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.
Blade Setting
•
Proper blade size and placement, depending on material and sub-floor type, af
-
fects performance.
•
For better results during difficult removal applications use a smaller blade.
• Start with a narrow blade, then increase blade size to optimize cutting pass. Nar-
rower 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 (Figure 9); bevel down for wood (Figure
9.1)
• Dull blades greatly affect the performance of the machine and reduce cutting ability,
sharpen or replace as needed.
• After removing a portion of material, clear the work area of debris. This will give the
machine maximum performance and help to keep the work area safe.
FOOT PEGS
Rest feet on foot pegs while operating machine. Foot pegs are adjustable. Ensure secur-
ing knob is tightened.
STORAGE
When the machine is in storage, disconnect the blue plug (Figure 10) and turn circuit
breaker to “OFF” (Figure 11).
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.
