MK-VTS/50 FLOOR SCRAPER TYPES OF TEAROUTS
BEVEL UP
CONCRETE FLOORS
BEVEL DOWN
WOOD FLOORS
SUBFLOOR SURFACES
• WOOD: When working over plywood sub-flooring, try to run machine in the same direction as the
grain in the wood. Blade in most cases should be bevel down. On solid wood floors, like plank, run
in the same direction as the plank, not cross grain or cross plank. Removing the
front counter weight will help on all soft surfaces.
• CONCRETE: When working on a 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.
• GIBCRETE AND SOFT POURED FLOORING: Usually requires blade bevel down to create a
better wearing surface, although bevel up may work if front counter weight is removed.
Beware of expansion joints and floor mounted receptacles or other obstacles
in the floor.
CAUTION
• GLUED HARD WOOD FLOORING: A 10" blade is recommended for regular adhesive, a 6" - 7"
blade for epoxy. For proper removal of hardwood flooring (parkay laminated, plank laminated,
plank solid) flooring must be scored to blade width. A ripping guide attached to the saw can be
used to eliminate chalk line marks. Open an area large enough to fit machine or start from a
doorway. It is important to keep all debris cleaned up for maximum performance of machine. True
Parkay flooring scoring is not necessary. It will come up in small pieces.
Never remove flooring containing asbestos without
fully understanding proper state and federal proce-
dures and guidelines for removal of these products.
Laws are different from state to state.
WARNING
(A)
Scoring is done by using a circular saw
set at a depth of 99% of the thickness of
the board, just missing the subfloor sur-
face when on concrete. A chalk line for
scoring lines can be used across the
floor the width of the blade.
Normally the bevel on the blade is up for concrete; bevel down for wood or soft sub-floors. NOTE:
