The 0.89mm Allen wrench is for adjustment of the cueing arm-lift mechanism.
The HTA key is keyed similarly to a T6 torx.
Make sure (as mentioned in the instructions) that the base clamp bolts are sufficiently lose to allow fore/aft “HTA” movement without binding. A 3mm ball tip Allen wrench is perfect for base clamp bolts.
