GENERAL SAFETY INSTRUCTIONS
• Read and understand the information in this section and in this manual
completely before installing, operating or maintaining this equipment.
Failure to follow this instruction could result in severe injury or death.
• Disconnect and lock out power before installation and maintenance.
Working on or near energized equipment can result in severe injury.
• Do not operate equipment without guards in place. Exposed
equipment can result in severe injury or death.

INTRODUCTION
This manual applies to standard Type A10 free end float Falk Disc
Couplings. Couplings with spacers up to 24" can operate in either the
horizontal or vertical position without modification. Falk Disc Couplings
provide limited end float, without mechanical stops, for most applications
where a limited end float is required. For floating shaft or restricted limited
end float applications, refer to the Factory.
WARNING! Consult applicable local and national safety codes for
proper guarding of rotating members. Observe all safety rules when
installing or servicing couplings. Lockout starting switch of prime mover
and remove all external loads from drive before installing or servicing
couplings.
Maximize Performance & Life
The performance and life of couplings depend largely upon how you
install and maintain them. Before installing couplings, make certain
that foundations of equipment to be connected meet manufacturers'
requirements. Check for soft foot. The use of stainless steel shims is
recommended. Measuring misalignment and positioning equipment
within alignment tolerances is simplified with an alignment computer.
These calculations can also be done graphically or mathematically.
It is recommended that final alignment be checked using either an
alignment computer or graphical analysis. Both methods allow the
incorporation of "cold offsets" , which will compensate for shaft position
changes due to thermal growth.

Indicates a hazard which, if not avoided, could result
in minor or moderate personal injury.
Indicates information considered important, but not hazard-
related (e.g. messages relating to property damage).
• Perform periodic inspections. Equipment may fail prematurely and
could become unsafe if not properly inspected and maintained.
Failure to follow this instruction could result in mild or moderate
personal injury.
Balanced Couplings
Balanced couplings are match marked and
must be assembled with mating match
marks aligned. Dynamically balanced
couplings have the runout etched at 90°
intervals around the flange O.D. Recheck
runouts after coupling is mounted. Any
wide variation in these readings must
be corrected. Some possible causes of
variation are burrs on mating components
or bent shafts.
ANNUAL MAINTENANCE
For extreme or unusual operating conditions, check coupling more
frequently.
1. Check alignment per Step 5, Page 3. If operation limits from Table 1,
Page 3 are exceeded, re-align coupling to installation limits.
2. Check outer blades of discpacks near bushings for fatigue cracks.
Discpacks can be checked while coupling is in operation by using a
strobe light. Replace cracked discpacks and recheck alignment.
A slight bowing or "S" like distortion is normal.
3. Check tightening torques of all drive bolts.
GENERAL ASSEMBLY INFORMATION
Standard mechanics tools, torque wrenches, a straight edge and feeler
gauges or dial indicators and brackets and micrometers are required to
install Falk Disc Couplings. For best results use a dial indicator to check
final alignment and make certain bolts are tightened to the required
elongation or torque listed in Table 1, Page 3. The drive bolts have been
factory tightened to the required elongation indicated in Table 1 and
should not be disturbed. Outside micrometer sizes required to measure
drive bolt elongation are listed in Table 1, Page 3.
