General Operation
TO PREVENT SERIOUS INJURY:
DO NOT OPERATE WITH ANY GUARD DISABLED,
DAMAGED, OR REMOVED. Moving guards must
move freely and close instantly.
1. Raise the Saw Head Assembly by pushing down on
the Handle and pulling out the Head Lock-Down Pin.
2. Using the Vise, secure the workpiece and,
if necessary, adjust the angle of the cut.
3. Plug the Power Cord into the nearest
120 VAC, grounded electrical outlet.
4. Grip the Saw Handle and squeeze the Trigger to start
the Saw. Allow the Cut-Off Wheel to attain full speed.
5. With one hand on the Handle and the other
hand clear, slowly bring the Cut-Off Wheel
down onto the workpiece, letting the Saw
do the work. Do not apply excessive force.
6. If the Cut-Off Wheel does not cut all
the way through the workpiece:
a. Raise the Saw Head and release the Trigger.
b. Unplug the unit.
c. Wait until the Cut-Off Wheel comes to a full stop.
d. Remove the workpiece.
e. Set the depth adjustment to a deeper setting.
See Using the Depth Stop on page 9.
f. After adjusting the depth, bring the Saw
Head all the way down to make sure the
Cut-Off Wheel doesn’t contact the Base.
g. If it does contact any part of the Base,
re-adjust the depth so it doesn’t.
h. Repeat the cutting process
starting with step 1 above.
7. When the cut is completed, raise the
Saw Head and release the Trigger.
CAUTION! Do not attempt to remove the workpiece
until the Cut-Off Wheel has stopped moving.
8. After the Wheel has stopped turning, release the
Vise and remove the workpiece from the Saw.
9. To prevent accidents after use, turn off the tool,
disconnect its power supply, and lock it down by
pushing the Saw Head down as far as it will go
and pushing in the Head Lock-Down Pin. Clean,
then store the tool indoors out of children’s reach.
