Tilt the grinder at a correct angle of 10º to 15º for easier gripping and smooth grinding. This
increases the removability of the disc and prevents unnecessary overload.
Apply gentle but persistent pressure to the work surface on the disc for increased grinding e -
ciency. It will never be necessary to force the machine. The weight of the machine applies ade-
quate pressure. Sudden or excessive pressure overloads the motor, which would cause a drop in
its speed, in this way the disc would be tensioned and could break.
When using a new disc, DO NOT move the disc forward on the workpiece. This will cause the
edge of the disc to cut on the surface of the workpiece. Move the grinder toward you while you
are grinding.
Do not use a center depressed disc that is 3 "in diameter. Continuing to use a disc in that state can
be dangerous and result in the disc exploding and serious personal injury.
Note: Do not turn the machine on or o when the grinder is in contact with the workpiece, this
will shorten the life of the disc, causing damage to the workpiece.
Note: Be prepared for a lot of sparks when the disc touches the metal.
MAINTENANCE
WARNING
It is recommended that all repairs or replacements be carried out by a quali ed technical service.
WARNING
Before cleaning or performing any maintenance, the tool must be disconnected from the power
source. The most e ective cleaning method may be blowing with dry compressed air. Always
wear protective glasses when cleaning the machine with compressed air.
Before each use, inspect the grinder, switch, and cord for damage. Check for damaged, missing,
or worn parts. Check for missing screws, misalignment or loose moving parts, or any other condi-
tion that may a ect operation.
If abnormal vibration or abnormal noise occurs, turn o the machine immediately and resolve
this problem before using it again.

CARBON BRUSHES

The brushes and collectors of the tool should be examined frequently. Its good contact makes
the tool energetic. When the spark around the collector gets bigger, the carbon brushes should
be changed.
