Micro switch adjustment
The micro switch system must be adjusted at working pressure according to the “Technical data”
Page 4 according to the below procedure to ensure full functionality and lifetime.
1. Turn the flow regulation to maximum flow.
2. The machine must be running high pressure, and flow, according to the specification in the
“Technical data” Page 4.
3. Screw the M5 nut on the adjustable key until there is a clearance between key and micro
switch (green), which can be felt by moving the arm backwards and forwards, with a light
touch from a finger (yellow arrow)
4. Unscrew the M5 nut (counter-clockwise) carefully, until the key just touches micro switch,
the clearance must only just disappears = “0 preload and 0 clearance”.
5. Carefully turn the M5 nut 90°±30° clockwise. This will move the key approximately 0.2mm,
away from the micro switch.
6. Check that there is a clearance between the key and the micro switch.
7. Apply Loctite 454 on the key end to lock the M5 nut. Then the key adjustment is finished.
8. Check as last point that there still is clearance between the key and micro switch.
