These instructions have been reformatted from Dykortech's original PDF manual, which was neither available on the web, nor easy to follow. John at Dykortech has been helpful in responding to several student and faculty emails, so I mean no disrespect in my repurposing of these documents.
First, Do No Harm
Note: Due to the geometry of the jib and how the camera weight is never distributed evenly (depending on its tilt and pan angle), the jib will tend to get a little tail-heavy when boomed up and a little head-heavy when boomed down. Be aware of these traits, and always securely hold on to the jib when operating and never leave loaded jib unattended.
Note: Two extra 1" long thumbscrews are provided. These are for locking off the jib boom and camera tilt. If planning to lock off the jib boom, screw thumbscrew into the threaded hole just below the dial platform pivot above the weight bar. To lock off the camera tilt, screw thumbscrew into the threaded hole above pan handle pivot. Remove these screws when not in use and when packing jib for transport.
Note: Make sure all lock-off screws, including fulcrum swivel, are loose before operating the jib. Operation with a locked-off fulcrum swivel could unscrew the jib from the tripod, causing serious damage and bodily harm.
Note: There is a considerable amount of play in the control assembly and camera head assembly. This loose play is required so as not to punt undo stress on precision parts (e.g., hydraulic cylinders). Do not tighten any seemingly loose bolts or nuts in these areas. Inspect the jib when it arrives and re-inspect occasionally to make sure nothing has come loose compared to original state.
Note: Before each use, visually inspect camera platform and control platform pivot points for loosened bolts (where the head and tail meet the jib arm). Tighten if necessary.
Note: The jib is designed to be as light as possible. Take extra precautions to avoid damaging it. Do not operate jib if you notice any broken parts. Keep jib dry and clean.
Always be aware of your surrounding when operating a jib. When working around people, make sure jib is assembled properly and all loads are secure. Have an assistant watching to avoid accidents. Dykortech does not recommend operating the jib over people.
Remove jib and accessories from jib bag. Lay jib on non-abrasive surface.
Note: Keep inner cardboard box for protection and bag shape retention, keep box for extension tubes to be placed in jib bag for transport.
Mount fulcrum to tripod (see fig. 2.1—2.4).
- Tighten swivel lock
- Screw fulcrum to tripod 3/8" stud
- Tighten setscrews and loosen swivel lock
- Mount on tripod and level
Remove keeper elastics from pan cables.
- Remove pin “A” (see fig. 4.1)
Note: If assembling 10 ft reach, it may be necessary to expand the hose coil diameter by rotating the head section counter-clockwise (see fig. 4.1).
- Separate head section from tail section. Turn head section perpendicular to tail (see fig. 4.2), leaving only one hose coil on the head tube (see fig. 4.3).
Attach standard jib extension (see fig. 5.1) and any other extensions (see fig. 5.2) to tail section.
Note: If installing a tail extension, it should be inserted before any other extensions (see fig. 5.3).
Note: Do not insert any hitch pins yet.
Use one hand to support the jib, and with the other hand pull the head section along the jib and attach the head onto the end of the extensions (see fig. 6.1—6.2).
Note: If hose coil becomes tight on tube, it may need to have a bigger diameter (See step 4).
Once the head is attached to the jib, it may be necessary to rotate the head clockwise to tighten the coil around the jib arm tube (see fig. 7.1).
Note: It is ideal to have the coil fairly snug around the tube to prevent the hoses from rubbing against the insides of the fulcrum uprights.
Lock extensions together with 2.5" hitch pins. Line up the holes top to bottom . Pin will go in easier if twisted back and forth (see fig. 8.1 & 8.2). Supporting the jib tube from underneath may help to line up the pin holes.
Mount assembled jib arm on to fulcrum using 3/8" pin (see fig. 9.1).
Note: It is good to lubricate this pin by rubbing it with a bar of soap. This will provide smoother operation.
Note: If using the tail extension, mount the jib arm using the 3/8" hole in the tail extension.
Insert 1/4" fulcrum pin (pin with black leader and hitch clip) into top hole of fulcrum while attaching big turnbuckle and leveling bar (see fig. 10.1–10.2).
Note: Be sure to have turnbuckle to one side of the fulcrum and leveling bar to other side.
Remove pin B from tail control platform (see fig. 11.1).
Use it to attach tail-leveling bar to control platform (see fig. 11.2).
- Install weight bar into the hole nearest to the jib arm (see fig. 12.1).
Note: If your jib has a second hole, do not use it.
- Mount several weights to the bar, but not enough to counterbalance the jib (see fig. 12.2).
Choose appropriate leveling cable. Hook it onto the turnbuckle at the fulcrum. Attach the other end to the camera head platform using pin C (see fig. 13.1–13.4).
Turn the turnbuckle to tighten the leveling cable until the camera head platform is horizontal. Be sure to hold the hook while turning the turnbuckle.
Note: A small after-market spirit level will help to level the platform.
Note: If camera platform is not perfectly level after camera is installed, it will not operate properly and may cause the platform to flip downward potentially causing damage to the camera.
Add weights to balance jib horizontally.
Connect pan cables together. Connect pan cable turnbuckle last (see fig. 16.1, 16.2).
Note: Do not cross pan cables. Feed pan cabled over top fulcrum pin.
Note: If assembling 7 ft or 10 ft reach, use appropriate pan cable extensions. If using tail extension, also use extra 10" pan cable extensions.
Note: Pan cables should be taut bug not tight.
Note: Be sure to check that the pan cables have not slipped off the head or tail pulleys.
Attach camera to quick release sliding camera shoe (see fig. 17.1).
Install proper camera balance spring onto head (see fig. 18.1).
Note: There are 3 springs available. The one with the least number of coils is for cameras in the 6–8 lb range. The one made from the same gauge wire and more coils is for cameras 4–6 lbs. The one made from thinner gauge wire is for cameras up to 4 lbs. A combo of 2 springs (left and right) can be used for cameras weighing up to 10 lbs. Do not overload the jib with a heavier camera; it was not designed for it.
Note: To test spring-to-camera compatibility — If the camera does not tilt full 90º down, you may need to first slide the camera forward on the mount. If this does not work, go with a lighter spring. Do not try to force the camera down with the panhandle; this may damage the control assembly.
Attach camera to jib (see fig. 19.1).
Attach monitor to fulcrum using bracket and two 1/2" thumb screws (see fig. 20.1).
Connect video and remote control cabling.
Note: Recommended RCA cables — Radio Shack 3 ft male to female RCA cables (Part # 42–2361)
Note: Recommended remote control cables — Radio Shack 6 ft hand/free head set extension cable (Part # 43–2003)
Install panhandle. Secure with thumbscrew, but do not over-tighten.
Install weights to counter-balance jib horizontally. Secure weights with 1" diameter weight bar spring clamps.
Tilt Reset Instructions
Take off the camera and spring(s) and try tilting the bare camera plate from the rear using the pan handle. If you notice that the camera plate is not tilting fully down, or fully back you’ll have to reset the tilt.
To reset the tilt:
- Take off the camera and counterbalance springs from the head.
- Using a small flat screw driver or knife, turn the little screws on the back of the valves a few turns counterclockwise to open the valves.
- Tilt the camera tilt plate all the way back slowly and pull the pan handle all the way down slowly so that the head cylinder shaft is all the way in and the tail cylinder shaft is pulled all the way out.
- Close the valves with the flat screw driver, snug the screws up but to not over tighten them, they are very small and you could strip the thread if you over tighten it.
Note: With regards to the tilt, the weakest spring is the one with the most coils (6 coils), the strongest has the least amount of coils,(4 coils).
- 6 coil spring - for cameras around 4 lbs like the Sony Z1U
- 5 coil spring - for cameras around 6 lbs like the Panasonic DVX100
- 4 coil spring - for cameras around 7–8 lbs like the Canon XL2/ H1
- 4 and 6 coil - for cameras around 10 to 11 lbs
- 4 and 5 coil - for cameras around 12–13 lbs
- 2x 4 coil springs - for cameras 13 to 15 lbs
