OPERATION
WARNING:
Do not allow familiarity with tools to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict severe injury.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1. Failure to do
so could result in objects being thrown into your
eyes, resulting in possible serious injury.
WARNING:
Do not use any attachments or accessories not
recommended by the manufacturer of this tool.
The use of attachments or accessories not recom-
mended can result in serious personal injury.
WARNING:
Do not attempt to cut wood or masonry with this
cut-off machine. Never cut magnesium or mag-
nesium alloy with this machine. Failure to comply
could result in serious personal injury.
WARNING:
Never install any wood cutting blade on this
machine. The cut-off machine is properly guarded
only for cutting metal with an abrasive wheel.
Failure to comply could result in serious personal
injury.

Always use the vise clamp on the cut-off machine
to prevent accidents that could result in possible
serious personal injury.
APPLICATIONS
You may use this tool for the purposes listed below:
 Cutting all types of metals such as 2 in. x 6 in. steel
framing studs
 Cutting hard metal iron stock such as square bar stock
and angle iron
 Cutting metal tube and pipe stock
POWER SUPPLy
Before operating the cut-off machine, check the power
supply and make sure it meets the requirements listed on
the tool's data plate. A substantial voltage drop will cause a
loss of power and machine overheating.
Common causes of power loss and machine overheating are
insufficient extension cord size and multiple tools operating
from the same power source.
ON/OFF SWITCH
To turn the cut-off machine ON, depress the on/off switch
located in the handle portion of the machine arm.
To turn it OFF, release the on/off switch.
CUTTING WITH THE CUT-OFF MACHINE
See Figures 7-8, page 19.
A cut-off is made by cutting across the width of the material.
A straight cross cut is made with the adjustable fence set at
the zero degree position. Angled cut-offs are made with the
adjustable fence set at some angle other than zero.
 Loosen the miter lock handle securing the fence.
 Rotate the adjustable fence to the desired angle.
 Retighten miter lock handle securing fence.
WARNING:
To avoid serious personal injury, always tighten
vise adjustment bolt securely before making a cut.
Failure to do so could result in movement of the
material while making a cut.
 Place the material flat on the machine base with one
surface securely against the adjustable fence.
 Align cutting line on the material with the edge of the
abrasive wheel.
 Push in the vise crank handle to set the vise clamp against
the material. Turn the vise crank handle 1/2 to 1 turn clock-
wise to securely clamp the material to the fence.
 Firmly secure the material to be cut using the machine's
vise (adjustable fence and vise clamp).
 When cutting long pieces, support the opposite end of
the material with a roller stand or with a work surface level
with the machine base.
WARNING:
Never perform any cutting operation freehand (with-
out placing material in the vise). Material will get hot
during cutting operation. Keep hands off of metal
being cut to avoid serious personal injury.
