12.4 TROUBLE - SHOOTING INSPECTION FOR NEW AND USED BINDINGS: After you have set each toe and heel piece to the correct release value setting, perform the following test: * Be sure that the ski and boot meet the visual inspection criteria described in chapter 2. IMPORTANT ! All used bindings should be cleaned before performing any inspections. Do not lubricate the gliding AFD, toe cups or heel cups. FUNCTION TEST TOE: Lateral elastic travel and return: * With the ski held firmly, hit the forefoot of the boot with your hand or a rubber mallet. Displace the toe of the boot slightly (6 - 10 mm) through the retention zone but not far enough to trigger a release. The boot should travel back quickly and smoothly to the middle point. If the toe of the boot travels far enough to activate a partial release, re - insert the boot and re - test before continuing with any further inspection. Release the boot from the binding to the left and to the right. Proceed to function test the heel. IF THE SYSTEM PASSES: * Verify the release values with the testing device. IF THE SYSTEM FAILS: * Check that the boot was not displaced far enough to trigger a release. * Check if the binding - to - boot adjustment is properly done. If not, re - adjust. * Check that the boot is centered in the heel cup. Re - insert the boot. * Check the gliding AFD for damage. Replace the toe if necessary. * Check for non - standard boot or excessive wear. Replace boot if necessary. * Check the toe for excessive wear or damage. Replace the toe if necessary. BOOT SLIDES IN TOE CUP: * Check that the forward pressure is not too low. * Check for lubricant on boot or toe cups. Clean binding and boot. TOE PIECE LOOSE: * Check for missing, stripped or loose screws. Repair or replace if necessary. FUNCTION TEST HEEL: The following test is for all step - in heels. Test for vertical elastic travel and return: * Depress the opening lever of the binding while pulling forward lightly on the upper cuff of the boot. The heel of the boot should move slightly upward (about 5 mm) through the vertical retention range of the heel. Release both hands simultaneously. The boot should return quickly to the ski, and the opening lever should return quickly to its fullest upright position. If using a test device follow the manufacturer's instructions. IF THE SYSTEM PASSES: * Verify the release values with the testing device. IF THE SYSTEM FAILS: Heel will not close or closes with difficulty: * Check for snow or dirt under the boot heel. Clean the sole if necessary. * Check length adjustment and forward pressure. Re - adjust if necessary. * Check for non - standard boot or excessive wear. Replace boot if necessary. * Check that the boot enters the binding correctly. Confirm that the boot - to - binding contact is exact. BOOT SLIDES IN HEEL SOLEHOLDER: * Check that the forward pressure is not too low. * Check for lubricant on boot or soleholder. Clean binding and boot. 86 12.4 TROUBLE - SHOOTING
