SANDING METAL
WIRE BRUSH OPERATIONS
WARNING!
• Never use your grinder without wearing eye protection.
• Never attach a wood cutting or carving blade of any type to
this angle grinder.
• Never use your grinder with guard removed.
• Failure to following this rule could result in serious personal
injury.
WARNING! If any of the following events occur during
normal operation, the power supply should be shut off at
once and then the tool should be inspected thoroughly and
repaired by a qualified person if necessary:
When sanding automobiles or appliances, wipe the metal
clean with a non-flammable solvent or commercial cleaner
to remove all wax and grease. By doing this first, the
sanding discs will sand better and last longer.
Wire brushes are intended to “clean” structural steel,
castings, sheet metal, stone and concrete.
They are used to remove rust, scale and paint.
For heavy duty work, use a coarse grit disc first. Follow-up
with a medium grit to remove scratches. To produce smooth
finish, use fine grit disc.
Avoid bouncing and snagging the wire brush,
especially when working corners, sharp edges
etc. This can cause loss of control and kick-back.
WARNING!
• The rotating parts get stuck of speed drops abnormally low.
• The tool shakes abnormally and accompanied by some
unusuaI noise.
• The motor housing gets abnormally Hot.
• Heavy sparks occurring around the motor area, and down
over the work area.
SANDING WOOD
When sanding wood the direction of the disc motion at the
contact point should parallel the grain as much as possible.
The rapid cut of discs and the swirl type scratch pattern they
occasionally create generally prohibit their use for producing
the final finish.
Scratches and circular marks are usually the result of using
too coarse a grit. When changing to a finer grit, move across
the sanding lines that were made by a previous coarser disc.
