WORKING HINTS FOR YOUR
ANGLE GRINDER
1. Always start at no load to achieve maximum
speed then start working.
2. Do not force the disc to work faster, reducing
the Disc's moving speed means longer
working time.
3. Always work with a 15-30 angle between disc
and workpiece. Larger angles will cut ridges
into the workpiece and affect the surface
finish. Move the angle grinder across and
back and forth over the workpiece.
4. When using a cutting disc never change the
cutting angle otherwise you will stall the
disc and angle grinder motor or break the
disc. When cutting, only cut in the opposite
direction to the disc rotation. If you cut in the
same direction as the disc rotation the disc
may push itself out of the cut slot.
5. When cutting very hard material best results
can be achieved with a diamond disc.
6. When using a diamond disc it will become
very hot. If this happens you will see a full
ring of sparks around the rotating disc. Stop
cutting and allow to cool at no load speed for
2-3 minutes.
7 . Always ensure the workpiece is firmly held or
clamped to prevent movement.
