Fig. 10— The fl at blade of the screwdriver should be positioned perpendicular to the
adjustment ring to make the ring easier to rotate.
4. The perpendicular position of the screwdriver creates a leverage point for using the
screwdriver to amplify the force applied to turn the ring.
CAUTION
: Don’t unscrew the setscrew too much or it will fall out.
CAUTION
: Be careful not to let the screwdriver blade slip out of the screw slot,
which could damage the slot or cause personal injury.
TIP
: With older manipulators, the Adjustment Ring may be too tight to turn, even using
the screwdriver technique just described. If this is the case, remove the Y-axis
Adjustment knob to gain better mechanical access for the use of pliers.
To remove the Y-axis Coarse Adjustment knob, remove its black locking nut with the
502105
tool. Then, turn the knob counter-clockwise to remove it altogether. Note
the order and orientation of the nylon and spring washer friction components. When
the Z-axis tension adjustments are complete, re-install the friction components and
the Y-axis Coarse Adjustment knob in reverse order of disassembly. Then, re-adjust
the Y-axis tension.
