Maintenance Adjustments and Alignments
5. Retighten the locking set screw securely to a required torque of 90-100 inch/lbs., after
adjusting each eccentric.
6. Replace the end cap
7. If any of the top rollers do not revolve when in contact with the top track it will be neces-
sary to remove the entire carriage to closely check each roller bearing. If bearings do not
revolve, and thorough cleaning doesn’t make them all free to revolve, the defective ones
should be replaced.
Note-Too much pressure on the roller bearings will cause excessive and unnecessary wear in
the parts and make the carriage work harder. Seven to ten pounds average pull on the car-
riage is a desirable preload.
Caution! Disconnect and lockout power supply before making any adjustments or alignments.
Adjustment of the Rollerhead to Arm
Accurate work cannot be done if the roller bearings of
the motor carriage are not in proper adjustment. When
play develops between the rollerhead and the arm the
following adjustment is required:
1. Remove the arm end cap by taking out the two
socket head cap screws in the front of the end cap.
2. Clean the tracks thoroughly. Wipe them clean with
a solvent,
do not
use kerosene. Use extreme caution
as most solvents are toxic and/or flammable.
Do not
grease or oil the tracks.
3. Loosen the locking set screws (A) on the two left
hand 45
o
bearings (C) just enough to loosen them
(1/6 of a turn or less).
4.
Using a 1/4” allen wrench and a light behind the
rollerhead, adjust the eccentric studs (B) on the left-
hand side bearings until all 8 bearings contact the
track. Attempt to equalize the load on the front and
rear bearings by putting the same load on the front
and rear eccentrics.
Adjustment of the Yoke Clamp Nut
If
the yoke clamp nut (A) becomes too loose the fol-
lowing steps will correct this condition:
1. Tighten nut (A) counter clock wise until yoke is
tight.
2. You should always check your saw for accuracy
after any adjustments. (Refer to pages 25,26,27)
