BP-10-27

SECTION 1.1: APPLICATIONS
The BP-10-27 shot blast machine is specifically designed for horizontal
applications. It is designed to simultaneously remove material, clean and profile
the substrate.
The BP-10-27 shot blast machine runs on a Kohler 27 hp lp motor
When in operation, the machine continuously recycles shot so that up to 1,500
square feet of surface area can be cut per hour while achieving a brush blast. To
accomplish this feat, the machine first moves shot from the shot valve into the
blast wheel. After being thrown by the blast wheel onto the surface below the
machine, the shot and the debris then rebound up to the dust separator where
the dust is automatically transferred to the dust collector. Next, the shot returns
to the shop hopper where it is once again passed through the machine. The BP10-27 constantly recycles the shot from the time the shot valve is opened until
the time when the shot valve is closed by the operator by the operator. While the
machine is in operation, the auto pulse dust collector cleans all six cartridge
filters.

MACHINE MANUAL
SAFETY

BP-10-27

SECTION 2.1: GENRAL
Read and understand this Machine Manual prior to operating or performing
maintenance on the BP-10-27.
This Machine Manual has been developed as a guideline for machine operation.
It is not a substitute for proper organizational training and management.
All machine operators and maintenance personnel should be properly trained in
operation and safety features of the BP-10-27.
Make these operating instructions accessible to all operating and maintenance
personnel.
Never weld, modify, cut or grind components of the BP-10-27 without prior
written consent from the manufacturer.
Never use aggressive cleaning chemicals to clean the machine.
All operators and maintenance personnel should receive training on the dangers
of carbon monoxide, or CO. All personnel should be able to identify signs and
symptoms of CO poisoning. Common signs associated with overexposure
include headache, nausea, weakness, dizziness, lethargy, visual disturbances,
and changes in personality and/or loss of consciousness.
SECTION 2.2: MAINTENANCE AND WEAR PARTS REPLACEMENT MODES
Maintenance mode is defined as placing the machine in a configuration, which
minimizes potential electric, hydraulic or stored energy hazards.
In general, the machine should be placed in Maintenance Mode prior to
performing any maintenance and/or troubleshooting activities.
MAINTENANCE MODE:
1. Move the machine to a level surface.
2. Reduce machine RPM to low idle.
3. Turn key switch to “OFF” position.
4. Remove key from switch to prevent accidental or unintended starting.
5. Block wheels to prevent the machine from moving.
6. Turn the LP bottle valve to “CLOSED” position.
7. Allow engine and exhaust tube to cool down prior to carrying out any
maintenance work.

MACHINE MANUAL
SAFETY

BP-10-27

In general, the machine should be placed in Wear Parts Replacement Mode prior
to changing the blade(s).
WEAR PARTS REPLACEMENT MODE:
1. Move the machine to a level surface.
2. Raise the blast head to the upper most position.
3. Reduce machine RPM to low idle.
4. Turn key switch to “OFF” position.
5. Remove key from switch to prevent accidental or unintended starting.
6. Place jack stands or blocks under blast head to ensure it does not move
down.
7. Verify all rotating parts have stopped moving and are secured against
unintended movement.
After performing any maintenance or repair work verify that all safety labels,
guards, lids and bolted connections are properly and securely installed on the
machine.
SECTION 2.3: WORK SITE ASSESSMENT AND INSPECTION
Before starting blasting operations, a site assessment must be performed.
During the site assessment verify the following:
•

•

Work area is flat, clean, and dry, free of debris, frost-free, and has no
flammable liquids nearby. Also, make sure that the machine will be able
to clear all obstructions. NEVER BLAST A WET FLOOR. NEVER
BLAST OVER BOLTS, NUTS, SCREWS, NAILS, OR OTHER DEBRIS
AS THIS MAY RESULT IN SIGNIFICANT DAMAGE TO THE MACHINE
AND SERIOUS INJURY TO THE OPERATOR.
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 BP-10-27 SHOT BLASTING MACHINE. This
is because carbon monoxide, which is a byproduct all internal combustion
engines, can be extremely hazardous when allowed to accumulate in an
area. An odorless, tasteless, and non-irritating gas, carbon monoxide can
quickly become lethal. As a result, liquid propane must be used in all
instances when the work area is enclosed or partially enclosed. THE
WORK AREA MUST STILL BE WELL VENTILATED, HOWEVER, AS
LIQUID PROPANE ALSO RELEASES CARBON MONOXIDE. THIS
MEANS THAT EXTREME CAUTION MUST STILL BE USED WHEN
USING THIS FUEL SOURCE.

BP-10-27

Each worker has a carbon monoxide monitor on their persons. These
carbon monoxide monitors should be calibrated, in working order, and
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.
All workers have received training on the dangers of overexposure to
carbon monoxide. Staff members must also be able to identify all of the
signs and the symptoms associated with carbon monoxide poisoning.
This training should ensure that work would stop immediately and
emergency medical personnel would be notified promptly if one or more
workers exhibited or complained of any of the common signs and
symptoms associated with carbon monoxide overexposure, including:
headache, nausea, weakness, dizziness, lethargy, visual disturbances,
changes in personality, and/or loss of consciousness.
All operators and other personnel within the work area have received
training on proper ventilation procedures and on proper operation
procedures for the engine and for other types of equipment.
FLOORS HAVE BEEN THOROUGLY INSPECTED. SOME FLOOR OR
DECK SURFACES MAY BE COATED WITH OR CONTAMINATED BY
DANGEROUS MATERIALS SUCH AS:
o
o

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 INHAIL
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

FOR PROTECTING ALL WORKERS FROM BEING EXPOSED TO
DANGEROUS MATERIALS. SINCE THE BP-10-27 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.
Operator and 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, and gloves. It is also
imperative for staff to tie back long hair and to remove all jewelry.
Work area has been blocked off to pedestrians, unprotected personnel,
and untrained personnel.
In the event pedestrians, unprotected
personnel, or untrained personnel enter the work area, blasting operations
are to be stopped immediately.

MACHINE MANUAL
SAFETY

BP-10-27

SECTION 2.4: PERSONAL PROTECTIVE EQUIPMENT
All personnel working with, or in the vicinity of the BP-10-27 should, at a
minimum, utilize the following PPE:
•
•
•
•
•

Protective boots or shoes
Eye protection with side shields
Hearing protection
Appropriate respiratory protection
Protective leather gloves for handling blades

Additionally, all personnel should utilize a carbon monoxide monitor while
working indoors. The BP-10-27 utilizes an internal combustion engine, which
produces carbon monoxide, or CO. CO can be fatal at high exposure levels. In
addition to CO monitoring equipment, the work site should be properly ventilated
to minimize exposure potential.
All personnel should observe PPE requirements particular to each job site.
SECTION 2.5: OPERATIONAL
When operating the BP-10-27, perform the following safety procedures:
•

•

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 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.
If the gap between the blades and the wear bar is 3/16 of an inch or
greater, then shot will begin to fall out of the machine. Eventually, all shot
will escape if the gap between the blades and the wear bar remains at
3/16 of an inch or greater.

SECTION 3.1: START-UP
Only trained, authorized personnel should be allowed to run the BP-10-27. If
training is needed, please consult with your Blastpro Manufacturing
representative or authorized distributor.
Prior to start-up, the work surface should be inspected for hidden studs, electrical
boxes, or any other hidden obstructions. These items should be removed or
clearly marked so they can be avoided.
To move machine:
1. Verify that LP bottle is installed and has fuel in it.
2. Verify that the LP bottle valve is turned to the “OPEN” position.
3. Operator should be firmly seated in the operator’s seat.
4. Turn the key switch to start until the motor starts (SEE FIGURE 3.1.1).
5. Increase the RPM enough to move the machine, but not to full throttle.
6. Only raise the blast head enough to clear obstacles. Some abrasive may
escape, so it is important to minimize the gap between the seals and the
surface.
7. Push lever forward to move forward; pull backward to reverse and use the
steering wheel to guide the machine.
8. Move machine to desired location.
Normal Operation:
1. Verify that personnel are competent and that they have read and
understood the safety information in this manual. Make certain that all
personnel follow all safety instructions and programs required by their
company and by the worksite.
2. Verify that the BP-10-27 is on a level, clean, debris-free, and dry surface.
3. Verify that the dust bin in the dust collector is empty.
4. Open propane tank valve.
5. Sit down in the seat of the BP-10-27.
6. Ground drive control lever is centered.
7. Make sure that the throttle is pushed all the way down.
8. Adjust throttle by pulling up on the throttle control.
9. Lock throttle for shot blasting by turning the throttle clockwise.
10. Turn the ignition switch to the ON position.
11. To steer the machine, rotate the steering wheel in the desired direction.
12. Start moving the machine forward and then slowly open up the shot valve
(the slower the machine moves while the blast wheel is engaged, the
deeper the cut will be to the underlying surface).

13. When arriving at a stopping point, shut off the shot valve about ten feet
before stopping the machine. Performing this operation will clear the
machine’s housing of shot which will prevent the BP-10-27 from blasting a
hole in the underlying surface when it comes to a complete stop.
14. Turn ignition switch on BP-10-27 to the OFF position.

•

Wear Bar: Before operating the BP-10-27, the wear bar clearance must
be checked by the operator. The wear bar should have 3/16 of an inch of
clearance for all applications in order to ensure the best blasting results.
After adjusting the wear bar, it is highly recommended that the operator
spin the blast wheel to make certain that all blades have clearance.
Vacuum Adjust Plate: This plate allows the operator to adjust the amount
of vacuum force that is pulled through the blast housing. It can be
adjusted to alter the amount of air flow allowed. Located within the shot
hopper, opening this plate allows more vacuum force and air flow. Closing
this plate, conversely, dampens/restricts the vacuum force and air flow.
Front End Lift: Although used primarily for loading and unloading the BP10-27, this feature can also be used to adjust the blasting seals while the
15

machine is in operation. This allows the operator to adjust the seals
without having to stop the machine and manually manipulate the seals.
Seals: In order to set the seals to the correct height, first make sure that
the machine is on a level surface. Then, put the BP-10-27 in a slow
forward motion. Next, bump the machine lower switch until the front seal
touches the surface being blasted and bends slightly. Finally, stop the
machine and assure that the side seals are also touching the floor.

Additional Operational Considerations:
•

•

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 pattern needs to be inspected by the operator at least every ten feet

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.
If the gap between the blades and the wear bar is 3/16 of an inch or
greater, then shot will begin to fall out of the machine. Eventually, all shot
will escape if the gap between the blades and the wear bar remains at
3/16 of an inch or greater.
HYDRAULIC FLUID UNDER PRESSURE IS DANGEROUS AND CAN
CAUSE SERIOUS INJURY OR EVEN DEATH! WHEN IGNITED,
HYDRAULIC FLUIDS CAN EXPLODE AND/OR CAUSE FIRES.
THE HYDRAULIC SYSTEM RUNS AT OR BELOW 500 PSI, NEVER
LOOK FOR A LEAK WHEN THE BP-10-27 SYSTEM IS UNDER
PRESSURE. HANDS SHOULD NEVER BE USED TO LOOK FOR A
LEAK WHEN THE SYSTEM IS UNDER PRESSURE. EVEN A PINHOLE
LEAK CAN CAUSE SERIOUS INJURY. THE LEAK COULD BE
ALMOST INVISIBLE WHEN ESCAPING FROM A PINHOLE-SIZED
LEAK. ESCAPING HYDRAULIC FLUID UNDER PRESSURE CAN
PIERCE THE SKIN AND ENTER THE BODY. NEVER ALLOW
PERSONNEL TO TOUCH ANY HYDRAULIC LINE OR FITTING WITH
ANY PART OF THEIR BODY WHEN THE SYSTEM IS UNDER
PRESSURE.

SECTION 3.2: SHUT DOWN
At end of shift or work day:
1. Move machine to level ground for storage.
2. Lower the blast head until the seals just touch the surface.
3. Lower RPM to low idle.
4. Turn key switch to “OFF” position.
5. Remove key to protect against unauthorized operation.
6. Turn the LP bottle valve to “CLOSED” position.
For long term storage:
The steps for long term storage are the same as the end-of-shift/day procedures,
with a few additions. For long term storage, the LP tank should be removed and
stored in a secure location. Additionally, the BP-10-27 should be covered to
protect it from dust and moisture.
Additional Steps for Machine Shut Down or Storage:
•

•

Empty 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 BP-10-27. Shot should never
be left in BP-10-27 after work is performed. Never move or transport BP10-27 with shot in the shot hopper as this may result in damage to the
equipment.
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 AND FALL HAZARD!
STEPPING AND FALLING ON STEEL SHOT CAN RESULT IN
SERIOUS INJURY OR EVEN DEATH.

SECTION 3.3: SHOT SELECTION
The BP-10-27 can utilize a variety of shot. Selection of shot is important to
achieve the most efficient removal, cleaning and profiling of the surface.
Incorrect shot selection can lead to increased production times and cost.
In general, if the machine is being used to simply profile a surface, a smaller shot
size should be used. This will provide more impacts per square inch, resulting in
a better profile.
If the job calls for heave removal, a larger shot size should be used. This will
result in fewer impacts, but each impact will carry more momentum for removal.
Jobs involving heavy removal, which also need a more aggressive profile, can
employ mixed shot sizes. This will allow for more efficient removal of material by
the larger shot, while imparting a profile with the smaller shot.
For particularly difficult removal jobs, such as non-skid on naval vessels, grit can
be used. The irregular, angular nature of grit will speed wear on internal
components. Generally, grit should be mixed with shot to achieve a more
aggressive removal, while trying to minimize wear to internal components.

SECTION 4.5: DUST COLLECTOR FUNCTION AND MAINTENANCE
Dust Collector Function:
The BP-10-27 shot blasting machine is equipped with an auto pulse dust
collector that helps to both separate the dust from the shot and to return clean air
back into the environment.
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
blasthead 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 and moves through eight filter cartridges. These eight
filter cartridges capture the dust particles and 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.
The dust captured by the filter cartridges is removed at regular intervals. This
dust is removed by the pulsing of the filter cartridges with a blast of compressed
air released from the header tank by means of a diaphragm valve. One of the
BP-10-27’s three blow-down tubes delivers the compressed air. The temporary
pulse of compressed air causes the dust to plummet into the dust bins located at
25

MACHINE MANUAL
MAINTENANCE

BP-10-27

the base of the filter chamber. Three filters are sequentially pulsed. The timing
of the pulsing is determined by a timer board which is located in the control box
on the front of the dust collector. The timer board is typically configured so as to
pulse a three filter section every ten seconds. The timer board acts to determine
the time between pulses and the length of each pulse. Venturi valves are
positioned above each filter cartridge to increase the effectiveness of the filter
cleaning process.
Dust Collector Maintenance:
The dust collector must be examined on a regular basis. This is because
adequate ventilation is essential for the dust collector. It is therefore essential
that the following areas are routinely examined.
•

•
•
•

•

Leaks on the blower housing assembly seal and on the dust collector
access door seal should be kept at a minimum. The dust collector access
door seal can be checked for leaks by carefully feeling for air leaks around
the seal.
Check door seal for missing or damaged sections.
The hose connections between the blast head and the dust collector must
be tight and kept in place with the use of metal clamps.
The hose must be in good condition. Flattened spots, holes, and 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, this can have a detrimental
effect on the entire system. Improper ventilation can result in inadequate
abrasive cleaning which hastens blast wheel and liner wear. It is essential that
the dust collector be well maintained. A dust collector that receives timely,
regular maintenance will result in less abrasive contamination which will help to
both reduce operating costs and increase overall effectiveness.

Fuel Recommendations

WARNING

Fuel Line

Explosive Fuel can cause fires
and severe burns.
If a gaseous odor is detected,
ventilate area and contact an
authorized service technician.

High pressure fuel line meeting a minimum of
SAE R7 standard must be installed on Kohler
Co. engines equipped with propane EFI system
(from vaporizer/regulator to injectors).
Spark Plugs

Propane is extremely flammable and is
heavier than air and tends to settle in low
areas where a spark or flame could ignite
gas. Do not start or operate this engine in
a poorly ventilated area where leaking gas
could accumulate and endanger safety of
persons in area.
To ensure personal safety, installation and
repair of propane fuel supply systems must
be performed only by qualified propane
system technicians. Improperly installed and
maintained propane equipment could cause
fuel supply system or other components to
malfunction, causing gas leaks.
Observe federal, state and local laws
governing propane fuel, storage, and
systems.

CAUTION
Electrical Shock can cause injury.
Do not touch wires while engine
is running.
