Thread the black or gray cover and tighten with the face-‐hole tool until the cap is flush
with the top of the sprinkler drive assembly.
Note: The grey and black piston drive caps are
not
interchangeable and therefore must be
replaced with the same color cap.

Once a grey color cap is tightened, re-‐install the Torx or Philips-‐head fastener. If the
fastener cannot be tightened to be flush with the top of cap, then it is contacting one of
the molded ribs on top of the piston drive. Slightly tighten the cap with the face hole
tool. The rib locations are indicated with small detents molded in the sprinkler body as
shown is Figure 20-‐1.
