Cutting Head and 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. Blades of any thickness tend
to catch cracks and expansion joints and will bend or break the blade if set at a high angle. For best results, run a small ditching
blade at a low angle to identify as many cracks and joints as possible. If blades are breaking, you are misunderstanding the
conditions.
Cutting Head Pitch
Set the cutting head angle to where the material comes up the easiest. The lowest is usually the best.
Steep Cutting Head Pitch
The cutting head pitch can be adjusted by simply placing the cutting head axle in 1 of the 4 holes or use the right-hand inner handle
(for dual-lift machines from S.nr.30340 & up). A steep angle is only used for re-scraping. The cutting head has to be raised to the
highest hole. Not raising the cutting head when operating the machine at a steep angle will cause the machine to jump and buck.
It does not give the operator a clear vision of the cutting head and it raises the machine to operate at an unsafe operating height.
Failure to raise the cutting head could cause machine damage and/or bodily injury.
Swivelling Tool Holder
The swivelling tool holder keeps the blade in contact with the floor even when the floor is uneven. When using a flat blade, by
swivelling the head over 180° allows you to use the other sharp edge on the blade without having to replace the blade.
Saving Time with Extra Blades, Blade Holders and Tool Holders

8 | P a g e
The machine is supplied with one tool holder. Having additional tool holders, blade holders and blades will save time on the job.
When the blade is dull, instead of taking the time to replace it or sharpen it on the job, replace it with another prepared set. Or,
when a different type or size of blade is needed, you have them ready to use.
1 Blade –depending on the needs
2 Blade holder –lower part
3 Blade holder –upper part
4 Tool holder
5 Debris deflector –new holder shape
6 Universal lower cutting head support
Blade Choice
Proper blade size and placement, depending on material and sub-floor
type, affects performance.
•Use sharp blades. Dull blades reduce cutting ability.
•The harder the floor to come up, the smaller the
blade needed for best results.
•Start with a narrow blade, then increase the blade
size to find optimum result.
•Narrower blades usually leave a cleaner surface.
•Set blade bevel correctly.

Blades Application
Efficient and fast work can be achieved when you use the correct blades and settings. The operator must remember to prepare
the correct angle and keep the blade sharp. During work the blade will become dull. To reduce this process the operator can add
extra weights to the front or change the angle between the blade and the ground. CAUTION! That action makes blades more
potential to break. Important is to understand that when the blades are breaking, some of the conditions of usage or settings are
not correct. In many cases the angle between tool and ground can’t be too big because the machine can jump and even takeover
to the back.
The work area should be kept clean. When a portion of material is removed on the first run, it is always better to clean the floor
before starting the second run. Debris and dirt can make the blade dull really quick.
Blade Changing
•Use an extended wrench to keep hands away from sharp edges
•Wear cut resistant gloves
•Ensure plug is removed from power supply
•Place a block under the front of the machine
•Loosen the 5 bolts
•Remove existing blade if there is one
•Replace with a sharp blade
•Ensure new blade is far enough into blade holder to be secure
•Retighten bolts
•Only replace blades when machine is stable.

10 | P a g e
Always wear cut-resistant gloves when handling blades.
Using Wing Blades
Use only sharp winged blades.
Types of Blades
For different materials special tools need to be mounted. The shape and width are defined by many years of experience. Below
are a few types described:
Self-Scoring Blades. Used for vinyl, carpet tiles, soft to medium PVC, soft cork, linoleum, enhancer and universal bound
hot melts. With this type of blades scoring is make automatically by the “wings”.
Premium Blades. Designed to work on wood, thin ceramic, tiles, VCT, VAT, re-scraping thin set, glued ceramic,
elastomeric coating, rubber epoxy. After some work period the blades need to be sharpened.
Heavy Duty Blades. Designed for wood, VCT, VAT, thin ceramic, re-scraping, all carpets, elastomeric coatings, cork, rubber
and urethane coatings. They are thicker than premium blades.
Premium Chisels. For use on ceramic, thin set, wood, decorative concrete and mud set.
Heavy Duty Chisel (carbide tips). For use on wood, ceramic, elastomeric coatings and epoxy. These blades have carbide
tips to give them a long lifetime.
Using the correct blades is only half of the success. The second most important thing is to put the tool in the optimal geometry
to the ground. Below you will find information about the most popular materials.
VCT –Tile. Cutting head in the lowest hole. It’s better to start with a narrow cutting head. The best option should be
Heavy Duty Blade.
Foam Back Carpet Set-Up. Cutting head in the lowest hole. It is possible to use a blade from 250 to 350mm but in some
situations a good choice can be using a blade from 350 to 700mm.
Ceramic Set-Up. Cutting head in the lowest hole. Usually Premium or Heavy-Duty chisels will be the best for this job.
Secondary Backing Carpet Set-Up. Cutting head in the lowest hole. Proposed settings are a blade-width from 255 to
685mm with Heavy Duty Blades and Self Scoring Blades.
Double Stick Carpet Set-Up. Cutting head in the lowest hole. In this case it is good to start with a blade-width (255 to
355mm) with Self-Scoring Blades. It is important to have sharp blades.
Wood Set-Up. Cutting head in the lowest hole. Preferred are Premium or Heavy-Duty chisels or a blade width (150 to
205mm) with Heavy Duty Blades. The machine needs to have an angle of 45° to the grain of the wood.
Thin Coating Set-Up. Cutting head in the highest hole for the floor or in the lowest hole for wood. The correct distance
needs to be set after tests. Preferred application is a width (200 to 685mm) with Premium Blades.
Re-Scraping Set-Up. Cutting head in the highest hole. A blade width (200 to 685mm) with Premium Blades can be used.
Good to remember that the blade should be one step bigger than the blade holder.
Working Over Concrete. The most important thing is to install the blade bevel up because this kind of material is hard to
remove. The best way is to test different settings with Heavy Duty Blades.
Working over Soft Sub-Floor. Cutting head in the lowest hole. Preferred are a Heavy Duty Blade or a Premium Blade.
Blades need to be installed with bevel up and the position needs to be as flat as possible.
Working Over Wood. In this case it is important to know if the floor is strong enough to put the machine on it. Otherwise,
it is better to take out the weights. Cutting head in the lowest hole. Preferred are Heavy Duty Blades or Premium Blades.
