SAFETY WARNINGS SPECIFIC FOR
GRINDING OPERATIONS
a. Do not “jam” a cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the
loading and susceptibility to twisting or snagging
of the wheel in the cut and the possibility of kickback
or wheel breakage.
b. Do not position your hand in line with and behind
the rotating wheel. When the wheel, at the point of
operation, is moving away from your hand, the
possible kickback may propel the spinning wheel and
the power tool directly at you.
c. When wheel pinched, snagged or when interrupting
a cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never attempt
to remove the cut-off wheel from the cut while
the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of wheel pinching or snagging.
d. Do not restart the cutting operation in the workpiece.
Let the wheel reach full speed and carefully reenter
the cut. The wheel may bind, walk up or kickback if
the power tool is restarted in the workpiece.
e. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near
the line of cut and near the edge of the workpiece on
both sides of the wheel.
f. Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.
g. Use only wheel types that are recommended
for your power tool and only for recommended
applications. For example: do not grind with the
side of a cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
h. For threaded abrasive cones and plugs use
only undamaged wheel mandrels with an
unrelieved shoulder flange that are of correct
size and length. Proper mandrels will reduce the
possibility of breakage.
EXTENSION CORDS
Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough
to carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss
of power and overheating. The following table shows
the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the cord.

1. ON/OFF switch and speed control
2. Spindle lock button
3. Collet nut
4. Umbrella nut
5. Air vents
6. Hanging loop
ASSEMBLY
ON/OFF and speed control switch (Fig. B)
Both the ON/OFF and speed control functions are controlled
by one switch (1) located on the top of the tool.
1. To turn the tool ON, slide the switch to the left.
2. To turn the tool OFF, slide the switch to the right.
3. To increase the speed, turn the tool ON and continue
to slide the switch to the left. To decrease the speed,
slide the switch to the right.
Changing the collet (Fig. C)
Some accessories require the use of different sized collets.
Collet sizes can be 1/8”, 3/32” and 1/16”. It is important to
ensure that the collet size matches the accessory.
Note: This tool includes the most commonly used collets:
1/8”, 3/32” and 1/16”.
Warning! Using a collet that is too large for the accessory
will result in the accessory possibly being thrown from
the tool causing serious injury.
1. Turn the tool switch OFF and remove the plug from
the power source.
2. Depress the spindle lock button (2) and slowly turn
the collet nut (3) until the spindle lock button locks
the spindle (Fig. C).
3. While holding the spindle lock button down, turn
the collet nut counter clockwise until it is removed.
4. Remove the collet (7) by pulling it out of the spindle.
