Pump; Electronics - Strong Floor-Mate 80E Owner's Manual

B. Pump
1. When removing a section of hose, pressure must be relieved before undoing a fitting.
This can be done by putting the pump in reverse and running it slowly until the
discharge hose at the pump becomes soft. Failure to do this will result in the hose
being under pressure when the fitting is undone, and material being blown out when
disconnected, striking the face and eyes with the danger of injury or blindness. Also,
the hose could whip about and cause an injury.
2. When pumping in reverse, be sure that material is flowing back into the hopper as
evidenced by the materials level in the hopper rising. Watch the discharge hose to
avoid collapsing it and causing the pump to run dry.
3. NEVER RUN THE MATERIALS PUMP DRY because just a few minutes of
running dry will ruin the pump stator. Always have water or slurry in hopper when
running pump.
C. Electronics
1. Read all instructions and safety literature for electrical components prior to connecting
power.
2. Only a qualified electrician should be allowed to perform and service the electrical system on
this machine.
3. Never remove any covers from the electrical components without first isolating and locking-
out the source electricity to the machine.
4. While the machine is not in use and/or at the end of each day, the machine's red disconnect
knob should be turned to the off position and locked.
5. Before unlocking the red disconnect knob or reconnecting power to the machine, always
check to make sure that the pump and the mixer control switches are in off position and all
guards are in place.
