Installation
Installation Instructions
Assembling the frontal support
The MTRwrench cradle is delivered with cradle support for 85/200 Nm (4027004805) included in the box.
The MTRwrench cradle required support to hold the MTRwrench in the correct position during charging.
|
|
|
Remove the screws (2) and the support (1).

The support is not to be used for wrenches of 25 Nm and 50 Nm capacity.
The support must be used with wrenches of 85 Nm and 200 Nm capacity.
Install the support (1) with the screws (2).
Loosen the screws (3) to adjust the position of the support (1).
Adjust the position so that the support (1) is in contact with wrench tube.
Tighten the screws (3) and the support (1).
Installing the charger
The MTRwrench cradle can be installed both horizontally and vertically, on a tabletop or in a cabinet.
|
|
|
Slide the horns of the mounting plate (1) into the corresponding holes in the bottom of the MTRwrench cradle.

The vertical mounting plate (1) has slotted holes for mounting onto walls, tabletops or cabinets.
Make sure the mounting is stable and secure.
Remove the screw cover (4).
Install the washer (2) and the screw (3) into the hole and tighten at a torque of 1.5 Nm.
Install the screw cover (4).
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 vibration.
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. Always 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 determine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the operator'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.
