trouble shooting

TROUBLE SHOOTING

Even though the finest materials and precision workman-

ship have been incorporated into your Craftsman saw, it is

reasonable to expect some wear after long periods Gf use.

Adjustment facilities have been built into the saw to

compensate for this wear. Looseness due to wear, rough

handling, or improper adjustments will usually be indicated

by reduced accuracy or the inability of the saw to perform

as intended. The usual operating troubles are listed in the

following paragraphs, with the necessary corrections

described and illustrated.

1. LOOSENESS OF COLUMN TUBE IN COLUMN SUP-

PORT - ELEVATION CRANK OPERATES ROUGH-

LY, OR CHATTERS WHEN ROTATED

When this condition exists, square crosscuts are likely to

be difficult to make, and repeated cuts inaccurate.

Adjust the column tube key as follows:

a. Checking for Looseness of Column Tube in Column

Support (Figure 43).

ARM

Figure 43

(1) Tighten the arm-latch handle

(2) Grasp the arm-latch handle with one hand and

hold a finger of the other hand at the parting line

between the column tube and column support.

(3) Apply gentle side force to the radial art]] in

opposing directions. Any !ooseness bet_Jeen

column and column support (indicated by arrow

in figure 43) can be felt with finger.

(4) If looseness can be felt, perform the following

Jperations:

NOTE: Before attempting to adjust the

column tube key, the function of this adjust-

ment should be understood. Figure 44 shows a

sectional view through the column tube sup-

port (looking downward} at the column tube

key location By loosening the left-hand set-

screw and tightening the right-hand setscrew

the column tube key will be forced tighter into

the column tube keyway. Conversely, loosen-

ing the right-hand setscrew and tightening the

left-hand setscrew wilt retract the column key

out of the column tube keyway. The setscrew

in the outer end of the column tube key must

be loosened while adjustment is being made,

and tightened with medium firmness after the

adjustment has been completed. This screw

applies pressure on the nylon friction plug, and

provides smoother elevation movement of the

column tube ... and should be tightened to

provide maximum smoothness of operation.

References to right- and left-hand positions are

as indicated in the illustration.

(1) Loosen the setscrew located in the center of the

(2) Loosen the left-hand setscrew 1/4 turn.

(3) Tighten the right-hand setscrew.

(4) Tighten the left-hand setscrew.

(5) Rotate the elevation crank to raise and lower the

radial arm. If too tight, loosen the right-hand

setscrew slightly, and check again for smooth

operation. When correct, tighten the left-hand

setscrew.

(6) Tighten the setscrew located in the center of the

column tube key until smoothest operation is

obtained.

2. BLADE DOES NOT MAKE SQUARE CUTS, AND

ACCURATE REPEAT CUTS CANNOT BE MADE

If this condition exists the trouble might be due to any

one, or a combination of, the following conditions:

a. Looseness Between Column Tube and Column Sup-

port.

Adjust as described in preceding paragraph "1", a

and b.

b. Crosscut Travel Not Properly Adjusted.

Refer to "ALIGNMENT INSTRUCTIONS", step "4.

Squaring the Crosscut Travel", preceding. If crosscut

travel cannot be adjusted as described, refer to

paragraph "i", following.

c. Table Supports Not Properly Adjusted.

Correct adjustment of table supports can be checked

with satisfactory accuracy, without removing the

table boards, by checking at the various positions on
