OPERATION
Ballhead Operation (continued)
TENSION THUMBSCREW
(BC-217T & BC-226T BALLHEADS)
The tension thumbscrew is
integrated into the main locking
knob. It’s used to control the
amount of friction on the ball in
order to maintain strict control
when positioning it.
ADJUSTING THE FRICTION
(BC-217T & BC-226T BALLHEADS)
To adjust the friction accurately,
follow these steps:
1. Tighten the head and mount
the lightest combination of
camera and lens that you
will regularly use. Turn the
tension thumbscrew (located
on the main locking knob)
counterclockwise until it stops.
2. Turn the main locking knob
counterclockwise until you
reach the secured minimum
degree of friction. You can set
the friction so that the ball
moves freely or so that it is
immobilized or anywhere in-
between.
3. Turn the tension thumbscrew
clockwise until it stops. You
have now set your minimal
friction limit for this particular
camera and lens combination.
The main locking knob will
not turn beyond this minimal
friction limit.
