save time on the job. Insert blades into the extra cutting heads before starting a job.
When the blade is dull, take out the cutting head and replace it with another.
Shear Point
The shear point is the point where material to be removed will cut cleanly from the floor. If
the blade is too wide, too dull, or too steep the shear point is lost.
Inserting the Cutting Head
1.
With machine off, insert desired cutting head into cutting head holder.
2.
Secure with cutting head clip.
Swivel Head
The swivel head keeps the blade in contact with the floor even when the floor is uneven.
When using a flat blade, turning the head over 180° provides another sharp edge on the
blade without having to replace the blade.
Inserting or Changing Blades
Sharp blades are imperative for good performance.
1.
Using a 3/4’’ socket wrench, loosen bolts on cutting head. Quantity of bolts will vary
depending upon cutting head size.
2.
Insert blade into the cutting head to back of notch (Figure 7); tighten firmly.
Note:
A cordless 3/8’’ drive impact wrench will speed up this process.
Inserting a Shank Blade
Shank blades do not require a cutting head.
1.
Insert desired shank blade into cutting head holder.
2.
Secure with cutting head clip.
Self-Scoring Blades
Instead of pre-scoring a job for soft goods (e.g. carpet, vinyl, linoleum, membrane), the
self-scoring blades automatically do the scoring. It is important to keep the “wings” on a
self-scoring blade sharp.
