4. Remove the o-rings from the four aluminum pistons taking care not to scratch the o-ring gland.
Clean the pistons thoroughly using a clean paper towel. Install the new greased o-rings
supplied in the rebuild kit.

3. Hold the reservoir under running water to flush
the fluid from the four chambers. While
supporting the reservoir, hold the tops of the
tubes under the running water to flush the
remaining fluid down through the tubes and
out of the chambers. Repeat this process until
the water runs clear. You will get some fluid on
your hands, but it is non-toxic and easily
washes off with soap and water. Wipe off the
outside of the reservoir and tubes with a clean
paper towel and use compressed air to gently
blow water out of the four chambers. You will
need to force air down through the tops of the
tubes to blow out any remaining water.
Repeat this process until all of the water is
removed. A very small amount of residual
moisture is acceptable if it can’t be completely
removed.

5. Before going to the next step, make sure that the tubes and o-rings are still fully seated in
the reservoir. If an o-ring pops loose, remove the tube, re-seat the o-ring and re-insert the tube.
The tubes are tightly fitted, so apply some additional grease to the beveled end of the tube (as
shown in step 6) and force it through the o-ring with a twisting motion until the tube can not be
pushed in any farther. When finished, all of the notches on the tubes should line up.
