Avoid contact with “live” terminals and prevent contaminant entry. Replace the terminal box
cover as soon as connections are complete.
Chapter 8: OPERATIONAL TEST – Warnings and Cautions
Always perform an operational test of the brake after any replacement, adjustment, or repair.
Read and understand the intent of the warnings published in this document – if in doubt, ask.
In a hoist application, post observers to monitor the position of the hook if it travels out of sight of
the operator.
Before conducting an operational test, remove all tools, chocks and other equipment, which may
create a hazard when the machine is operated.
Following any repair or adjustment, and before conducting an operational test, verify that all brake
adjustments are complete in accordance with Chapter 6.
Before attempting to operate any motion in any application, advise and account for the location
and security of all personnel involved.
Chapter 9: MAINTENANCE AND REPAIR – Warnings and Cautions
When replacing a brake wheel or associated drive line components on an existing installation,
verify that the brake is centered with uniform lining contact as described under the topic “Brake
Installation”. Incorrect repair or replacement can result in death or injury to personnel.
During operation, the actuator’s internal temperature and pressure will increase. This is normal
but presents a risk of burns and scalds if the filler plug is removed while the actuator is hot.
Switch off power to the actuator and allow it to cool to ambient temperature before checking,
topping off, or draining hydraulic fluid.
Improper brake operation and loss of load control due to incorrect brake adjustment can result in
death or injury to personnel. Under no circumstances is it permissible to allow the brake release
lever to bottom out against the hydraulic actuator.
