Operational*Tips*
1. The!GH30C!is!rated!with!a!maximum!load!capacity!of!33!lbs!/!15!kg.!This!assumes!a
properly!balanced!load.!If!the!camera!and!lens!are!not!properly!balanced!there!is!a!danger
of!tipping!and!falling!which!could!lead!to!damage!to!your!equipment!or!to!you!person.
Always!be!sure!to!properly!balance!your!rig.
2. Be!advised!that!while!the!GH30C!can!handle!a!load!up!to!33!lbs!/!15!kg!your!tripod,!to
which!the!GH30!is!attached,!must!also!be!able!to!handle!this!load,!including!movements!you
will!apply!to!the!rig!via!the!gimbal!(swings!and!pans).
Here!are!some!tips!to!help!ensure!a!stable!tripod!setup:!
-If!possible,!attach!the!GH30C!directly!to!the!column!platform!of!your!tripod.!Do!not!connect
the!GH30C!to!a!ball!head!or!pan/tilt!head!as!this!will!greatly!reduce!stability.
-Always!use!the!tripod’s!legs!to!achieve!your!desired!working!height!rather!than!its!column.
Only!extend!the!column!if!absolutely!necessary.!Extending!the!column!of!the!tripod!greatly
reduces!stability.
-If!your!tripod!has!multi-angle!legs!and!you!can!achieve!your!desired!working!height!with
the!legs!set!at!a!wider!angle,!thereby!creating!a!larger!base,!do!so.!This!improves!stability.
-Always!be!sure!your!tripod!is!level!even!if!the!ground!it!is!placed!on!is!not.!Use!the!leg
adjustments!to!achieve!a!level!state!for!the!gimbal!before!mounting!your!camera!and
balancing!it.
3. Cold!weather!performance!is!only!a!guide.!The!GH30C’s!performance!in!cold!weather!can
be!affected!by!moisture!as!well!as!temperature!and!load.!With!increased!in!moisture
and/or!decreases!in!temperature!you!will!notice!the!GH30C’s!movements!begin!to!slow
down!as!the!unit’s!joints!become!stiff.!In!this!case!you!may!want!to!be!sure!all!of!the!tension
adjustments!on!the!GH30C!are!set!to!their!loosest!setting!to!regain!movement.!If!possible,
do!your!best!to!keep!the!GH30C!dry!to!prevent!moisture!from!affecting!performance.
