Taking Side Motion OUT of OVER-ARM

DISCONNECT MACHINE FROM POWER

SOURCE.

1.Loosen hex nuts (A) and gib adjusting screws (B) and (C) Fig. 31.

2.Loosen nuts (D) Fig. 31, and adjust bolts (E), so that base wraps around column securely. If column is tight in base, turn bolts (E) clockwise to loosen. IMPORTANT: Turning bolts (E) clockwise will open the base jaws, while turning bolts (E) counter- clockwise and tightening nuts (D) will close the base jaws. Check elevation by turning crank handle, making sure the column moves up and down without binding.

3.	Tighten screws (B) Fig. 31, against the column gib	Fig. 31
	until all side motion disappears in over-arm.
4.	Securely lock hex nuts (A) while holding screws (B)
	and tighten screw (C).

TIGHTENING YOKE AGAINST BEARING CARRIAGE

DISCONNECT MACHINE FROM POWER

SOURCE.

After extended use "play" may develop between yoke

(C) Fig. 32, and bearing carriage (B). To reduce "play":

1.Remove guard and saw blade.

2.Remove end plate and cross cut stop from track- arm.

3.Remove yoke assembly from track-arm and place yoke assembly (C) Fig. 32 on saw table.

4.Pull yoke clamp handle (A) to the position shown in Fig. 32 to loosen, and loosen set screw (D) one turn only.

5.Turn nut (E) Fig. 32 clockwise until "play" between the yoke (C) and bearing carriage (B) is removed. Then tighten set screw (D),Fig. 32

6.Tighten yoke clamp handle (A) Fig. 32 by moving it forward, and reassemble yoke (C) assembly to track-arm.

ADJUSTING BALL BEARINGS AGAINST TRACK RODS

The carriage is mounted on four double row, sealed ball bearings, two on fixed shafts. To adjust the ball bearings against the track rods:

DISCONNECT MACHINE FROM POWER SOURCE.

1.Remove end plate from track-arm, loosen clamp knob (A) Fig. 33, and move cuttinghead (B) to the front of the track-arm, then tighten clamp knob (A).

2.Loosen two set screws, one of which is shown at (C) Fig. 33, that lock both front and rear bearing eccentric shafts. The other screw is at the rear of the carriage.

3.Rotate yoke (B) Fig. 33 until hole in yoke is under either eccentric shaft (D).

4.Place roller head wrench (E) over hex nut (G) that locks shaft (D) Fig. 33, and loosen hex nut. Repeat this procedure at rear bearing.

5.Insert hex wrench (F) into eccentric shaft (Fig. 33), and turn until all "play" is removed between bearing (D) and track rods. Repeat this procedure for the rear bearing.

6.Tighten hex nuts with wrench (E) and lock set screws (C) with wrench at both bearings (Fig. 33). Replace end cap on track-arm.
