1. Introduction
It is important that all persons who are working with or maintaining this machine must
read the manual carefully and understand it fully. Keep this manual near to the machine,
to enable it be referred to at any time
Only authorized and trained personnel may operate this machine.
2. Machine description
The Blastrac blast cleaning machine 500HSH 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
Before using the machine it is of great importance to inspect the machine.
It is not permitted to use the machine if the machine safety is not according the
checkpoints below.
Checkpoints power supply
Use the hydraulic hoses delivered by Blastrac BV.
Hydraulic hoses must be fully unwind of them winches.
No damage is permitted for hydraulic hoses.
Check if all hydraulic couplings are good connected.
Check if all hydraulic coupling are free of leakage.
Checkpoints of machine
Safety functions and operating functions must work correct.
Check the following parts for damage and wear: blast wheel blades, impeller,
cage, liners and brush sealing.
No loose bolts and nuts permitted
No any damage of hydraulic components permitted.
Dust hose must be undamaged and the connection must be reliable.
Check de parts of the separator on wear and defects. Remove foreign bodies and
dust deposits.

5. Operating
During operating the 500HSH, the following additional safety instructions must be
followed closely.
Before switch on
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. The abrasive valve must be closed whilst doing this.
Connect the blast machine and filter unit with the dust hose. This connection must
be reliable.
Connect the hydraulic power supply hoses of the filter unit and blast machine with
the power pack. Be sure that hydraulic couplings are connected according to the
labels on the hoses.
Switch on the machine
Switch unit the power pack (see manual of the power pack)
Before switch on the blast machine, switch on the filter unit.
Select the speed using the speed control knob. (item 5 of machine description)
Switch on the blast motor (item 8 of machine description)
Switch on the fan motor (item 9 of machine description)
When the machine is traveling pull the abrasive control handle to open the
abrasive valve. Observe the manometer. It may indicate the max pressure. 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
Stop the drive motors
Turn off the blast wheel motor
Turn off the fan motor
Switch off the filter unit.
Switch off the power pack
After switch off the power pack the hydraulic hoses are still under high pressure. It
is important to switch on the filter unit or blast motor. The filter unit or blast
machine will work for seconds. This will bring down the hydraulic pressure in the
hoses to zero.
Disconnect the hydraulic hoses of the blast machine and filter unit.
Wait for standstill of all drives before any inspection or maintenance works are
started.

6. Maintenance
Changing the liners
Loose the bolts of the top liner cover and remove the cover and top liner.
Loosen the nuts of the side liners liners. Take them out of the housing.
To mount the liners, keep on the following sequence:
Replace all worn items.
Clean the liners and the inside of the blast housing thoroughly.
Re-assemble the machine in reverse order, using kit between the top liner and the
side liners, and between the top liner and the front and rear plates of the blast
housing.
Make sure that the top liner sits close at the edges of the side liners.
Changing the blast wheel blades and impeller
Remove the abrasive storage hopper.
Remove the cage clamps and cage.
Block the blastwheel and remove the central fixing bolt.
Remove the impeller using a wooden or brass drift.
Remove the top liner cover and remove the top liner using a screwdriver or a
crowbar.
Clean the blast wheel and the blades with air
Through the opening of the blast housing: use a wooden or brass drift to tap out
all six blades from the blast wheel towards the center of the blast wheel.
Use a new central fixing bolt when mounting new blast wheel blades.
Replace the blades with six new ones and re-assemble the machine in reverse
order. Note: blast wheel blades must be replaced as a set. Replacing only some of
the blades can cause imbalance of the blast wheel.
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 hydraulic parts 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 save and
reliable machine.
Any guarantee on the machine is expired when:
By not using original Blastrac spare parts and abrasive.
When repair work is not done by qualified Blastrac personnel.
When changes, add ons or conversions are undertaken without written permission
of Blastrac BV.

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
