• Some rear end caps on single-acting cylinders may contain speed adjusing screws. If so, remove and retain
the jam nut and spacer from both adjusting screws. Do not remove the adjusting screws. Remove and discard
the O-rings.
• Clean all metallic parts thoroughly with a solvent(mineral sprits recommended).

• Do not soak parts in solvent. Do not clean the spherical rod end bearing with solvent as this will remove
lubricant from the bearing.

Do not use trichlorethylene or chlorinated hydrocarbon solvents. Do not clean or soak O-rings or
other rubber components in solvent.

• Inspect the inside surface of the cylinder tube and replace if the I.D. is worn out or if there are deep scratches
or grooves on the inner surface.
