Page 4: Description
MACHINE DESCRIPTION The A95 shot blaster is designed to shot blast concrete surfaces and either remove material from the concrete surface or texture the concrete sur- face so material can adhere to the concrete—these steps can sometimes happen concurrently. Removing mastic or epoxy may plug the machine. -

Read the manual carefully to learn equipment applications and limitations, as well as potential hazards associated with this type of equipment. -
Page 8: Shot Blaster Safety Guidelines
Safety SHOT BLASTER SAFETY GUIDELINES Before use, anyone operating this equipment must read and understand these safety instructions. Dust Collection Shot Blasting Turn off machine before working with dust collector. Beware of hidden obtrusions. Watch out for hidden dangers and protrusions in flooring. Do not Do not switch off or remove the dust collector while the machine is use on largely uneven surfaces. -
Page 9: Electrical Practices
Safety ELECTRICAL PRACTICES WARNING: ELECTRICAL CORDS CAN BE HAZARDOUS. MISUSE CAN RESULT IN FIRE OR DEATH BY ELECTRICAL SHOCK. READ CAREFULLY AND FOLLOW ALL DIRECTIONS. CAUTION: ALWAYS FOLLOW APPLICABLE ELECTRICAL CODES, STANDARDS AND/OR REGULATIONS. CONSULT YOUR LOCAL ELECTRICAL AUTHORITY OR A LICENSED ELECTRICIAN BEFORE ATTEMPTING TO MODIFY AN ELECTRICAL INSTALLATION. ENSURE THAT CIRCUIT AND GROUND FAULT PROTECTION DEVICES AND ALL OTHER ELECTRICAL SAFETY EQUIPMENT ARE FUNCTIONING PROPERLY. - Page 10 Safety ELECTRICAL PRACTICES (CONT’D) How to Use This Table Determine your supply voltage. Determine the total length of your cord including all extension cords. Determine the maximum amp draw for your machine. Trace your voltage across the top of the table to the first length that is greater than or equal to your cord length. Follow the column down to the first row that contains a maximum amp draw greater than or equal to yours.

Components and Assembly HANDLE ASSEMBLY (FIGURES 1-2) CAUTION: THE HANDLE IS ONLY FIXED WITH TWO PULL-OUT PINS AND CANNOT BE USED AS A LIFTING POINT FOR HOISTING. The machine comes with the handle disassembled. To assemble the handle: Insert handle into handle frame and align holes to the desired position keeping the motor cable behind the handle. Insert the two pull-out pins. -
Page 12: Operating Controls
Components and Assembly OPERATING CONTROLS (FIGURE 3) FIG. 3 [1] Blast Wheel Start/Stop Buttons Pushing the START button starts the blast wheel motor, pushing the STOP button stops the motor. [2] Emergency Stop Switch In case of an emergency push the emergency stop switch to immediately stop the blast wheel motor. To release the emergency stop switch, twist the red button and pull it upwards. -
Page 13: Separator
Components and Assembly SEPARATOR (FIGURE 4) The separator (1) is mounted inside the cover (2). The dust collector is connected to the hose connector (3) and generates the appropriate airflow within the separator to separate the dust from the shot. The dust flows to the dust collector, while the shot passes through the removable mesh tray (4) and drops back into the hopper (5). -
Page 14: Blast Wheel Drive
Components and Assembly BLAST WHEEL DRIVE (FIGURE 7) The blast wheel (1) throws shot at the surface to be treated. It is surrounded by replaceable liners (2) and is driven by an electric motor (3) via the wheel hub (4). Shot is fed to the blast wheel through the feed spout. The position of the control cage (5) determines the direction shot is thrown to the surface and the evenness of the blast pattern. -
Page 15: Shot Selection
Components and Assembly SHOT SELECTION Selection of shot is important, as this is the material that profiles the surface. The use of incorrect shot increases wear on the machine. Contact NFE customer service regarding the best shot to use for your application. S280 Shot (Approx. -
Page 16: Manually Moving The Machine
Components and Assembly MANUALLY MOVING THE MACHINE (FIGURE 10) CAUTION: WHEN MOVING MACHINE, DO NOT DROP ON REAR WHEELS AS THIS COULD CAUSE THEM TO GO OUT OF ADJUST- MENT. When manually moving the machine around the jobsite, keep the machine tilted back so the front caster is about 4-8” (10-20 mm) off the floor. Moving the machine using the rear wheels helps to keep the magnets from picking up debris. -
Page 17: Operation
Operation WARNING: BEFORE PERFORMING MAINTENANCE, ALWAYS DISCONNECT THE MACHINE FROM POWER TO PREVENT ACCIDENTAL START-UP. CLEANING DEBRIS FROM HOPPER (FIGURE 11) WARNING: USE GLOVES WHEN REMOVING DEBRIS FROM HOPPER. STAPLES, NAILS OR OTHER SHARP OBJECTS THAT MAY HAVE BEEN PICKED UP DURING USE COULD CAUSE INJURY TO BARE HANDS. Release the clamps (1), then open the cover (2). -
Page 18: Preparing For Operation
Operation PREPARING FOR OPERATION Complete the following before start-up: • Ensure all protective covers are attached correctly. • Check that all parts are assembled correctly. • Check that all fasteners are tight. • Check parts for damage and wear; replace if necessary. •... -
Page 19: Start-Up Procedure
Operation START-UP PROCEDURE (FIGURE 12-13) WARNING: DO NOT TILT BACK THE MACHINE WHILE BLASTING. TILTING MACHINE WILL CAUSE SHOT TO SPRAY OUT AND COULD CAUSE INJURY. CAUTION: WHEN BLASTING CONCRETE OR ASPHALT, ONLY OPEN THE SHOT VALVE WHEN THE MACHINE IS MOVING. IF THE MACHINE IS NOT MOVING AND THE VALVE IS OPENED, DEEP HOLES WILL BE BLASTED INTO THE SURFACE WITHIN SECONDS. -

Page 22: Working Direction
Operation WORKING DIRECTION (FIGURE 18) CAUTION: TAKE CARE NOT TO TRIP OVER THE POWER CORD AND DUST HOSE. CAUTION: CLOSE THE SHOT VALVE BEFORE TURNING THE MACHINE AROUND TO MAINTAIN AN EVEN BLAST PATTERN AND AVOID DAMAGING THE FLOOR. Carry out blasting in parallel back-and-forth tracks working away from the dust collector. Make sure the power cord and dust hose do not become twisted. -
Page 23: Turning Off The Machine
Operation TURNNG OFF THE MACHINE (FIGURE 19) WARNING: USE A MAGNETIC SWEEP IMMEDIATELY AFTER BLASTING. STEEL SHOT THAT IS LEFT ON THE WALKING SURFACES CREATES A SLIPPING HAZARD WHICH COULD CAUSE UNEXPECTED FALLS. Close the shot valve by moving the shot control lever (1) to the closed position. Continue pushing the machine forward until the shot valve is closed to prevent holes from being blasted into the floor. -
