  • Page 15: Cutting Head & Blades

    7. Cutting Head & Blades Weight vs. Sharpness The most common way to compensate for a dull blade is to add more weight and raise the blade angle (see re- scrape setting). Weight allows dull blades to be used to a point. Weight also causes blades to dull and break easier.

  • Page 17 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. • If the material isn’t coming up easily, use a smaller blade for best results. •...

  • Page 18: Blade Application

    8. Blade Application A great deal of work can be accomplished in a short amount of time using the scraper. To do this however, the operator must use the correct blade type and correct blade angle. Often when the blade begins to dull, it is tempting to raise the angle of the blade.
  • Page 19 Many different floor conditions exist but the hard and fast rule for scraping is that the tougher the material being removed, the skinnier the blade. The best course of action is to start small and the move to wider blades as per the conditions of the job.
  • Page 20 Dull blades can be sharpening by using electric grinder with disc of 120 grit or finer. Also a tooth hand file can be used. Caution is required during sharpening. For soft materials like carpet, vinyl, and membranes it is possible to use self-scoring blades: Wings It’s important to keep the “wings”...
  • Page 21 Types of Blades Different blades are required for different materials and different sub-straights. Although the choice is situation dependent, below are describe a few examples of common industry practice: Self-scoring blades used to vinyl, carpet tiles, soft to medium PVC, soft cork, linoleum, enhancer and unibond hot melts.
  • Page 22 Thin coating set-up: slide plate with distance from 6” to 8” to the floor or from 1/4” to 1/2” off the wood. Correct distance need to be set after tests. Preferred application is cutting head (8” to 26”) with Razor Blades. But it is possible also to work with cutting head (8” to 14”) with standard blade.

Using as wide of a self- scoring blade as possible, make ditches apart crossways from the way the machine will be removing the materials.
