F Series - HF Router Maintenance and Adjustment of Spindle Collet

There are two types of spindle motors:

• 4041-DC-S
• 5045-DC-CS

First check what type of motor you have before you setup the spindle collet.

• Mechanically the system you can recognise by the adaptor ring. The old type of spindle motor 4041 does not have and adaptor ring:

• Router type (1) is indicated on the label on the side of the spindle motor

Installing the collet

In the system 4041 DC-S with collet C4, the collet set process is as follows: 

1. Apply compressed air
2. Screw in the collet with inserted tool or c-lock pin
3. Adjust the stroke by loosening the collet ½ turn
4. Insert and tighten the set screw to prevent the collet from turning 
5. Insert the tool 
6. Stop compressed air supply 

Attention: The collet is not protected against rotation/loosening if the set screw is not firmly tightened

Maintenance

• Clean the collet every week and insert it according to the set process.
• During yearly maintenance, replace the collet to ensure maximum clamping power.
