• The direction of the cutting motion is important. Always feed the
cutting disc into the work so that it cuts in an upward direction. If you
do not do this It can result in the disc climbing out of the cut in an
uncontrolled manner and may lead to loss of control or serious injury.
• Whenever a new disc has been fitted, always run the grinder at no
load speed to check for irregularities before starting work.
GRINDING TIPS
• The key to efficient grinding is to control the pressure and surface
contact between the grinding disc and the workpiece.
• Flat surfaces are ground at an acute angle, usually 15 to 30 degrees
to the workpiece. Too great an angle causes concentration of
pressure on a small area which may gouge, or burn the workpiece.
• Allow the disc to reach full speed before grinding.
• Avoid overloading the angle grinder. If it becomes hot when being
used, allow it to run for a few minutes under no-load conditions.
