5.3 Narrow mode steering handle

To work as close as possible alongside the wall, loosen the knob and move the handle to the right.

12

5.4 Blades

Blade choice

Proper blade size and placement, depending on the material and sub-floor type, affects the performance.

- KEEP BLADES SHARP. Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed.

- The harder a job comes up, for best results, use a smaller blade.

- Start with a narrow blade, then increase the blade size to optimize the cutting pass.

- Narrower blades work easier than wider blades, wider is not always better or faster.

- Narrower blades usually clean the floor better.

- Normally the bevel on the blade is up for concrete. Bevel down for wood or soft sub-floors.

• Keep your work area clean and clear of debris.

• After you have removed a portion of material, remove it out of the way.

This will give the machine maximum performance and helps to keep the work area safe.

•

Always wear cut-resistant gloves when handling blades.

• Everyone in the work area should wear eye protection.

13

Wings

It’s important to keep the “wings” sharp. They can be sharpened in the same way like the other blades.

Efficient and fast work can be reached by using correct blades and settings. During work the blade will become dull. When the blade is dull it is necessary to sharpen or replace it.

Having a second cutting head will be helpful, and it

will save you important time and money.

When the machine is running on the second set of tools, the first set can be serviced.

Different parameters of coat or material will require the use of different blades. For example a small blade is perfect for the hard job. But when the material is soft you can use wide blade. The best solution is to start with a narrow blade and during work change it to a wider one if this is possible.

Working place should be kept clean. When some part 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.

Always wear protective, cut-resistant gloves before handling the blades!

Sharp blades can cause serious injury!

Blade changing

Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed.

- Always wear protecting cut-resistant gloves when changing the blades.

- Use an extended wrench to keep hands safely away from the edge of the blade.

- Make sure the main plug is pulled out of the power source before changing the blades.

14

Place a block (1) under the front of the machine, or lay the machine all the way

back on the steering handle.

Loosen the five hexagon head bolts and replace the blade.

It is not necessary to remove the bolts.

Be sure that the blade is far enough under the blade holder, to insure a secure hold.

Never leave the machine unsecured on jobsites.

Only change the blades if the machine is stable!

When it is resting on a block (picture 1) or when the machine lays on a flat horizontal and levelled surface, as shown in picture 2.

Never change the blades when the machine is unstable, machine could fall back down, as shown in picture 3.

2

Blade sharpening

Always wear protecting, cut-resistant gloves and safety glasses.

It is not necessary to remove the bolts. Sharpen the blade mounted to the machine. Using a hand grinder, block up the front of the machine so the blade is off the floor. Sharpen the blade with a 10 cm diameter disk with 120 or finer grit.

WARNING! Be careful, make sure the disc does not catch the edge or corner of blade.

Blade bevel up Blade bevel down

Furthermore there is the opportunity to remove the blade from the machine and to sharpen the blade at a vice, obeying the same way as shown in figures above.

15

5.5 Start up machine

 Before start-up the operating personnel must be familiar with the safety regulations given in this manual.

 Before switching on the machine make sure that no-one can be endangered when the machine starts up.

 Persons who are not operating the machine must not be permitted to stay in the surrounding area of at least 5 meter from the machine.

1. Selection switch must be on ‘0’ position

2. Turn speed control to slowest position.

3. Plug in the main plug.

4. Turn the selection switch to ‘2’ position.

5. Engage forward or reverse switch.

6. Increase speed control to desired speed.

The frequency drive has been factory set, do not change any setting of the frequency drive.

Do not lock the levers for wheel drive into a permanent position. If the operator would lose control or be disabled, the machine continues to operate.

WARNING!

If there is a power failure or the machine stops for any reason, always put the selection switch back to ‘0’!

NEVER leave the machine when the selection switch is in position ‘1’ or ‘2’! When the power failure is rectified and the machine is still in position ‘2’, the machine will start vibrating automatically!

NOTE! When you engage the machine in reverse, the machine will travel with the highest speed.

16

5.6 Types of tear outs

Keep blades sharp! Keep your work area clean and clear of debris.

Always wear personal Protective equipment when working with the machine.

VCT - Tile

Never use a blade wider than the size of the tile being removed.

If goods being removed still do not come up clean or the machine jumps on top of goods, reduce blade size to a smaller blade until proper blade size is found or use a smaller portion of the blade.

Vinyl-, Rubber, PVC, Direct glued carpet

Goods will need to be scored down to 254 to 305 mm for proper removal.

Pre-scored carpet makes the machine easier to control and blades stay sharper longer. Blades up to 685 cm wide can be used. Normally 305 mm blades are used on direct glued carpet, secondary backed, unitary, double glued, vinyl foam, urethane foam. Latex foams come up easily with a 685 mm blade.

Self scoring blades can be used with some materials. A 254 mm blade is recommended for this product, but determine what size blade works best.

Ceramic (glued with double duty or mud sets):

Before removing ceramic tile, tiles will have to be pre-broken with a mallet or large hammer.

On small random block styles of tile, pre-breaking may not be necessary.

Open an area large enough for machine or blade to fit in, or start from a doorway.

Keep work area clean to keep good wheel contact with floor. Use slow speed and small blades.

Blades can be offset in cutting head for easier access to toe kicks or removal along the wall.

Wood and wood like floors

Pound down or remove any nails or metal obstruction to avoid blade damage.

Glued hard wood flooring

A 254 mm blade is recommended for regular adhesive, a 152 mm blade for epoxy.

For proper removal of hardwood flooring (plank solid, plank laminated, parkay, parquetry laminated)flooring must be scored to blade width.

This is done by using a circular saw set at a depth of 99% of the thickness of the board, just missing the subfloor surface when on concrete

A chalk line for scoring lines can be used across the floor the width of the blade

True parkay flooring scoring is not necessary. It will come up in small pieces.

When working over plywood sub-flooring, try to run machine in the same direction as the grain in the wood.

Blade in most cases bevel down. On solid wood floors like plank, run in the same direction as the plank, not cross grain or cross plank. Removing the front counterweights will help on all soft surfaces.

Concrete

When working on concrete slab, normal blade position is bevel up for best performance, especially when cleaning adhesive. On occasion, bevel down gives better blade life.

Gibcrete and soft poured flooring

Usually requires blade bevel down to create a better wearing surface, although bevel up may work if some weights are removed.

Beware of expansion joints and floor mounted receptacles or other obstacles in the floor.

17

5.7 Ditching

Cross room ditching

When removing hard to remove ceramic, Vct or vat, cross-room ditching will help to make the removal easier.

Using a blade 50 to 155mm in width, make ditches 300 to

600mm apart in the same direction as the machine will be removing the goods.

This “relieves” the pressure holding the tiles together.

If ditching helps and the goods are coming up easy, try using a wider blade to ditch with.

Ditch 50

To 155mm

Tile 300

To 600mm

Run the machine in the same direction as the ditches are made

Checker board ditching

To make carpet removal and debris cleanup easier, checker board ditching is very helpful. Using as wide of a self-scoring blade as possible, make ditches apart crossways from the way the machine will be removing the goods. Running the machine crossways from the ditches will make smaller pieces of debris to be hauled away.

Instead of large gummy rolls of carpet, there are small squares that can be rolled, palletized, put on a dolly or folded with the sticky side in. This makes removing the debris faster, easier and reduces the amount of debris.

Ditch should be wide

As much is possible

Carpet width from

1200 to 1800mm

For more information or questions,

contact our experts

at Blastrac for the correct application of the different tools. www.Blastrac.eu

18

Run the machine crossways from the directions that the ditches are made

5.8 Removing weights

To remove weights, release the handles and move the handle 90º forwards .

Warning! The weights are heavy, ask a co-worker for assistance.

The A-weighted emission sound pressure level at the operating position is relative to 20μPa.

The declaration of noise emission is in conformance with EN-ISO 4781.

The measurements and calculations are executed in full conformance with EN-ISO 11202:2010 and EN-ISO 3437:2010.

There is no machine specific noise test code available.

Although the sound pressure level at the operators position does not exceed 80 dB(A), ear protection is still strongly recommended when working with this machine.

(Without the use vibration dampening measures.)

Because the value is above 2,5 m/s², we recommend to take measures to decrease hand-arm vibrations.

Tips for decreasing the exposure to hand- arm vibrations:

-Protect the hands with vibration dampening gloves

E12000 – Anti-vibration gloves

-Switch off the vibrating motor when driving backwards

-Use only sharp blades

-Proper maintenance of the machine

-Scheduled replacement of the shock absorbing machine parts

-Keep the hands warm

-Prepare a work schedule and plan in rest periods

IMPORTANT NOTES:

The indicated values are measured on new machines. Sound and vibration levels will vary in different circumstances. Area influences like open outside or closed inside space, ambient temperature, the surface to be treated, etc. will give different values at all time and could increase the exposure level over the total working period.

The declared vibration and noise emission levels represents the main applications of the machine. However if the machine is used with different accessories or poor maintenance, the vibration and noise emissions may differ. The values may be used for a preliminary assessment of exposure.

For a precise estimate of the vibration and sound load, the times should also be considered during which the machine is switched off or even running, but not actually in use. This may significantly decrease the exposure level of the operator over the total working period.

Identify additional safety measures to protect the operator from the effects of vibration and noise such as: proper and regular maintenance of the machine and the accessories, keeping the hands warm, provision of proper hearing protection and organization of work patterns for example by using rotation schedules.

Old equipment contains valuable materials which are valuable for re-processing.

The machine parts must not be thrown away in the normal household waste,

but should be disposed of at a suitable proper collection system, e. g. via your communal disposal location. This way the materials can be re-used in an environmentally responsible manner.

Despite the fact that this guide is made with care, Blastrac takes no liability for errors in the manual and the possible consequences. We are naturally very interested in your findings and additions.
