1) #0 Prep Tool (leaves a smooth profile)
Description
The #0 Prep Tool (401922) is a metal bond preparation tool that has the EG attachment
system as a standard for use on any GP machine. Its uses are to remove adhesives, thin-
sets, surface inequalities of +/-.16 in (4 mm) and epoxy coatings with thickness of less
than .16 in (4 mm). The #0 Prep Tool is designed to be used as a dry removal tool only.
The #0 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 #0 Prep Tool will be one
that is consistently scratched and resembles 80 grit sand paper. Approximate life of the #0
Prep Tool is 30,000 SF (2,787 M
2
).
Execution
1. Attach the #0 Prep Tools to the GP30 and place it in operating position. Attach appropriate power* and
vacuum dust collection hose to the GP machine.
2. With weights in neutral position** or off machine, start the machine and adjust speed to 45Hz.
3. Upon starting the machine, continuously move machine in side-to-side pattern ensuring that machine
is will grind the floor evenly. 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. 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
#0 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 #0 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 #0 Prep Tool is too aggressive, simply add more weight to the handle to
reduce grinding pressure.
Flooring Condition Qualifications
Use of the #0 Prep Tool requires that the surface to be treated is completely dry. For floors that have
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).
Machinery Qualifications
The #0 Prep Tool is designed to attach to and work perfectly with any GP machine. Quantity of #0 Prep
Tool will vary by model:
• GP30: 12 pieces
