ADJUSTING CUTTINGHEAD BALL BEARINGS AGAINST TRACK RODS
The carriage is mounted on four
The ball bearings must ride smoothly and evenly against the track rods to do accurate work. If wear should ever develop in the track rods causing “play” between the ball bearings and the track rods, the ball bearings can be adjusted as follows:
1.DISCONNECT TOOL FROM POWER SOURCE.
2.Move the cuttinghead to the center of the track, and check to see if any play is present.
3.To adjust, place special wrench socket (A) Fig. 39, supplied with the saw, over hexagon nut, located under- neath the carriage. Place one of the wrenches (B) supplied, on flats on special wrench socket (A) and loosen hexagon nut.
4.Loosen set screw (C) Fig. 39, with allen wrench to release locking action on eccentric shaft.
5.Using a small screwdriver (D) Fig. 40, turn screw slightly until all play is removed.
6.Lock set screw (C) Fig. 39, and tighten hex jam nut with special socket wrench (A).
7.Use the same procedure to adjust rear bearing.

ADJUSTING TRACK RODS
After a period of heavy use the two track rods (A) Fig. 41, may in time show signs of wear especially where the cuttinghead is used most often in the track arm. If this happens you will have an uneven bearing surface for the cuttinghead bearings.
If an adjustment should ever become necessary proceed as follows:
1.DISCONNECT TOOL FROM POWER SOURCE.
2.Remove rear plate from track arm (B) Fig. 41.
3.Remove the cuttinghead assembly (C) Fig. 41, from the track arm (B).
4.Remove four screws (D) Fig. 41, one of which is shown, and rotate track rods (A) 180 degrees.
5.Replace track rods (A) Fig. 41, inside track arm (B) and fasten with four screws (D).
6.Replace the cuttinghead assembly.
7.Replace rear plate on track arm.
