Stored Energy, Spring Tension:
Some Hawk configurations incorporate compressed springs as fail-safe mechanisms. Any work
performed with a compressed spring can result in personal injury and/or equipment damage if
the proper safety precautions are not taken. The spring must be completely decompressed prior
to beginning any work.
Stored Energy, Accumulator Pressure:
Some Hawk configurations incorporate pressurized accumulators to achieve stroking speed
requirements, to act as fail-safe mechanisms, or as part of the Safe Seat feature. During normal
operation, the accumulator will be pressurized. Failure to understand the operation of the
accumulator system may lead to personal injury and/or equipment damage due to
improper/inadvertent operation. Any work performed with a pressurized accumulator can result
in personal injury if proper precautions are not taken. The accumulator must be de-pressurized
prior to beginning any service work on the actuator.
Manual Handwheel Assembly:
When the Manual Hand Pump or Manual Handwheel Assembly is in use, be sure to use proper
Lock Out and Tag Out procedures to prevent personal injury or process interruption.
ii. Intended Use of the Hawk Actuator
Under no circumstances should the Hawk actuator be used for any purposes outside of its intended use.
Misuse of the unit can lead to harmful consequences including damage to critical components and
serious injury to the operator.
