 Other personal 

protective equipment such as dust mask, gloves, helmet 

and apron should be worn when necessary. If in doubt,  

wear the protective equipment.

- 

Always  be  sure  that  the  tool  is  switched  off  and 

unplugged before carrying out any work on the tool.

- 

Accessories  must  be  rated  for  at  least  the  speed 

recommended on the tool warning label.

 Wheels and 

other accessories running over rated speed can fly apart 

and cause injury.

- 

Check the backing pad carefully for cracks, damage 

or  deformity  before  operation.

 Replace cracked, 

damaged or deformed pad immediately.

- 

Check that the workpiece is properly supported.

- Hold the tool firmly.

- Keep hands away from rotating parts.

-  Make  sure  abrasive  disc  or  wool  bonnet  is  not 

contacting the workpiece before the switch is turned 

on.

- When sanding metal surfaces, watch out for flying 

sparks.

 Hold the tool so that sparks fly away from you and

other persons or flammable materials.

-  Do  not  touch  the  workpiece  immediately  after 

operation;  it  may  be  extremely  hot  and  could  burn 

your skin.

-  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.

-  Do  not  use  the  tool  on  any  materials  containing 

asbestos.

- Do not use water or grinding lubricant.

-  Ventilate  your  work  area  adequately  when  you 

perform sanding operations.

- Always use the correct dust mask/respirator for the 

material and application you are working with.

-  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 main supply (use non metallic objects) and avoid 

damaging internal parts.
