Blade application
Do not use a blade wider than the dimension of the tile being removed. If the tiles do
not come up clean or the machine jumps on top of the tiles, install a smaller blade
until proper blade size is found or use a smaller portion of the blade.
The carpet must be scored down (ditching) with a 152mm Self-Scoring blade for
correct removal. Pre-scored carpet (ditched) or pre-cut carpet makes the machine
easier to control and blades stay sharp longer. Normally 254 mm blades are used
on direct glued carpet, secondary backed, unitary, double glued, vinyl foam, ure-
thane foam. Latex foams are easy to remove with a 305 mm blade.
The ceramic tiles will have to be pre-broken with a mallet or large hammer before
removing them with the floorscraper. Use a large hammer to break away enough
tiles to create space for the machine or blade to fit in. Or start from a doorway. Use
slow speed and small blades or chisel. Keep work area clean to keep good wheel
contact with floor.
Pre-saw the wood with a circular saw. Pound down or remove any nails or metal
obstruction to avoid blade damage.
For correct removal of hardwood flooring (plank solid, plank laminated, parkay,
parquetry laminated), the flooring must be pre-sawed. 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. Draw chalk lines across the floor and pre-saw to blade width.
(every 152mm).
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.
When working on concrete slab, normal blade position is bevel up for best perform-
ance, especially when cleaning adhesive. On occasion, bevel down gives better
blade life.
