Accessory Disk [P]. Place the Wooden Wedge [U]
between to the inside edge of the Tool [GG 1] and
the Accessory Disk [P].
b) Firmly tap the Wooden Wedge [U] into position
using a hammer. Tap the Wooden Wedge [U] until
the Tool [GG 1] is securely fastened into the
Accessory Disk [P]. Rotate the Accessory Disk [P]
and repeat this procedure for all six (6) tools.
⇒
Note: Soaking the Wooden Wedges (U) in water
before assembly could increase the gripping power
of the wedges and prolong the time that the tool
stays fixed to the machine.
c) Gently lower the front of the machine until the tools
touch the ground.
d) Pivot the axle so that it is in the OPERATION
POSITION [F] [FIG. 2].
e) Lower the FRONT SHIELD [A] from its upper
position. Loosen the three (3) CAPSCREWS [B]
and lower the shield so that it is only 3/8-1/2” (10-
12 mm) from the ground.

Grinding Stones [See FIG. 14]
For Light Grinding of Rough Areas. Material is Silicon
Carbide, the “grit” size is designated by number (similar
to most abrasive products). The larger the number, the
finer the grain structure, the smoother the surface finish
achieved, and the longer the grinding stone life. Some
of the available “Grit” Sizes are shown below:
a) TC-10 Coarse Grit: Maximum material
removal, General grinding & removal of
trowel marks, high spots, and rough
sections of concrete. Life 4-10 hours.
b) TC-24 Medium Grit: Lower material
removal rate, Finer finish grinding of
concrete, and rough grinding of Terrazzo
and other stone type. Life 6 – 10 hours.
c) TC-80 Fine Grit: Still lower material
removal rates. For polishing of concrete
and medium grinding on Terrazzo and
stone type floors. Life 8 – 20 hours.
4.2
Diamond Segment Blocks [FIG. 15]
Remove High Spots, Trowel & Rain Marks, Paints,
Sealers & Mastics, Uneven Joints, Aggressive Grinding
of Large Rough Areas, Removal of epoxies, paints and
many thin film coatings, or Final Preparation for new
coating.
Available In Different “Grit” Sizes:
GB-10 General Purpose
GB-20 Abrasive Materials
GB-30 Epoxy & Non-Abrasive Materials.
Removal Rates: Up to five (5) times the material
removal rate of Coarse Grinding Stones.
Life: Up to 15 times the life of Grinding Stones.
4.3
Tungsten Carbide Blocks
[See FIG. 16]
Comes in a complete kit (P/N 177823) [FIG. 17]
that includes six steel blocks, six tungsten carbide
cutters, hardware and tools, and six wooden wedges.
A replacement cutter kit (P/N 177824) [FIG. 18] is
also available. It includes six tungsten carbide cutters,
six wooden wedges, and all hardware and tools to
mount the cutters.
Removes material with a cutting or shaving action
and works best at removal of thick coatings such as
paint buildups. Not recommended for thin (< 5 mil)
films of materials. Not recommended for adhesives,
rubber deposits and mastics that have a tendency to
extrude or smear rather than “shear” loose from the
floor surface. A water or a water / sand mixture can be
added on the surface to reduce this problem
.
Adding
additional external weight to the machine can also
improve the material removal rate.
Each tool contains one tungsten carbide insert.
Each insert has eight (8) cutting edges. When one of
the edges becomes dull, loosen the attaching bolt
using the hex wrench provided, and rotate the insert 90
degrees. When these four (4) cutting edges are dull,
simply remove the insert and flip it over to expose four
(4) new cutting edges.
4.4
Scarifier Wheels [FIG. 27, FIG. 28]
Remove Fiberglass, Ice, Oil-Dry, Foam-Fill Packing
Material & Floor Buildups. Lightly Textures Surface.
Available in three (3) configurations:
a) Star Wheel: Hardened Carbon Steel
material. For removal of thin coatings and
encrusted accumulations of material.
Cleaning concrete of asphalt surfaces.
Removing thick build-up of grease, paint,
and some resins. Light scarifying before
application of coatings or sealer. Creates
a swept, or “broomed” type of finish.
b) Beam Wheel: Medium duty, for concrete
and asphalt scarifying. De-scaling steel
decks. Removing thick material build-up of
grease, paint, and some resins. Twice the
life, near the same cost as a star wheel.
c) Tungsten Carbide Wheel: Heavy Duty
asphalt or concrete scarifying, or de-
scaling of steel decks. 10 times the life of
a star wheel.
Assembly: When new cutters are installed, be sure
to “stagger” the washers in order in avoid any “blind
spots” in the cutter path (On any one cutter block
put the first washer on the opposite end of each
stack of cutters). Also make sure that the wheels
can rotate freely when the attaching Capscrews are
tightened.
Bushings: Be sure to inspect the cutter bushings on
a regular basis. Worn bushing can cause the
