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.

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
