ANGLE BRAKE ADJUSTMENT
The clamping force on the swivel brake can be adjusted to ensure that the Head
is held securely and does not move during cutting. The brake handle should be
adjusted so that it does not "bottom out" or hit it's movement limit, yet holds the
head securely.
ANGLE BRAKE ADJUSTMENT PROCEDURE
STEP 1 Loosen locking cap screw "B" with a 1/4 allen key.
STEP 2 Tighten all 4 set screws "A" until snug with a 5/32 allen key.
STEP 3 Back out the "A" screws 1/4 of a turn.
STEP 4 Tighten the locking cap screw "B".
STEP 5 Swing the head to 45
O
and back to ensure that the head moves freely
and does not bind on the pivot surfaces. Continue to step 6 if necessary.
STEP 6 Adjust the clamping force bolt "C" with a 3/4" wrench. If tightened too
much the locking handle will "bottom out" and not hold the head firmly.
DRIVE BELT REPLACEMENT
The drive belt on the S-23 is a long life grooved belt. It should last for many of hours of operation and should
rarely require replacement. See the BLADE DRIVE ASSEMBLY drawing on Pg 6.2.
HEAD DOWN LIMIT SWITCH
The Head down limit switch operates to cut power to the blade motor and the
coolant pump motor when the Head has descended to the bottom of its travel.
The Head is adjusted so that the blade will descend slightly past the level of the
vise wear strips. This setting is critical to ensure that the blade has cut fully
through the stock. The Head Down Limit Switch is located at the back of the
head near the head cylinder.
Adjustment of the limit switch is made by changing the position of the set bolt
which is located beside the horizontal pivot pin on the pivot link. Lengthening the
set bolt will cause the limit switch to activate sooner as the spring post meets
the limit switch roller. Shortening the setting bolt by turning it into the pivot link
will lengthen the time before the Head limit switch is activated.
