Setting Up the Tripod / Attaching the Slow Motion Handles
Stand the tripod on an
①
even and sold ground.
Adjust the height of the
tripod as the occasion
demands.
To change the height, loosen
※
the leg extension clamp of
each tripod leg. Be sure to
tighten all the leg extension
clamps securely after adjusting
the height of the tripod.
③ Take off the tray lock
knob at the center of
the tripod leg spreader
and reveal the screw
bolt.
Attach the slow motion control handles onto each
⑤
of the worm shafts for altitude adjustment and
azimuth adjustment on the mount. Orient the
metal sleeve so that the dent on the sleeve goes
to the flat portion of the worm shaft. Slide the
metal sleeve on the slow motion handle over the
worm shaft.
There are two altitude worm shafts, one on either side of the
※
altitude slow motion unit, and there are another two azimuth
worm shafts on the azimuth slow motion unit. Use whichever
one you find more convenient.
The two slow motion handles are the same and you can use
※
whichever for altitude slow motion control or for azimuth slow
motion control.
