Maintenance Adjustments and Alignments
Caution! Disconnect and lockout power supply before making any adjustments or alignments.
Your saw has been completely assembled, aligned and tested at the factory...then partially disassembled for shipment. Han-
dling during shipment may cause some misalignment and the following information will enable you to correct any cutting
inaccuracy you discover. These adjustments may also be necessary after a period of use. (See preventive maintenance)
Important ...
Since one adjustment may affect another it is important to run through the adjustments in the sequence as
follows.
Adjustment of Base to Column Fit
If excessive side motion exists at the end of the arm when the
arm clamp is engaged and the column clamp is released,
adjustment to the base or bronze gib is generally necessary.
To adjust:
1.
Loosen all locknuts, setscrews and bolts and pull column
clamp handle forward.
2.
With the motor and yoke in the rearmost position the
elevation effort should be easy.
3.
Tighten the bottom pinch bolt (A) until there is an in-
crease in the elevation effort. Bottom the jack screw (B)
against the opposite side of the slot; this will lock the
pinch bolt.
4.
Tighten the gib screw (C) hard, then back it off. Run it
back up against the gib lightly, then snug up the locknut
(D).
5.
With the column clamp handle in the forward position
insert a 1/4” allen wrench into column clamp bolt (E) and
turn it clockwise until all play is removed from the col-
umn clamp handle. Lock the handle adjustment by
tightening the bolt (F) on the opposite side of the base.
Adjustment of the Arm Clamp
If the arm will not clamp tight on the column:
1.
Place motor carriage in the rearmost position.
2.
Pull the miter handles (A) forward.
3.
Tighten upper arm pinch bolt (B) until slight resistance
to arm swing is felt.
4.
Swing the arm to the left 10
o
until the two locking set
screws (C) are aligned with an oblong hole in the bottom
of the column collar (D).
5.
Loosen the two set screws.
6.
Use a 1/4” allen wrench to tighten the arm clamp screw
(E) by rotating clockwise.
7.
Retighten the two locking set screws securely to a re-
quired torque of 200-225 inch/ lbs. They must be tight to
prevent clamp screw slippage.
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 sol-
vents 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.
