Assembly
Attaching Cut-off Wheel
Disconnect the power
cord from the power
source before making any assembly, ad-
justments or changing accessories.
Such
preventive safety measures reduce the risk of
starting the tool accidentally.
Use only diamond seg-
mented wheels less than
3/8” (10mm) thick, having a negative rake
angle and no more than 3/8” (10mm) gap
between the segments.
1. Tip the tool back with the guard facing up.
2. Press the lock button and turn the wheel bolt
using the 1/2” slot of the wrench until lock
button engages. The shaft is now locked.
Continue to depress button, turn wrench
clockwise and remove WHEEL BOLT and
OUTER WASHER (Fig. 2).
3. Make sure that the arrow on the cut-off
wheel is pointing in the same direction as
the arrow on the upper guard.
4. Slide cut-off wheel into the upper guard and
mount it against the INNER WASHER on
the shaft. Be sure that the large diameter of
the INNER and OUTER washers lay flush
against the cut-off wheel.
5. Reinstall OUTER WASHER. First tighten
WHEEL BOLT finger tight, then TIGHTEN
WHEEL BOLT 1/8 TURN (45˚) WITH THE
WRENCH PROVIDED.
Do not use wrenches with longer handles,
since it may lead to over tightening of the
wheel bolt.
