WARNING Failure to follow correct working
practices can result in serious injury or death
Ensure that the workpiece is properly supported

curs, release the throttle and ease the wheel free.
Check the wheel is undamaged and properly se-
cured before continuing
Check that no bystanders are in the vicinity
►
Ensure that sparks do not cause a hazard to people
►
or materials
There is a risk of electrostatic discharge if the tool
►
is used on plastic and other non-conductive mater-
ials
