INSTALLATION STEP 12

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 200mm as shown
in Figures 1, 2 and 3.

Figure 1:

• Fasten straight door arm section to outer trolley

with the 8mm x 25mm clevis pin. Secure the
connection with a ring fastener.

• Fasten curved section to the door bracket in the

same way, using the 8mmx 32mm clevis pin.

Figure 2:

• Bring arm sections together. Find two pairs of

holes that line up and join sections. If possible, use
the top and bottom holes on the curved door arm,
as shown.

Figure 3, Hole Alignment Alternative:

• If holes in curved arm are above holes in straight

arm, disconnect straight arm. Cut about 150mm
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

screws, lock washers and nuts.

• Pull the emergency release handle toward the

opener at a 45° angle so that the trolley release
arm is horizontal. Proceed to Adjustment Step 1,
page 25. Trolley will re-engage automatically when
opener is operated.
