Components and Assembly

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.
WARNING:
BLADES ARE SHARP, USE EXTREME CAUTION. ALWAYS WEAR
GLOVES AND SAFETY GLASSES WHEN HANDLING BLADES. NEVER CHANGE
CUTTING HEAD OR SERVICE BLADES WHILE MACHINE IS RUNNING.
