5.1.1 Filter pressure reducer
The air from pneumatic systems is usually contaminated and enriched with moisture.
A filter pressure reducer with water separator must therefore be installed between the pneumatic system and
the tool. This not only regulates the operating pressure, but also cleans and dries the compressed air. The
utility and service life of the EFA pneumatically operated breastbone saw are thus considerably increased.
The filter pressure reducer should be installed as close as possible to the EFA pneumatically operated
breastbone saw.
You can purchase a suitable filter pressure reducer from
Schmid & Wezel GmbH
on request, through our
Sales department.
5.1.2 Spring balancer
The machine must always be operated in combination with a weight relief device (spring balancer (1)). Use a
trolley to attach it to a higher element above the workplace or to the ceiling.
Information on fine-tuning of the spring balancer can be found in
chapter 6.4.
Suspend the EFA pneumatically operated breastbone saw so it is top-heavy if possible (2). The vertical can be
readjusted if necessary (by selecting a different hole on the guide (2)).
Due to the weight (17 kg), there could be a hazard due to the machine slipping or falling when the weight relief
device is attached or detached. Also make sure that the machine does not jam on the snap hook. Be careful!
Caution!
Danger of injury when adjusting the spring balancer with an attached pneumatically
operated breastbone saw!
Before adjusting the spring balancer, remove the EFA pneumatically operated breastbone
saw!
Set an operating pressure of max. 8 bar at the filter pressure reducer.
