GF-Primo / GF-Secondo Dolly System Instruction Manual
SAFETY GUIDELINES
Adherence to the instruction manual:
The set-up instructions must be read and understood before set-up or operation. The dolly may only be assembled in accordance with the manufacturer’s instruction manual. The manufacturer’s technical specifications and limits (maximum rated loads etc) must be adhered to at all times and in no way exceeded.
Warranty:
The manufacturer accepts no liability for damages or injuries for incidents or accidents occurring due to negligence by the crane operator or misuse of the crane or disregarding the instruction manual.
Assembling and operation of the dolly:
The Dolly may only be set-up or operated by trained and experienced personnel. To assemble and operate the dolly at least 1 trained person is required. To avoid misuse by untrained personnel, the dolly should be dismantled / switched off when not in use or under supervision.
The crane may not be set-up or operated under the influence of alcohol, drugs or any other intoxicating substances. The respective protective clothing e.g. gloves, should be worn.
Stability of the crane system:
Before assembling or using the dolly ensure that the ground surface is stable and cannot give way. The ground surface must be stable enough to support at least 1000 kg/m2 = 2200 lbs/ sq yard.
Dolly operation with the GF-Primo Jib is only allowed with solid tires and use with pneumatic wheels is not allowed. Before and while using the dolly wheels should be inspected.
Intended use of the Dolly system and use of the Dolly system with Jib Arm:
The Dolly is a mobile personnel and camera support system for use on sets and studios with even and level ground / floors. Also for use on GF-Track.
Standard dolly operation consists of a for lifting 1 to 2 persons and camera or lifting the camera only, without personnel on board, electromechanical column for lifting 1 to 2 persons and camera or lifting the camera only, without personnel on board.
In Jib mode a pan and tilt arm is mounted for lifting 1 to 2 persons and camera or lifting the camera only, without personnel on board
In accordance to the safety guidelines the dolly/jib is only allowed to be used on solid, level and stable ground with solid wheels, not pneumatic wheels.
The dolly/jib movement on the ground, rotation of the column is managed by at 1 to 2 experienced, trained and authorised personnel from the hand grips and /or the provided steering handles.
Panning movement of the turnstile mount / column can also be made by the personnel sitting on the column/dolly when seated on the provided seats.
Vertical lift of the column is controlled via wireless or cable control operated by an experienced, trained and authorised person.
Operation of the dolly/jib is only allowed within the limits and guidelines mentioned in this instruction manual.
The dolly must be operated on level, stable surfaces at all times or on dolly track. Whether operating or moving the dolly on track or on a solid ground surface it is essential that the track or surface is completely level, stable and free from obstructions.
When operating the dolly on track, ensure that the track is level, properly laid, constructed and supported. The correct underlay must be used to ensure that the track and underlay are secured against moving, slipping and collapse. Ensure that the underlay meets the specified support and stability requirements. Only GFM Track or comparable track systems with a payload capacity of 1200kg / 2640lbs and a maximum track runner distance of 640mm / 25inches (measured inside edge to inside edge) may be used.
Extreme caution if tracking on curved track (not faster than a slow walking pace)!
Use of the dolly on insert vehicles, camera cars or any motorised vehicle is not allowed. The manufacturer accepts no liability for damages or injuries for incidents or accidents occurring due to use of the dolly on insert vehicles, camera cars or any other motorised vehicles.
Operation of the Dolly/ Jib:
The complete lift and panning range of the dolly/jib must be kept clear of obstructions at all times. A safety clearance of 1m / 3' 3" must be observed on all sides of the dolly/jib during operation. Only authorised, trained and experienced personnel are allowed to operate the dolly/jib. The dolly/jib may not be set-up or operated under the influence of alcohol, drugs or any other intoxicating substances. The respective protective clothing e.g. gloves, should be worn.
The dolly may not be used in the direct vicinity of high voltage power cables. To avoid accidents due to misuse in the vicinity of high voltage power cables, Safety Guidelines especially BGV A1 and A2 (formerly
Page: 2
GF-Primo / GF-Secondo Dolly System Instruction Manual
VBG 1 and 4) as well as VDE regulations (especially 0105 part 100) must be adhered to. If the nominal voltage cannot be determined, a minimum clearance of 5m / 16ft must be kept at all times.
Failing to do so can cause fatalities!
Personnel on board the jib's platform must use safety belts at all times. They should not make any sudden, abrupt movements or lean out over the side of the platform. No loose objects may be stored or placed on the dolly platform.
In the interest of safety, when operating or moving the dolly/jib, abrupt, sudden movements of the dolly should be avoided. An element of risk remains by people moving in the operational range of the dolly/jib. The dolly operator has to be trained on that and is only allowed to operate the equipment in a safe range.
Before operating the dolly/jib all connections, mounted accessories, safety pin as well as every connecting bolt must be checked for a proper fit.
Dolly accessories:
For safety reasons only original accessories manufactured by GFM may be used with the dolly.
Procedure in case of accident or damage:
In case of accidents caused by disregarding the manufacturer’s instruction manual, please proceed as follows:
oThe manufacturer should be immediately informed of any damage to the dolly and the severity of the damage. Damaged dolly parts should be sent to the manufacturer for evaluation, repair or replacement.
Use of the dolly with damaged parts is not allowed. The manufacturer accepts no liability for damage or injuries for incidents or accidents occurring due to the use of damaged parts on the dolly.
oIn case of damage or accidents with injured people local applicable as well as employment property right regulations may be adhered.
Safety Guidelines for dolly operation:
To avoid collisions, ensure that the columns lift range is free from obstructions!
When working with off-set arms ensure that the mounted payload is counter balanced! Never exceed the manufacturers payloads
In an open space the wireless mode range is approx. 100m / 330yards
In general, the hand control unit should never be left on when not in use or when not under supervision.
To avoid unwanted movement of the column due to misuse or accidental activation of the rocker switch / hand control unit, ensure that the main electronic switch is OFF when not in use or not under supervision.
The equipment must be handled carefully at all times.
Do not operate or drive the column without payload on the column. At least 1 person and camera should be on the column when it’s moving.
Attention: Should the HCU software be older than versionr 3.8.5 or the electronic be older than version 3.7.3 or if you gave a software where it is not 
possible to check the version please note that after using the
Emergency switch the column must be calibrated (see page 39)

Technical Specs for GF-Primo - / GF-Secondo Dolly
The difference between the GF-Primo - and GF-Secondo Dolly is effectively the different base dollies. The columns are identical.
The GF-Primo Base has a central "one touch" selector allowing for immediate, one handed, switch over to crab, front or rear wheel steering. GF-Secondo Base Dolly can also switch from crab, front or rear wheel steering but to do so, each wheel must be adjusted individually. The GF-Secondo also has 2cm more ground clearance (column to ground).

The Base Dolly
Changing the batteries
The dolly’s’s batteries are connected to the column with a user friendly “drop & go” system.
The column requires 2 x 24Volt Battery units to function.
Centre the battery over the locking mount. Move the battery into position and drop it gently onto the locking shaft.
Locking shaft & knob
Open the left and right locking knob to mount the battery. When in place, hand tighten the knobs to secure the battery.
Connecting the Platforms
The Standard Multifunctional Platform Set
The platform set consists of 4 units. Each platform is machined to provide a selection of threaded (10mm & 3/8”) and non-threaded holes (12, 25 & 28mm).
3 of the units are identical and fit on any of the 3 sides of the dolly. The 4th unit is machined slightly differently and fits only on the side of the dolly where the steering gearbox is located.
The carry handle double functions as a lock for the platforms. Extend the handle by pressing the stainless steel button on the left side of the wheel arm. At the same time pull the handle out.

GF-Primo / GF-Secondo Dolly System Instruction Manual
Attach the required number of platforms. To secure them, press the stainless steel button and push the handle towards the dolly. When the handle is engaged in the locked position you will hear an audible click and the button will be extended i.e. not flush with arm.
By using seat arm extensions the standard platforms can also be combined to form steps and low platforms.
Special “drop in” pins are required. The pins are inserted from top to bottom and securely bolted on the bottom joint.
Attention: When using the platforms ensure that they are mounted and fitted correctly. The platform must fit snuggly to the dolly frame with no gap 
inbetween. Ensure that the steel pin on the locking handle is engaged
correctly as described above i.e. the steel pin must be visible!
Mounting the Low Platform System
The 2 part Multifunctional Hi/low Platform can be dismantled by unscrewing 2 bolts, allowing the wider platform part to be mounted on the base dolly as described on the previous page
