INTRODUCTION

The Miller Projib is a versatile camera mount; designed to add the

dimension of tracking and elevation to the normal range of

movements afforded by your fluid head. It is designed for use in

professional film and video production by professional support

equipment operators. For safe operation of the Miller Projib,

please observe the following precautions:

AFETY INSTRUCTIONS

The Safe setup and operation of this equipment is the responsibilty

of the operator. This equipment is to be set up and used by

qualified personnel only.

A Miller Projib, when loaded with camera, fluid head and counter-

balance weights, exerts a considerable amount of leverage on the

surface it is attached to. For this reason, precautions must be

taken to prevent accidental over-balancing. ACCIDENTAL OVER-

BALANCING OF THE PROJIB MAY CAUSE EXPENSIVE EQUIP-

MENT DAMAGE AND SERIOUS PERSONAL INJURY. The risk of

over-balancing is reduced by adding suitable ballast, such as

sandbags, to the base of the tripod or dolly to which the Projib is

attached. THE USE OF SUITABLE AND SUFFICIENT BALLAST

IS ESSENTIAL TO SAFE PROJIB OPERATION.

The Miller Projib is designed to attach to most professional heavy

duty tripods or hi-hat type dollies. FOR MAXIMUM STABILITY

WHEN USING TWO STAGE TRIPODS, ENSURE THAT THE

LOWER TUBE LEGS ARE COMPLETELY COLLAPSED.

The total payload must not exceed the capacity of the tripod.

NOTE: Make sure all items on the jib, (fluid head, camera and

counterbalance weights), as well as the jib itself, are considered in

assessing the weight of the payload. The jib is designed to carry a

camera and fluid head weight up to 50 lbs. (22kg) maximum.

If the Projib is mounted on a dolly, the dolly should be of a heavy

duty type with sufficient additional payload capacity to accept

sandbags or similar safety ballast to prevent over-balancing as

cautioned above. FAILURE TO OBSERVE THIS PRECAUTION

MIGHT CAUSE THE ASSEMBLY TO OVER-BALANCE IF THE

DOLLY IS BROUGHT TO A SUDDEN STOP AT THE END OF A

TRACKING MOVEMENT.

COUNTERWEIGHTS

Miller recommends the use of standard, rubber covered circular

bar-bell weights as suitable counterbalance for the Projib. For the

average camera/fluid head payload of between 15kg (30lb) and

20kg (45lb), a suitable combination of 5kg (10lb), 7.5kg (15lb) and

10kg (20lb) bar-bell weights is recommended.

PROJIB SETUP

1. Remove the Priojib from the protective carry case and flip over

the fluid head mounting plate so that the threaded male and

female mounting connectors are aligned. Join the connectors and

hand-tighten only.

2. Attach the Projib to the tripod using the clamp nut provided.

Note that the main body of the Projib at the pivot point is fitted with

a spirit level. Adjust the legs of the tripod so that the spirit level

indicates a level position for the PROjIB. FAILURE TO LEVEL AT

THIS POINT FIRST WILL PREVENT THE PROJIB FROM MAIN-

TAINING A LEVEL POSITION THROUGHOUT THE RANGE OF

MOTION OF THE PROJIB ARM - REGARDLESS OF OTHER

ADJUSTMENTS! Correct levelling of the tripod bowl or dolly hi-hat

is important and should be checked regularly during operation. Do

not adjust the level of the tripod or dolly with the camera fitted.

3. Loosen the lock nut that controls the motion of the sliding

counterbalance arm at the rear of the Projib. Slide this arm out so

as to achieve a balance in the Projib over the pivot point at the

tripod.

PROJIB SETUP contd.

4. Attach a 100mm ball levelling fluid head to the jib mounting

plate. View the 2nd spirit level, located on the fluid head mounting

surface of Projib. If it is not indicating level, first check to make

sure that the central pivot point is level. Once that is confirmed,

loosen the lock ring that is located at the base of the parallel tube

under the jib arm near the central pivot point at the tripod. CAU-

TION! DO NOT LOOSEN THE LOCK RING FOUND NEAR THE

FLUID HEAD MOUNTING SURFACE WHICH IS USED ONLY TO

RETURN THE PROJIB TO STORAGE POSITION. Once the lock

ring near the center of Projib is loosened, turn the entire parallel

tube beneath the jib arm in or out until the fluid head mounting

surface is indicating level in the #2 bubble level. Tighten the lock

ring in this position. Now level the fluid head using the bubble

level on the fluid head. Once all three bubble levels are indicating

level, the camera will remain level throughout the jib's operational

range.

5. Mount camera to fluid head and add sufficient weights to rear of

jib (or adjust length of jib counterbalance arm) to balance camera.

CAUTION: THE PROJIB COMES EQUIPPED WITH A LARGE PIN

WHICH WILL PREVENT ACCIDENTAL DETACHMENT OF THE

WEIGHT RETAINING NUT DURING JIB OPERATION. BE

CERTAIN THAT THIS COTTER PIN IS IN PLACE DURING JIB

OPERATION.

OPERATING CONTROLS

The Projib is fitted with pan and tilt drag controls and positive tilt

lock for the jib arm vertical movement. The tilt lock is easily

distinguished from the tilt drag by the large cone shape thrust

locker located under the tilt lock knob. Rotating the drag adjusters

inward (clockwise) increases the amount of drag; counter-clock-

wise rotation reduces drag. Pan and tilt drag are adjusted by the

operator to personal preference and to achieve correct motion for

shooting requirements.
