maximum  control  over  kickback  or  torque  reaction  during  start-up.  The 

operator  can  control  torque  reactions  or  kickback  forces,  if  proper 

precautions are taken. 

b)  Never place your hand near the rotating accessory.

 

Accessory may kickback 

over your hand. 

c)  Do not position your body in the area where power tool will move if kickback 

occurs.

 

Kickback  will  propel  the  tool  in  direction  opposite  to  the  wheel’s 

movement at the point of snagging. 

d)  Use  special  care  when  working  corners,  sharp  edges  etc.  Avoid  bouncing 

and  snagging  the  accessory.

 

Corners,  sharp  edges  or  bouncing  have  a 

tendency  to  snag  the  rotating  accessory  and  cause  loss  of  control  or 

kickback.   

e)  Do  not  attach  a  saw  chain  woodcarving  blade  or  toothed  saw  blade.  Such 

blades create frequent kickback and loss of control. 

 
Additional Safety Warnings for Grinding Operation 

a)  Use  only  wheel  types  that  are  recommended  for  your  power  tool  and  the 

specific guard designed for the selected wheel. Wheels for which the power 

tool was not designed cannot be adequately guarded and are unsafe. 

b)

 

The grinding surface of centre depressed wheels must be mounted below the 

plane of the guard lip. An improperly mounted wheel that projects through the 

plane of the guard lip cannot be adequately protected.

 

c)  The guard must be securely attached to the power tool and positioned for 

maximum safety, so the least amount of wheel is exposed towards the 

operator. The guard helps to protect operator from broken wheel fragments 

and accidental contact with wheel and sparks that could ignite clothing. 

d)  Wheels must be used only for recommended applications. For example: do 

not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended 

for peripheral grinding, side forces applied to these wheels may cause them 

to shatter. 

e)  Always use undamaged wheel flanges that are of correct size and shape for 

your selected wheel. Proper wheel flanges support the wheel thus reducing 

the possibility of wheel breakage. Flanges for cut-off wheels may be different 

from grinding wheel flanges. 

f) 

Do not use worn down wheels from larger power tools. Wheel intended for larger 

power tool is not suitable for the higher speed of a smaller tool and may burst. 

SAVE THESE INSTRUCTIONS. 

WARNING! 

MISUSE  or  failure  to  follow  the  safety  rules  stated  in  this  instruction  manual 

may cause serious personal injury. 

 

 

INSTRUCTIONS FOR OPERATION 

Installing or Adjusting Wheel Guard 

CAUTION: 

 Always  be  sure  that  the  tool  is  switched  OFF  and  unplugged  before  installing  or 

removing the wheel guard. 

Wheel guard is a device to protect operator 

from  injuries  if  the  wheel  breaks  during 

operation. Before operation, make sure the 

wheel  guard  is  tightly  installed.  By  slightly 

loosening  the  setting  screw,  the  wheel 

guard can be turned and set at any desired 

angle 

for 

maximum 

operational 

effectiveness.  Ensure  that  the  setting 

screw is thoroughly tightened after adjusting the wheel guard.
