ASSEMBLY STEP 3

Fasten the T-Rail to the Motor Unit

1. Place the opener on packing material to protect
the cover. For convenience, put a support under
the chain pulley bracket.
2. Remove the two 5/16"-18x1/2" washered bolts
mounted in the top of the motor unit.
3. Align the holes in the back section of the T-rail with
the holes in the motor unit.
4. Fasten the rail with the two washered bolts
previously removed. Tighten securely. Remember
to use only these bolts! Any other bolts will
cause serious damage to the opener.
5. Insert a 5/16"-18x7/8" hex bolt into the cover
protection bolt hole in the T-rail as shown. Tighten
securely with a 5/16" lock washer and nut.
NOTE: This bolt prevents trolley over-travel. Keep a
25 mm minimum between the trolley and this bolt
when adjusting travel limits (see page 29).
