NOTICE
Any operation involving work on pipe containing liquids or gases
under pressure is potentially hazardous. To ensure a safe working
environment, always follow proper procedures including those
available from the equipment manufacturer and your company.
No person is authorized to make plastic pipe joints for natural gas service
unless that person has been qualied through training, assembling,
fusing and testing specimens in accordance with 49 CFR 192.285.
It is the responsibility of the operator to establish a method to
determine that each person making joints in pipelines in their system
is qualied to make those joints.
This manual does not serve to replace but should be used as a
supplement to hands-on training. This manual is not intended to be
used for system design purposes and does not take the place of the
advice of a professional engineer.

INTRODUCTION
This manual contains the necessary information and instructions for
properly using the MTD PolyPeel. Our unique design works on both
pope and the outlets of tapping tees, removing a maximum of 8% wall
thickness. This is very important because removing too much of the
pipe wall during scraping can result in a failed EF fusion. The design of
this peeler will remove the oxidized lm formed on the outside of the
pipe during the manufacturing process.
When utilizing this tool with coiled pipe, ensure that pipe has less than
10% ovality.
FIELD APPLICATION
Step 1
Mark the stab depth of the tting prior to inserting MTD PolyPeel into
pipe as directed in picture.

5
Step 2
Press down on thumb grip and lock arm open by placing arm retainer
pin into slot in thumb grip.
Step 3
Secure mandrel into outlet of tapping tee/pipe to be scraped by rotating
in a clockwise motion via knurled grip on mandrel.

6
Step 4
Once mandrel is secure, rotate MTD PolyPeel body counter-clockwise to
position blade directly over end of outlet/pipe to be scraped.
Unlock blade arm by pressing down on the thumb grip and setting
retaining pin into cutout. Allow blade to rest on surface of outlet/pipe.
Step 5
Rotate MTD PolyPeel body clockwise to begin the peeling process.
Peeler blade will move toward stab depth marking.
NOTE: Rotate peeler with a consistent and controlled speed.

7
Peeling is complete when stab depth marking is removed as shown in
picture above.
Step 6
After peeling is complete, press down on thumb grip and unlock arm
as in Step 2. Remove mandrel from outlet/pipe by rotating mandrel
counter-clockwise, opposite of Step 3.

BLADE MAINTENANCE
AND REPLACEMENT
If at any time the peeler displays signs of skipping or uneven removal of
material from the pipe, remove the machine screw from the blade arm.
Then remove the blade and rotate it to the opposing side, re-install the
blade and machine screw into the blade arm. Test the peeler to ensure
proper removal of pipe material. Once all four faces of the blade have
been worn, contact ISCO for a replacement blade.
