Troubleshooting
Use caution when trouble shooting a machine. Machine should have controls set to the off
position, power supply should be unplugged and/or locked out.
10.10.1 The BMG-2500 is connected to the power source but the motor will not start.
Check to
make sure that the voltage at the power source is correct as per the specification in section 2.
Check to make sure that the ground wire is secured to an assured grounding circuit with the
power source disconnected, check side of the starter box to see if the circuit breaker overload
button has been tripped. When you have checked all of these conditions and found them in order,
reconnect machine and try restarting while tilting back the machine handle just enough to relieve
pressure on the tools. This procedure should be done with caution. Do not lower the tools too
fast. Impact of the tool holders to the floor may damage the machine and/or tools.
10.10.2 The BMG-2500 makes excessive noise.
Check to make sure that you have followed proper
grease additions and maintenance as outlined in section 10.1. If this is not the problem, you could
have gear misalignment or damage to the gears.
Do not attempt to disassemble the gearbox.
Arrange for service by calling Blastrac at 1-800-256-3440.
10.10.3 The BMG-2500 will not start up after hitting emergency stop button.
The emergency stop
button is designed to stay on the off position once activated. Ensure lanyard control is in place
and the emergency stop switch has been pulled out to the on or operating position.
11.0 Operating tips
11.1 General
tips
11.1.1 Do not attempt to lift or tilt the machine over floor obstructions while the motor is running.
Serious injury to the operator and the machine could occur if not avoided.
11.1.2
The machine is supplied with a set of pocket weights that can be used in several ways. Certain
types of removal applications will not require the use of these weights. It is best to try running
without the weights to see if the machine will remove the floor material. If this doesn’t work then
add the weights to the holders. Another option would be to place the weights on the handle
sidebars, which would reduce the pressure of the machine and tools on the floor. Trial and error is
the best way of exploring the options necessary for the variety of removal requirements.
11.1.3
Every time the machine is connected to a different power source correct tool rotation must be
confirmed this is especially true for slicing applications. This is best accomplished visually by
looking at the cooling fan on top of the motor. Start the motor for a brief moment and then turn it
off.
