Pneumatic connection (EFA SK 08D)
A faulty compressed air connection and a high proportion of water in the compressed air may cause water to escape at the connection point.
Therefore, ensure that the hose connection is correct and that the water content in the compressed air is low (drain the water separator regularly).
If no dried air is available, the customer must install a water absorber.
Before connection, remove impurities by
blowing air through the compressed air hose using a compressed air gun.
4.2.2 Filter pressure reducer
The air from compressed-air systems is usually contaminated and has accumulated moisture. Therefore, a filter pressure reducer with water separator should be installed between the compressed air system and the tool. This not only controls the operating pressure but cleans and drains the compressed air. In addition, this improves on the usefulness and increases the service life of the pneumatic circular saw significantly.
The filter pressure reducer should be installed as close as possible to the pneumatic circular saw.
Set the operating pressure on the filter
pressure reducer to max. 8 bar.
You can purchase a suitable filter pressure reducer on request from our sales department at Schmid & Wezel.
4.2.3 Spring balancer
The machine must always be operated in combination with a weight relief system (spring balancer). Install this with a sliding trolley above the working area on an element assembled higher or on the ceiling.
Information on fine adjustment of the spring balancer is provided in Chapter 6.2.
Hang the pneumatic circular saw as top-heavy as possible. The vertical position can be adjusted if necessary.
Attaching or removing the weight relief may result in a risk of the machine slipping or falling due to weight (depending on the version between 2.5 and 9 kg). Also make sure that the machine is not jammed by the snap hook
