6280 BLADES
• Wood or wood like floors: pound
down or remove any nails
or metal obstruction to avoid blade
damage.
• Blades can be offset in cutting
head for easier access to toe kicks
or removal along the wall (See
Figure A).
• Sheet vinyl, solid vinyl, rubber tile,
urethane or PVC sheet roofing,
will need to be scored for best
removal results. Nationals #584
Scoring Tool (See Figure B).
• Score flooring to the width of the
blade (See Figure C).
• Keep in mind, narrow width blades
will make a cleaner floor surface.
• KEEP BLADES SHARP!
• Dull blades greatly affect the
performance of the machine.
BLADE SETTING
• Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed.
• Proper blade size and placement, depending on material and sub-floor type, affects performance.
• The harder a job comes up, for best results, use a smaller blade.
• Start with a narrow blade, then increase blade size to optimize cutting pass. Narrower blades work
easier than wider blades and usually clean the floor better. Wider is not always better or faster.
• Normally bevel on blade is up for concrete. Bevel down for wood or soft sub-floors.
