MISCELLANEOUS SERVICING INSTRUCTIONS
5.1
Advance Pawl Replacement
a.
Remove rear cover by removing the 4 securing screws (rear 2 screws under visor
stoppers) and raise and support Drive Arm.
b.
Using a thin bladed screwdriver, lever the spring from the hole in the bottom of the
pawl. Unscrew the slotted screw and remove slowly, being careful not to lose the
spacer.
c.
Position the pawl so the spring is located in the hole at bottom of the pawl. Put the
screw into the pawl so that the screw comes into the middle of the spring levers, slide
the spacer onto the screw and
attach to the pawl arm
assembly, tighten the screw.
d.
Carry out a functional check and if satisfactory replace rear cover.
5.2
Pawl Release Lever (Advance)
This lever is attached to the underside of the Long debris Blind Roller Support. 0µm and the
main arm is in the top position, the short lever holds the pawl away from the ratchet wheel.
This will leave a sufficient gap as to let the ratchet wheel rotate freely. Adjust the short lever
as required by moving the lever towards or away from the ratchet wheel at its pivot point.
5.3 Calibration
Calibration is set by selecting 2µm. One click from the pawl and ratchet wheel should be
heard.
Check by cutting wax sections so you can actually see the thickness change through micron
settings of 2, 4 & 6µm and that it is not cutting at zero thickness.
