before starting to grind.
Hold your angle grinder with one hand on the
main handle and other hand firmly around the
auxiliary handle.
Always position the guard so that as much of the
exposed disc as possible is pointing away from
you.
Be prepared for a stream of sparks when the disc
touches the metal.
For best tool control, material removal and
minimum overloading, maintain an angle
between the disc and work surface of
approximately 150 -300 when grinding.
Use caution when working into corners as
contact with the intersecting surface may cause
the grinder to jump or twist.
When grinding is complete allow the workpiece
to cool. Do not touch the hot surface.

8. CUTTING
WARNING! For cutting metal, always work
with the wheel guard for cutting.
When cutting, do not press, tilt or oscillate the
machine. Work with moderate feed, adapted to
the material being cut.
Do not reduce the speed of running down cutting
discs by applying sideward pressure.
The direction in which the cutting is performed is
important.
The machine must always work in an up-grinding
motion. Therefore, never move the machine in
the other direction! Otherwise, the danger exists
of it being pushed uncontrolled out of the cut.
9.OVERLOAD
Overloading will cause damage to the motor of
your angle grinder. This can happen if your angle
grinder is subjected to heavy use for prolonged
periods of time.
Do not in any circumstances, attempt to exert too
much pressure on your angle grinder to speed
up your work.
If your angle grinder becomes too hot, run you
angle grinder under no load for 2-3 minutes until
15 -30
