USA

10. Slide the 3/8” long
black spacer with the
5/16” diameter ball
bearing inside into the
carriage at the rear end
of the lead screw.
11. Re-attach the carriage end plate using the (5) Phil-
lips head screws. TO AVOID STRIPPING THE THREADS,
DO NOT USE A POWER DRIVER DURING ASSEMBLY.
12. Hand thread the set screw into the end plate.
This set screw is used to remove end to end play in
the Lead Screw Assembly.
ROTATE THIS SET SCREW
WITH YOUR FINGERS ONLY
until end to end play is
removed. You can test for end play by pushing and
pulling on the Red Micro Adjust Knob. Once the end
play is removed, use a 1/8” hex key to hold the set
screw in place as you thread on and tighten the lock-
ing nut.
DO NOT USE THE HEX KEY TO TIGHTEN THE
SET SCREW. EXCESSIVE PRESSURE ON THE END OF THE
LEAD SCREW WILL NOT PERMIT EASY ROTATION AND
MAY DAMAGE THE FENCE MOUNTING BRACKET!
After
tightening the locking nut, check for end play and
fine-tune as necessary.
13. Replace the ball
bearing, followed by
the spring and the
set screw through
the hole located in
the front of the fence
mounting bracket.
Thread the set screw in until it is just below the face of
the fence mounting bracket.
DO NOT TIGHTEN THIS
SET SCREW.
14. If converting to the Metric Lead Screw Assembly,
remove all existing scales on the top of the carriage
and replace with (1)
430mm
Lexan scale and (1)
Stainless Steel scale.
TO AVOID STRIPPING
THE THREADS, DO
NOT USE A POWER
DRIVER DURING
RE-ASSEMBLY.
