Connecting the EFA pneumatically operated breastbone saw
Attention! Device damage!
Operate the EFA pneumatically operated breastbone saw only with clean, water-free and oiled
air!
Insert the air hose (1) as far as it will go into the screw-in fitting (2) on the valve housing (3) of the EFA
pneumatically operated breastbone saw.
Screw the air-outlet hose (4) onto the valve housing (3) of the EFA pneumatically operated breastbone
saw.
Connect the EFA pneumatically operated breastbone saw to the oil mist lubricator (6) with the thread
nipple of the air hose (5) (with filter pressure reducer).
Make sure that the oil mist lubricator is assembled in the following sequence: water separator (7), pressure
gauge (8), oil mist unit (9).
The oil mist lubricator and the air hose are not included in the scope of supply but can be
purchased on request from our Sales department at Schmid & Wezel GmbH.
 Air hose: Part no. 311 366 811
 Oil mist lubricator: Part no. 311 367 043
To ensure lubrication of the pneumatic motor, the oil mist lubricator must be set to 2 – 3 drops of oil per minute
(or one drop of oil for approx. 15 cuts).
If the compressed air connection is faulty and there is a high water content in the compressed air, water can
escape at the connection point.
Therefore, make sure that the hose connection is correct and that compressed air with a low water content is
used (the water separator must be emptied regularly).
If no dried air is available, a water absorber must be installed by the customer.

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.
