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 op-

eration of the Miller Projib, please observe the following precautions:

SAFETY 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 counterbal-

ance 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 EQUIPMENT 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 mount-

ing 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 MAINTAINING A LEVEL POSI-

TION 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 counterbal-

ance 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. CAUTION! DO NOT LOOSEN

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-clockwise rotation reduces drag. Pan and tilt

drag are adjusted by the operator to personal preference and to achieve

correct motion for shooting requirements.
