• Install the top cap. There are two types of top caps:

- SNAP TYPE: The back of the top cap has levered snaps (follow instructions below)

- SCREW TYPE: The back of the top cap has deep bosses for screws (follow instructions on the next page)

TO INSTALL A SNAP TYPE TOP CAP (to install a screw type top cap, see the next page)

a) Place the top cap over the head assembly as shown, ensuring correct alignment.

b) Push the top cap down onto the head assembly to secure it in place. Ensure that the front tabs are aligned over the

nodules and the rear snaps are fully seated.

c) Push the snaps located at the back of the top cap to secure the top cap to the head assembly. Ensure that both snaps

are fully engaged.

Ensure correct alignment

so the top cap slides into

its secured position:

of the two protruding

tabs on the bottom of

the top assembly must

slide and then snap

over the corresponding

nodule on the side of

the head assembly.
