TECHNICAL MANUAL - Tyrolia

5. Heel height and wear: Check this boot standard with
the same procedure used for the toe. The heel posts
(A 3) + (C 3) are located at the rear of the device
(see pict 64).
6. The marks “A/C” help to select a “Child” boot from an
“Adult” by indicating the standardized sole width.

NOTE:
Any boot which passes points 3, 4 and 5, as well as
conforming to the Visual Inspection Checklist, may be
accepted for use with TYROLIA bindings.
Boots which fail any point should be repaired or replaced.
These checks apply only to boots used with TYROLIA
bindings. Consult other binding manufacturers for their
used boot specifications.

CLEAN VS. LUBRICATED SKI BOOT TEST
This test is designed to determine the influence of a given
boot on the release characteristic of a binding. It should
be performed on boots not meeting all the points of the
HEAD/TYROLIA boot visual inspection criteria, or if measured
release values fall outside the system “inspection”
tolerance. It is seen as the “last chance” for a boot to
qualify before getting eliminated from inventory.
1. Clean the boot(s) to be tested with soap and water.
Allow to dry.
2. Select an appropriate HEAD/TYROLIA “reference”
binding that has displayed release values within the
inspection tolerance on the TYROLIA Adjustment Chart.
Clean the binding’s boot contact surfaces with soap
and water and allow to dry.
3. Test the binding and boot in Twist and Forward Lean
at a mid-scale indicator value (Only one direction of
twist is required).
4. In a further test run lubricate all boot/binding contact
areas with soapy water. Retest in Twist and Forward
Lean.
5. Results of each lubricated test should be within 20%
of the corresponding results when tested clean. Any
boot which fails this test should not be used with a
HEAD/TYROLIA binding.
