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
GF-Primo / GF-Secondo Dolly System Instruction Manual
Page:
3
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:
o The 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.
o In 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).

This shows the voltage of the respective battery. By standing in front of the electronic housing and looking at
the HCU display, the battery on the left hand side of the display represents the battery on the left side of the
column. In turn the battery on the right hand side of the display represents the battery on the right of the
column.
Note: A fully loaded battery will show approximately 26 Volts. During use the voltage will naturally
become lower so that after approximately 200 lifts the voltage will drop below 20 Volts (when
the column is moving).
When a battery drops below 19 Volt the HCU display as well as the respective battery
symbol will flash in red. This signals that the battery needs to be changed and charged.
Should the battery voltage drop below 17 Volt the column will automatically switch off and
the display will show „DOLLY BATTERY LOW“.
Attention To ensure the best performance it is advised to use fully charged batteries. When the
voltage is under 19 Volts a performance drop can be expected.
Motor temperature:
The motor temperature is also shown on the display. It should be noted the temperature shown is that of the
outside of the motor in its isolated housing and not the ambient air temperature
Note: A safety guard is installed to protect the motor from thermal overload:
If, during operation, the motor temperature exceeds 55°C the HCU display will flash red and

the temperature digits will also blink. This signals the movement of the column must be
reduced or stopped. Upon reaching a temperature of 60°C the column will automatically
switch off and the display will show „MOTOR TEMPERATURE HIGH“.
Tip: To protect and ensure a long lifespan for the motor temperatures above 55°C should be
avoided.
Should a temperature of 55°C be exceeded, reduce or stop column movements for 30 to 60
minutes to allow the motor to cool down.
Attention: Over heating of the motor can be caused by over loading the column or driving the column
without load.
Note: During operation the generated heat by the electricity flow is at its highest in the centre of the
motor and spreads to the outside housing. The temperature is measured on the outside of
the motor which can be up to 30°C lower than the inner kern of the motor. Therefore by an
over load of the motor at 60°C it must be shut down as with an inner temperature of 100°C
permanent damage can be caused.
Limit:
LIMIT allows the operator to restrict the columns lift range by resetting the lower and / or upper end stops.
The lift range can be changed from its standard 0 to 705mm to, for example, 200 to 500mm. When reset, the
column can only be moved within the new range until it is or due to a Mode change the column is in a
position outside the new LIMIT range
Hand Control Unit HCU Battery Display:
In wireless mode the HCU is energized with its own battery and not with the columns batteries. The HCU
battery is inserted into the rear of the HCU. The voltage status of the battery is shown on the HCU display as
a battery symbol.
Ramp and Speed:
The columns speed and drive ramp may be adjusted in grades of 23 levels:
Speed Slow → Level 00 Fast → Level 22
Rampe Hard → Level 00 Soft → Level 22
(Longer acceleration and deceleration)

Check
o Are the HCU and column equipped with wireless modules?
o Is the emergency OFF Switch inserted into the off position? If so, twist clockwise
to deactivate.
o If the HCU battery is in place. The wireless mode does not work without battery.
o Are the HCU and electronic synchronized? If not, connect via the HCU cable.
o Are both the HCU and electronic sending and receiving on the same channel?
Error:
In wireless mode there is a disturbance in the movement of the column.
Solution:
Select the next or any other channel e.g. 4.
If this doesn’t help, change to cable operation.
Check the battery voltage with a loaded column. Should the voltage fall below 19V replace
or charge the batteries.
Check the motor temperature. In general terms the following can be said about the electromotor:
The hotter the motor becomes, the higher the performance loss. Should the motor reach a temperature of
60°C the column will shut down automatically to avoid permanent damage. However, it is suggested to avoid
use of the column when the temperature exceeds 50°C.
If the above solutions do not result in an improvement of the columns performance please service the
column (see “servicing the column”).

Error:
Upon switching on the column an incorrect height is shown!
Solution:
Calibrate the column.
If this doesn’t solve the problem and the error is still present, repeat the procedure.
Error:
Display is red:
Solution:
If the display is red it can have a few reasons and in general it is not necessarily an error
but also a signal.
If the display turns red it can mean either
o the connection to the electronic is disrupted.
o the motor temperature is too high.
o the battery voltage is too low.
In these cases
o in wireless mode switch both units to the next higher channel and check if there
is contact between both units.
