It is forbidden to drive on public roads when the blast unit + sideshift & adapter are mounted to
the front of the truck. Only when the truck is in hydro drive-mode it is allowed to drive short distances on a
slow pace with the blast unit + sideshift & adapter mounted to the front of the truck. Ignoring this command
will result in expensive damages to the machine and truck.
2. Machine description
2.1 Blast unit
The Blastrac blast cleaning machine 2-45D is a downward blasting machine with a closed abrasive circuit
exclusively designed for the pre-treatment of dry, frost-free, 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.

2.2 Separator, magnetic drum and hopper
The abrasive separator is mounted to the end of the recovery duct. It separates the abrasive from
contaminants and feeds the cleaned abrasive onto the magnetic drum(2). This magnetic drum functions as a
second separator for bigger particles and feeds the cleaned abrasive back to the abrasive storage hopper(7).
Two wire meshes are fitted to prevent any coarse contaminants from getting into the blast wheel. In order to
clean the wire mesh drawers, the drawers can be removed from the sides(8).

2.3 Blast wheel
The heart of the blast cleaning machine are two blast wheels that throw the abrasive onto the surface to be
cleaned by using centrifugal force. The blast wheels are placed in a protective housing lined with replaceable
wear parts. The blast wheels are driven by two hydraulic motors.
1 Control cage
2 Impeller
3 Blades (set of 6)
4 Blast wheel
Around the centre of the blast wheel there is the impeller feeding dosed quantities of abrasive onto the blades
of the turning blast wheel. On top of this is the control cage, which once it is carefully set, regulates the
throwing angle of the abrasive.
2.4 Abrasive sealing
Magnetic seals are fitted to the front and the sides of the blast housing outlet and are surrounded by rubber and
brush seals. At the rear there are four skid seals sliding over the floor.
The seals are employed to seal the blasting area in a way to avoid leakage of any abrasive.
The correct height adjustment of the magnetic seals (16-20 mm) is very important for optimum functionality of
the machine. The adjustment can be carried out by means of shaft nuts at the front and rear wheels.

2.6 Side shift and adapter
The side shift and machine adapter is designed to mount a
Blastrac 2-45D blast cleaning machine on a truck. During
blasting it is possible to shift the blast head from the total left
side to the total right side, outside the reach of the wheels of the
truck. This enables blasting as close to the sides as possible.
The side shift should only be used when the machine is moving
forward or backwards, or when the blasthead is lifted off the
ground. Using the side shift in standstill position with the
blasthead on the ground could damage the oil pump.
Don’t use the equipment for any other purpose than to mount a
2-45D blast cleaning machine to a truck.
Please note that the illustrations are simplified.
8
There are 4 hydraulic connections, 1 electrical connection and 2 sleeve
bolts to connect the side shift & adapter to the front of the truck.
The 4 hydraulic rotary couplings should be cleaned before and after
each use. Use brake cleaner or something similar to do so. Use the red
protection caps after each use.
Place a bucket underneath the couplings when connecting or
disconnecting them to catch the drops of oil that may be spilled.
The electrical connection on the truck has a clamp to lock the connector
in place, always use this to prevent any water or dust entering the
connector during work.
The electrical connection on the truck also has a protective cap, always
close it during transport.
The sleeved bolts should always be tightened firmly. Use the wrench
and socket wrench to do so.
2.7 Dust collector 2-45TDC
The 2-45TDC is a very powerful truck mounted dust extractor. This high performance machine is exclusively
designed and built to be used in combination with the Blastrac 2-45D blast cleaning machine. It is equipped
with 24 pieces of specially designed high quality Blastrac cartridge filters. The rotating valves transport all
generated debris directly into 2 BigBags for easy removal.
The Blastrac dust extractor 2-45TDC can only be used for dry cleaning.
It should only be used for removing noncombustible/non-explosive dust or substances.
The 2-45TDC may not be used for carcinogenic or pathogenic substances.
The machine is designed for usage in conditions according to classification M (see below).

The air streaming through the complete system during the application of
the blast cleaning machine and dust extractor has the following functions:
- Cooling of the blast wheels
- Cooling of the abrasive
- Transport of the abrasive
- Transport of dust through the system
- Separation of the dust from the re-useable abrasive
- Transport of the dust to the dust collector
The dust extractor is provided with an air pulse cleaning system which increases the life of the filter cartridges.
This system works by use of pressurized air, built up by a belt driven compressor. The air is led through a
water separator to the pulse system.
The conditioned air then passes a control valve which regulates the system pressure, and then builds up
pressure in the pulse tank.
The pressurized air is used to generate a pulse of air which cleans the filters from the inside. With every pulse
of the pulse system all dust and particles are released from the filter surface and end up in the dust hoppers
below the filters, where it travels through the rotating valves to be stored in big bags.
The electrobox controls all electronic components, the main switch should be turned off every time after the
job is done. The diagrams of the electrical system are placed inside the control panel.
The touch screen and the electrobox both have to be turned on for either of them to work.
The truck’s engine power is transmitted to the hydraulic PTO (13), to allow smooth
driving at low speeds and ensure high blasting power from the blast unit. The
hydraulic system runs at or below 250 bar.
During transport the blast unit has to be stored inside the truck. Use the safety
chains to secure it inside.
Inside the truck you will also find a toolbox mounted to the wall and a powder fire
extinguisher. This powder extinguisher is suited for: Solid materials (A), Liquids (B),
and Gasses (C). It is also safe to use on electrical components under current
(minding the collateral damage).

people.
f) The suitable precautions include decontamination before disassembling the dust collector, adequate
filtered ventilation of the exhaust air from the room in which it is disassembled, cleaning of the
maintenance area and suitable personal protection equipment.
g) The external parts of the dust collector must be decontaminated by cleaning and vacuuming methods, de-
dusted before being taken out from the hazardous zone. All parts of the dust collector must be considered
as contaminated when they are removed from the hazardous zone and appropriate actions must be taken
to prevent dust from dispersing.
h) When maintenance or repair procedures are carried out, all the contaminated elements that cannot be
properly cleaned, must be destroyed.
15
i) These elements must be disposed of in sealed bags according to the applicable regulations and in
accordance with the local laws governing the disposal of such material.
j) This procedure must also be followed when the filters have to be disposed.
k) If dust leaves the filter unit instead of clean air, this is a sign that the filter cartridges are damaged or not
fixed correctly inside the chamber.
l) When a filter is leaking it has to be replaced. The compartment above the filters and silencer also have to
be cleaned thoroughly.
m) Compartments that are not dust-tight must be opened with suitable tools and thoroughly cleaned.
n) A second person must be deployed who can disengage the hydraulics and switch off the PTO (Hydraulic
unit) in an emergency if work on live parts is necessary. The work area must be sealed off using a red and
white safety chain and a danger sign. For the electrical parts, use a tool that is insulated against voltages.
o) WARNING! Do not weld, flame cut or perform grinding works on or near the dust collector.
Danger of fire or explosion exists!
p) Provide adequate ventilation when working in a confided space.
q) Secure the maintenance area if necessary.
r) Failures due to inadequate or incorrect maintenance may generate very high repair costs and long
standstill periods of the machine. Regular maintenance therefore is imperative.
s) Operational safety and service life of the machine depends, among other things, on proper maintenance.
t) Prevent premature wear by keeping the machine as dust free as possible. Clean the machine for this
reason regularly with a dust collector and non-aggressive materials, never use a high pressure water
cleaner to clean the machine.
u) Do not use any aggressive cleaning materials! Use lint-free cleaning cloths!
v) The Gearbox settings menu indicates the time left before the gearbox should be serviced.
w) It is advisable to stock all spare parts or wear parts that cannot be supplied quickly. As a rule, production
standstill periods are more expensive than the cost for the corresponding spare part.
3.8 Hydraulic safety
a) Make sure all hydraulic hose connections are tightened and there is no leakage of oil.
b) Over tightening could damage O-rings. If a leak still persists, remove fitting and replace O-ring.
c) Make sure the hydraulic hoses have no damages, signs of wear and tear or other defects.
d) Hydraulic fluid under pressure is dangerous and can cause serious injury.
e) Hoses and pipe work can be under high hydraulic pressure. The temperature can be above 37° C. Use
only hoses and pipe work that are sized and marked in accordance with the overall power consumption of
the machine.
f) The system runs at or below 250 bar. Never look for a leak when the unit is under pressure.
g) Avoid leaks by keeping fittings and hoses tight, only check and service when not under pressure.
h) Leaking hydraulic fluid is not only unsightly, it’s dangerous. It could make workplace floors slippery,
contaminate the environment and could create a possible fire/explosion hazard.
i) Never change the oil pressure of the machine! Changing the oil pressure could cause serious damage to
the machine and could result in very dangerous situations!
j) Only work with the hydraulic oil in an area that is well-ventilated, otherwise you must wear suitable
respiratory protection. Always wear Personal Protective Equipment when handling the oil:
-Protecting gloves (preferably made of nitrile or neoprene.)
-Safety goggles.
-Hydrocarbon-proof clothing and safety shoes.
k) Avoid long and repeated contact with the skin, after contact wash thoroughly with water and soap.
Contact with eyes: Immediately flush eyes with cold, fresh water for a minimum of 15 minutes. Seek
professional medical attention.

3.11 Safety regarding magnets
The 2-45D blasthead and 2-45 TBS tow behind sweeper contain static magnets, none of them exceed the
Exposure Limit Values (0-1 Hz) of the DIRECTIVE 2013/35/EU on the minimum health and safety requirements
regarding the exposure of workers to the risks arising from electromagnetic fields. However, the Action levels
(ALs) for magnetic flux density of static magnetic fields could form a risk for workers at particular risk such as:
Workers wearing active implanted medical devices (AIMD)
Workers wearing passive implanted medical devices containing metal
Workers wearing body-worn medical devices
Pregnant workers
Static magnetic field Action Levels (AL)
An AL of 0.5 mT is specified to limit interference with the function of active implanted medical devices. The EMF
Directive also provides an AL of 3 mT to limit the projectile risk in the fringe field from strong sources (> 100 mT).
Workers with active or passive medical devices should be
careful around the Tow Behind Sweeper. The areas that
could pose a risk are indicated with warning signs. Keeping a
distance of 20 cm from the magnet of the Tow Behind
Sweeper will ensure the safety of workers with active or
passive medical devices.
During normal activities there should be little to no risk from
the magnet inside the 2-45D blasthead because of the design
and the way the magnets are encapsulated and shielded.
However, take caution when performing maintenance,
cleaning and / or repair because then the magnets could be
less shielded and thus forming a possible risk for workers
with active or passive medical devices.
Keeping a distance of 20 cm from the magnet
will ensure the safety of workers with active or
passive medical devices.

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.
4.1 Checkpoints:
Machine in general
Operating and safety 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.
Check all hydraulic components, connections and hoses for oil leakage, wear and/or damages.
Dust collector
Dust hoses must be undamaged and free of obstructions. The connections must be reliable: use hose
clamps and industrial tape.
Make sure that the Big Bags are empty and connected properly. Put a pallet underneath the BigBags.
The filter housing must be sealed in properly and all seals must be in good condition.
If dust leaves the filter unit instead of clean air, this is a sign that the filter cartridges are damaged or
not fixed correctly inside the chamber.
All water must be removed from the air tank and drain box. Excessive water can have a negative
impact on the pulse power and shortens the life-time of the filter cartridges.
Check all air hoses for leakage.
Blast unit
Check the following parts for damage and wear: blast wheels, feed spouts and liners. Wear will take
place in form of grooves along the blade surface outwards. Wear grooves are acceptable until 75% of
the blade thickness has been worn away. When this point is reached, replace all blades as a set.
Check the parts of the separator on wear and defects. Remove foreign bodies and dust deposits.
Check the level of abrasive in the storage hopper. Refill if necessary.
Check the front, side and rear magnet and brush seals for wear.
Work area
Check the surface to be treated for loose parts (stones, screws, etc.) The surface must be swept if
necessary. Make sure the machine can travel over all inequalities on the surface. Small inequalities like
weld seams or floor joints are no barriers for the machine
Secure the work area around the machine providing an adequate safety distance from the machine.
Use a red and white safety chain and danger sign to enclose the work area.
Remove reinforcing steel or other objects protruding from the surface in order to prevent damage to
the machine.
Warning! Make sure that the surface to be treated does not contain dangerous materials
such as: - combustible or explosive dusts or substances.
- carcinogenic or pathogenic substances.
