Powermatic 701 operating instructions Operating Handle, Gib Adjustment

Operating Handle

Referring to Figure 2:

The operating handle can be mounted on either the left- or right-hand side of the mortiser. The handle hub (D) comes mounted on the right-hand side from the factory. If right-hand operation is desired skip steps 1–3 and proceed to step 4. For left-hand operation the hub must be moved to the left side as follows:

1.Unscrew and remove the hub lock knob (A), flat washer (B), spring (C) and hub (D) from the pinion shaft (E).

2.Remove the protective sleeve from the gear shaft on the left side of the mortiser.

3.Install the hub (D), spring (C) and flat washer

(B) on the left-side pinion shaft and secure the assembly with the hub lock knob (A).

Referring to Figure 3:

4.Loosen the lock handle (F) located on the hub (H).

5.Insert the operating handle into the bracket on the hub. Position the upper part of the handle away from the mortiser allowing it to clear the switch box during operation.

Note: If handle is mounted on the right side, also position the handle so the upper portion is away from the mortiser

Note: The handle assembly is spring-loaded permitting the operating handle to be repositioned by pulling out the hub (H) and repositioning it in 36º increments (ten positions total) on the pinion shaft.

Gib Adjustment

Now that the operating handle has been installed, the gib screws that were previously loosened should be adjusted.

Alternately raise and lower the mortiser head with the operating handle, then adjust each of the three set screws (Figure 1) with a 3mm hex wrench the same number of turns.

Tighten the set screws to remove play from the column but do not over tighten such that it is difficult to raise and lower the operating handle.

When adjustment is complete, tighten the lock nut with a 10mm wrench while maintaining the position of the setscrew with the 3 mm hex wrench.
