2. Machine description
The Blastrac scarifier BMP-215 can be supplied with a 110V, 230V or 400 volt electric motor or with a
combustion engine. The intended use of this scarifier is to roughen up existing horizontal surfaces and
removing coatings. It can be used on almost any surface (concrete, asphalt, stone and steel). The machine
may not be used for other purposes. The manufacturer will not be liable for damage resulting from incorrect
usage, in these cases the user assumes all risks.
The drum of the scarifiers revolves at +/- 1700 revolutions per minute. (RPM)
The depth of scarifying can be adjusted by the fine adjustment control on the handle of the machine; by this
means it is possible to treat the surface with light or heavy cuts as is required.
The machine may not be used without an adequate dust extraction system. A specially designed Blastrac dust
collection system ensures dust-free operation of the machine and clean air at the workspace.
Application
The scarifier is a very versatile machine and with the appropriate cutters it may be used for the following
applications.
To roughen concrete
To clean most horizontal surfaces
To remove coatings
To corrugate concrete surfaces
To remove road markings
To make non-slip surfaces
The force of impact of a cutter is controlled by the depth
adjustment. With the right depth adjustment, the best performance
is obtained to give the desired result.
With a suitable Blastrac dust collector work can be carried out
without causing excessive dust in the work area, this raises the life
span of the machine and protects the health of the personnel.

It is not permitted to use the machine if the machine safety is not according the checkpoints below.
4.1 Checkpoints electrical power supply
Use only extension cables for extending the main cable that are sized and marked in accordance with
the overall power consumption of the machine.
Electrical cables must be fully unwind of their reels.
No damage is permitted for electrical cables.
Use an electrical power supply connection with earth connecting.
Make sure the power supply is in accordance with the machine specifications.
The circuit breaker of the power supply must have a ‘’D’’ characteristic. Circuit breakers with a “C” or
“B” characteristic can give problems when switching the machine on.
If the machine is to be operated using power from a generator, the generator must be operated in
accordance with the current legal regulations and directives in force. (this applies to the protective
earth conductor in particular) in order to ensure that all safety devices are functioning and to eliminate
possible damage to electrical components.
4.2 Checkpoints of the petrol engine
Make sure there is enough petrol in the engine.
Make sure there is enough oil in the engine.
Check the engine for leakages of oil or petrol.
4.3 Checkpoints of machine
Safety functions and operating functions must work correct.
Check all screws and other fasteners for tightness. No loose bolts and/or nuts are permitted.
Check the electrical components, cables and connections for wear and/or damages.
Dust hose connections must be reliable: use hose clamps and industrial tape.
Dust hose must be undamaged and free of obstructions.
Make sure the drum is in good condition.
Make sure the drum is assembled as shown in the service manual.
Check, when using non symmetric cutters, if the direction of turning is like the figure below.
The tools must hit the floor by centripetal force and not because the axle pushes the tool
(see drawing below).

12
4.4 Manual moving of the machine
To move the machine manually make sure the quick lift lever is in position 1
(see picture) Squeeze in the handles of the quick lift lever and pull it
towards you until it clicks into place. The drum is now free from the surface.
Release the brake from the left wheel with your foot and the machine can
now be pushed around on its wheels.
The machine should only be moved around when the dust hose, and power
supply cable are disconnected.
WARNING! Always make sure all rotating parts have come to a complete
standstill before moving around the machine.
Be careful! Make sure nobodies feet get under the wheels. Wear appropriate
safety shoes when you drive the machine to or from the work area.
Make sure that no vehicles, such as forklift trucks and other equipment run over the electric cable and the dust
hose.
4.5 Removing the drum
Make sure all moving parts of the machine have come to a
complete standstill before changing the drum.
Warning!
Always wear Personal Protective Equipment!
The dust can be hazardous to the health!
Wear a dust mask! Wear protective gloves!
1. Loosen the 2 bolts of the side plate.
2. Remove the side plate.
3. Pull the drum from the axle, and support the drum.
4.6 Mounting the drum
Clean the hexagon axle inside the machine and lubricate it over the whole length.
Slide the drum over the axle until it will not go any further.
Mount the side plate. A side plate which is incorrectly mounted or mounted with force, will shorten the
lifetime of the drum bearings.
Never use the machine without a side plate or with an incorrect mounted side plate!

13
4.7 The scarifying drum
The heart of the scarifier is the scarifying drum. The assembly of the scarifying drum is very easy.
Each tool will be pushed on the axle together with spacers according to the enclosed assembly plans (Service
manual). The spacers ensure the necessary distance between the flails or cutters. The enclosed assembly
plans take into account the required lateral clearance of the flails or cutters, approximately 3 - 5 mm.
4.8 The scarifying flails and cutters
Through the use of a few different flails or cutters, and with a few
alterations, it is possible to adjust the Blastrac scarifier for the applications
or rather for the requirements of the specific surfaces. All the machines
work according to the principle of a loose tool seated on an axle. The
rotation of the scarifying drum generates a centrifugal force on the flails or
cutters which are kept by the lateral axles. The flails will be thrown
outwards as far as the clearance between flail and axle allow it. When
striking the surface, particles will be taken off of the surface and the flail
will rebound in the max inner position. So to avoid significant wear on the
axles as well as on the drum, it is required that the flails still have enough
clearance on the axle when striking the surface.

4.9 Control devices
1. Lifting point
Used for lifting the machine with a crane or lift.
2. Control box
The control box has a connection for electrical power, a green start-button and a red stop-button.
Pressing the green start-button will start the electrical motor, and the drum will start rotating.
Pressing the red stop-button cuts off the power to the motor, and the drum will stop rotating.
3. Quick lift lever
In the upright position the drum is lifted off of the ground, in the downwards position, the drum is put
on the ground. The quick lift lever enables the operator to lift the complete drum without changing the
fine adjustment of the working depth, or for easy transport. The lever must be in the upright position
before start-up, in order to prevent a run out of the motor under full load.
Squeeze in the handles of the quick lift lever and pull or push it in the desired position until it clicks
into place.
4. Dust hose connection
The dust hose to the dust collector must be connected here. Use hose clamps and industrial tape for a
reliable connection.
5. Fine adjustment
The working depth can be adjusted by turning the fine adjustment wheel. The scarifying depth must be
adjusted considering the surface to be treated. The flails or cutters must be unhindered thrown up
through the centrifugal force and they must turn free over the lateral axle. When the depth adjustment
is correctly selected, the scarifier will run quiet and constant. Oval worn flails or cutters as well as
broken drum axles indicate a too "high" scarifying depth adjustment.
6. Brake
The brake is foot operated. Use your left foot to click it on or off the left wheel.

5. Operating
During operating the BMP-215, the following additional safety instructions must be followed closely.
Before switching on the machine make sure that no-one can be endangered when the machine starts up.
5.1 Before starting up
Make sure that the drum doesn’t hit the ground. The quick lift lever must be in upper position and the
fine adjustment must be turned up.
Connect the scarifier and the dust collector with the dust hose. Make sure there is a good and airtight
connection, use hose clamps and industrial tape.
Connect the scarifier and the dust collector with the power supply. Make sure the right connection is
available for the machines. (only BMP-215E)
5.2 Procedure to start work
Turn on the dust collector.
Start the machine by pushing the green start-button (BMP-215E) or by
pulling the start cord of the petrol motor. (BMP-215B)
The throttle lever of the petrol engine is fixed to run at the correct RPM.
Check if the drum turns the right direction. (Only BMP-215E)
Slowly let down the quick lift lever.
Turn the fine adjustment clockwise until the desired scarifying depth is
reached.
5.3 Operating during scarifying
During scarifying there has to be a light pressure on the steering handle. This will ensure maximum grip on the
back wheels. Do not pull on the steering handle because this will cause the rear wheels to skid, and also
increases the change of operator fatigue.
Pull the brake handle only when the machine progress is obstructed, by for example sandy subsoil.
Carry out work in parallel tracks in such a way that the dust hose and electric cable do not become twisted.
The next figure shows the recommended working paths leading away from the dust collector.

Scarifying / milling
machine
All persons in the proximity of the machine must wear safety glasses with lateral
protection as well as safety shoes and ear protection. The operator is obliged to wear
close-fitting protective clothing and a dust mask.

16
Make sure that no vehicles, such as forklift trucks and other equipment run over the electric cable and the dust
hose.
The selection of the correct advancing speed of the machine is important for a good result. In the case that the
surface has different characteristics (e.g. different hardness or different coating thicknesses), a uniform result
can be achieved by varying the advancing speed during scarifying / milling.
The advancing speed depends on the material of the surface to be treated and the desired profiling.
The correct advancing speed can be found out by observing the treated surface and varying the speed during
the scarifying / milling process.
Slight profiling on concrete requires a higher speed than coarse profiling.
5.4 Switch off the machine
Pull the quick lift lever up and turn the fine adjustment till the drum does not hit the ground anymore.
Push the red button (BMP-215E) or switch the On-Off button at the front of the petrol motor to Off.
(BMP-215B)
Switch off the dust collector.
Disconnect the power supply.
Pay attention that all twisting and turning machine parts have reached a standstill before inspection or
maintenance duties are carried out.

Provide adequate ventilation when working in a confided space.
Secure the maintenance area if necessary.
Prevent premature wear by keeping the machine as dust free as possible. Clean the machine for this
reason regularly with a dust collector
Clean the machine every day with air and non-aggressive materials. Never use a high pressure water cleaner
to clean the machine.
6.1 The scarifying drum
The scarifying drum is a very important component of your scarifier, so you should pay special attention while
maintaining and repairing.
The main shaft has to be cleaned and lubricated when you replace the scarifying drum, so that any rust or
sediment can’t complicate your work when you change the drum the next time.
If the scarifier drum should be disassembled in order to rearrange it in a different way or to replace wear
parts, it is absolute necessary to observe the quantity and quality of flails / cutters and spacers as described in
the assembly plans shown in the service manual. Also, pay attention that the bores on the cover plate for the
lateral axle are not worn out and all screws are tightened. In order to obtain a uniform and perfect scarifying
pattern on the surface , you need to adjust the correct scarifying working depth, check the correct assembly of
the scarifying drum as well as the appropriate selection of tools for the surface to be treated.
If the scarifying drum is not uniformly assembled the machine will become unbalanced and excessive wear,
will arise. Blastrac will not feel responsible for any faulty parts, that are damaged caused by inappropriate
assembly.
6.2 Belt drive
The tension of the synchronous belt will be carried out through the
motor plate. the motor can be lifted and let down with the 4 hexagon
nuts, which are located above and under the motor plate. The
synchronous belt will be stretched and loosened by lifting and letting
down the motor.
Pay attention that the synchronous belt lies parallel and has the
correct tension. The belt has the correct tension If you could
press it in for approx. 5mm.

IMPORTANT NOTES:
Noise and vibration measurements were taken during heavy operation on concrete. The noise and vibration
levels depend on the working depth, which is in turn determined by the unevenness of the surface. The impact
force of the tools onto the surface is the biggest factor in both noise and vibration levels.
The indicated values are measured on new machines. Noise and vibration levels will vary in different
circumstances. Area influences like open outside or closed inside space, ambient temperature, different
surfaces to be treated, daily use, different tools or accessories, poor maintenance, 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 represent the main applications of the machine. The values
may be measurements from a representative sample of technically comparable machinery. The values may be
used for a preliminary assessment of exposure.
A precise estimation of the level of exposure to vibration and noise should also take in account the times when
the machine is switched off or even running, but not actually in use. This may significantly decrease the
exposure level over the total working period.
