1. Index
It is important that all persons operating and maintaining the machine read this manual
carefully and understand it fully. Keep this manual near to the machine, so that it can be
consulted every time.
Only authorized and trained personal may operate the machine.
2. Machine description
The Blastrac blast cleaning machine 1-10DPS75 is a downward blasting machine with a
closed abrasive circuit designed for the pre-treatment of horizontal surfaces. The bouncing
impact of metallic abrasive onto the surface to be treated thoroughly removes surface
contaminants, coats of paint, sealants and thin coatings.
A suitable filter unit must be connected to the machine in order to separate the dust from
the abrasive. A specially designed dust collection system ensures dust-free operation of the
machine and clean air at the workspace.

4. Initial operation
It is committed to inspect the machine before use it.
It is not permitted to use the machine if the machine safety is not according the checkpoints
below.
Checkpoints powersupply
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 them reels.
No damage is permitted for electrical cables.
Use a electrical power supply connection with earth connecting.
The circuit breaker of the power supply must have a ‘’D’’ characteristic. Circuit
breakers with a “C” or “B” characteristic can give problems by switch on the
blastmotor.
Checkpoints of machine
Safety functions and operating functions must work correct.
Check the following parts for damage and wear: blastwheel, feedspout, liners,
magnet- and brush sealing.
No loose bolts and nuts permitted
No any damage of electrical components permitted.
Dust hose must be undamaged and the connection must be reliable.
Check the parts of the separator on wear and defects. Remove foreign bodies and
dust deposits.

5. Operating
To operate the 1-10DPS75 the following instructions are committed
Before switch on
Check if the distance from magnet to the floor is 6 – 8 mm. Check this height with
aluminium strips.
Check the distance from brush sealing to the floor. This may be max. 1 mm.
Fill the separator equally with the selected abrasive up to the bottom of the separator
tray. Magnetic valve must be closed whilst doing this.
Connect the blastmachine and filterunit with the dusthose. This connection must be
reliable.
Connect the power supply cable of the filterunit with the generator. Be sure that
electrical power supply is correct.
Switch on the machine
Before switch on the blastmachine, switch on the filterunit.
Press the green push button “Blastwheel ON”and check the rotating direction of the
blastmotor. The correct direction is given with a arrow on the housing of the motor.
Select the speed using the speed control knob. (item 11 of machine description)
When the machine is traveling pull the abrasive control cable to open the magnetic
valve. Observe the ammeter. It may indicate the full load amperage. After having
blasted aprox. 2 m, close the abrasive valve, stop the machine and check the blasted
surface.
If the ‘hotspot’ is too much on the right, turn clockwise the cage a little bit. Never
adjust the cage during blasting.
Switch off the machine
Close the abrasive valve
Press the red button “Blastwheel OFF”
Switch the main switch to position “OFF”
Pull out the connector of the main power supply of the machine.
Switch off the filter unit.
Wait for standstill of all drives before any inspection or maintenance works are
started.

6. Maintenance
Changing the liners
Loose the press bolt of the top liner and remove the cover.
Loosen the nuts of the side liners and plenum liners. Take them out at the bottom of
the housing.
To mount the liners, keep on the following sequence:
First place the plenum liners and fix them with the nuts.
Place the side liners inside the housing. The sideliners may stick out the body for
max. 1mm. Tighten the nuts.
Place the top liner in the housing and make sure that the top liner sits close to the
edges of the side liners.
Place the cover and tighten the bolts.
Tighten the pressure bolt of the top liner slightly and press the top liner against the
side liners.
Changing the tune-up kit
De tune-up kit consists of the blastwheel, the cage and a bolt.
Remove the feed spout
Remove the cage clamps
Remove the cage and blastwheel cover plate
Block the blastwheel and remove the central fixing bolt
Take the blastwheel out of the housing
Use a new central fixing bolt when mounting a new blastwheel
Place the blastwheel on the hub and tighten the central fixing bolt.
Fix the blastwheel cover plate with 4 nuts
Insert the control cage in the center and clamp the cage with the control clamps so
that the blastwheel can rotate freely
Turn the blastwheel manually. It must rotate freely.
Place the feed spout between the abrasive valve and the cage.
Clean the machine every day with air and non-aggressive materials. Never use a high
pressure water cleaner to clean the machine.
Store the cleaned machine in a dry room. Protect the electrical motor from moisture, heat
dust and shocks. Remove the abrasive out of the abrasive storage hopper.
All repair work has to be done by qualified Blastrac personnel, this guarantee a safe and
reliable machine.
Any guarantee on the machine is expired when:
By not using original Blastrac spare parts and abrasive.

7. Selection of abrasive
Media nr. 2
Is often used when the surface is only subsequently sealed.
−creates fine profiles, e.g. on vacuum concrete and non-glazed tiles
−removes thin layers of rust on steel surfaces
−removes thin layers of paint
Media nr. 3
−creates a fine to medium texture on concrete.
−removes glazing from tiles prior to subsequently coating with antiskid floor sealings
−removes old impregnations and coatings about 1 mm thick
Media nr. 4
Standard abrasive, suitable for about 50-60 % of all applications. Creates a medium profile on
concrete. Fulfils the same purpose as Media No. 3 when a higher speed of the machine is
required, e.g. on asphalt, in order to keep the thermal load low.
−removes laitance from new concrete
−roughening of smooth concrete or natural stone
−removes coatings with a thickness of 1-3 mm
−cleaning of steel surfaces
Media nr. 5
This media is used to create a coarse profile or to increase the work speed in the case of
surfaces hard to treat.
−removes sediments on concrete prior to coating
−removes thick paint coatings or rust from steel surfaces, bridges, tanks, etc.
−removes flexible coatings on parking house decks
−removes road markings and retexturing of asphalt and concrete roads
Media nr. 8
Only as an addition to Media No. 3, No. 4 and No. 5 with maximum 30% content.
Media No. 8 should never be used without blending since otherwise the wear in the machine as
a whole would increase disproportionately.
−removes polyurethane coatings
−removes adhesive remnants
−removes rubber deposits
−penetrates coatings hard to remove
−also suitable to be used on steel for extraordinary roughness
