Installation

4.4 Checking the Air Gap

The air gap (X) between magnet and armature should be between 0.9 and 1.0 mm. Using
a feeler gauge between the armature and magnet, verify the air gap is within the
acceptable values.
Take measurements at various points around the brake's circumference to ensure the air
gap is equal throughout the entire brake circumference.
If the air gap is not within tolerance, tighten or loosen the lock-nuts or bolts to expand or
contract the air gap as appropriate.
Ensure the air gap is equal throughout the entire brake circumference after adjusting the
air gap.
After checking the air gap, re-install the dust protection ring (1) over the lead wire cable,
ensuring the ring fits into the groves in the brake to ensure a tight seal.
