OPERATION

Before turning on machine, perform a dry run of the
cutting operation just to make sure that no problems will
occur when the cut is made.
 Start the machine by grasping the handle and fully
squeezing the on/off switch. Allow several seconds for
the wheel to build up to full speed before letting it come
into contact with the material to be cut.
 Once it reaches full speed slowly lower the “D” handle
until the cut-off wheel comes in contact with the material
being cut. Continue to use steady and even pressure to
obtain a uniform cut through the material. Never force the
wheel into the material being cut.

When the cut is complete, release the on/off switch and
allow the wheel to stop rotating before raising the wheel
out of material.
WARNING:
Do not touch the cut material until it cools or you
can be burned. Failure to heed this warning could
result in serious personal injury.
USING THE ADJUSTABLE FENCE
See Figure 8, page 20.
The adjustable fence is located at the rear of the cut-off
machine. As mentioned previously, it is used along with the
vise clamp to provide a clamp for holding the workpiece
securely when making cuts. It also makes the cut-off
machine more versatile.
The fence can be rotated to obtain cutting angles from 0°
to 45°. It also can be moved back to allow greater cutting
widths in thin stock, or forward to allow greater cutting
depths in tall or thick stock.
ADJUSTING THE CUTTING ANGLE
See Figures 8 - 10, page 20.

Unplug the cut-off machine.
 Loosen the miter lock handle by pushing down and rotating
counterclockwise. If it needs to be further loosened, pull
spring-loaded miter lock handle up and rotate it back to
the right. Release handle and allow it to seat (lock) in its
original position. Turn it to the left again until loose.

Rotate fence until the desired angle of cut on the scale
is aligned with the indicator in machine base.

Tighten the miter lock handle by turning the miter lock
lever to the right. If it needs to be tightened more, pull
the springloaded miter lock handle up and rotate it to the
left. Then release miter lock handle and allow it to return
to its original position. Rotate to the right again. Repeat
this process until miter lock handle is securely tightened.
This will secure the fence in place at desired angle. For
precise cuts, check the angle of cut for the fence against
the wheel with a protractor, bevel square, or other similar
device.
ADJUSTING THE WIDTH OF CUT
See Figure 10, page 20.
The adjustable fence can be repositioned by removing the
adjustment bolt.
 Unplug the cut-off machine.

To increase the width of cut of the cut-off machine, use
the arbor wrench to loosen and remove the adjustment
bolt securing the adjustable fence to machine base.
 Reposition the adjustable fence with one of three threaded
holes in back of the machine base.

Install adjustment bolt into machine base.

Check and adjust fence to desired cutting angle.

Tighten the adjustment bolt. The maximum width capacity
is approximately 8-1/4 in. at 90° and 5 in. at 45°.

Return arbor wrench to its storage area in base.
USING THE QUICK LOCK-RELEASE LEVER
AND VISE CLAMP
See Figures 11 - 12, page 21.
The quick lock-release lever engages the vise clamp to be
used along with the fence to provide a vise for securing the
workpiece to be cut. It also allows you to open and close
the vise quickly without repetitive turning of the vise crank
handle.
To loosen:

Unplug the cut-off machine.


Release tension on the vise clamp by rotating the vise
crank handle 1/2 to 1 turn counterclockwise.


Lift up the quick lock-release lever as shown in fig-
ure 12 and pull back on vise crank handle to slide open
the vise.
To tighten:

Unplug the cut-off machine.
  Push the vise crank handle forward to slide the vise clamp
against the workpiece.


Rotate the quick lock-release lever forward and push
down as shown in figure 12 to engage its threads with
the vise screw.


Rotate the vise crank handle clockwise to tighten the vise
clamp against the workpiece.
