To reduce the risk of injury and to ensure maximum control during use, hold the tool with both hands 
while the tool is in operation. 
 

OPERATION:                                                                                             

 

Operating the on/off switch 

1.  To turn the Angle Grinder on, slide the on/off switch forward to the on position”1” (

Fig.X

2.  To turn the Angle Grinder off, slide the on/off switch towards the rear of the Angle Grinder to 

the off position “0”.

Safe use and operation of the Angle Grinder 

1.  Do  not  expose  the  tool  to  rain  or  snow.  Do  not  use  the  tool  in  damp  locations  or  in  an 

environment with explosive or corrosive gas. 

2.  Keep your work area well lit. 
3.  Make sure you are well balanced when using the tool and you have secure footing. Do not 

use the tool when you are tired. 

4.  Keep long hair away from the Angle Grinder. 
5.  Always inspect the Angle Grinder before use. 
6.  Make sure the disc is not contacting the work piece when the switch is turned on. 
7.  Keep the guard in place. 

8. 

Adjust  the  position  of  the  guard  to  best  shield  the  user  from  sparks  according  to  the 
application. 

Fig H&I 

9.  Use  only  discs  having  a  maximum  operating  speed  at  least  as  high  as  “No  Load  Speed” 

marked on the nameplate. 

10. Check  the  disc  carefully  for  cracks  or  damage  before  operation.  Replace  cracked  or 

damaged discs immediately. 

11. Be careful not to damage the spindle or either of the disc flanges. Damage to these parts 

could result in disc breakage. 

12. Hold the tool firmly. 
13. Before  using  the  tool  on  an  actual  work  piece,  let  it  run  for  a  while.  Watch  for  vibration  or 

wobbling that could indicate poor installation of the disc or a poorly balanced disc. 

14. Use only discs designed for each specified function and purpose. Do not use cutting discs 

for grinding or metal wheels on masonry. 

15. Watch out for flying sparks. Hold the tool at an angle of approximately 15

°

-30

°

 to the work 

piece surface. 

Fig J

 

16. To prevent a new grinding disc from digging in to the work piece, initial grinding should be 

conducted by drawing the Angle Grinder towards yourself. Once the leading edge of the disc 
is worn a little, it’s possible to grind in any direction. 

17. It  should  never  be  necessary  to  force  the  tool.  If  the  rotational  speed  drops  abnormally, 

pressure should be released immediately. Little more than the weight of the tool should be 
applied. Forcing and excessive pressure can cause dangerous disc breakage or damage to 
the tool. 

 

MAINTENANCE 

 

Maintain your Angle Grinder. 

It is recommended that the general condition of any Angle 

Grinder be examined before it is used. Keep your Angle Grinder in good repair by adopting a
