operation.

Attaching the Gate Arm

1. Assemble the SG arm on the ground fi rst, making sure to leave all
fasteners loose, including the spreader arms (Parts #4 & #7).
2. Make sure the barrier gate is in the full closed position.
3. With someone's assistance, lift the arm up to a height even with
the barrier gate fl ange. The far end should either be supported by
something of equal height as the fl ange, or be held by someone
throughout the next steps.
4. Assemble the wood arms (#10) between the attachment channels
(#8) and the fl ange and bolt together. Tighten these bolts (#9) fi rmly.
5. Tighten all bolts (#3) where the three pieces of wood arm come
together.
6. Tighten up the nuts (#6) on the spreader arms (#4 & #7) until the
plates (#5) are tight against the wood.
7. The arm should have a curved, wishbone appearance once fi nished.
