Connect Door Arm to Trolley
Follow instructions which apply to your door type as illustrated
below and on the following page.
SECTIONAL DOORS ONLY
• Make sure garage door is fully closed. Pull the emergency
release handle to disconnect the outer trolley from the inner
trolley. Slide the outer trolley back (away from the door) about
5 cm as shown in Figures 1, 2 and 3.
• Figure 1:
– Fasten straight door arm section to outer trolley with the
5/16"x1" clevis pin. Secure the connection with a ring
fastener.
– Fasten curved section to the door bracket in the same way,
using the 5/16"x1-1/4" clevis pin.
IMPORTANT:
The groove on the straight door arm MUST face
away from the curved door arm (Figure 4).
• Figure 2:
– Bring arm sections together. Find two pairs of holes that line
up and join sections. Select holes as far apart as possible to
increase door arm rigidity.
• Figure 3, Hole alignment alternative:
– If holes in curved arm are above holes in straight arm,
disconnect straight arm. Cut about 15 cm from the solid end.
Reconnect to trolley with cut end down as shown.
– Bring arm sections together.
– Find two pairs of holes that line up and join with bolts, lock
washers and nuts.
• Proceed to Adjustment Step 1, page 29. Trolley will
re-engage automatically when opener is operated.
