• Make sure maintenance schedule has been followed before operating machine.
• Only trained personnel may maintain and operate the machine.
• Operate controls smoothly without jerking. If cutting unit stalls, back off cutter from
work face. Do not overload cutter bits. Machine can be damaged.
• Cutting conditions are best if cutting heads move toward the carrier vehicle. If unit
moves sideways to achieve a larger cutting area, ensure pressure on excavator’s
boom, arm and cutting head bearing is not excessive.
• Periodically check cutting unit is clear of debris. This can affect cutting rate.
• Ensure cutting unit or any part of unit is correctly attached during any
maintenance
work.
• Do not operate cutting unit at end of excavator hydraulic cylinder stroke.
• Do not use cutting head with damaged or missing bits. Vibration will damage unit
or
excavator.
• Do not run cutter head in reverse.
• Do not cut while tracking excavator. This may damage unit.
• Do not place cutting unit against working surface before starting. This may damage
unit. Unit should be running and fed into working surface at a rate that does not
allow
stalling.
