Elevating column tension is preset at the factory. It can be adjusted to remove any “play” which may develop after extended use. Adjustments can be made as follows:

1.DISCONNECT MACHINE FROM POWER SOURCE.

2.Loosen hex nuts (A) Fig. 65, and gib adjustment screws (C).

3.Adjustment to column base (B) Fig. 65, is made by loosening hex nuts (D) and turning screws (E) until column base wraps around column securely and can be raised or lowered without binding. Then tighten hex nuts (D) against column base.

4.After all movement between column base (B) Fig. 65, and elevating column (F) is removed, tighten gib and adjustment screws (C) against gib (H) until all side-to- side play is removed. Then tighten hex nuts (A) against column base. NOTE: After adjusting column tension, refer to “ADJUSTING SAW BLADE TRAVEL SQUARE WITH FENCE” to determine if saw blade travel was affected.
