9. PROCEDURE FOR REPLACEMENT OF CABLE COLLETS
Ensure the air supply is disconnected from the blowing machine before
carrying out this procedure.
Tools Required 4mm Allen Key
Step 1
Collet Removal
▪ Ensure that the air valve is closed and the air pressure is at
zero.
▪ Open the air chamber to expose the collets.
▪ Remove the socket head cap screw (2) using a 4mm Allen
key and remove the collet (2)
Step 2
Collet Refitting
▪ Select the replacement collets (refer to appendix 7 for collet information)
▪ Clean the air chamber with a dry cloth.
▪ Fit the appropriate collets and secure with a socket head cap screw using a 4mm Allen key.
The collet with horizontal O-ring grooves is fitted into air chamber base.
▪ Re-new any worn or damaged radial cord seals and always renew both air chamber split
cord seals. Ensure there is sufficient cord to butt up to the sub-duct and the cable seal.
Note: Correct fitting of the cord seals is a major factor in air leakage from the air cham-
ber.
▪ Close the air chamber.
NOTE: The main seals in the air chamber consist of a 3mm cord seal, which is cut to
the correct length and permanently fixed with adhesive.
