than the speed shown on the grinder's name-
plate.
NOTE: The maximum disc thickness is 1/4"
(6,5mm), and the spindle opening is 7/8"
(22,3mm).
5. Place the disc on the spindle.
6. Replace the outer flange, with the flat side
of the flange facing the disc.
7. Press the spindle-lock button (6) in order to
prevent the spindle from moving.

OPERATION INSTRUCTIONS

1. For best control, hold the angle grinder firm-
ly with one hand gripping the side handle and
the other gripping the rubber-coated grip on
the body of the angle grinder.
12
NOTE: The starting torque creates a sudden
jerk.
2. Always position the guard so that the ex-
posed grinding disc is pointing away from the
operator.
3. After starting the tool, apply the grinding
disc to the workpiece.
NOTE: Do not turn the angle grinder "ON"
or "OFF" while the grinder is in contact with
the workpiece. It will decrease the life of the
trigger switch and could cause damage to the
workpiece.
NOTE: Be prepared for a stream of sparks when
the disc touches metal.
4. Tilt the angle grinder at a 15º to30º angle for
easy handling and smooth grinding.
This will make it easier to remove the disc from
the workpiece, and will prevent unnecessary
overloading.
5. Apply the grinding disc to the work surface
using light, steady pressure for grinding effi-
ciency.
WARNING: Do not apply unnecessary pres-
sure. The weight of the tool applies adequate
pressure. Excessive or sudden pressure will
overload the motor, cause a drop in the speed
and put dangerous stress on the grinding disc,
possibly causing breakage and injury.
6. When using a new grinding disc, do not
move the disc in a forward direction (A) on the
workpiece. Doing so will cause the edge of the
disc to cut into the surface of the workpiece.
While grinding, the direction of movement
should be backward, toward the operator (see
image above).
WARNING: Do not use a disc with a centre
indentation after it has been worn to a 3" di-
ameter. The continued use of a worn-out disc
may result in disc explosion and serious injury.
WARNING: Before each use, inspect the an-
gle grinder, the ON/OFF trigger switch, and the
cord for any damaged, missing, or worn parts.
Check for loose screws, misalignment or bind-
ing of moving parts, or any other conditions
that may affect the operation.
