APPLICATION SETUP
VCT Tile
Never use a blade wider than the size of the tile being removed. If goods being removed
still do not come up clean or machine jumps on top of goods, reduce blade size until
proper blade size is found or use a smaller portion of the blade.
Pure Vinyl Rubber Tile
Goods will need to be scored down to 10-12” (25.4-30.5 cm) for proper removal. Self-
scoring blades can be used with some materials. A 10” (25.4 cm) blade is recommended
for this product, but determine what size blade works best.
Direct-Glued Carpet
Can be done with either self-scoring blades or pre-score carpet to blade width prior to
stripping with #584 Scoring Tool. Pre-scored carpet makes machine easier to control and
blades stay sharper longer. Blades up to 16” wide can be used. Normally 12-14” (30.5-
35.5 cm) blades are used on direct-glued carpet, secondary-backed, unitary, double-
glued, vinyl foam, and urethane foam. Latex foams come up easily with a 16” blade.
Concrete
When working on concrete slab, normal blade position is bevel up for best performance,
especially when cleaning adhesive. On occasion, bevel down gives better blade life. Test
each job for best performance.
Gypcrete and Soft-Poured Flooring
Requires blade bevel down to create a better wearing surface.
BLADE SHARPENING
Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed. In use,
blades develop a back-bevel (Figure 6). When re-sharpening, blade will not be truly
sharp until all back-bevel is gone.
Note: Thinner blades are easier to sharpen, but they also break easier.
•
Always wear gloves and safety glasses.
