can be referenced from the centre of the elbow. A removable sticker is applied to the forearm to reference the maximum cut area.

4.2 Protective Foam Insert
(Classic Plus)
A foam insert is installed prior to shipping to protect the output
wires and to prevent dust or debris from entering the elbow.
Note: Foam insert must be in place prior to cutting the
forearm and completing wrist fabrication. Failure to use
the insert will damage the Espire Elbow.
4.3 Cutting the Forearm to Length
1. Measure the desired length of the forearm.
2. Cut the forearm, preferably with a bandsaw.
3. Continue with wrist fabrication.
Note: It is important to avoid subjecting the system to
excessive vibration such as that caused by a carbide-tip
saw blade or a sanding belt/disk.
