OPERATING THE TOOL
Following a few simple tips will reduce wear
on the tool and it will reduce the chance of
injury to the operator.
This machine
WARNING
!
intended to be used with
Wet Diamond Wheels. Using water or other
liquid coolants with this machine may result
in electrocution or shock. Use of Dry
Diamond Wheels is acceptable.
APPLICATIONS
This tool is intended for cutting the following
materials.
1/8˝ maximum thick sheet steel.
Concrete cinder blocks and bricks.
Reinforcing rod-generally under 3/4˝
diameter.
1/8˝ concrete wire mesh.
Corrugated floor and ceiling forms (concrete
forms).
Electrical conduit 1/8˝ wall thickness.
1/8" maximum thick structural forms such
as: channels, angles, plate and etc.
ABRASIVE WHEELS
Use aluminum oxide wheels for cutting
metal.
Use silicon carbide wheels for cutting
masonry.
Use dry diamond wheels for cutting
concrete. Dry diamond wheel stay cooler,
clogs less and last longer.
1 Before running a cut-off machine, inspect
the cutting wheel for chips or cracks.
Replace bad wheels immediately. New
wheels should be run in at no load or at least
a minute in direction away from the presence
of other people. Imperfect wheels will
normally break apart during this time.
2. An abrasive cut-off machine must NEVER
be operated without the attached guard
secured in place. The guard should be
rotated into the position where maximum
protection is provided for the operator from
sparks and wheel periphery.
3. Proper apparel for operating the tool
includes eye protection, leather gloves, dust
mask and a shop apron.
4. With the tool in the "OFF" position,
become familiar with handling the tool.
Control the head of the tool with the side
handle. Control the cutting edge of the
wheel with the switch handle. Always use
both hands when operating the tool.

5. Never drop the tool. Set the tool down
gently, but never on the wheel.
6. CUTTING CONCRETE will throw large
amounts of dust into the surrounding
area.
is not
Protective dust masks are strongly
recommended for breathing protection for
the operator and other nearby workers.
7. Due to the size and weight of the cut-off
machine it is not recommended to be used
overhead or in any position that would not
allow proper control. Ladders or scaffolding
are not considered solid support structures.
8. Avoid overloading tool. Do not allow the
wheel to bind or stall. Many cuts, especially
into solid concrete, require successive
passes. Do not expose any more abrasive
wheel than necessary to cut with normal
amount of pressure applied to tool. Begin
cutting from the edge of the material,
starting with about 1" wheel exposed. Do
not force the tool; load it normally.
Depending on material hardness and
density, make successively deeper passes
until cut is complete.
FIRE FORWARD/FIRE REVERSE
Models 1364 & 1365 are shipped with
abrasive Cutoff Machine set up in fire
forward position. Both can be easily
converted to fire reverse position without
any additional accessories.
Fire forward position directs sparks, dust
and debris away from the operator.
Fire reverse position changes direction of
rotation so sparks, dust and debris are
thrown toward the operator.
The proper fire position depends on how the
tool is being held, direction of travel, and
personal preference. Always remember the
reason for this feature is to direct sparks,
dust and debris away from the operator.
FIRE REVERSE APPLICATIONS
Below are a few examples of when you may
want to change your tool to the reverse fire
position.
• When cutting in a vertical position to direct
debris toward your feet instead of you face.
• When pulling the tool through the
workpiece instead of pushing the tool.
• When working in confined areas close to a
wall.
• Personal comfort.
