SECTION I
GENERAL DESCRIPTION
BMS-H2750
The BMS-H2750 is operated by a propane-powered engine, driving a
tandem hydrostatic pump system, creating a (skid-steer) zero turn radius drive
train. Surface covering and coatings are removed by lowering a weighted blade
onto the surface and moving forward under a high torque drive system. The
surface coating is removed by a flexible sharpened blade conforming to the
floor surface, with the weight of the machine holding the blade firmly to the
floor. The weight does not allow the blade to lift or ride over well-adhered
surface coating material, thus lifting the off the floor coating.
After layers of carpet or laminates are removed the machine can be
connected to a grinder or slicer attachment to either clean up adhesives or
remove stubborn coatings.

SECTION III
SAFETY AND PRECAUTIONS
Before operating the BMS-H2750 please read the entire operation and safety manual with
complete understanding of the safety section. If you have any questions on safety and precautions
please call 1-800-256-3440.
There are several advantages to an effective safety program which include: lower operating costs,
lower workman compensations, less work time lost, high employee morale, and less problems. No
one can work safely without knowing what precautions to take to insure personal safety.
Operators must know what equipment to wear, which job practices are safe and which are not, and
must be aware of what hazards are possible in the work area. A regular schedule of Preventive
Maintenance on your equipment is the best protection against unpleasant surprises that slow
production and sometimes result in injuries. Here are a few suggested safety tips.
1. The first step before any maintenance or inspection takes place should be to stop
the engine and disconnect the battery terminals.
2. Wear proper eye and ear protection and heavy duty work gloves at all times.
3. Practice good Preventive Maintenance.
4. Practice good housekeeping.
5. Allow the BMS-H2750 to come to a complete stop, turn off engine, and chock rear
wheels before performing any maintenance procedures.
6. Replace worn parts when necessary.
7. Do not reach into blade or control arm areas while machine is in operation.
8. Do not attempt to open any access door until the machine has come to a complete stop and
the engine and propane is turned off.
9. Be sure all electrical inspections or changes are done by a qualified electrician.
10. Loose surface coating can cause dangerous footing. Always be alert and careful.
11. After replacing parts be sure all tools used are removed from the machine. Be sure all bolts
and nuts are tightened. The loose connection of a rotating part could cause the part to fly
off with explosive force, causing serious damage to the equipment and possible injury to
the operator.
12. Always lower blade to the ground when the machine is unoccupied by the operator.
Serious bodily injury may result if arms are not in the lowered position when not occupied.
13. Never allow unauthorized personnel or the general public into the work area.
14. The work area should be barricaded off to adequately keep all untrained persons out of the
work site. If an unauthorized person enters the work area, stop the machine immediately
and do not restart the machinery until they have left the work area.
15. Always allow a 200-foot buffer safety zone around all surface preparation activity.
16. Always run the BMS-H2750 in a well-ventilated area, with an approved OSHA air-
monitoring system in place at all times.
17. Read and obey all safety labels placed on the machinery at all times. If safety labels have
been destroyed or removed call 1-800-256-3440 for replacement labels prior to operating
the machinery.

7
18. The BMS-H2750 is not a toy. All operators must be over 18 years of age and must have
read and reviewed the safety and procedures manual before operating the machinery.
19. The BMS-H2750 is designed for surface preparation ONLY. It is not intended for towing,
pushing or any other procedure not described in this manual.
20. Propane systems should be checked and documented twice yearly by a certified propane
professional for leaks or damaged parts. If a propane leak is detected leave the machine
immediately and seek assistance from propane professional. Do not use or restart
machinery until it is determined safe.
21. Horseplay and or high speed cornering is not allowed with this machine and could cause
rollover resulting in injury or death.
22. No smoking or open flame is allowed while machinery is running or within 50 feet of the
machine.
23. Operator must be sober and not under the influence of drugs or medication and under full
control of all bodily senses while operating this or any machinery.
24. When transporting the BMS-H2750, it is recommended to use a low bed tilt trailer. This
procedure insures the wheels do not leave a stable surface.
25. All BMS-H2750 operators must receive safety training before performing any functions
with the machine. Blastrac offers a maintenance orientation. New owners and operators are
advised to call 1-800-256-3440 for an appointment.

START-UP AND BREAK-IN
The BMS-H2750 has been safety tested and run at our factory prior to shipping. All fluid levels
have been topped off; however, no propane has been added to the tanks for safety shipment
purposes. Before running the BMS-H2750 please check the following items that may have shifted
or changed during shipping.
1. Raise engine covers and check oil level.
2. Check air cleaner filter element for snug fit.
3. All battery cable connections are snug.
4. Inspect for major hydraulic oil leaks. Snug hydraulic fittings using two wrenches. Use
caution not to over tighten.
5. Fill propane tank.
6. Mount propane bottle in brackets, be sure bracket alignment pin corresponds with
alignment slot on bottle.
7. Attach propane hose to liquid side of bottle by attaching to the handle valve. Snug fit the
female connector attached to hose and slowly turn valve on. You should hear gas briefly
enter the propane hose. Immediately check for propane leaks with soapy water solution. If
leak persists after retightening the knurled female connector: STOP, turn off the bottle at
valve and seek assistance from certified propane professional. Serious damage and or an
explosion could occur.
8. Check lug bolts for tightness, torque 85-100 lbs.
9. Return all engine guards to proper position.
10. You are now ready to start the engine.
11. Crank the engine by turning the key in the on position. The engine will crank for 3 to 5
seconds while the propane enter the carburetor. If the engine does not start, turn the key
off, wait 1 minute and try again. If again unsuccessful, check propane valve to be sure it is
open. If still unsuccessful turn off propane valve and seek assistance or call 1-800-256-
3440.
12. Once the engine is warming and running, and the operator is safely in the seat, the machine
can be driven.
Please turn to Section VI for Machinery Operation.
NEW MACHINE BREAK-IN
Since the BMS-H2750 is a very low maintenance and user-friendly machine, the only break-in is
for the Kohler engine. Please refer to the owners manual, included is the manual and the
maintenance schedule found inside the air cleaner plastic cover supplied
by Kohler.

SECTION VI
MACHINERY OPERATION
Before reading the machinery operation section, new operators should familiarize themselves with
the 3 diagrams depicting the TOP, LEFT, and RIGHT views of machine. These drawings show the
activation of all moving parts of the BMS-H2750.
1. To move the machine: Using the right hand, slowly move the shifter lever in the
desired direction. Forward and left moves the machine to the left, backward and
Right reverses the machine to the right. It is just that simple to drive. Speed is
controlled by amount of movement on the joy stick and also by moving travel
Speed lever.
2. The left joystick lever is used to position the blade to the surface. Moving the lever forward
and backward moves the blade up and down. Left and right movement changes the
blade pitch.
3. Throttle control is on the left side of the seat, taking the unit from idle to 3400
RPM. The most optimum speed is 2600 to 3200 RPM. To change RPM of engine turn
throttle knob clockwise to lower RPM and counterclockwise to raise RPM.
It may be necessary to choke engine to start it.
4. A cooling fan will run behind the seat when engine is running to keep hydraulic
oil cool.
5. Hydraulic reservoir is accessed by tilting seat forward.
6. To change scraping blades: Stop engine. Loosen the set bolt at the rear of the
Blade holder block using a ¾” open-end wrench. Slide the dull blade out and
Insert a new blade up against the shim stop. Retighten the set bolt and raise the control
arms to remove wooden block. Lower control arms and resume scraping.
The large 1-1’8” blade holder bolt should not need to be more that hand tight.
With a little practice you should be able to change blades in 15 seconds. Dull
blades can be resharpened and reused many times.
SEE DRAWING OF BLADE CHANGE PROCEDURE
1 Operators should lower the blade by pressing the left hand lever forward each
time they get off the machine. This safety practice eliminates possible bodily
injury from lowering the blade by unauthorized operators.
2 The transport caster should not be in contact with the floor while scraping. It will
lift off the floor when blade is lowered. Caster contact with the floor while

14
scraping will negatively affect scraper productivity and steering.
3. Do not transport machine with front of machine off the surface of floor higher than 1/2" or
irreparable damage to lift cylinders will result.
