2. When the cut-off wheel contacts the mate-
rial, gently press down the handle further and
start cutting.
3. When cutting (or designated slotting) is
completed, raise the handle and restore it to
its original position.
4. At the termination of each cutting process,
turn OFF the switch to stop rotation and pro-
ceed with the subsequent cutting job.
WARNING: Confirm that the trigger switch
is turned OFF and that the power plug has
been removed from the receptacle, whenever
the tool is not in use.
CAUTION: Increased pressure on the handle
will not increase the cutting speed. On the
contrary, too much pressure may result in over-
load of the motor and/or decreased cutting ef-
ficiency.
CUTTING AT ANGLES
The machine permits cutting at angles of 45°.

Loosen the two M10 hex socket head bolts on
the vise, then set the working surface on the
vise-jaw at any angles of 0°, 30° or 45°.
Upon completion of setting, securely tighten
the two M10 hexagon socket head bolts.
MOVING THE STATIONARY VISE-JAW
The vise opening is set at the maximum of
6-11/16" (170 mm) when shipped from the fac-
tory. In case an opening more than 6-11/16"
(170 mm) is required, move the vise-jaw to
the position shown by the chain line, after un-
screwing the two bolts.

CUTTING WITH A REDUCED DISC
When the cut-off wheel has a reduced outer
diameter, insert between the vise (A) and (B) a
metallic block slightly smaller than the dimen-
sion of workpiece being cut to use the cut-off
wheel economically.

MAINTENANCE

REMOVAL / INSTALLATION OF WHEEL
TO REMOVE
• Unplug the cut-off machine.
• Push down on machine arm and remove
transport chain from hook on motor housing
to release machine arm.
• Raise machine arm to its full raised posi-
tion. Be cautious when raising, machine arm is
spring loaded.
• Rotate lower wheel guard upward, exposing
the hex head bolt that secures abrasive wheel
to wheel arbor.
• Depress the spindle lock button and rotate
bolt until spindle locks, preventing shaft from
rotating.
• Using the hex wrench provided, loosen and
remove bolt.
NOTE: Bolt has right hand threads. Turn bolt
counterclockwise to loosen.
• Remove outer washer, outer flange, spacer,
and wheel. Do not remove inner flange or in-
ner washer. Removal of these two parts are not
required for wheel changes.
WARNING: If inner flange or inner washer
has been removed, replace both before placing
wheel on spacer and wheel arbor. Failure to do
so could cause an accident since wheel will not
tighten properly.
TO INSTALL
• Unplug the cut-off machine.
• Inspect the replacement wheel for defects
