Upper Arm (R or L)
NOTE: This instruction applies to all variations of arm locks. Make sure to use the
screws that came with the kit if you are installing a complete
arm assembly.
Tools Required
Phillips screwdriver
1. Loosen knob.
Grease or silicone (white/clear preferred)
2. Remove 2 screws.
NOTE: If you are installing a new arm
assembly, make sure to use the screws
that came with the kit, not the screws
removed here.
4. To install upper arm, do above
steps in reverse order.
B. Wipe a little grease inside top 4" of
lower arm tube before installing. This
prevents squeaking of arm lock & tube.
D. When tightening screws in Step 2,
make sure screws go into the holes/
indents on the arm lock, not against it.
The arm lock must float freely. The
screws keep arm lock from coming out.
3. Slide cap up arm, and then pull
upper arm out of lower arm tube.
INSTALLATION NOTES:
A. Make sure components are properly
installed before installing arm.
NOTE:
arm lock may be either white or black.
C. The machine key always faces and
comes in contact with the stud end of
the knob and the holes/indents align
with the screws on the bottom of the
tube. R and L arms tilt inward ~ 20
°
.
