Overview

System Description

The Gear Front Attachment (GFA) system is used for tightening and loosening of screws and nuts. The

system can be used for screw connections in locations that are difficult to access.

The tightening operation is controlled by a separate drive unit to which the system is fitted. The drive unit

can be of either pneumatic or electric type.

The modular structure of the system allows for a wide range of configurations available for different screw

connections and tightening processes.

System Components

The modular GFA system is made up of the following main components:

Position Component Function

AAdapter With an adapter the GFA system can be fitted to different inter-

faces. The interface varies depending on the drive unit model.

The adapter can be of either fixed index or quick index type.

With a fixed index adapter the angle of the GFA system is speci-

fied from the factory. With a quick index adapter the operator can

easily change the angle depending on the application.

GFA-COT EN Product Information

Position Component Function

BGear Front Attachment

(GFA) module

The GFA module comprises a housing which contains a number

of gears, that is, the gear stage. The gear stage depends on the

length of the GFA module. The output gear, or output socket, can

be of type open-end or closed-end.

The open-end type can be used for pipe and hose connections.

The closed-end type is used for regular screw connections.

CStandard Socket With different sockets the GFA system can be used for various

screw profiles.

DHold and Drive

Socket

With a hold and drive socket the screw is kept fixed while the nut

is being tightened.

Installation

Installation Instructions

Assembly Instructions

The assembly procedure varies depending on the configuration. Make sure that the square drive of the

drive unit (1) matches the input gear profile (square hole) of the GFA module (2).

Functional Test

Perform a functional test before the first tightening operation, and after any performed maintenance activi-

ties.

To perform a functional test:

1. Turn the output gear wheel by hand. It should be turned easily.

2. If it is hard to turn, open the housing and check that all components are in the correct position.

3. Grease the system.

GFA-COT EN Operation

Operation

Ergonomic Guidelines

Consider your workstation as you read through this list of general ergonomic guidelines to identify areas

for improvement in posture, component placement, or work environment.

■Take frequent breaks and change work positions frequently.

■Adapt the workstation area to your needs and the work task.

■Adjust for a convenient reach range by determining where parts and tools need to be located to

avoid static load.

■Use workstation equipment such as tables and chairs appropriate for the work task.

■Avoid work positions above shoulder level or with static holding during assembly operations.

■When working above shoulder level, reduce the load on the static muscles by lowering the weight

of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce

the load on the static muscles by holding the tool close to the body.

■Take frequent breaks.

■Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.

■Adjust for a convenient field of vision that requires minimal eye and head movements.

■Use appropriate lighting for the work task.

■Select the appropriate tool for the work task.

■In noisy environments, use ear protection equipment.

■Use high-quality inserted tools and consumables to minimize exposure to excessive levels of vibra-

tion.

■Minimize exposure to reaction forces.

■When cutting:

A cut-off wheel can get stuck if the cut-off wheel is bent or not guided properly. Use the correct

flange for the cut-off wheel and avoid bending the cut-off wheel during operation.

■When drilling:

The drill might stall when the drill bit breaks through. Use support handles if the stall torque is high.

The safety standard ISO11148 part 3 recommends using a device to absorb a reaction torque

above 10 Nm for pistol grip tools and 4 Nm for straight tools.

■When using direct-driven screwdrivers or nutrunners:

Reaction forces depend on the tool settings and joint characteristics. Strength and posture deter-

mine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the op-

erator's strength and posture and use a torque arm or reaction bar if the torque is too high.

■In dusty environments, use a dust extraction system or wear a mouth protection mask.

Operating Instructions

Operating the GFA System

WARNING Risk of Injury

If the system moves around unexpectedly, or if reactive forces are absorbed incorrectly, it can lead to

severe injuries and property damage.

►Always check that the system is placed correctly on the head of the nut.

Operation EN GFA-COT

8© Saltus Industrial Technique AB - 9839 1815 01

WARNING Crushing Hazard

The Dual trigger forces the user to use both hands to operate the tool. If not used, the operator can

accidentally start the tool while adjusting the crowfoot, thus resulting in a serious hand injury.

►Make sure the tool cannot be started once the Dual trigger has been released.

►Always test the tool by first releasing the trigger of the Dual trigger, then push the trigger of the

tool. If the tool starts; stop working.

WARNING Risk of Injury

Make sure that the correct parameter file is being used. Wrong Parameter File might cause too high

torque with bodily injury as a result.

►Compare the maximum torque which is shown in the controller, with the maximum torque stated

in the stated technical data for the tool, they should be the same.

NOTICE Insufficient Lubrication

If the system is not sufficiently lubricated, it may be damaged.

►Lubricate the system as soon as there is no longer visible grease.

►Apply the grease gun to every grease nipple. Fill with lubricant until it emerges on the output socket.

Tightening procedure:

1. Place the GFA system (1) with the socket (2) onto the screw connection (3).

2. Check that the system is placed correctly on the head of the nut.

3. Start tightening by using the drive unit.

4. Remove the system from the screw connection. The system can now be positioned on the next con-

nection.

Changing a HAD Socket Bit

To Remove a Bit:

1. Loosen and remove the set screw from the socket.

2. Remove the bit.

GFA-COT EN Operation

To Insert a Bit:

1. Insert the bit into the socket.

2. Insert the set screw into the socket and tighten.

Service

Service Overview

As the gear wheels of the GFA module are exposed to hard wear it is important to regularly check their

condition. If any of the gear wheels are worn or damaged, all the gear wheels must be replaced. Needle

bearings are to be replaced if needed.

At regular intervals between the service, additional grease is to be supplied through the grease nipples.
