Start Up
The angle grinder is a handheld power tool used for grinding and cutting steel, pipes, angle iron, bricks, tiles, stone,
and/or ceramic pieces; for removing burrs from metal surfaces, and for leveling and smoothing welds.
Start up
• Press the switch precisely into the pressure position (A). Then,
push slightly downward and direct the pressure forward (B)
without releasing it. To keep it locked, release the switch.
• To interrupt its operation, press in the pressure position (A) and
then release the switch.
Holding the tool properly
Always hold the tool with both hands. One hand holding
the handle and the other the auxiliary handle. Be careful not
to block the ventilation slots.
• Grinding:
For optimal results, hold the tool at an angle of 15° to 30°
in relation to the workpiece. Move it back and forth with a
gentle, consistent pressure. This technique prevents the
workpiece from overheating, discoloration, and the
formation of any edges.
• Cutting:
Do not press, tilt, or swing the tool. Work at a moderate
speed.
The disc should always rotate in the opposite direction of
the cutting movement, never in the other direction, as there
is a risk of the tool being thrown uncontrollably. When
cutting hard stones, it is advisable to use a diamond cutting
disc.
Useful tips
• Work with the disc in the correct position to avoid
damage.
• Press on the workpiece with a force less than the weight
of the tool to prevent overloading and damaging the motor
and disc.
• After installing a new disc, allow the disc to rotate without
working for at least one minute. In case it vibrates, replace it
immediately.
CAUTION
• Avoid working with wood or soft metals
like lead, as these materials quickly saturate the disc and
render it useless.
