Applications
The BP-9-110 is an affordable 110V blast cleaning system designed both to complete
small to medium jobs and to act as a complimentary unit on larger jobs by specializing
in edge work and hard to reach areas. The BP-9-110 has a 9" blast pattern and has the
capability to remove 1/8" of depth in one pass. This portable, lightweight unit cleans and
profiles in one easy step. Shot sizes range from S-170 to S-390, which can be used in a
wide range of applications including small floor areas, tight spaces, balconies, garage
floors, basements, and pool decks. Wear parts are interchangeable with BLASTRAC
parts. The mechanics of the BP-9-110 are fairly simple. When the shot lever is
squeezed, a cable connected to the shot lever opens the shot valve which subsequently
allows shot from the shot hopper to be released. The shot then moves through the shot
valve, down the feed spout, and into the blast wheel which sits in a control cage. The
spinning wheel, which is powered by a 110V right angle motor, then spins the blast
wheel at a very high rate of speed which causes the shot to be thrown through an
opening in the control cage and down onto to the concrete surface that is being
cleaned. Due to the high rate of speed at which the shot is traveling, it acts to fracture
the concrete surface which consequently produces concrete dust. After hitting the
concrete surface, the shot rebounds off of it and, through a combination of the rebound
effect and the use of a vacuum, the shot and the concrete dust then move through the
blast housing. Because shot is heavier than concrete dust, gravitational force causes
the shot to be sent back into the shot hopper where it is continuously recycled by the
machine. As for the concrete dust, it is sucked into a duct hose which travels from the
blast housing to the dust collector. After traveling through the duct hose, the concrete
dust is deposited in the dust collector's dust bin.

General
All operators & maintenance personnel should read this section carefully before operating
or maintaining this equipment. These safety instructions are not meant to represent an
all-inclusive list of instances which could occur when operating this equipment. For, as
with any piece of construction equipment, serious injury can occur if proper safety
procedures are not diligently followed. All safety & warning labels posted on the machine
must be followed as well as the safety program instituted by your company. There is no
substitute for sound judgement in the operation & maintenance of this equipment. In
cases where operating personnel have insufficient knowledge or understanding of the
English language, proper translated training must be completed before use of this
equipment can take place. This manual must be kept with the machine at all times so as
to allow the operator easy access to its vital information. The united states department of
labor’s occupational safety & health administration (OSHA) provides statutory
requirements, standards, & regulations relating to the use of portable tools on
construction sites. These statutory requirements, standards, & regulations are posted on
the osha website at www.osha.gov. The operator & maintenance personnel should
understand & follow these statutory requirements, standards, & regulations.
Work Site Assessment & Inspection
Before starting blasting operations, a site assessment must be performed. During the
site assessment verify the following:
1. Work area is flat, clean, & dry, free of debris, frost-free, & has no flammable liquids
nearby.
2. Make sure that the machine will be able to clear all obstructions. Never blast a wet
floor.
3. Never blast over bolts, nuts, screws, nails, or other debris as this may result in
significant damage to the machine & serious injury to the operator.
4. Work area is well ventilated. If work area is enclosed or partially enclosed
(warehouse, parking garage, tunnels, etc.), then gasoline can never be used as
the fuel source for the shot blasting machine. This is because carbon monoxide,
which is a byproduct all internal combustion engine, can be extremely hazardous
when allowed to accumulate in an area. An odorless, tasteless, & non-irritating
gas, carbon monoxide can quickly become lethal. As a result, vapor propane must
be used in all instances when the work area is enclosed or partially enclosed. The

BP-9-110 Machine Manual

work area must still be well ventilated, however, as vapor propane also releases
carbon monoxide. This means that extreme caution must still be used when using
this fuel source.
5. Each worker has a carbon monoxide monitor on their persons. These carbon
monoxide monitors should be calibrated, in working order, & should be equipped
with audible alarms that will warn workers if carbon monoxide levels become too
high. If carbon monoxide levels exceed 35 parts per million, all work must cease
immediately. This represents a potentially deadly situation which necessitates an
immediate shutdown.
6. All operators & other personnel within the work area have received training on
proper ventilation procedures & on proper operation procedures for the engine &
for other types of equipment.
7. Floors have been thoroughly inspected. Some floor or deck surfaces may be
coated with or contaminated by dangerous materials such as:
•PCBs
•Lead
•Asbestos
•Pesticides
•Solvents
•Cleaning fluids
•And/or other harmful chemicals
The dust produced from shot blasting such surfaces can create a serious health threat
to those who inhale or come into contact with the dust. The work area must be checked
for these materials before work can begin. Blastpro manufacturing, inc. does not
warrant its equipment to be suitable for, or approved for, removing dangerous materials.
It is therefore the responsibility of the contractor to confirm the safety of the work area &
the equipment with the proper authorities. It is also the responsibility of the contractor to
warn all staff members of all the potential short-term & long-term health risks associated
with inhaling & coming into contact with dangerous materials. The contractor is
responsible for protecting all workers from being exposed to dangerous materials. Since
the shot blasting machine has not been designed to remove, clean, profile, or alter any
surface coated with or otherwise contaminated by dangerous materials, Blastpro
Manufacturing, Inc. expressly disclaims any liability for injury, illness, death, or damage
that might occur or result from such improper use.
8. Operator & any other personnel in the work area are wearing safety glasses with
side shields, dust masks, ear plugs, hard hats, steel toed work boots, long sleeved
shirts, tight fitting clothing, & gloves. It is also imperative for staff to tie back long
hair & to remove all jewelry.

12.All glass & equipment, including vehicles, are protected from steel shot. This can
be done by loosely hanging a sheet of visqueen or other protective materialin front
of the glass or equipment in a curtain-like fashion. The importance of protecting
glass & equipment from steel shot cannot be overemphasized.
13.Plug or cover all floor drains to prevent steel shot from falling into the drains.
14.This equipment is onlyto be used for commercial purposes. This equipment is only
to be operated by professional, trained, & competent operators.
15.The operator must be aware of their surroundings & use common sense. The
operator is not to operate the equipment if he is tired, distracted, or under the
influence of drugs, alcohol, or medication that decreases awareness.
Start-Up Safety Procedures
After performing the site assessment safety procedures listed above, bring the shot
blasting machine to the work area & perform the following procedures:
•Verify that personnel are competent & that they have read & understood the safety
information in this manual. Staff must also be familiar with how to operate the
machine & with all of its components. Make certain that all personnel follow all
safety instructions & programs required by their company & by the worksite.
•Before putting the shot blasting machine in operation, make certain that the belt
guards are in good condition.
•Inspect the shot blasting machine & dust collector for damage, tears, or other signs
of wear.
•Verify that all fittings & hoses are tight.
•Inspect the dust collector. Verify that the dust bin is empty, filters are clean & clear
of debris, & motors & fansare in working order. The dust collector must be emptied
at the end of each job.
•Make certain that the shot valve control lever is closed except when the machine
is actually in operation.
•Inspectall electrical cords on the shot blasting machine fordamage, tears, or other
signs of wear. If electrical cords are damaged, then do not attempt to perform
blasting operations until cords have been repaired or replaced.
•Inspect the duct hose leading from the shot blasting machine to the dust collector.
Make sure hose is free of debris, hose is not cracked & that holes do not exist. If
necessary, replace hose.
•Make certain that all screws & other fasteners are tight.
•Check the shot storage hopper, the feed spout, & the blast wheel for foreign bodies
& remove them if present.
•Check theblast wheelblades, control cage, liners, & magnets for damages & wear.
Wear grooves are acceptable until 50% of blade thickness has been worn away.
When blade thickness has been worn away by more than 50%, replace all blades.
•Check the front, side, & rear seal system & brush seals for excessive wear.

•Check the tightness of the hose connections & the condition of the hose to the
filter.
•Check the electrical connections for dirt & foreign body deposits.
•Verify that the electrical motors are free of dirt & other contaminants.
•Check the level of shot in the storage hopper. Refill hopper if necessary.
•Verify that the main power cable & the dust hose are free of damage. Replace or
repair all damaged parts before putting the machine into operation.
•Check to confirm that all machine parts are assembled safely & correctly. It is
recommended to have original spare parts & wear parts on hand. It is imperative
that the machine receive special attention & regular maintenance in order to
function properly & to operate safely.
•Connect the blast cleaning machine & the filter unit with the dust hose. Use hose
clamps at the connections.
•Connect the supply cable of the blast cleaning machine with filter unit. Connect the
electrical cable of the filter unit with the site supply.
•Make certain that the side seals are positioned correctly.
•Check that the filter dust container has been emptied.
•Always blast in a straight line away from the dust collector. Blasting in a straight
line will produce the most uniform results. Never run over anything with shot
blasting machine. Running over an extension cord, air lines, rebar expansion
joints, openings in floor, drains, etc. With the shot blasting machine can result in
serious injury to the operator and/or damage to the equipment.
•Make certain to keep hands away from all moving parts once the machine is in
operation.
•Make certain to never stand next to the blast housing while the shot blasting
machine is in operation as blade failure could result in serious injury.
•Make certain that the shot hopper door is closed while the machine is in operation
as the shot blasting machine throws shot which could present a serious danger if
the shot hopper door is not properly closed.
•Make certain that the blast seals of the shot blasting machine are not worn out. As
these seals provide the suction that is required by the machine, they will become
dislodged if they become worn out. This will then result in shot being discharged
from the machine. It is consequently recommended that the operator make
absolutely certain that the blast seals are in good working condition before putting
the shot blasting machine into operation.
•In the unlikely event of a failure, turn main power switch to the OFF position &
make certain that the shot blasting machine & the dust collector have been
disconnected from all power sources.
If the shot blasting machine is operated using a generator as the power source, the
generator must be operated in accordance with the current VDE directives (this
applies to the protective earth conductor in particular) in order to ensure that all safety
devices are functioning & to eliminate possible damage to electrical components.

Operational Safety Procedures
When operating the shot blasting machine, perform the following safety procedures:
•The shot blasting machine shall not be put into use unless it is attached to an
appropriate exhaust hose & dust collector.
•Never operate the machine while the electrical panel door is open.
•Support personnel must keep a safe distance from the machine while it is in
operation. Do not stand in front of the machine while it is in operation.
•Since the speed of the machine determines the depth of its cut, it is advised that
the operator run a test pattern. Failure to run a test pattern could result in the
machine gouging the floor.
•The blast pattern needs to be inspected by the operator at least every ten feet as
variation in concrete means that the concrete or the coated surface may be softer
in some areas than it is in others.
•Whenever the dust collector becomes full, it must be emptied. Failure to empty the
dust collector could result in the machine losing its suction to the floor. If this
happens, then all of the shot will fall out of the shot hopper.
•Never switch off or remove the exhaust & ventilation devices when the machine is
in operation.
•A second person must be present so as to pull out the machine’s plug in an
emergency. The work area must then be sealed off using a red & white safety
chain & a danger sign. Use a tool that is insulated against voltages.
•Make certain circuit breakers can handle the electrical load required by the
machine.
•If an error occurs while the machine is in operation, it must be shut down
immediately. The cause of the error must be established immediately.
•If cables become loose or scorched, the machine must be shut down immediately.
Shut-Down Safety Procedures
When shutting down the shot blasting machine, always perform the following safety
procedures:
•Shut off the shot supply by pulling the shot valve handle backwards.
•Advance the machine until you are sure that no deep holes are being blasted into
the surface.
•Turn off the breakers to the shot blasting machine & to the dust collector.
•Turn off the shot blasting machine as well as the dust collector & disconnect both
from all power sources.
•Empty all dust from the dust collector. When removing dust from dust collector,
always wear a particle mask. Concrete dust may contain particles which are
extremely hazardous! These particles should never be inhaled!
•Empty all shot from the shot hopper on the shot blasting machine. Shot should
never be left in shot blasting machine after work is performed. Never move or

transport shot blasting machine with shot in the shot hopper as this may result in
damage to the equipment.
•Make certain that all dust has been removed from the dust hopper. Dust left in the
dust hopper has the potential to catch on fire and/or explode without notice.
•After completing work, clean all stray shot from work area. Shot can be cleaned
with a magnetic broom or with a shop vacuum. Never leave stray shot in work
area as shot represents a slip & fall hazard. Stepping & falling on steel shot can
result in serious injury or even death.
Maintenance Safety Procedures
When performing maintenance on the shot blasting machine, make certain that the
following safety procedures are followed:
•Verify that the shot blasting machine & the dust collector are not in operation.
Attemptingto performmaintenanceoperationson theshot blastingmachineand/or
the dust collector while they are in operation can lead to serious injury or death.
•Make certain that the shot blasting machine is in the safety off position (valve is
closed, blast machine is switched off, dust collector is switched off, all drives are
at a standstill, & main plugs have been pulled).
•Never connect or disconnect power cables when voltage is present or while under
load.
•Make sure that the shot blasting machine is on a level & stable surface.
•Allow the blast wheel to stop completely.
•Verify that all moveable parts of the shot blasting machine are completely still &
secured against accidental movement.
•Make certain that all maintenance personnel are wearing lint-free cleaning cloths.

licensed electrician.
•Failure to replace loose or damaged parts could cause damage to the equipment
and/or serious injury or death to the operator.
•All replacement electrical components are to be identical to the components
originally supplied with the shot blasting machine. Substitution of these parts with
other electrical parts can result in damage to the shot blasting machine & injury to
those nearby.
•All replacement electrical components are adjusted correctly.
•Make certain that electrical equipment is inspected regularly.
•All other repairs must be completed by competent, qualified personnel.

11
10.Make sure that any hardwiring or circuit breaker changes are performed by a
licensed electrician.
11.Before loading the steel shot into machine, turn the switch on the BP-9-110V and
the dust collector to the ON position for two minutes so as to verify that the circuit
breaker will not trip.
12.Disconnect the hose from the BP-9-110 to verify that the dust collector has proper
suction.
13.After verifying proper suction, reconnect the hose to the BP-9-110V.
14.Check the seals on the BP-9-110V to verify that the seals are set at the proper
height. The seals should be rubbing the surface of the concrete or steel.
15.Place a handful of steel shot in front of the BP-9-110V.
16.Push the BP-9-110 over the handful of steel shot. This will attach the steel shot to
the magnetic seals and prevent shot from escaping from the BP-9-110V.
17.Pour steel shot into the BP9-110 shot hopper to the bottom of the screen.
18.Turn the switch on the BP-9-110 to the ON position, squeeze the shot valve to
openthe shotvalve,andpushtheBP-9-110.Verifythat theblast patternis uniform.
If blast pattern is uniform, then proceed to step #17. If blast pattern is not uniform,
then release the shot valve handle to close the shot valve, turn the switch on the
BP-9-110 to the OFF position, and proceed to step #15.
19.Adjust the control cage.
20.Turn the switch on the BP-9-110V to the ON position, squeeze the shot valve
handle to open the shot valve, push the BP-9-110, and verify that the blast pattern
is uniform.
21.Once blast pattern is uniform, start shot blasting.
Setting the Blast Pattern:
Setting the proper blast pattern is determined by trial & error. The importance of selecting
the proper blast pattern cannot be overstated. An improper or unevenly distributed blast
pattern will result in excessive blasting on either the right side or left side of the machine
& will leave shadows or “track” lines in the blast pattern.
1. Verify that the blast wheel is rotating in the direction shown on the blast housing.
2. Place a sheet of steel approximately ¼” thick under the machine & then blast with
the shot valve fully open for approximately 30 seconds. Do not move the machine
during this time.
3. Afterblasting forthirtyseconds, shutdown the machine & inspect the blast pattern.
The “hot spot” should be in the center of the width blasted. The “hot spot” can be
altered by rotating the control cage in small increments. Rotating the control cage
in a counter-clockwise direction will move the “hot spot” to the right while rotating
the control cage in a clockwise direction will move the “hot spot” to the left. If you
visualize a clock, the opening of the control cage should be set at approximately
11:00 (leading edge) & 9:00 (trailing edge) on the clock. The size of steel shot used
will impact where the “hot spot” appears in the blast pattern.The operator will need
to adjust the control cage based upon the size of steel shot utilized.

BP-9-110 Machine Manual

12
The setting of the control cage will vary depending both on the size of shot used & on the
type of surface being blasted. When altering the position of the control cage, make sure
to only adjust it in small increments. Keep adjusting the control cage until the desired blast
pattern has been obtained. Once the desired blast pattern has been obtained, the blast
pattern should remain consistent. Four factors may affect the blast pattern. Of these, the
control cage setting is the most crucial. Otherfactors that mayalso affect theblast pattern
include the size of the shot being used, the wheel rotation, & the worn wheel kits. If
adjusting the control cage setting does not allow the desired blast pattern to be achieved,
then it is important to narrow down what is causing the problem. First, take into
consideration the size of shot being used. If this does not resolve the problem, then check
and, if necessary, replace the wheel rotation & the worn wheel kits. The proper control
cage setting is described in the following figure:
Shut Down:
1. Close the shot valve.
2. Stop the shot blasting machine forward & turn the speed control knob to zero.
3. Turn off the blast wheel.
4. Turn off the shot blasting machine.
5. Turn off the dust collector.
6. If this is only a temporary stoppage, then check the dust collector & empty it if
necessary. If this stoppage is the result of being done for the day, then empty the
dust collector no matter the amount of dust within it.
7. If this is only a temporary stoppage, then check the shot hopper & empty it if
necessary. If this stoppage is the result of being done for the day, then empty the
shot hopper no matter the amount of shot within it.
8. Make certain that the shot blasting machine is in a safe location if it is to be left at
the job site. If the shot blasting machine is to be transported, then please refer to
the section in this manual that addresses “Transportation.”

Transportation
When transporting the shot blasting machine, it is strongly recommended that personnel
act in a manner so as to reduce the potential that damage takes place as a result of using
excessive force or of using incorrect loading & unloading procedures. Personnel must
remove any shot from the machine before it is transported. Also, the machine may only
be lifted by using the suspension eyelets; forklifts should never to be used to transport
the shot blasting machine.
Dust Collector Function
The most fundamental part of the dust collector is referred to as the filter chamber. Air
containing dust particles enters the filter chamber from the blast head via the exhaust
hose. This air then moves into the dust collector inlet connection located on the left, front
side of the dust collector. Next, the air passes through a plenum & moves through filter
cartridges. These filter cartridges capture the dust particles & prevent them from moving
on with the air. Now dust-free, the air then passes to the clean air portion of the dust
collector where it is subsequently released back into the environment by way of the
silencer box.
Dust Collector Maintenance
The dust collector must be examined habitually. This is because adequate ventilation is
essential for the dust collector. It is therefore vital that the following areas are routinely
examined:
•Adequate ventilation is available at all times. Ventilation irregularities can have a
negative effect on the efficiency of both the shot blasting machine & the dust
collector. Poor ventilation results in excessive wearing of the blast wheel & liner
wear. Despite conventional wisdom, shot is not the primary cause of wear & tear
to shot blasting machines. In actuality, it is the dust & other contaminants produced
by these machines thattypically cause their parts to wear prematurely. As a result,
it is essential that proper ventilation be supplied to the machine at all times by
keeping the dust collector free of excessive contamination.
•The hose connections between the blast head & the dust collector must be tight.
•The hose must be in good condition. Flattened spots, holes, & wear spots should
be corrected without haste. Hose must be replaced if necessary.
•Filter cartridges must be kept in good, working condition.
If the dust collector is not in proper, working order, then this can have a detrimental effect
on the entire system. Improper ventilation can result in inadequate abrasive cleaning
which hastens blast wheel & liner wear. It is, consequentially, essential that the dust
collector be well maintained. A dust collector that receives timely, regular maintenance
will result in less shot contamination which will help to both reduce operating costs &
increase overall effectiveness. Before inspecting or removing filter cartridges, make sure
that the shot blasting machine shot blasting machine is on a level surface. Also, make

14
sure that the machine has been properly immobilized. Finally, verify that shot blasting
machine is in the off position & has been disconnected from all power sources.
Inspection Timetable
The shot blasting machine contains parts that are continually exposed to steel shot
moving at high rates of speed. The combined effect of contact with steel shot traveling at
high rates of speed & exposure to concrete dust causes these parts to deteriorate. As a
result, the operator or maintenance personnel should inspect the machine wear parts
prior to operation & replace these parts when necessary. Wear parts & inspection times
on the machine, other than inspection prior to use, are listed below:

in the same working condition as when they were new. If they cannot be repaired, then
they should be replaced immediately. Prior to any repair work, secure the machine
against unintentional switching-on. Put the machine in the safety off position. The
supplier’s operating & maintenance instructions should also be followed during service &
maintenance procedures.

repaired so that they are in the same working condition as when they were new. If they
cannot be repaired, then they should be replaced immediately.
Blast Wheel Removal & Installation
When theblades on the blast wheel aredeteriorated by50% or more, then theblast wheel
should be replaced. To replace the blast wheel, perform the following steps:
1. Verify that the shot blasting machine is turned off & disconnected from all power
sources.
2. Remove the feed spout & the control cage.
3. Remove the four mounting nuts, flat washers, & lock washers that secure the
control cage mounting assembly to the blast housing. Do not loosen any other
screws on the control cage mounting assembly since they are used to set the gap
between the blast wheel & the control cage. Remove the control cage mounting
assembly.
4. Remove the socket head cap screw & lock washers from the blast wheel & remove
the blast wheel.
5. Check the wheel hub for wear & replace if necessary.
6. Install new blast wheel using the new socket head cap screw & lock washers that
are included in the wheel kit. Be sure that the new blast wheel is seated properly
on the wheel hub before tightening the socket head cap screw.
7. Reinstall the control cage mounting assembly to the blast housing.
8. Install the new control cage that was included with the wheel kit. Rotate the wheel
by hand to be surethat the control cage &the wheeldo no touch.The initial window
setting for the control cage should be between 8:30 & 10:30.
9. Reinstall the feed spout.
10.Energize the blast motor momentarily to check for good balance & proper
clearance before shot blasting.
11.See the section in this manual about “Setting the Blast Pattern” before adjusting
the control cage.
Only blast wheels manufactured by Blastpro Manufacturing, Inc. should be used by the
shot blasting machine. Other blast wheels that have not been tested by Blastpro
Manufacturing, Inc. could result in damage to the equipment or injury to the operator.

Fault Diagnostics
Problem
Solution
Breaker is tripping
when BP-9-110 and
dust collector are
turned to the ON
position.
The BP-9-110 and dust collector should be powered by
separate breakers. Find electric outlets with separate
breaker switches and use accordingly. Check circuit
breaker sizes.
BP-9-110 is vibrating
excessively.
Check blast wheel immediately. Excessive vibration is
usually caused by the blast wheel being out of balance due
to it being worn or by blades being broken or chipped.
Install new blast wheel kit. Failure to install new wheel kit in
this instance could lead to serious damage to machine.
BP-9-110 is creating
excessive noise.
This problem is most likely caused by an improper
alignment of the blast wheel and control cage. Check
alignment of blast wheel and control cage immediately and
verify that there is adequate clearance between the blast
wheel and the control cage.
BP-9-110 is creating
excessive wear on
liners and blast
housing.
Adjust control cage so that the "hot spot" is centered in
work area rather than on liners or housing.
BP-9-110 is dropping
an excessive amount of
steel shot.
Verify "hot spot" is centered properly and adjust control
cage as necessary. Verify seals do not have excessive
wear, feed spout is aligned properly, and shot valve is
closing when shot lever is released. Verify dust collector
has adequate suction.
The blasting
performance of the BP-
9-110 has diminished.
Verify that there is an adequate amount of steel shot in the
shot hopper and that shot is free of concrete dust or other
contaminants. Verify there are no obstructions in the shot
valve or feed spout and the feed spout is properly aligned.
Verify that the shot valve is opening properly. Verify that the
blast wheel and the control cage are not excessively worn.
Verify dust collector has adequate suction.
The BP-110 is difficult
to push or gets stuck in
areas.
Verify that the seals are positioned properly and that they
are not too close to the floor. Raise height of seals.
The steel shot in the
shot hopper contains
an excessive amount of
concrete dust.
Verify that the vacuum has good suction. If this does not
resolve problem, then increase the travel speed of the BP-
9-110V to reduce amount of concrete being removed. If this
does not produce an adequate profile, then make additional
passes over the floor surface.

The BP-9-110 or dust
collector is emitting
concrete dust.
Verify there are no holes in the duct hose leading from the
BPS-110V to the dust collector. Verify filters in the dust
collector are properly installed and are clean. If necessary,
replace filters in dust collector.
Steel shot is being
sucked into dust bin. Dust collector is producing too much suction for the size of shot being used. Restrict air flow on dust collector.
