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
4.1Grinding Stones [See FIG. 14]
For Light Grinding of Rough Areas. Material is Silicon Carbide, the “grit” size is designated by number (simi- lar 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)
b)
c)
4.2Diamond 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:
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.
4.3Tungsten 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.
4.4Scarifier Wheels [FIG. 27, FIG. 28]
Remove Fiberglass, Ice,
Available in three (3) configurations:
a)Star Wheel: Hardened Carbon Steel material. For removal of thin coatings and encrusted accumulations of mate- rial. Cleaning concrete of asphalt surfaces. Removing thick
b)Beam Wheel: Medium duty, for concrete and asphalt scarifying.
c)Tungsten Carbide Wheel: Heavy Duty asphalt or concrete scarifying, or
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 Scarifier Wheels to break and be thrown against the inside of the machine frame.
