     WARNING:  

To reduce the risk 

of injury, electric shock and damage to 

the tool, before starting any work, check 

to determine if utility lines electricity, gas 

or water supply lines are hidden in the 

work area.

     WARNING:  

Firmly grasp the 

body of the tool and the side handle 

before starting.

GRINDING APPLICATION (Fig. 6)

 

 Secure small workpieces in a vise or 

clamp them to a workbench.

 

 The key to efficient operation is controlling 

the pressure and surface contact between 

the grinding wheel and workpiece. 

 

 Start the angle grinder and let the motor 

and grinding wheel build up to full speed. 

Gradually lower the angle grinder until the 

grinding wheel contacts the workpiece.

 

 When grinding, keep a 10-15°angle 

between the wheel and the workpiece; 

 

 Move the machine back and forth with 

moderate pressure to avoid discoloring 

the workpiece, overheating the workpiece 

and creating ridges.

 

 Remove the tool from the workpiece 

before turning the tool off. Allow the tool 

to stop completely before setting it down.

 

 Never use a cut-off wheel to grind a work 

piece. 

 

 Always hold the tool properly so that 

sparks and grinding dust fly away from 

the body.

     WARNING: 

 Sparks are 

generated when grinding metal. Take care 

that no combustible material presented in 

the area of flying sparks.

impact to the tool and keep it from oil and 

grease.

screws loosen, tighten them immediately, 

to avoid serious accident.

debris from vents. Keep the tool clean, dry 

and free of oil or grease.
