U.S.SAWS AIR POWERED BELLY SAW
The U.S.SAWS Air Powered Belly Saw is designed to provide a
safe alternative to other cutting methods that can be difcult
and dangerous because of the subgrade location of pipes. The
key factor that provides ease and safer operation is that the
tool is strapped to the pipe and is simply drawn around the
pipe creating a straight and efcient cutting process. Other Key
factors are that because of the use of air or hydraulic power
sources the tools can run in the wet conditions without failure.
Saw cuts easily through PVC‚ HDPE‚ ductile iron‚ cast iron and
more thanks to its Tiger Tooth blade. The saw’s protective
clamshell design shields you from the blade until the time of the
cut. Once contact is made‚ four spring-loaded wheels help guide
the saw for a straight cut.
Package Includes: Belly Saw, Tiger Tooth Blade, Strap Assembly,
Whip Hose with Oiler, (2) Wrenches, (1) Quart Ice Free Oil &
Storage Bag
Features:
• Provides the safest and most accurate cut
• Designed to cut the underside of pipes safely with minimal
clearance
• These saws will cut through any type of pipe when coupled
with our Tiger Tooth blade
• Models offered for cutting pipes form 8” to 60” in diameter
• Clamshell design shields blade until time of cut
• 4 spring-loaded wheels help operator to cut straight and
square
• Ideal for tight spaces

OPERATION
The US Saws Belly Saw is designed to provide a safe alternative to
other cutting methods that can be di󰀩cult and dangerous because of the
subgrade location of pipes. The key factor that provides ease and safer
operation is that the tool is strapped to the pipe and is simply drawn
around the pipe creating a straight and e󰀩cient cutting process. Other
Key factors are that because of the use of air or hydraulic power sources
the tools can run in the wet conditions without failure. To provide the
most accurate and time e󰀩cient cutting follow the procedures below.
The belly saw was originally designed to cut the bottom ¾ of a pipe. Many operators have determined that the
belly saw provides simple and easy cutting of the entire pipe. In order to ensure an accurate cut that nishes
where the cut begins several procedures must be taken. Once all job site safety conditions have been met
pressurize the tools lines. Ensure safety clips are used where required so lines do not disconnect accidentally.
One should take care to make sure proper clearance has been provided on all sides of the line being cut. If an
object creates interference during the cutting process there will be di󰀩culty completing the cut accurately. The
pipe must also be cleaned of rust, dirt, and unusually rough surface obstructions.
1. With the roller strap removed from the belly saw plunge cut
the tool in a free hand method. The tool will be pulled in the
direction of the handle that has the throttle/ control valve. For
that reason we recommend that the tool be plunged slightly
o󰀨 the 12 o’clock mark toward the throttle handle side. This
will help to ensure good visibility of the saw as you complete
the cut, near the 12 o’clock position of the pipe. It is also
should be noted that a line should be made from 10 to 2
O’clock over the top of the pipe. While plunging the tool into
the pipe reference this line with the edge of the cutting guard-
do not line up with the blade. Once the strap is installed you
will not be able to see anything directly in the path of the
blade or under the blade guard. As the cut is completed you will be able to see the reference mark at the
10 o’clock position and can make adjustments to the cut if you have tracked o󰀨 course during the cut.
2. Once the plunge cut has been made and the tools
alignment is satisfactory the strap must be installed. It will
also be time to add any additional reference marks to the
cutting surface to help aid in alignment start/ stop locations,
etc.

PARTS
3. Pull belly saw in the direction of the throttle handle. This will provide the straightest cut. If the tool is
pushed from this handle the saw will track of course even if light pressure is applied. Once you reach
the termination of the cut you can release the strap and remove the saw. If the cut has not completed in
perfect alignment this would be the opportunity to adjust the cut in a freehand method. If the cut does
align perfectly use caution as pressure from ground shifting can cause the pipe to shift without notice and
with tremendous force. The weight of the cut pipe can pull the saw out of an operator’s hands when the
tool is strapped to that pipe. This is why we recommend not completing the cut until the saw is removed/
unstrapped from the pipe and a more visible nish cut is made.
Pipe Size Depth of Cut* Number of Links
8 2.09 2 Long 1 Short
10 1.71 2 Long 1 Short
12 1.48 3 Long 1 Short
14 1.32 3 Long 1 Short
16 1.2 4 Long 1 Short
18 1.11 4 Long 1 Short
20 1.04 4 Long 1 Short
24 0.93 4 Long 1 Short
In certain situations the rollers may interfere
with the saw or on thick types of pipe the saws
strap may contact the pipe. This will hinder a
free moving tool during the cut. In these cases
you may spread the roller trucks apart for better
coverage around the pipe.
