short the battery cartridge: 

(1) 

Do not touch the terminals with any 
conductive material. 

(2) 

Avoid storing battery cartridge in a 
container with other metal objects such as 
nails, coins, etc. 

(3) 

Do not expose battery cartridge to water 
or rain. 
A battery short can cause a large current 
flow, overheating, possible burns and 
even a breakdown. 

6. 

Do not store the tool and battery cartridge in 
locations where the temperature may reach or 
exceed 50

C (122
