6. OPERATING INSTRUCTIONS

6.1. The grinding disc should be replaced when the diameter of the disc reaches 85mm.
6.2. Hold the grinder in front and away from you with both hands, keeping the grinding disc away from
the work piece.
6.3. Turn on the grinder and let motor build up to full speed. Gradually lower the grinder until the
grinding disc comes into contact with the work piece.
6.4. Move the grinder back and forth or up and down over the work piece at a steady, consistent
speed. Keep the grinder moving to prevent excessive amounts of material being removed from a
single place?
6.5. If the grinder is held in one place for too long, it will cut grooves into the work piece. Do not hold
the grinder at too sharp an angle as it will gouge the work piece because of too much pressure IN
one area.
6.6. Do not apply excessive pressure whilst grinding.
6.7. Usually the weight of the grinder alone is adequate for most grinding jobs. Use light pressure when
grinding jagged edges or where there is a risk for the grinder to snag.
6.8. When grinding lift the grinder away from the work piece before turning the grinder off.
6.9. When cutting turn the grinder off before removing disc from work piece, once it has stopped
remove it from the work piece.
