Maintenance
Reassembly
1. Reinsert the piston assembly into the lubricated cylinder. Ensure that the
motor screw engages into the hole in the center of the cylinder (see Figure
F.2.3d).
NOTE: To correctly orient the piston and cylinder assembly, ensure that the
lot number of the cylinder is facing up and the painted section of the piston
backplate is facing down. Also, care should be taken to keep the O-rings from
being pinched when inserting the pistons into the cylinder.
2. Cross Tube Replacement
Refer to the following figure and table for proper connection of cross tubes
from the tip fittings to the cylinder positions.
