CUTTING HEAD & BLADES

SHANK BLADE INSERTION

Shank blades do not require a cutting head. Insert desired shank blade into cutting head holder. Secure
with cutting head clip.

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 and shoe blades for soft sub-floors.
• KEEP BLADES SHARP.
• Dull blades greatly affect the performance of the machine and reduce cutting ability, resharpen or
replace as needed.
• Keep your work area clean and clear of debris.
• After you have removed a portion of material, remove it out of the way. This will give the machine
maximum performance and help to keep the work area safe.
• Always wear gloves when handling blades.
• Everyone in work area should wear eye protection.

SELF-SCORING BLADES

Instead of pre-scoring a job, for soft goods (carpet, vinyl, linoleum, membrane) the self-scoring blades
automatically do the scoring.

BLADE INSERTION OR BLADE CHANGING

Using a 3/4'' socket wrench, loosen bolts on cutting head. Quantity of bolts will very depending upon
cutting head size. Insert blade into the cutting head to back of notch (See Figure A). Tighten firmly.
Note: A cordless 3/8'' drive impact wrench will speed up this process especially out on the job.
• Sharp blades are imperative for good performance. • Always wear gloves when handling blades.
