Cartridge Assembly Replacement

This cylinder is a pressure-containing vessel! Removing any parts while under pressure
could cause personal injury or equipment damage. Release the pressure from both ends of
the cylinder before attempting disassembly or repair.

1. To replace the Cylinder Cartridge (C15) assembly shut off the air supply.
2. Remove the Cylinder Cartridge (C15) by unscrewing it from the Cylinder Head (C16) with a spanner

wrench.

3. Once Cylinder Cartridge (C15) is threaded free from the Cylinder Head (C16), slide Cylinder Cartridge

(C15) all the way down the Piston Rod (C14) and off.

4. Replace it with a new Cylinder Cartridge (C15).
