  Always use the auxiliary handle and ensure a good grip 

on the grinder housing with one hand and the handle with 

the other hand before proceeding with any work. 

  Make sure that the disc is not in contact with the work 

when you start the grinder.

  Be careful not to damage the spindle or either of the disc 

flanges. Damage to these parts could result in  

disc breakage.

  Do not press the spindle lock button whilst the  

spindle is turning.

  Only use good quality grinding and cut off discs. Cheap 

poor quality discs tend to glaze up which loads the 

motor and can damage it. Use discs for their designated 

purpose only. For instance, do not use cutting discs for 

grinding or metal wheels on masonry.

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

approximately 15º to 30º to the work piece surface.

  Let the disc do the grinding or cutting at a reasonable 

feed, as overloading will occur if too much pressure is 

applied and the disc slows resulting in inefficient cutting 

and possible damage to the motor. 

  When using the grinder, use safety equipment including 

safety goggles or shield, ear protection, dust mask and 

protective clothing including safety gloves. 

ALWAYS WEAR EYE PROTECTION
Wear goggles
Wear hearing protection
Wear a breathing mask

Accessories

The GMC AG230M Angle Grinder is supplied with the 

following accessories as standard:

  Pin wrench

  Instruction manual

Unpacking 

Due to modern mass production techniques, it is unlikely 

that your GMC Power Tool is faulty or that a part is missing. 

If you find anything wrong, do not operate the tool until the 

parts have been replaced or the fault has been rectified. 

Failure to do so could result in serious personal injury.
