Electrical Powered Equipment
For Electric Models - Electric motors must be properly grounded at all
times. Check the outlet box to be sure the electrical service is properly
grounded. Be sure adequate power is available. Insufficient power will cause a
motor to overheat and burn out.
Use only grounded extension cords correctly sized for the current draw and voltage drop
(amp rating and length). Never use frayed, damaged, taped or under rated extension cords.
Electrical shock could result in death or serious injury to the operator
and damage to the equipment.
Check all electrical cables - be sure connections are tight and cable is continuous and in

Improper connection of the equipment-grounding conductor can result in a risk of electric
shock. Check with qualified electrician or service person if there is any doubt as to whether
the outlet is properly grounded. Adhere to all local codes and ordinances.
NOTE: In the event of a malfunction or breakdown, grounding provides a path of least
resistance for the electric current to dissipate. The motor is equipped with a grounded plug
and must be connected to an outlet that is properly installed and properly grounded. DO
NOT modify the plug provided on the motor. If the plug does not fit the outlet have a
qualified electrician install the proper receptacle.
Switch motor OFF before disconnecting power.
Do not disconnect power by pulling cord. To disconnect, grasp the plug, not the cord.
Unplug power cord at the machine when not in use and before servicing.
Starting the Engine/Motor for Electric Models
Be sure the “OFF” button is depressed on the motor starter box.
Hook up the correct voltage/phase electrical power source by plugging into the connector
provided. If the cord does not mate with the connector, consult a qualified licensed

Poisonous Exhaust
Gasoline and Propane Powered Models
DO NOT operate any gasoline/propane powered equipment without
adequate ventilation. Carbon monoxide is an invisible, odorless gas that can kill.
NEVER REFUEL A HOT ENGINE OR AN ENGINE WHILE IT IS RUNNING.
Only refuel a cool “stopped” engine in a well-ventilated area. Properly clean any spilled
fuel before starting the engine.
Gasoline is extremely flammable and poisonous. It should only be dispensed in
well ventilated areas, and with a cool engine.
Propane is extremely flammable.
Engine exhaust from this product contains chemicals known to cause cancer, birth
defects or other reproductive harm.
Small gasoline engines produce high concentrations of carbon monoxide
(CO). Gasoline or propane powered equipment should not be used in
enclosed or partially enclosed areas. Symptoms of CO poisoning include,
headache, nausea, weakness, dizziness, visual problems and loss of
consciousness. If symptoms occur get into fresh air and seek medical attention
immediately.
Gasoline Models - Consult the Engine Manufacturer’s Owner’s Manual and follow the
directions for starting the engine and allow the engine to warm up.
Propane Models - Propane models use a vapor withdrawal system. Operate the propane
engine much like you would the gasoline model. Be sure propane tank is positioned
correctly.
Turn on main fuel valve at propane tank.
Check all connections for tightness and leaks.
If you detect an odor, IMMEDIATELY shut off the main fuel valve and consult a qualified
LP-gas service person or Blastrac directly.
NEVER check for propane leaks using an open flame. Instead, use a leak-testing solution.

Operating Instructions BMP-200-X

NEVER allow propane fumes to escape in a closed area; propane is heavier than air and
will “settle.”
To start this propane powered equipment, open the main fuel valve located on the propane
tank.
Open the throttle wide open and start the engine.
NOTE: Always turn off the main fuel valve on the propane tank when equipment is not
being used.
Refer to the Engine/Motor Manufacturer’s Owner’s Manual for maintenance information
specific to the engine/motor used.

Dust Warning
Some dust created by grinding and other construction activities
contains chemicals known to cause cancer, birth defects, or other
reproductive harm.
Some examples of these chemicals are:
•Lead from lead-based paints
•Crystalline silica from concrete and other masonry products
Your risk of exposure to these chemicals varies depending on how often you do this type of
work.
To reduce your risk work in a well ventilated area, use a dust control system,
such as an industrial-style vacuum, and wear approved personal safety
equipment, such as a dust/particle respirator designed to filter out microscopic
particles.
Dry Grinding
Dry Grinding creates a large volume of airborne dust. For health reasons, the operator
should wear an applicable respirator. The dust may contain chemicals known to cause
serious illnesses, including Silicosis - a fatal disease of the lungs.
Check the chemical properties of the material to be removed and follow all EPA/OSHA
regulations.
An Industrial vacuum, capable of handling high volume of fine dust, should be used when
dry grinding with this machine. If the material being used is hazardous or contains Silica -
the vacuum unit should be capable of removing Silica and hazardous particles of less than
3 microns and if necessary, have the capability to be equipped with a HEPA filter.
Most standard drum type units use a paper bag filter. The dust created during grinding is
extremely fine and will clog the filter bag of these units and eventually damage the
vacuums motor. In addition, damage to the engine could occur.
The collected debris and filters should be disposed of according to procedures that comply
with current EPA/OSHA standards
Serious injury or death could occur if this machine is used improperly.

Maintenance
Proper belt tension must be maintained to transmit the engine/motor power to the cutting
drum. An over tensioned belt will shorten belt and bearing life.
A damaged, stretched or excessively worn belt should be replaced.
Check oil level before operation. Change engine oil and filter according to engine
manufacturers recommendations.
Engine Air Filter
Important! Clean air filter element daily
Inspect the air filter for excess dust, dirt or damage before the engine is operated. More
often if operating in an extremely dusty environment.
Operating the engine with a damaged or dirty air filter, or without an air filter, will allow
dirt to enter the engine causing premature engine wear which is not covered under the
engine manufacturer’s warranty.
Follow the engine manufacturer’s procedures for keeping filters in good condition.
Never work on or under equipment without first securing the equipment to prevent it from
moving or falling.
Always work on a flat and level surface.
Remove spark plug lead on gasoline/propane engine models or disconnect the supply
voltage connector on electric models before performing any maintenance.
Disconnect the power cord at the machine.

Operating Procedures for BMP-200-X (GAS)
Start-Up
•Add oil and gasoline to the machine.
•Move the fuel valve lever to the ON position.
•Move the choke lever to the CLOSED position (cold engine).
•Move the throttle lever 1/3 of the way toward the FAST position.
•Turn the engine switch to the ON position.
•Operate the starter by lightly pulling the starter grip until you feel resistance, then
pull briskly.
•Gently return the starter grip.
•Lower drum and begin grinding.
•Read the following additional information before operating your scarifier.
Caution: Never tilt the unit back on the handle. Oil will flow into the cylinder head
and could severely damage the motor and void the warranty.
Drive Motor/Engine:
The internal combustion engines are supplied without fuel or motor oil. Therefore, be sure
to fill them as instructed in the manufacturer’s manual. If the motor suddenly stops, the oil
could be to low or it may have been overfilled.
Caution: Start the motor ONLY when the cutter drum assembly is in the raised position
and the parking brake on.
Cutter/Drum Configuration
Check to make sure that the drum is configured with the cutters we recommend for the
application in question. When working with special milling cutters, be extra careful about
the correct direction of drum rotation and correct cutter installation. Never tip the machine
on its back to look at the cutters. This can be done quickly and easily by removing the
endplate. When putting the endplate back on the machine, make certain to check the
tightening torque of cover nuts.
Caution: To avoid bearing damage, repeat this check of the cover nuts from time to time!
Working with the Scarifier:
To engage the drum, lift the black handle up and proceed in forward motion with the lever.
Once the drum engages, you can go lower for more aggressive cutting or back up for
lighter scarifying.

Operating Instructions BMP-200-X

Caution: Do not lower the black handle too deep. This will NOT increase productivity.
When the depth is set correctly, the machine will run smoothly.
To stop scarifying, lift the black handle up and proceed in a backward motion until the
lever is in the uppermost position
Changing the cutter drum:
Always be sure to switch off the machine before removing the endplate. This will prevent
any flying debris from injuring the worker. Remove the cover nuts from the endplate, and
then remove the endplate to expose the cutter drum assembly.
Dust Control:
Should dust control be of concern, please contact Blastrac to inquire about our powerful
dust control vacuums. The BMP-200-X can be used with an optional 2” vacuum
connection.
If you need further assistance, please call our toll free number 1-800-256-3440.

Cutter and Flail Shaft Recommendations
- The above flail shafts are showing excessive wear. These shafts should have been
replaced much earlier.
To a great extent, economical use of cutter drums depends upon proper maintenance. Changing flail
shafts before they become excessively worn and begin to oval out the shaft holes can significantly
increase the life of the drum. If you run a machine with badly worn flail shafts you can easily
destroy a drum in just a few hours. These shafts are only surface hardened in order to maintain their
internal strength. This is why it is important to replace them as soon as the grooves are 1/5 of an
inch or 5mm deep.
Changing the shafts early provides the following advantages:
•The drum shaft holes will not wear as fast thus increasing drum life.
•Breakage of shafts can be avoided, thus saving a great deal of downtime refitting the
machine.
Recommendations:
•When working with five or eight point Tungsten Carbide tipped cutters or special milling
cutters, replace the shafts every fifteen to twenty hours of operation.
•When working with steel cutters change the shafts every time new cutters are installed.
•Change the entire cutter/drum assembly after 3 sets of cutters have been used up, if not
sooner.
