2) #00 PCD Prep Tool (leaves a rough profile)
Description
The #00 Prep Tool is a combination PCD/metal bond preparation tool that has the EG
attachment system as a standard for use on any GP machine. The #00 Prep Tool is
directional. This means that any set of #00 Prep tools will always contain 50% right-hand
tools (401924) and 50% left-hand tools (401923). Its uses are to remove adhesives, thin-
sets, surface inequalities of +/-.16 in (4mm) and epoxy coatings with thickness of less
than .16 in (4 mm). The #00 Prep Tool is designed to be used as a dry removal tool only.
The #00 Prep Tool is made for use on
concrete and should never be chosen to grind terrazzo,
marble, or granite. The concrete profile after using the #00
Prep Tool will be one that is considered rough to the touch
having up to .04 in (1 mm) deep grooves. Approximate life
of the #00 Prep Tool is 30,000SF (2,787 M
2
).
Execution
1. Attach the #00 Prep tools to the machine by placing
the right-hand tools (#00R) in the tool holders that are
turning clockwise and the left-hand tools (#00L) in the
tool holders that are turning counter-clockwise.
2. Place the machine in the operating position. Attach
appropriate power* and dust collection hose to the machine.
3. With weights in neutral position** or off machine, start the machine and adjust speed to 40Hz.
4. Upon starting the machine, continuously move machine in side-to-side pattern ensuring that machine
is continuously moved while running. If for any reason the machine cannot be continuously moved,
i.e. cord management, adjacent work, obstacles, etc., stop the machine until it can be operated as
specified above.
5. Upon satisfactory completion of surface prep, remove machine and use a dust collector to clean the
surface.
* Power source voltage will vary by machine being used and should be verified for compatibility before
connecting machine to it. Dust collection by appropriate dust collector is compulsory as harmful and
damaging dust will be produced if dust collection is not used or is of inadequate capacity. The life of the
#00 Prep Tool will also be significantly reduced if vacuum is not of appropriate capacity.
** The GP machines all have pocket weights for the purpose of varying the grinding pressure of the
machine. It is suggested to begin with the #00 Prep Tool with no added weight to gauge performance.
If the tool is not aggressive enough, simply add more weight to the grinding head of the machine to
increase grinding pressure. If #00 Prep Tool is too aggressive, simply add more weight to the handle to
reduce grinding pressure.
Flooring Condition Qualifications
Use of the #00 Prep Tool requires that the surface to be treated is completely dry. For floors that have
excessive adhesives or built-up contaminants, a scraping of the floor will improve performance, but is
not required. As a general rule, it is best to inspect floor BEFORE beginning to note or mark obstacles
such as floor drains, protrusions from floor, and elevation changes in excess of .16 in (4 mm).
