When using Lovejoy products, you must follow these instructions and take the following precautions. Failure
to do so may cause the power transmission product to break and parts to be thrown with sufficient force to
cause severe injury or death.
Refer to this Lovejoy Catalog for proper selection, sizing, horsepower, torque range, and speed range
of power transmission products, including elastomeric elements for couplings. Follow the installation
instructions included with the product, and in the individual product catalogs for proper installation of power
transmission products. Do not exceed catalog ratings.
During start up and operation of power transmission product, avoid sudden shock loads. Coupling assembly
should operate quietly and smoothly. If coupling assembly vibrates or makes beating sound, shut down
immediately, and recheck alignment. Shortly after initial operation and periodically thereafter, where
applicable, inspect coupling assembly for: alignment, wear of elastomeric element, bolt torques, and flexing
elements for signs of fatigue. Do not operate coupling assembly if alignment is improper, or where applicable,
if elastomeric element is damaged, or worn to less than 75% of its original thickness.
Do not use any of these power transmission products for elevators, man lifts, or other devices that carry
people. If the power transmission product fails, the lift device could fall resulting in severe injury or death.
For all power transmission products, you must install suitable guards in accordance with OSHA and
American Society of Mechanical Engineers Standards. Do not start power transmission product before
suitable guards are in place. Failure to properly guard these products may result in severe injury or death
from personnel contacting moving parts or from parts being thrown from assembly in the event the power

transmission product fails.
