5. Operations
5.1 Operations of AH-3T (for Sliding Tables)
AH-3T is primarily intended for holding down a workpiece on the sliding

Set Assembly upward along the lead screw (as shown in Fig. 4a).
2. Choose a suitable side for installing the T-slot Locking Block (F)
and insert the T-slot Locking Block F into the T-slot on the sliding table
(as shown in Fig. 4a).
For ST-1500 Sliding Table, Cross Section 2 of the T-slot
Locking Block should be used.

2. Loosen the two set screws on the
Stop Block (E) and set distance (L)
between the Stop Block (E) and the
bottom of the arch hold down as
shown in Fig. 5.
The distance of (L) = (t) + 2-3/16"
3. Once the position of Stop Block (E)
is determined and set, then secure
the set screws tightly.
