Types of tear outs
Keep blades sharp! Keep your work area clean and clear of debris.
Always wear personal Protective equipment when working with the machine.
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 the machine jumps on top of goods, reduce blade size to
a smaller blade until proper blade size is found or use a smaller portion of the blade.
Vinyl-, Rubber, PVC, Direct glued carpet
Goods will need to be scored down to 254 to 305 mm for proper removal.
Pre-scored carpet makes the machine easier to control and blades stay sharper longer. Blades up to 685 cm
wide can be used. Normally 305 mm blades are used on direct glued carpet, secondary backed, unitary, double
glued, vinyl foam, urethane foam. Latex foams come up easily with a 685 mm blade.
Self scoring blades can be used with some materials. A 254 mm blade is recommended for this product, but
determine what size blade works best.
Ceramic (glued with double duty or mud sets):
Before removing ceramic tile, tiles will have to be pre-broken with a mallet or large hammer.
On small random block styles of tile, pre-breaking may not be necessary.
Open an area large enough for machine or blade to fit in, or start from a doorway.
Keep work area clean to keep good wheel contact with floor. Use slow speed and small blades.
Blades can be offset in cutting head for easier access to toe kicks or removal along the wall.
Wood and wood like floors
Pound down or remove any nails or metal obstruction to avoid blade damage.
Glued hard wood flooring
A 254 mm blade is recommended for regular adhesive, a 152 mm blade for epoxy.
For proper removal of hardwood flooring (plank solid, plank laminated, parkay, parquetry laminated)flooring
must be scored to blade width.
This is done by using a circular saw set at a depth of 99% of the thickness of the board, just missing the
subfloor surface when on concrete
A chalk line for scoring lines can be used across the floor the width of the blade
True parkay flooring scoring is not necessary. It will come up in small pieces.
When working over plywood sub-flooring, try to run machine in the same direction as the grain in the wood.
Blade in most cases 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 counterweights will help on all soft surfaces.
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.
Gibcrete and soft poured flooring
Usually requires blade bevel down to create a better wearing surface, although bevel up may work if some
weights are removed.
Beware of expansion joints and floor mounted receptacles or other obstacles in the floor.
