WARNING: WHEN SETTING UP THE MACHINE ON A VERTICAL FLANGE THE

INSTALLATION.

paragraph 4).
When running, the following symptoms indicate that the machine is out of balance:
- Uneven arm rotation (erratic movement) this must be rectified immediately
as this may cause damage to the drive system.
- The arm or balance weights make the machine race as it goes past the 12
o'clock position i.e., the tone of the motors will change.
CAUTIONS: TO PREVENT DAMAGE TO THE MACHINE IT IS ESSENTIAL THAT
IT IS ACCURATELY BALANCED.
WHEN LIFTING AND POSITIONING THE MAIN COUNTERBALANCE WEIGHT
ATTACH THE SUPPLIED LIFTING LUG TO THE THREADED HOLE IN THE
WEIGHT AND USE A MECHANICAL LIFT.
BEFORE OPERATING RECHECK THAT THE BALANCING WEIGHTS AND
PLATES ARE FULLY SECURE ON THE MACHINE.
