vent the spindle from moving.
8. While pressing the
spindle-lock button,
tighten the threaded
outer flange by turning
it clockwise using the
wrench.
To remove a disc:
1. Disconnect the plug from the electrical outlet.
2. While pressing the spindle-lock button, loos-

OPERATION INSTRUCTIONS

1. For best control, hold the angle grinder firmly
with one hand gripping the side handle and the
other gripping the rubber-coated grip on the
body of the angle grinder.
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
12
workpiece. It will decrease the life of the trig-
ger switch and could cause damage to the work-
piece.
NOTE: Be prepared for a stream of sparks when
the disc touches metal.
4. Tilt the angle grinder at a 15º to 30º 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 over-
load the motor, cause a drop in the speed and
put dangerous stress on the grinding disc, pos-
sibly causing breakage and injury.
6. When using a new grinding disc, do not move
the disc in a forward direction (A) on the work-
piece. 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" diam-
eter. 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 binding
of moving parts, or any other conditions that
may affect the operation. If abnormal vibration
or noise occurs, turn the tool off immediately
and have the problem corrected before further
use.
CUTTING
The finished will be perfect if you make it with
a straight angle and with a middle pressure. If
you apply too much pressure, it may result in the
collapse of the disc and can cause severe injuries
to the operator and bystanders.
Don't press the cutting disc side. When making
long cuts, outlined or channel cuts, always starts
by the shorter work piece section.
