The sequence of tightening screws on the LGD’s is important.
✓
Step 1. Tighten the LGD mount screw
securing it to the guide bar. Critical: the
drive shaft/gear hub must be centered
with the opening on the bracket.
✓
Step 2. Pivot the larger gear onto the lens
gear such that it makes intimate contact.
Carefully observe that the gear is still
properly aligned and the drive shaft/gear
hub is centered with the LGD bracket (see
photo). Tighten the two pivot screws
gently to secure it in position.
✓
Step 3. Firmly tighten the screw that
couples the drive gear hub to the drive
shaft.
TIP
. The gear hub / drive shaft coupling acts
like a clutch
– the drive shaft will ‘slip’ when
reaching the end of travel in either direction.
Tightening the screw more will allow less slip.
Adjust this amount of slip at your discretion.
✓
Set the focus/iris indicators. The left and right side Gear Controls have silicone
bands. The white silicone can be marked to indicate focus / iris position.
Center the drive shaft/gear hub to the
bracket. Tighten the screw and secure
the LGD to the guide bar.
With the drive shaft/hub centered, pivot
the larger gear to make intimate contact
with the lens gear. Gently tighten 2 pivot
screws.
