MANUAL LOCK
Manual Lock Overview
The Espire features a mechanical locking mechanism that can be locked or
unlocked while under load, with a maximum holding limit of 25lbs/11kg.
The manual lock cable is attached to the upper elbow assembly, near the
midline. The lock can be engaged every 10 degrees (13 positions). A strain-
relief is included to reduce the likeliness of damage due to excessive pull on
the lock cable. The lock cable may or may not be attached to your harness.
Pull on the lock cable to engage/
disengage the lock. Lock response
will vary by the amount of force
applied.
Standard Lock-Unlock
A strong cable pull (clicking sound) disengages or
re-engages the lock.
Temporary Unlock
A light cable pull (no click) unlocks the elbow joint
temporarily. Releasing the cable tension re-engages the
lock.
Note: When unlocking the elbow, the weight on the elbow may have to be
temporarily removed in order for the lock to disengage.
THE COUNTERBALANCE / SPRING-ASSIST
Counterbalance and Spring-assist Overview
Depending on which model you are using, the Espire will include either a
counterbalance or spring-assist mechanism:
Espire Model
Lift Compensation Aid
Classic Plus, Classic
Counterbalance
Basic
Spring-assist
Both the counterbalance and spring-assist aid in flexion and extension of
the Espire Elbow. Different amounts of tension are necessary based on the
elbow’s overall length, the weight of the terminal device, and the type of
clothing worn.
Adjustment Dial Location
The adjustment dial may be located on either the inside or outside of your
elbow. Refer to the arrows on the dial to perform your adjustments. The dial
looks identical for both counterbalance and spring-assist; however, these
mechanisms adjust in opposite directions (see next page).
Note: Adjustments are easier to make when the forearm is flexed.
Caution: Be aware that if the adjustment dial is at maximum tension and
the arm is raised to a horizontal level, the elbow could suddenly flex.
Caution: To prevent injury, users should ensure the elbow is in the
maximum flexed position when donning or doffing.
