Maintenance
If signs of wear or breakdown of the mechanism occur, strip down and replace parts

into hole in disc and prise out. If the disc is metal, use an Ajax ladder key locating
in the 2 holes in the disc and unscrew anti-clockwise.
2. Unscrew nut "7" using a socket spanner and Knob "2" can then be removed.
3. Withdraw Bolt "4" and Spring "8" from the inside of the female instantaneous
body.
4. Check for signs of dirt, wear or corrosion of the Spring, clean the parts and
reassemble. If wear has occurred replace the affected parts with spares.
5. Reassemble the mechanism by reversing the foregoing instructions using a
lubricating grease on the Spring and the Bolt.
6. When tightening Nut "7" the tension on the spring is correct when the leading
edge of the curved face of Bolt "4" is level with the bolt hole edge as shown in
Dia. B above.
7. Check Seal "5" for dirt, cuts or damage to seal lip after cleaning. If damaged,
replace with spare seal.
