mounting the handwheel
The O-Focus DM incorporates a Minimal Backlash Mechanism
to guarantee precision focus pull with less play and higher
accuracy. Note that the assembly instructions apply to both
types of handwheel.
Push-fit the handwheel firmly onto the
main bridge.
The handwheel must be
fully engaged for the backlash-
reducing mechanism to be effective.
When mounting the assembled bridges and
handwheel onto the camera rods underneath
the lens: Turn the knurled screw clockwise to
tighten the rod clamp, then flip down to lock the
O-Focus DM securely on the rod.

Turn the lock lever clockwise to
secure the handwheel on the main
bridge.
NOTE:
Lock levers are fitted with a spring. Should a lever obstruct
the path of a camera rod, for example, adjust its position:
Pull the lever off the shaft as far as possible, turn it a few
degrees, then let it retract. Check the clamping is tight.
