ASSEMBLY
Note: Clean every part before assembly. Keep parts clean and do not scratch during
assembly. Assembly can basically be done in the reverse order of disassembly. Make
sure parts are installed in the correct direction.
1. Lubricate the U-packing, O-ring, piston, cylinder and main valve with hydraulic oil
before assembly.
2. Place cylinder sleeve on the piston.
3. Insert the piston fully into the cylinder to its bottom position.
a. Make sure that all seals are positioned correctly and facing the right direction.
b. Handle seals very carefully in order not to cause scratches.
c. To avoid scratching the piston, the cylinder sleeve can be installed with a plastic
hammer or nylon bar.
4. Install the front cap on the cylinder.
5. Insert the main valve and the outer sleeve.
6. Apply hydraulic oil into the back cap for gas seal lubrication. See Figure 18.
7. Attach the back cap to the cylinder.
